Island Revenge

"Here's a drink, Mark. I'm sorry about how I acted earlier. I didn't mean to imply you weren't a man. I was just saying you didn't have the body of the other guys here."
"I appreciate that, Julia," I said in a conciliatory manner. "I can't help genetics. I'm scrawny. I might fill out more when I get older but this is me for now. Besides, body strength isn't everything. Being smart can be important too."
"I was just trying to make a point. I didn't know you were so sensitive about it. Our group didn't come on a summer-long vacation to this tropical island, so we could have more problems on the first day. So drink up and let's forget all about it."
I downed half of it to show I had no hard feelings. There was alcohol in it, something I did not usually get access to when at my parent's house. She went back to the group and I went foraging for wood. Four boys and six girls, on a two-month long vacation, on a big tropical island. There was plenty of food and several huts all over. We had chosen a grouping of huts as our camp and it was my job to find wood for the main camp fire.
An hour later, after supper, we were sitting around the fire when Julia stood up in front of us all. She certainly was gorgeous in her tight bikini.
"I've got a fun game for the boys, to start off our evening. It's an all-or-nothing thing and it has risks and rewards, so all four of you have to be in from the start, if any of you want to play. No backing out after that. If you are the one who ends up losing, you'll take your punishment. I guarantee it'll be more pleasurable than you expect. What do you say, guys?"
The others were in and looking at me before I had a chance to think. I agreed to play the game, more to appease them than anything else.
"All right. I want the girls to move over on this side of the fire, so we can all look at the guys."
We waited until they shuffled around.
"Now strip, guys. Go on. Take it all off. None of you have anything we haven't seen before."
The girls giggled, looking at each other briefly. I felt terribly self-conscious stripping in front of everyone but, again, bent to the group will. Dropping my underwear was very difficult. I had always been worried I'd get an erection in front of others while naked. It was why I never took a shower after gym class. To make it worse, my cock felt like I'd taken some type of drug. All excited and tumescent, ready for the slightest excuse to swell.
"Good. Now I want you four to stand there, in a row, and not move. I'm going to talk and you're going to listen and not say a word. If you are confident and in control of yourself, you have nothing to worry about. What I want is to make one of you grow erect."
My cock jumped at her words. I struggled to keep myself limp. What was wrong with me?
"The first of you who becomes fully erect will be the loser. That's it. The first one of you to get a boner in front of us will lose. If you do lose, I'm going to inject a DNA black market alterator in you and it will make you become a compulsive masturbator. It will change your genetic make-up, forcing you to physically crave masturbation. You will be sent away, to live on your own for the whole summer, to explore your new masturbating self. Only someone who is turned on by this idea would get erect at my words."
I was sure the drink she'd given me had been drugged. My cock was growing, no matter what I wanted, needing only the mention of a fantasy to get going. No matter what I did, I was becoming erect.
The other guys noticed and smirked. The girls pointed at me and giggled even louder.
"I think we have a winner, er, I mean loser. Move closer, Mark, so we can all see your erect penis."
Julia's every word drove my cock into further drug-induced rigidity and I moved away from the group with a huge erection jutting out in front of me. I felt terribly embarrassed. Everyone was laughing. Julia kneeled in front of my rigid penis. Before I could react, she lifted it up with her left hand and I felt a quick pinprick then a hot jet flood into my shaft. She dropped my erection with a look of disgust on her face, wiping her hand on the ground, and stood up.
"There, all done. The injection is in and there's nothing you can do about it. Now come with me and I'll take you to your new hut. You're only to come back here when you bring in the wood tomorrow, not any other time. You are not to talk to any of us until the end of the summer before we leave. That will be enough time for the alterator to complete its work. You will go home a compulsive masturbator for the rest of your life and we will all know it. Now, come along."
Stunned, laughter ringing in my ears and shame flooding my cheeks, I hurried to follow her, naked and rigidly erect. She was carrying a torch so I had to follow her; it was too dark to do otherwise. My cock felt very hot and hard, throbbing with every step. I ignored it, concentrating on not tripping in the dark.
"Here we are."
"You set me up. That whole game was rigged. I'll bet the other guys knew about the drugged drink you slipped me."
