You're super-strong and super-horny.

As your course-mate and his supervisor circle around you cautiously, you begin to test your new body. You flex your biceps and smile with delight as your new muscles tense and grow. You can't wait to get out somewhere and test just how strong, how fast, how tough you are.

There's a level of your consciousness that isn't taking this whole thing as well. The scientist in you is voicing the same fears as Tom and Rick, that the change is too much and completely unprecedented. How did your whole body grow so much? Are your bones strong enough? Is this temporary, or will you be stuck like this. And on yet another level you know there are other problems too. How can you possibly explain this change to your friends? How can you continue to live a normal life even?!

But all of these doubts and fears are being pushed down and silenced by the pounding of your massive new heart and the adrenaline surging through you. Naked, you take two cautious steps (remembering the new balance of your super-human form) and lift a heavy rack of medical equipment as if it were an empty cardboard box. Your muscles bulge, but it feels like nothing, and you're sure you can lift much heavier things than that.

"Holly! Jesus, calm down!" Rick bravely takes a step towards you, holding his hands out as if placating a wild beast. "In this state, we have no idea how much stress your body can take! We need to be very cautious!" You look down on him with no little scorn. He may feel the need to be cautious, but you just want to see how much you can do.

The lab is starting to feel hotter and hotter, you notice. For a split second you wonder if it's just you, but then you smell the two men in the room with you, and see the sweat beading on their brows. Maybe your change created a lot of heat as a by-product? Or maybe it's something else. With your heightened senses you can certainly smell something mixed in with the chemicals and sweat in the room... What is that?

You look down at the two great breasts that you carry now, and see that perspiration is starting to break out on your own body now. You bring your hands up without thinking, to wipe at the sweat, but straight away you're cupping your massive melons and squeezing them, reveling in how soft yet firm they are.

"H-Hol?"

You ignore Rick and keep massaging your swollen tits. They feel amazing to touch, and incredible on your body, far more sensitive than your breasts used to be. Your pulse is rising, you note, and so is the temperature in the room as a whole. You cup, lift, and squeeze them - then start to rub your thumbs over your big, dark nipples.

"Uuuhhn!" They're so sensitive! The moan of pleasure spills out, loud and impossible to hide. As you and all the scientists watch, the two circles of your nipples visibly harden and perk up. You can't resist pinching them, and as you do, jolts of pleasure start to shake you. Fuck! This body is amazing! Everything feels so good, amplified vastly from how it used to feel.

But your brain isn't used to the pleasure, and you're not used to standing in this body yet. Groping your tits, you sway then slowly drop to your knees. And then your big right hand slides quickly over your sweat-covered, muscular torso, over your new, curlier bush and between your massive, mighty thighs.

You're lost, forgetting totally that you're pleasuring yourself in front of five scientists, and just losing yourself in the feeling. Your new, luscious pussy is soft, hot and literally dripping with your juices. Your two, thick middle fingers sink immediately into that heavenly hole and you cry out in ecstasy. "Aaah!" You start to finger fuck yourself, kneeling back on your heels and letting your head and your long hair fall back, while your vast chest heaves and jiggles as you gasp in pleasure. Your greedy pussy slurps and drools obscenely as your big digits plunge in and out, again and again. You feel your juices trickling down your thighs, dripping from your cunt onto the cold plastic floor of the lab.

It's incredible. You've never felt this good, and as one hand squeezes one massive tit and the other continues to frig that sloppy cunt good and hard, you thank God you had the chance to take this ****.

"What do we do?" You hear a woman's voice ask. Alice it must be, the only girl who'd been down here. But there's no reply and, controlling yourself enough to slow your diving, driving fingers and open your eyes, you see why.

All four guys present are staring at you slack jawed, transfixed. You still can't see the two guys in the separate observation room too well, but Tom and Rick are clearly sporting massive hard-ons in their sterile lab-pants. Just from looking at you? Or is it something else, some kind of super-pheromone you're giving off?

The new, feral **** in you growls hungrily. Hot, hard cocks. Mmmmm...
