Going clubbing

"We're hitting the town tonight, Julie. As soon as I'm done with you, I want you to go put on something nice and shiny. Pink, glitter, latex...slut it up, okay?" you command, to which she responds with a moan and a nod, her eyes still closed as you press her against the wall. "When you're dressed, tell Mom to do the same. I'm guessing she doesn't have too much maternity wear that's fit for clubbing, but I'm sure she can make something work."

"Ahh...okay, John..." she manages to reply. Moments later she's climaxing, her pussy tightening around you as she shakes with orgasm. Still a little daunted by the **** factor, you attempt to pull out before you unload inside your sister. After all, you got your own mother pregnant, so shouldn't you be careful? She tightens further, however, holding your cock inside as she grinds against you. "I'm gonna dress up for you," she continues, glancing over her shoulder with a sly grin. "You're gonna be so busy looking at me, you won't even look at other women...not Mom, not anybody. She shouldn't even try, because I'm gonna beat her." She punctuates her words by bracing against the wall and thrusting out her ass, burying you to the hilt.

Her wild enthusiasm is too much to bear, and before you realize what's happening, you're shooting thick ropes of cum deep inside her. You hold her tightly, pressing your tip in as far as it will go. You can feel her every twitch and tremor as your cum coats her insides.

"Mmm, fuck, John...if I didn't know better, I'd say you were trying to knock me up," she says with a giggle.
