You'd rather go find Megan

You're not really in the mood, well for Amy right now, despite your painfully raging hardon. You'd rather taste a luscious piece of your step-sister's pussy, and you know just where to get it.

Breaking the stare with Amy, you say "Don't you go anywhere baby, I've got some exercises for us to do when I get back. Just gotta run to the bathroom before we get started."

She giggles, "Should I do some warm up stretches?" running the back of her hand down her sweaty glistening stomach and down over the spandex fabric covering her pussy.

Grabbing a towel to cover your nakedness as you walk out the door, "Yeah, I wouldn't want you to pull a muscle or anything."

You smile to yourself as you strut down the hallway, with a swagger in your step knowing that you are the hottest thing since sliced bread to hit this campus, and you are taking it by storm.

You fling the swinging door to the bathroom open hard, walking in with complete confidence. You can clearly make out the sounds of shower water jetting out onto the floor, and the faint subtle moans of a female.

You figure your step-sister is clicking away at her pussy dreaming about massive cock giving it to her. Your cock twitches at the anticipation of her excitement that will come from you valiantly entering the shower with her and giving her what you know she wants.

With unmatched confidence, you pull the shower curtain open, dropping your towel to the floor. But instead of finding your step-sister drilling away at her pussy, your mouth drops to the floor as you stare dumbfounded as some heavy jock, with a tiny cock, fucks your step-sister from behind. They don't notice you at first, and you continue to stare in amazement as your cock deflates disgustedly. Your sister's eyes catch you and she says, "Oh hey bro, how's it hanging" and giggles.

What's the jocks reaction? Do you stick around to find out?