"Of course they did. You were a fifth wheel, Mark. Four guys, six women. Do the math. You had to go. Now you will be out of the way. Get in there."
I hurried past her into the hut, my cock bobbing in front of me.
"I told you I'd get rid of you, Mark and I meant it. No one wanted you, especially me. Now you'll get to console yourself by playing with your penis. It will become your new love. Isn't that great? Enjoy your time here. It should be very pleasurable, as I promised. To help you, I added another DNA alterator to the dose. You should feel stoned most of the time. It will help pass the time while you resist the desire to masturbate. By the by, the main effect you can expect is a bothersome fluttering all over the shaft of your penis. It will get more intense as the days pass. I'm told the only move to get rid of the feeling is a slow and steady stroke up and down the shaft of your penis. Oh, the alterator might make it difficult for you to orgasm. So you may often have to masturbate without ejaculation. I'm told all ejaculation will now be involuntary, occurring when your balls are full."
She smiled, looking at my boner.
"I was surprised at the size of your erection. It's magnificent really. It probably made the other men jealous. Unfortunately for you, DNA-ALT-5701 is set to bring your penis length within parameters acceptable for masturbating losers like you. I believe the maximum length allowed is four inches. Enough to masturbate, but not enough to fuck properly. On that note, the fluttering will not be relieved by contact with others. It will get worse, in fact. Forget fucking women. Utterly unbearable. So masturbation will be your only option for relief. Use your big brain to figure a way out of this, you loser. We'll see how you fare in two months. To think you had the gall to make a pass at me. How could you think I would be interested in such a skinny bean pole like you? Now you'll have your own skinny pole to occupy your life. Your penis, you sick pervert. Now, you'll leave all women alone."
She left me sitting in the dark, my hot cock erect and throbbing. I felt very dizzy and passed out.

***

I woke alone in my hut, early next morning, depressed. I had a morning pee hard on. I hurried outside. No one around. I'd have to get used to being naked. Julia hadn't given me my clothes back. Peeing proved difficult, my erection tightening the bladder muscles. I ended up shooting several hard jets of urine around the landscape. Thank god I was alone. No one saw that.
My penis did not soften after. I tried to ignore it and get down to the job of looking for dead wood for the other camp. I felt like I had been relayed to slave status. And what was that business about compulsive masturbation? That couldn't have been real, could it?
I looked down at my rigid erection.
It should have softened by now, so that wasn't normal. I didn't feel any fluttering though. That bitch. Julia had hated me from that day at school when I admitted my love for her. I should have known coming here was a bad idea. That game of hers was crazy. She injected me before I even knew she was doing it. Now it was too late. I was on the outs with everybody, a DNA alterator flowing through my veins. Where the hell did she get that? No way she found it on the island. And that drug in the drink. She planned to do this.
I felt an odd flutter along the shaft of my penis.
It was so quickly gone, I wasn't sure I had felt it. It was weird, like fingers lightly touching my cock here and there, going up the shaft, moving from one side to the other and back again.
There it was again, continuing up the shaft, a long, slow flutter.
The inexorable ascent up my shaft drove my penis into utter rigidity. The feeling drew my attention inexorably, my every thought fixated on the fluttering. I realized I'd been standing there like an idiot, my erection jutting straight out. God, there was the fluttering starting from the bottom again.
I shook my hips to rid myself of the feeling. The fluttering stayed with me, matching my every gyration, never missing a beat. The only result was a further hardening of my penis. I felt sluggish everywhere else, even in my head. My thoughts were foggy. I felt pleasurable all over my body. My penis throbbed, the fluttering done its ark and going back down. When would it stop? It was unbearable. I couldn't think of anything else.
This had to be the effect Julia had talked about. God, it was brutal and this was only morning of the first day. I resolved not to give in to it. That road would only lead to compulsive masturbation. I would not let her win that quickly. Still it was easier said than done. The fluttering was getting stronger with every passing hour.
It made thinking very difficult. Every task became doubled, shared with thoughts about my fluttering shaft. My penis was almost always rigid. If anyone was here, they would be laughing at my uncontrollable erections. After six hours, I had gathered no wood, either sitting or standing, looking at my rigid cock and doing everything I could not to touch it.
