It was my last week as a lecturer at Spring Grove Girl's College. I'd had a promotion and was due to move to a bigger university. I had a class of undergraduates I really enjoyed, not the least because all of them were girls! Many of them were more than attractive, but one of them topped them all ... Jessica was a real teenage sex bomb. She could easily have posed for a Penthouse centerfold, and the way she dressed did everything to enhance her sex-appeal even further. Her skimpy tops hugged around her freely bouncing firm boobs, clearly outlining her obviously bra-less tits. When she wasn't wearing a skimpy mini-skirt, her tight jeans would cling to her gorgeous body as a second skin. I could even see the outline of her pussy lips showing through them! Sometimes, she would wear skimpy skin-tight shorts, exposing the better part of her butts. But I must admit I was especially sensible to her spike heel sandals, which she always wore over her bare feet even on cold winter days. Honest, it was always hard for me to control myself when I looked at her. And when she had moved to sit in the front row, just across my desk, it had only become more difficult for me to keep concentrated on my teaching. It had gone to the point that I had to wear long shirts over my levi's in an attempt to hide my uncontrollable hard-ons. Watching her smile and slowly crossing and uncrossing her spiked-heel clad legs right in front of me was a show that would have me eagerly waiting for any opportunity to relieve my tension. That would usually be in the staff's toilets at the next break... When she wore one of her mini-skirts, I must confess I was often trying to catch a glimpse of her panties, if indeed she wore any. But her little leg uncrossing show would never give me a chance to glance that far up her thighs, and I was just left wondering...

Over time, Jessica had gotten more and more friendly with me. She used to walk up to my desk at break time, seemingly wanting advice about her coursework, or asking questions about some part of the previous class. This made my opportunities for a break to the staff's toilet even more sparse, but I must say I enjoyed her sexy presence. All the more when she went to sit on my desk in her mini-skirt, giving me a direct look up her thighs that would stop short just mere inches from the object of my desires! When the class resumed after that, I often felt her eyes glance at my crotch. I knew that from where she was seated, my long shirt was probably not enough to hide the tremendous erection caused by her little leg show.

Then one day, the talk got more personal. As she sat on my desk at the break, her white mini-skirt fully displaying her naked thighs, she asked me something on the line of: "Oh sir, you know I find you really cute? Your girl-friend must be real lucky!". I had to admit I'd split from my girl-friend the last summer, and she said: "Oh, what a shame! You must feel very lonely here then. I'm sure you'd enjoy some company, wouldn't you, sir?". I could only agree, but was at the same time reluctant to take it as a come-on. I thought having an affair with one of my students, even if she was over 18, would easily get me into trouble: "Well, sure, but you know ...". She interrupted me: "Oh yes, I can see that ...". As she glanced down at my crotch, I couldn't help wonder if she was referring to the uncontrollable hard-on that was poking even under my shirt... "... but maybe some small things could help you...", she went on, "You know, I remember this guy in high-school who'd always ask me for a pair of my panties ...". Foolishly, I couldn't help take the bait: "You'd give me a pair of yours?". She answered: "Oh no, silly, I couldn't, you know I never wear any, don't you?".

Her last words had my cock rocketing into high-gear. Resting her spiked-heel clad right foot above my knee, she added: "Would you like to have a look?". I stuttered: "W-well, I sure wouldn't mind...". She answered: "Oh, but first you have to be a real good boy. You know, my last test, I sure could use a better grade... Couldn't you just do a little magic and turn that C into an A?". As she spoke, her sole had found its way up my thigh and was resting right over my barely concealed erection. The sexy bitch was slowly massaging it right through my levi's, almost bringing me to the edge. I could hardly find my words as I stuttered "W-well, I must say you're very ... convincing. Consider it done!". She removed her foot, tracing the length of my cock with the tip of her heel as she said: "Well, that's a sweet boy! I'm sure you'll enjoy your reward!".

