"Ugh I still feel weird..." you hear the figure in front of you saying. They look good at least.
The person reaches down and extends their hand, "like, maybe you can still help man", you absentmindedly reach out and grab it; pulling you to your feet. It's Cory still, you're glad you could help them, still help them, but you tell 'em that you could use a minute on the bench first. "oh good idea", Cory leads you to it, but instead of sitting on it, you just kinda flop over onto it like a wet towel.
From your new upside-down vantage point, you see Cory position themselves behind you with their large, erect dick. Something inside you says you should get out of here, but you're just feeling too drained to care. You feel Cory's member slide into your virgin anus, it feels weird; like you're dropping a deuce but it's moving the other way, then they pull back, and push back in again, and again, and again. With each push into your butt, you feel it getting softer; you don't care though, you never felt anything like this before. Tilting your head down, you notice your legs seem thicker than before, and the collar on your gym shirt begins to expand. As you begin to see your nipples, you suddenly have an urge to pinch one; As you do, it feels like electricity going off inside you.
Everything begins to feel floaty, then you hear someone behind you saying "here I cum!" and you feel it. Cory's dick unloads into your butt, and you begin to feel something washing across you from the inside. You feel the strange force make it's way to your chest, your nipples puff out again, and burst out into a pair of boobs that fill out your dress nicely.
You roll off the side of the bench and pass out on the floor.