"There you are. What have you been doing all day? We're going to need our wood. I see all you've been doing is paying attention to your own wood."
Julia was walking towards me. My cock was fluttering like mad, jutting rigidly, a bar of steel, and I felt incredibly self-conscious. I'd been about to give in. Could I now stop myself in her presence? I didn't want to give her the satisfaction.
"Look at you, all rigid and everything. Very nice. It tells me how far along the alterator is. I bet you've been trying to stop yourself from masturbating all morning, instead of doing your chores. Give it up. They found some guy who had that fluttering, extracted the right strands of DNA, duplicated it and added it to a virus. It is changing your DNA, right now, converting one tiny section of it, to give you that guy's fluttering penis. So do you know what the rate of success is for DNA alterators? It's one hundred percent. No exceptions. Face the fact. You will become a compulsive masturbator. May as well not torture yourself about it. Just masturbate. I'll bet the fluttering is driving you up the wall anyway."
She was smiling, looking at my rigid cock bobbing up and down. I was fuming. I had to get control somehow but I couldn't. My mind was too foggy and the fluttering was pulling at my attention, going up and down my shaft. It had to stop.
"Look. Just masturbate right now. I won't say anything to the others. It might even relieve some pressure and you could go soft. You can't do any work like this. Go ahead, put your hand on your shaft and rub it. Do it, Mark. Do it," she said, leering.
My hand was hovering over my cock. She was winning. I was going to do this.
"That's it, Mark, rub it, relieve the pressure. Just let your hand make contact. Get that part over with. Touch your penis."
My fingers encircled my shaft and I stroked once. An insane relief rushed over me as the rubbing overcame the fluttering. The moment I stopped stroking, the fluttering was back and I stroked again, desperately, settling into a slow, steady movement, my fingers lightly sliding over the shaft. It felt so good, giving me pleasure and relief.
"Keep stroking. You'll see, it's worth it," she laughed, condescension dripping from her every word. "You'll be able to think better and do your job. We expect to see you in two hours, with a load of wood. Bye-Bye. I'm glad I saw you start jerking. Now, you'll never be able to refuse doing it. You know what relief it gives you. There's nothing like it."
She left me standing there, my hand slowly rubbing my shaft up and down, feeling incredibly embarrassed and aroused. Damn that bitch. It felt so good. Anything was better than that damn fluttering. Damn it, damn it. I'd wanted to object, to argue but I couldn't say a word to her. All I could do was masturbate.
I rubbed my cock for another hour. That's right. It took me an hour to get my hand off my cock. I had to scramble around like mad after that, ignoring the constant fluttering in my penis, grabbing wood from anywhere. I finished just in time, carrying the pile balanced over my shoulder in a bundle. My penis preceded me, jutting rigidly. It never softened.
The guys saw me and laughed at my uncontrollable rigidness, though they too were curiously erect. The girls were naked and playing with each other, looking at my erection and giggling. The three men were lying naked in deck chairs by the pool, staring into space, stupid grins on their faces, their penises all standing at attention. What was going on here? I dropped the bundle and made to leave.
"Just a minute, boy. Put some wood in the hearth, before you go."
Once again, I had to do it, pretending my erection wasn't there and ignoring the fluttering drawing at my attention. Why couldn't I refuse their orders? All I wanted to do was rub my cock. I just could not let myself do it in front of them. It would give Julia too much satisfaction. The sooner I did what they asked, the sooner I could go. The wood placed in the hearth, I stood, the fluttering worse than ever. It was stronger than this afternoon. My hand wavered, sneaking uncontrollably towards my jutting penis. I managed to stop myself just in time, pulling my hand back, my cock bobbing in disappointment.
The fluttering came back with a vengeance. I had to get out of here, or I was going to masturbate in front of them. Holding back tears, I ran out of their camp, laughter jeering me on, my cock jumping back and forth with every step. Far away from them, I stopped, leaning against a palm tree and sobbed my heart out. Why had this happened to me?