For all that, the little tease hadn't given me her promised pussy-flash yet. She bent over and lightly kissed my forehead as she said: "Oh, sir, you're really so cute. I'd really dream all my teachers were like you!". All I could answer was: "Oh, thanks. I find you very ... attractive, too!". I refrained from adding I wouldn't know what to do if all my students were like her... She answered: "Just attractive?", and as she looked down again at my bulging crotch, "Well, I can see I had quite an effect on you! Or was it my high-heels? You know, such a long day, I only wanted to rest my foot a while... I hope you don't think anything else of it... You wouldn't happen to have a little foot fetish, would you, sir? That would be so naughty of you, watching my spiked-heels as I sit across you in class! Well anyway, there's not much you can do about it, can you? Tssk, going to the toilets at break-time? That sounds so cheap!". I was speechless! She had seen right through me, up to the point of noticing the reason for my toilet jaunts. She went on: "You know, if you really want your reward, you must keep it all hard for me... Show me you're a real man, strong enough to resist the temptations of cheap jerk-offs in the toilets or at night in your shower... Oh, sir, would you do this for me?"

The sexy cock-teaser had me completely hooked in earnest for my reward, and I foolishly promised her: "Oh yes I would, Jessica, I will do just as you tell me.". She traced her heel back to my erection, raking my throbbing cock-head under the metal tip: "That's a good boy! Oh, there's one more thing I need to know, what jeans size are you wearing?". I answered, "Well, they're a 28/32, why would you want to know that?". She said: "You know, summer is coming, I think you could use more suitable clothes for the season... Well, see you next week anyway!"

I could hardly wait for our next class, but spent the whole week following my promise not to jack-off. Just thinking about what she'd done to me was giving me an almost constant hard-on, and there was nothing I could about it. When the next class finally came, I was glad to be wearing my longest shirt so my predicament wouldn't be too obvious. It was the penultimate class before summer vacation, and thus one of my last opportunities to enjoy Jessica's presence. As usual, she sat right in front of me in her high-heels sandals and mini-skirt, and had me crazy with arousal with her little leg show. I only had eyes for her. But she was quite cautious to leave the most interesting part to my imagination, seemingly postponing her pussy-flashing reward to some other time.

When the class ended, she walked to my desk, and sitting legs crossed above it, she asked me: "Well, sir, tell me, have you been a nice boy all this week?". I said: "Oh, yes, Jessica, I didn't do anything naughty!". As her right heel lifted up my shirt, displaying my tremendous boner, she commented: "That's a good boy! All hard and ready for me! I think you almost deserved your reward! But first, I have a little... uh, say, leaving present for you...". She removed her heel, not without lightly raking it down my erection which throbbed wildly at the touch. I was so aroused I almost felt like cumming right there. I mean, one full week of holding back was more than I'd ever coped with. Luckily, her raking didn't last long. She took a plastic bag out of her satchel and handed it to me: "This is your new summer suit. Be sure to wear it for me next week if you want your reward!". As I took the bag, she added: "Oh, one more thing! You know I don't wear any panties, don't you?" She didn't need to remind me of the all too present imagination of her naked pussy just waiting to be seen by my eager eyes. I nodded. "Well, sir, to be on equal grounds, I definitely expect you not to wear anything under that suit! Can you promise me?". In my present state, I was ready to promise her anything and quickly answered: "Yes, Jessica, I promise, I won't put any underwear". She stepped down from the desk and bent over, grabbing my throbbing hard cock and giving it a couple of nearly decisive strokes: "Such a sweet boy! And don't forget to keep it all for me as promised!"

The following week was an utter torture. I was foolishly keeping my first promise and getting hornier and hornier as every second passed, desperately needing some relief. But my second promise was starting to worry me even more. I'd opened the bag and checked out the suit. It was indeed a summer suit, all thin white cotton fabric. So thin it was nearly transparent. Honest, when I tried the pants with no underwear as she said, I could make out the darker outline of my pubic hair showing through. And worse, it was one size too small, tightly outlining my cock and balls in a way that left little to the imagination. My constant hard-on did nothing to alleviate the situation. I was hoping the shirt or jacket would give me some cover-up, but alas, both were just long enough to reach below the pant's belt, leaving everything beneath in full view. To make my condition less obvious, I'd tried to put my cock pointing upwards under the zipper. But the pants were so tight I just couldn't close the zipper when I did that, lest I risk catching the sensitive skin inside it. So I had to resign to leave it hanging down my left pant leg, where the bulge was more than obvious. That caused the fabric ro rub over it when I walked, making my arousal even worse. I tried putting on some underwear, but I immediately noticed how clearly their presence showed through the white fabric. Jessica would immediately know, and I didn't want to break my promise either. She had obviously planned her little tease down to every detail, and that suit left me completely exposed and helpless. I was thinking I'd been very foolish, but the expectation of Jessica's reward still had me ready for anything.

