You’re Growing! Do something! Shrinking in excitement chapter 15 by copier · original author: darthkitten

Panic sets in more! Jessica isn’t able to move, meaning your trapped! Your erection you may have once had is no more! Sounds of the girls coming back from the showers distracts you for a second, you couldn’t possibly risk getting caught now. Your only hope of coming out of this undetected is to shrink down! Looking behind you, a mirror previously unseen allowed you a view of your sisters bound form. She was gagging on whatever was shoved into her mouth to muffle her, and she was desperately looking between you, and through the slats in the top of the locker.

Something tickled the top of your head, and looking up, you could see the lips directly above you. Jessica squirmed more when you tickled her, a new look of panic is painted on her face and looked at you figure something else out. Another inch. Your face pressed right up against her lips, and you spat in embarrassment and tried to move your head away, only for her thigh to push it back in place as she let out a soft moan. Looking up at her through the mirror, you gave an apologetic look to her.

“Im sorry, but I have no other choice” you said quietly, and began to stroke your softened penis in hopes of getting it hard, on full display for her watch in the mirror. Her face turned even more read if it was possible. The small space was not helping you achieve your goal… another inch.

Your face was forced between her lips, your chin rubbing against some small fleshy button between her lips, which another small moan escaped her gag. You tried to yell out, but muffled against her flesh, it did nothing. Stroking harder was barely making you get hard. This was a worst case scenario and your brain was in full out crisis mode. Voices were heard on the other side of the locker door as Stacey’s locker opened.

“Hey, have you seen my panties I used for gym? I cant find them anywhere.” Stacey asked. The dots were slowly coming together in your mind.

“Maybe someone snuck in here. That’s why you got to keep your locker locked Stacey!” Bethany said in a mock tone

“Ewwww!” a few of the other girls said

“Say you found them in your bag, I have plans with them” You hear Bethany whisper next to the locker

“False alarm!” Stacey said, and you couldn’t see it, but her face was bright red.

“Stroke… Stroke… Stroke…. C’mon! The one time I actually want to shrink!” You thought frustrated with yourself. Every ounce of your body fought to get excited, and it was working, but not as fast as the panic enduced growth was. Another inch.

You felt your face slowly pressing into her more. It began pushing an inner ring open, your nose filled with the smell of sex and juices tried to run up your nose, but leaked down the sides of your face. A moan erupted from Jessica. Another inch, and another… Slowly but surely, your face was being forced inside her. You could taste her juices as she squirmed above you, an involuntary response from her body to its most recent intruder. One more inch… Your chin forced its way inside after your face, her lips grabbing behind your jaw, trying to pull you in more.

The flexing walls of her pussy sucked at your face, covering them in juices that you dared not to taste on purpose. You couldn’t breathe. You tried to shift your head downwards to get your mouth out, to no avail. You were beating yourself furiously. And if you could see outside to your sisters body and not your own peril, you could see her body reflexively move slowly up and down, her eyes leaking with tears of embarassment. Your head was probably 3 inches wide at the moment, bigger than anything she has ever experienced or seen.

Another inch. Your head reaches its widest point and is sucked in as her knees give in, forcing your entire head inside as she buckles against either side of the locker, no more room given. Her normal clothes that were knocked down onto the floor by both of your feet. Everyone had left by now, dressed and ready to leave for practice or home. The two of you alone in this sick predicament. Her muffled moans could probably now be heard if you walked into the locker room since there were no other noise to cover it.

She shudders over your head. You’ve reached the equilibrium between shrinking and growing as you beat more, causing you to slowly shrink, and the danger of drowning in your own sister causes you to grow causing your head to “pulse” within her. A few minutes go by, your vision beginning to fade and her moans get quicker and louder.

With one last stroke, you let out a torrent of cum infront of you and at the same time her walls become rock hard, and a loud squell that could probably be heard outside of the locker room her walls force you out as she orgasms, soaking your head and body as she does in juices.

Both of you breathe heavily as your body shrinks down to 1 inch, and eventually when you get energy to, you crawl out of the locker, gladly nobody has come to investigate as your met with an empty locker room. A minute later after the aftermath, you slowly reach the height to reach her combination lock. You couldn’t ask her what it was, so you search your brain for her combination, you try the only thing that can come to mind and….