I stood back from the tree and wiped the tears from my eyes then resolutely brought my hand to my shaft and rubbed it. Relief flooded me and a sigh escaped my lips. I rubbed the shaft slowly, letting the delightful stroking overtake me. There really wasn't anything like it. Nothing compared to masturbation now. It was better than before, so intense.
I started walking again, my hand keeping pace with my every step until I found a rhythm that worked. I fell into a daze, the pleasure from masturbation flooding my senses like a drug. Why would I ever fight masturbation? I knew I should show some restraint but masturbation was a normal every-day activity. As well, I was alone, with no one to question my personal needs and how I chose to satisfy them.
I reached my camp, put water in the kettle, and put it on the stove. My hand never stopped pumping my rigid shaft. I was sitting in my chair, teacup in one hand, penis in the other, slowly rubbing, when I came to a realisation. I couldn't stop masturbating. The thought of going back to the fluttering was unacceptable.
What followed was an evening of debauchery. I abandoned myself to slow, regular stroking, masturbating the entire evening away. I felt on the edge of orgasm, kept there all night by my fingers. No one else would take this long to pleasure me. No one else knew how to touch my penis like this. It was so rigid, it felt so good. I finally ejaculated, a huge release of semen that covered my chest with cum. Satisfied, I fell asleep.
I was awakened next morning by the fluttering. I was laying on my bed, my cock already rigid and throbbing, the fluttering stronger than ever, lightly tickling my shaft, sliding left and right. It kept going up and down, never stopping, never speeding up. The feeling was so strong, every other perception faded in comparison.
With a moan, I slid my hand over my cock and rubbed, feeling the instant relief as the fluttering vanished. Stroking felt much better than yesterday. Every little touch turned into an overwhelming, pleasure-filled sensation, making it hard to keep from moaning. I felt dizzy, my thoughts swirling through a fog.
The second DNA alterator Julia was keeping me stoned, more evidence of planning on her part. Every perception was covered with a sheen of pleasure, enhancing the sexual effects of the first DNA alterator. It made resisting my condition more difficult. I lay there, pumping my cock, until my bladder forced me to get up.
I tried to urinate without masturbating but the fluttering made it impossible to release. I ended up stroking extremely slowly, keeping my mind blank and working at my bladder muscles to let go. I spurt a large quantity of hard urine jets that shot strongly into the air. I could not urinate any other way. It might be okay on a beach but this was going to be messy back home in the bathroom.
A blast of hatred went through me for Julia, my romantic feelings utterly eradicated. I'd never had a chance with her. Since that day when I admitted my interest, she'd had it in for me, denigrating me endlessly at school. Yet, despite all the evidence of her disgust, I had allowed her to con me into becoming part of this vacation group.
Julia wanted to do this, to destroy me. She wanted to take away any chance I had of ever finding a woman by forcing me to become a pervert, craving constant masturbation, her twisted way of getting even with me for desiring her.
The question was, as I lay here, masturbating slowly and regularly, could I stop her from achieving her goals? I didn't think so, from the effects I'd experienced so far. The fluttering was real. It was unbearable and getting stronger. My libido felt charged up and my penis tended to become erect uncontrollably. When it was erect, it always jutted out as stiffly as possible. Bending it was impossible. Even if I had clothes, my penis would have to be let out.
My mind felt foggy and pleasurable, as if I'd smoked a doobie. It made the need to masturbate constantly worse. I couldn't think properly. My horniness kept taking over and I'd pass another hour just rubbing my cock. A bigger problem was that I was alone here. There was no one to stop me, no one to make me embarrassed by my constant masturbation.
If I stayed here all summer, I wouldn't be able to stop masturbating at all. If I'd been at home, having to go to school and do homework, I would have reasons to control the insane urges. Here, there was nothing. Just me and my hand.
I fell asleep, my hand rubbing my cock slowly, almost unconsciously.

***

I woke the next day, feeling even foggier. I could hardly get my thoughts together. All I could think of was the fluttering up and down my rigid shaft. I tried to focus on something, anything, but failed, my thoughts always returning to my shaft and the fluttering. The sensation wouldn't stop, moving from side to side of my shaft, driving my penis into rigidity.