The morning before the last class, I had a long cold shower. It was the only way I could think would alleviate my arousal and allow me to wear the suit without too much embarassment. Even then, I had to walk with my brief-case held to cover my crotch, which was pretty awkward. I tried to concentrate on anything I could to distract me from the thought of Jessica's panty-less pussy eagerly waiting under her mini-skirt. I was trying everything to keep my arousal under control. I made sure to enter the class-room early, before any students had arrived, and went straight to sit at my desk. I was hoping I could just stay seated there the whole class, and thus avoid making a show of my condition. Jessica came in and sat across from me, wearing an even skimpier skirt than usual, her nipples jutting through a nearly transparent white halter-top. The spiked heels of her black strap-on sandals were about 5 inches high. As I saw her in this outfit, and despite all my previous efforts, my hard-on instantly rocketed into high-gear again. I just couldn't keep my eyes off her legs. After a while, I realized most of the other girls were also wearing their shortest mini-skirts, especially those in the front row. Everywhere I looked was getting my senses on fire, and it seemed I had nowhere to put my gaze where it could escape from that erotic overload.

My desk was on a platform above the others, and I knew Jessica had a direct view of my crotch from under it. Soon, I felt her eyes staring right at it as she licked her lips and smiled viciously at me. I knew she had noticed my helpless condition, and her reaction was only making it worse. My cock felt like a steel bar pulsating down my leg. As it was the last class before their exams, they'd asked me to do a bit of extra practice. That involved giving them some test questions and having them go to the blackboard to write down how they worked them out. The first girl who came up was Linda. She was the one sitting right of Jessica in the front row. She was wearing a particularly skimpy red vinyl mini-skirt along with a matching tight lace-on top that clearly showed her full cleavage. It was obvious she didn't wear a bra. That outfit would have been more than enough to give me a tremendous hard-on if I'd not already had one. But to top it up, the sexy bitch had chosen to wear it with a pair of red spiked heel sandals! I was literally starting to drool in sexual anticipation. And as I took a closer look at the other girls sitting in the front row, I could see everyone of them was wearing utterly sexy spiked heel sandals over their bare feet and legs. I couldn't help thinking Jessica had told them about my little foot fetish, and they'd all planned their outfit accordingly.

Linda started writing on the blackboard. I was barely paying attention to what she was writing, unable to keep my eyes off her sexy body. Then at one point she dropped the chalk and bent down to pick it up, facing away from me. As her vinyl mini-skirt hiked up her buttocks, I nearly lost my breath. The vicious little tease wasn't wearing any panties underneath and was giving me a clear flash of her naked bum! I felt my cock throbbing almost out of control inside my tight pants. As I looked at Jessica, I saw she was staring right at my crotch and was licking her lips with a naughty smile. I looked down, and my embarassment only got worse when I noticed drops of precum had started to seep through the thin white fabric over my bulging cock-head. At least, I was hoping she was the only one who could see my helpless situation. But then she raised her hand and said: "Sir, I'm not sure I understand what Linda wrote up here. Could you explain?". As I looked at the blackboard, I knew the explanation needed some more writing. In a desperate attempt, I asked the class if anybody would come up and write the missing piece. They stared at me with blank eyes, and no one volunteered. I tried to get Linda into doing it, but to no avail. Jessica said: "Sir, why don't you write it down for us on the blackboard?".

