Something about the idea of touching Cory's ass just didn't sit right with you, so you take off running to the door. You fell behind the other survivors, but hopefully not too far-
As you fling open the doors; an eruption of fresh pink smoke bellows into the gym. You look down to see your clothes are now nothing more than a lacy bra and panties, and you feel your member screaming for attention underneath. You can't help but indulge it; the fabric of your new undergarments feels too good. Your nipples tense up as they push forward to fill out the bra, and you start to grope yourself with your other hand. It all happened so fast, but soon you find yourself looking back at Cory; maybe you can take her back up on her offer...
"Yeah I got a deal for you" She says kinda upset about how you just tried to ditch her. She slaps you so hard you fall over onto the ground. As you try to pick yourself back up, you feel Cory's dick slide into your butt. "how about this new deal?" she says with confidence as she rides you.
With Cory railing you in the butt, you reach down to try and finish yourself off; only to discover that your panties have changed into a chastity cage! But before you can manage to exclaim anything, Cory pulls out of your butt, grabs your head, and throws your mouth over her cock just as she cums. You swallow every drop, and you see a key now on Cory's neck.