Before I knew it, my hand had moved instinctively to it and started rubbing. Instantly the fluttering vanished, replaced by a wonderful pleasure, as my fingers slid slowly up and down. I had to keep a steady regular pace or the fluttering would return. I lay there, masturbating mindlessly, simply feeling the pleasurable sensations in my cock.
At some point, I wondered how long I had been masturbating. The sun in the sky was high, near noon. I suspected I'd been rubbing my cock for at least two hours. I took my hand off my rigid penis resolutely. I was not going to masturbate the entire day away. I stood and went to eat some fruit for breakfast. I felt completely stoned, unable to think about anything for long. The fluttering was back and it made doing anything impossible. I sat down on the sand and leaned on a tree, looking down at my still rigid shaft.
I needed to cum. I gave in to the craving and jerked my cock as hard as I could. The fluttering came back, breaking my rhythm. It only vanished if I masturbated slowly and regularly. I could not bring myself to orgasm. I could only rub slowly, it was the only thing that worked.
Once again, I abandoned myself to masturbation, going into a mindless trance, floating on the wave of endless rubbing sensation. I had been at it for hours when a cough made me open my eyes and pull my hand away from my rigid penis in embarrassment.
"Isn't this a nice sight. I see the DNA alterator is doing its usual good job. I'll bet you've been masturbating for hours. Good news. I came to tell you we won't need you to bring wood anymore. I've got the guys in the camp doing it. I figure it will soon be too hard to get you to do anything else except jerk off, anyway. So I'm going to leave you now, so you can get back to having fun for the rest of the summer. I'll be back in seven weeks, to pick you up for your plane back to school and your parent's house. Won't that be great? Ta-tahh."
She left me without a backward glance. I sat there, utterly depressed. My cock had never wavered through it all, embarrassing me with its uncontrollable and inappropriate rigidity. I refused to touch it for a while, to punish it for what it was doing to me but I could not keep up the anger. The fluttering kept increasing, making my thoughts waver and break up. At some point I could stand it no more and returned to steady masturbation.

CHAPTER TWO

I'd been on the island for almost two weeks when my DNA changes finally stabilised. I was powerfully stoned all the time and the fluttering had grown to powerful levels. It was utterly unbearable. I was forced to rub my shaft no matter what I wanted. Orgasms were far and few between, my balls always swollen and full of cum, aching to shoot. I just couldn't keep a fast enough rhythm to get there.
As predicted by Julia, my penis had also begun to shorten. I hadn't noticed it the first few days but after thirteen days it was down to six inches from eight. It was an alarming and embarrassing change. Even though I had a scrawny figure, I'd always been proud of my large penis. Now pride was turning to shame as my penis kept getting smaller. The girth, the length, all had gone down.
It was what drove me out of my masturbatory trance for the first time in days. I had to do something before it was down to the four inches the DNA dictated. I decided to sneak back to Julia's camp and see if I couldn't find anything to help me. There was always the chance of getting caught but what else could they do to me?
I waited till dusk and hurried to the camp before the waning light completely vanished. Of course, I masturbated the whole way. I slowed down by the edge of camp, hand on cock, and hid behind a palm tree. I stroked slowly while checking out the wild scene in front of me.
The three men were still lying on the long-chairs. Julia and two other women were on top, screwing them slowly. The men said nothing, staring out into space with vapid grins on their faces. I decided to sneak into Julia's hut while they were busy. Pulling back into the shadows behind the palm tree, I hurried around the camp, masturbating faster.
Sneaking into her hut had my heart pumping and my hand stroking the slowest it could go. Inside, I saw nothing obvious so I started opening drawers and closet doors. I saw her suitcase and pulled it out of the closet. I snapped the toggles open, the anticipation pushing me to stroke the fastest I could without incurring the fluttering.
Inside, I found what I was looking for. There was a package with several bottles and syringes. I took it out, returned the suitcase to the closet and sneaked back out, my cock throbbing with the excitement. I had to stop along the way back to my hut, so I could have a good masturbation session.
Back into my hut, I opened the package and examined the contents. There were five small bottles. One had my name on it, so I knew what that was. No way I was injecting more of that into me. Another had the generic word on it 'guys'. I figured it explained their weird behaviour and permanent hard-ons. She had probably injected all of them already.