I had no choice but to get up and walk to the blackboard, knowing full well my predicament would then be visible to all the girls. I awkwardly stood up, trying to hide my situation as best as I could and face away from the class. I could feel the tight fabric of my pants rub over my hard-on as I walked, only giving me more stimulation. As I approached Linda, still standing there at the blackboard, she said: "Wow, sir, that's a nice suit you're wearing there!". She was staring right down at my bulging crotch. Her fingers traced up my left thigh, grazing over my steel-hard erection as she added: "I really like the fabric!". My cock throbbed at her touch. I was so aroused by now I almost felt like creaming my pants. I wasn't in a position to look, but I could feel the wetness of my precum dribbling down my thigh. I was hearing all the girls giggling, but wouldn't dare turn over to face them. I started writing down the missing part on the blackboard, but Jessica kept asking more questions, which I tried to answer by just turning my head. Then she said, "Oh, sir, you're gonna end up with a stiff neck if you keep turning your head like that! Why don't you just face us and explain it? Besides, I'm sure everyone here will enjoy a better look at your new suit!". The girls started giggling again, and I foolishly followed Jessica's advice, exposing my predicament to the entire class. One of the girls commented: "Wow, your pants are really so tight, wonder what you're wearing under them?". Before I could answer, Jessica said: "Oh, Liz! Can't you see the outline of his pubic hair? He's not wearing *anything* underneath! Isn't that so, sir?". I was speechless. Liz added: "Well, that's what I thought from the outline of his thingy there... I just wanted to make sure... Mind you, I don't wear any panties either!". Their talk was starting to get me seriously out of control, and my erection was jutting even more obviously down my left pant leg. I was afraid it would tear the thin fabric. Still standing at my side, Linda reached forward and squeezed my cock-head between her fingers. She said: "Uuhm, sir, I sure can feel you've got no underwear inside there! You should be careful now, accidents can easily happen!". Her expert fingers were now rubbing the underside of my cock-head. After two full weeks of holding back, her slow ministrations really had me on the brink of creaming my pants! She removed her hand, leaving my cock throbbing as I pondered her words. I'd already had the humiliation of letting my uncontrollable arousal be fully obvious to the entire class. And now, they were teasing me about losing it all in my pants! Given my lack of underwear and the thinness of the tight white fabric, I could only imagine how utterly embarassing this would be for me. I felt totally vulnerable, not knowing what to do to keep the worst from happening.

I almost felt relieved when the break finally came. I sat down at my desk, desperately trying to cool down and think about something else. But Jessica quickly walked up, and sat over my desk, her spiked heels dangling dangerously close to my still bulging erection. She said: "Uh, sir, I can see you've really been a good boy, following all my instructions as I said... You did keep it all for me, did you?". I answered: "Oh yes, Jessica, I've been keeping it all for you. But now I can't stand it anymore! When will I have my reward?". Jessica's right heel was now resting over my cock-head, slowly rubbing the underside. Her expert fondling had me on the edge of orgasm. She answered: "Well, sir, I see you've been really naughty with Linda! Looking at her bum as she picked the chalk and letting her fondle you right through your pants! Tssk! You know you should be more careful, you almost lost it for her when she did that, didn't you? Almost broke your promise to keep it all for me, uh?". I said: "Jessica, I'm just too aroused, you girls are driving me completely out of my mind!". The tip of her heel traced the wet spot of precum surrounding my cock-head as she commented: "Well, I sure can see we're having quite an effect on you! Just be careful it doesn't get any wetter!". Her left sole had moved to enclose my raging hard-on and was slowly stroking it up and down. I felt the surge of orgasm quickly building up. I was about to remove her feet from their explosive position, knowing I couldn't hold on any longer. My cock started twitching. Right at that moment, she withdrew her heels from my throbbing member, leaving me tethering on the brink of orgasm. I felt my cock give a couple of jolts, causing even more precum to dribble down my left thigh. The thin white fabric of my pants was now almost soaked with precum, and I didn't know how I would manage hiding it from the rest of the class. To make things even worse, Jessica commented: "You naughty boy! You nearly came into your pants, didn't you? You really like my heels that much? Well now, if you want your reward, you'll have to spend the rest of the class standing and facing us! No sneaky sitting at your desk and trying to hide your condition, uh?".

