Boyfriend's Reaction

"Hey bro, how bout a little privacy here, can't you see I'm deep in the middle of something." The jock says.

To you it doesn't look like he can be deep into anything at all with the tiny ass cock he's packing. But you hold you tongue and don't bring that to attention just yet.

"Josh this is my step-brother, bro this is Josh my boyfriend" Megan says, obviously faking her moans as he continues to piston in and out of her. You just give Josh the head nod and begin to turn away to leave in disgust.

"Where are you going?" she says, moving herself away from Josh's cock momentarily. "I thought after Josh got finished with me you could finish me off." giving you the pouty face that used to always get her her way when you were kids.

Josh isn't very pleased with her comments at all, "What the fuck, you mean you two," squinting trying to take it all in, "you're telling me you guys," looking disgusting, "man that's just fucking sick!" grabbing his towel and and brushing past
you on his way out of the shower, still mumbling obscenties to himself and shaking his head as he walks away and leaves the bathroom.

Now it's just you and Megan in the shower, both completely naked, both aroused. You know she wants you to finish her off, but you are slightly upset that your sister was banging some guy in the shower when you thought (even though it seems kind
of obvious to you now that there would of course be someone else) that you were the only one. Then it hits you like a ton of bricks, the stranger in the bed with you two last night could have been Josh! Damn! Good thing you didn't try and make
a move.

So do you give your step-sister what you know she wants or do sis have some explaining to do?