The next bottle had the word 'girls' on it. I wasn't sure what it would do to them, but I could guess. Probably drive their libido through the roof, make them crave sex. I had thought Julia had come here to punish me but now it appeared as if she had been planning much more than that. What was she up to?
The next two bottles weren't helpful. The first had a label 'Stoner' and the other 'Boobies'. I didn't want to take either. My heart sank as I realised the bottles held no solution for my predicament. Depressed, I lay in bed and masturbated slowly and regularly, the only way I could think.
After an hour or so, I got an idea. Maybe I couldn't stop what was happening to me but I could get my revenge on Julia. I figured she was doing this to control all of us. It was likely she wouldn't take any alterator herself, using them to enslave the others. So I decided to make a cocktail injection for her.
I mixed several bottles together, starting with the one intended for me. It seemed fitting to give that back to her. I had no idea what it would do to her but she was going to find out. I added some from the bottle 'girls', 'Stoner', and 'Boobies'. I had no idea what the last one did but I could imagine. Julia already had a nice set of breasts. I wondered what she would look like with much bigger ones?
The thought drove me into a masturbation frenzy. It took me thirty minutes to get control of myself enough to finish filling a syringe with my special cocktail. I hurried back across the island to her hut. Looking in, I found Julia asleep, naked in bed, an empty bottle of whisky in her hand. She was snoring heavily, dead to the world.
Cock in one hand and syringe in the other, I sneaked in, though I needn't have bothered; her snoring would have covered any noise. I pushed the needle into her bare ass and depressed the plunger, shoving the cocktail into her in seconds. She never even stirred. I stood up in exultation, masturbating over her oblivious form in silence.
After fifteen minutes, she rolled over and I grew afraid of getting caught so I hurried out to masturbate in the woods. I was so aroused by what I had done that I spurt a massive orgasm within less than thirty minutes. I hurried back to my hut and fell asleep.
The next several days were spent in endless masturbation. I kept fantasizing what was happening to Julia and it would drive my hand to my cock faster than the fluttering did. One morning, I was woken by the three guys, from Julia's camp, walking into my hut. I had a morning erection, of course, though it was almost down to five inches now, smaller than any of the guys' jutting cocks.
They grabbed me and pulled me from the hut to bring me before an enraged Julia. I noticed her breasts, puffy and enlarged. Her nipples were thick and swollen, erect enough to be visible through her bikini top. She wasn't wearing any bottoms and the reason why became immediately obvious. Her clit was swollen, much bigger than it should be. It was red and inflamed, throbbing and hard.
While I watched, she reached down and started rubbing it, uttering a heavy sigh of relief. Looking past her rubbing hands I noticed her inner thighs, coated with juices dripping from her vagina. She was very horny.
"Wipe that grin from your face, you bastard. It took me a couple of days to figure out what was going on. I was in such a fog and so damn horny. And my clit. It's growing and needs to be rubbed all the time. No way was that normal. It reminded me of you and that's when it clicked. I went looking for my Alterator kit and couldn't find it."
Darn! How could I have forgotten to return it? I was so stoned I couldn't think my way out of a paper bag. One of the guys came out with the kit, which had been on my bedside table. I hadn't even thought of hiding it.
"There's all the proof I need, you jerk."
She paused to rub herself some more, juices gushing down her thighs.
"Bastard. you couldn't leave well enough alone, could you? I wasn't planning to do any more to you but now, you asked for it. Hold him tight, guys."
They pulled on my arms until I could not move, my penis jutting rigidly in front of me. She ignored it focusing on my chest instead.
"This stuff was just intended for the girls. I hate them and wanted to see them with monster breasts. You, I just wanted to turn into a jerking pervert. Now, you're going to get something a little more obvious..."
She injected a large dose of alterator directly into one nipple, then again in the other.
"There. Try to explain that to your girlfriends when you get back home. Let him go and let's get out of here. We've got what we came for," she said, still rubbing her huge clit.
They left me standing there, my hand pumping slowly. I couldn't believe they hadn't hurt me physically.