There was still a full hour to go before the end of class. I really wondered how I could manage the humiliation of showing my predicament to all those horny girls. All the more now that my precum had started obviously dripping through the white fabric of my pants. Jessica's torture was becoming unbearable. And still I couldn't help from foolishly following her orders, always in the hope of my promised reward. I stood facing the girls with my helpless hard-on seething down my pant leg, as I tried to concentrate and answer their questions. But the questions soon became out of control as well. Liz uncrossed her legs as she asked me: "Sir, you really have a wet spot showing through your pants there! Are you just sweating from the summer heat?". From where I was, I could see her exposed pubic hair under her mini-skirt. Linda drove one hand under her skimpy vinyl skirt and answered: "Oh, Liz, didn't you see how Jessica got him that hot during the break?". The movements of her hand obviously showed she was fingering herself. She closed her eyes, seemingly enjoying a potent orgasm. Liz said: "Oh, you mean masturbating him with her heels? Bringing him right to the edge of cumming into his pants? I'd sure like to do that too!". Opening her eyes, Linda answered: "Well, I'm sure he's got a little foot fetish. All the time I was at the blackboard, I could see him staring at my high-heels!". Liz raised her legs and put them on her desk. I was just able to catch a glimpse of her fully naked pussy before she covered it with her hand and started fingering herself. She said: "Can't you see he's also trying to look under our skirts and see if we're wearing any panties? That's really naughty! If I were Jessica, I wouldn't give him his reward!". I was now totally out of control. Every word they were saying only caused my hard-on to grow even larger, and the way they were fingering themselves right in front of me did nothing to alleviate my arousal. Linda uncrossed her legs, now revealing her naked pussy, dripping love juices under her red vinyl micro-skirt. The sight almost had me erupt, and I could barely control the throbbing of my cock. She said: "Do you think he noticed I wasn't wearing any panties when I picked up the chalk?". I watched open-mouthed as she fingered herself to another orgasm. Jessica commented: "Be careful, Linda, did you see how his cock twitched when you flashed your pussy at him? You wouldn't want to have him cream his pants just watching you, don't you?". Linda answered: "Well, that might be fun! Can you imagine how embarassing it would be for him?". Liz added: "Oh, yeah, so embarassing! I mean, he's totally exposed there in his thin white pants! And with no underwear to protect him, it would really be such a mess!".

It was Liz's turn to go to the blackboard. She dropped her chalk several times, every time bending away from me to pick it up and flashing me her pantyless bum. As I stood a few steps from her, my steel-hard member kept pulsating at the show she was making. And turning my gaze towards the class didn't help it. Linda now had her legs resting on her table, fully exposing her naked pussy. She was pointing her red spike heels at me while still busy fingering herself under her vinyl skirt. Jessica said: "Sir, you're being naughty again! Trying to peek under Liz's skirt when she picks up the chalk, uh?". Liz turned back to me, staring at my throbbing hard-on: "Oh, sir, you enjoy seeing my naked bum, don't you?". She reached over with her right hand, grabbing my oozing cock-head through the thin cotton. "Oh, yes, I can feel your thingy's all wet there! Try to control yourself, sir! You heard what I told Linda about your lack of protection, didn't you?". She proceeded to slowly rub my cock-head between her fingers, nearly bringing me over the edge. "You know, it would be so embarassing for you if you came in your pants, uh?". Her finger-nails were now expertly raking the sensitive underside of my throbbing cock-head. I couldn't believe how she performed her ministrations right in full view of all the girls. As my cock started twitching nearly out of control, I heard Jessica's voice: "Liz, be careful now, I think you've got him right on the brink!". Liz removed her hand just a split second before I'd reach the point of no return. My cock kept throbbing wildly, dribbling ever more precum. Linda was staring right at it as she said: "Wow, Liz, that was s-ooo close! You really had him about to ejaculate into his pants there, didn't you?". Liz answered: "Uhmm, I think he's very naughty! I mean, can't you see he let me masturbate him right through his pants in front of all you girls? Tssk, he could really have lost it and made a total mess of himself!"

I felt I couldn't take any more, but then Linda said: "Oh, sir, can you please come here, there's something I want to show you...". I stepped down the platform, standing in front of Linda's table. I was unable to keep my eyes off her exposed pussy. I said: "Yes, Linda, what is it?". Still busy fingering herself, she answered: "Well, I understand you like my sandals, don't you? I thought maybe you'd enjoy a closer look?". With that, she raised her right foot, moving it towards my crotch. I felt the tip of her heel come to rest on my thigh, some fraction of an inch from my bulging cock-head. As she traced little circles there, she caused the tight fabric to echo her movements and rub over my pulsating member. I felt like jolts of electricity travelling up my shaft as she'd now moved the spiked tip of her heel right to the underside of my cock-head. In just a few expert strokes, the vicious bitch had me right on the edge. My cock was throbbing with uncontained arousal, getting even harder as it strained against her heel to increase the pressure of her light rubbing. I heard Jessica say: "Wow, Linda, I can see you've got him almost there now! He sure seems to enjoy the way you tease his cock-head with your spiked heel, doesn't he?". As she increased the pressure, Linda answered: "Oh, Jessica, you know my heel isn't just teasing him there! Can't you see I'm actually masturbating him right through his thin white pants?". Liz added: "Tssk, such a naughty boy! Letting Linda jack him off with her heel in front of everybody! I wonder how long he can resist that ...". Linda said: "Oh, Liz, I'm sure he's desperate to cum, by now! Wouldn't that be fun if he soaked his whole pant leg while I had him spurt with my heel?". Jessica answered: "Oh, Linda! You know how embarassing that would be for him, don't you? Remember he's got no protection under there!". Fastening the pace of her expert ministrations, Linda said: "Oh yes, I know that, Jessica! I mean, his lack of underwear is more than obvious, isn't it? Don't you think that would make it even more fun? Besides, it makes it so much easier for my heel to find all his sensitive spots! That thin white cotton just shows every detail, and I can see his slightest reaction!". Liz added: "Oh yes, and I'm also sure it makes the sensation even more intense for him! Isn't that so, sir?". She turned to me: "Don't you like the feeling of Linda's spiked heel, masturbating you right through your tight pants? With just that thin layer of white cotton to protect your cock-head from her expert manipulations? I'm sure the sensation must be overwhelming, uh, sir?".

It was indeed overwhelming, and Linda almost had me past the point of no return. I pleaded: "Linda, please, please stop now. I really can't hold back any longer!". Her eyes locked on my crotch as she said: "Stop? Why, sir? Aren't you dying to get some relief? You've been holding it two weeks for Jessica, haven't you?". I felt my cock twitching under her heel. I really thought it was too late. At that precise moment, she removed her heel from my cock-head, letting it rest an inch apart motionless over my thigh. She said: "Well, if that's what you want...". I felt my cock give a couple of pre-orgasmic jolts and then stand tethering on the edge of ejaculation for several endless seconds. Then the alert was over and I started breathing again. As she resumed tracing my steel-hard member with her heel, Linda commented: "Wow, sir! You almost creamed your pants there, didn't you? Is that how Jessica got you so wet at the break? Playing with your cock-head with her heels?". Jessica said: "Tssk, sir, you're really being naughty! Didn't I tell you to save it for me? See how wet Linda's got you now!". As I looked down at my left thigh, I could indeed see the 2-inch wide spot of precum oozing through the fabric just below my cock-head. There was still half an hour to go, and all I could hope was it would have time to dry up by then. At least, the worst had been avoided for now.

The next 15 minutes were spent with Jessica going up to the blackboard. Once again, I only had eyes for her. As I stood beside her, facing the class, I could hear all the girls giggling, pursuing their sexy comments about my predicament. Jessica kept dropping her chalk and bending over to pick it up. But the little tease made sure she faced towards me while bending, so I couldn't see under her skirt. Astonishingly, this was having me even more aroused than if she'd actually showed me her bum. To make matters worse, Liz started commenting: "Oh, Jessica, can you see how he's trying to look when you bend over? I'm sure he's dying to know if you wear any panties underneath there, isn't he? Why don't you give him just a little flash?". Jessica answered: "Oh, I'm not sure if he deserves his reward yet, you know! He's been very naughty with you and Linda, hasn't he? Letting you masturbate him right through his tight pants as I was watching, uh? I wonder if that might help him...". Jessica walked to her table and took out a small bottle from her bag. She came back to me, and poured several drops of its contents over her fingertips. I wondered what she was doing. But then her hand reached forward and grabbed my bulging cock-head as she said: "This lotion there should make his cock even more sensitive, you know!". Her fingertips were thoroughly spreading the oily lotion all over the underside of my cock-head. I felt a tingling, burning sensation as it worked its way through the thin fabric and reached my naked skin. Indeed, it was causing my cock to grow even harder, while the tingling had me almost over the edge. With the combined lubricating effect of my precum and the oily lotion, Jessica's expert rubbing was already about to have me explode. She removed her hand just as my cock started twitching. Linda said: "Wow, Jessica, you had him right about to spurt in his pants again, didn't you? I see your lotion seems quite efficient! I wonder if he'll resist much longer, now!". Jessica moved her fingers back to their maddening position, slowly raking the underside of my cock-head with her nails. I was once again on the brink. I heard Liz commenting: "Oh, Jessica, the way you're masturbating him with your finger-nails right through his thin pants! You've got him right about to helplessly soak them, don't you?". I was desperately trying to hold back, but Jessica's expert ministrations were having the most of me. Once again, my cock started twitching and Jessica removed her hand at the last possible moment. I felt another pre-orgasmic jolt animate my shaft. My precum was helplessly dribbling. Jessica poured some more lotion over her fingers and grabbed my bulging cock-head, squeezing it between her fingers. I could hear a slurping sound and feel how wet the fabric had become. She walked back to sit at her table as Linda said: "Wow, Jessica, see that huge wet spot over his cock-head? Looks like you had him start cumming for you, didn't you?". I couldn't help look down and see the wet spot of precum was indeed now almost 3 inches wide. It was a hot summer day, and I was desperately hoping even that would have time to dry in the 15 minutes that remained...

As I stood facing Jessica, I could feel the tingling of her lotion stimulating the underside of my cock-head. Despite all my efforts to regain control, the sensation kept me tethering on the edge of orgasm. Jessica looked me right in the eyes and told me: "Sir, you've been waiting two full weeks to cum for me, haven't you? Do you think you can control yourself now and have your reward?". Her gaze had me as hypnotized. I felt totally under her control. I watched in a trance as she uncrossed her legs, finally revealing her panty-less pussy to my eager eyes. My steel-hard cock kept throbbing as I watched, seemingly animated with a will of its own. As the lotion seeped through the fabric, the tingling in my cock-head was getting ever more intense. Linda said: "Oh, Jessica! Can you see how his cock's throbbing? I'm sure he's sneaked a look under your skirt and noticed you didn't wear any panties!". Liz added: "Oh, yes, he must be happy with his reward, now! Wonder how long he can resist the effect of your lotion!". Jessica started fingering herself. Her heels were rubbing over the table leg as she looked right at my crotch. As if I needed any more cue, Linda commented: "Wow, Jessica, the way you're moving your heels over that table shaft! I'm sure it has him feel as if you were masturbating him right through his pants!". It was indeed the case. Her lotion already had me on the edge, and each stroke of her heels was pushing me farther across. Her free hand took a lollipop and proceeded to suck it as she stared at my throbbing hard-on. I heard Liz commenting: "Oh, Jessica! That's so wicked! The way you suck on that lollipop! You really want to have him think as if it were his bulging cock-head, don't you? Be careful you don't make him squirt in his pants like that, uh?"

The feeling on my cock was now getting me in total sensory overload. Even if she wasn't touching me, I couldn't help feeling she was at the same time masturbating me with her heels and giving me a blow-job right through my pants. My cock started twitching uncontrollably. I barely heard Linda say: "Oh, Jessica, you've got him right there!". I knew all these horny cock-teasers were watching and I tried to hold back, not wanting to make a complete fool of myself. But it was too late! For all my desperate efforts, I couldn't control it anymore and felt my cum helplessly erupt as Jessica had me ejaculate into my pants! As I stood there in full view of all the girls, I felt my cock jolt and jolt, spurting load after load of accumulated semen down my thigh. My orgasm was totally out of this world, more powerful than anything I'd ever experienced.

As I came back to reality, all the girls were giggling at me. Liz was saying: "Wow, Jessica, you really had him soak them big time, didn't you? Two full weeks worth of his juice wasted right into his pants!". Linda added: "Oh, sir, you couldn't control yourself, could you? What are you gonna do now? I mean, your pants as so soaked! You don't have a spare pair, have you?" As I looked down, I indeed realized how embarrassing my situation was. My left pant thigh was completely soaked with cum down to my knee, and I was still standing in front of all the girls who were giggling even more loudly now at the sight of my predicament. And as I started thinking about what had happened, and looked at Jessica's vicious smile and exposed pussy once again, I couldn't help my hard-on from slowly expanding again. It was the end of class, and my only option now was to wait long enough for my pants to dry before I could walk out of the room. Jessica walked to me and grabbed my growing hard-on inside her expert hand. As she proceeded to deftly masturbate me through the soaked fabric, she said: "Well, sir, I'm sure you enjoyed your little reward, didn't you?". I still could feel the tingling of her lotion and her vicious ministrations soon had me rock-hard again. Her expert rubbing was about to bring me over the edge. My cock started twitching. She removed her hand right at that moment and added: "Sorry I can't leave you a pair of my panties... You saw for yourself I don't wear any!". Then she said: "And I really like your suit when it gets that wet for me!". She walked away, leaving me in my utterly embarassing state, my hard-on still protruding through the soaked white fabric of my tight pants. I had to wait until the night had come to try and walk out of the classroom without anybody noticing my condition...
