Father

Your step bro stopped pounding you, he looked worried, you'd never seen him look worried before, he wasn't always so brash and confident, frozen, his thick cock still deep inside you. It left you a little time to breathe, thought the pressure of that beast forcing open your soaking pussy was still immense, but enough to reply,

"I'm, fine.." You called back, holding back a short moan.

"Yeah you are!" He laughed, "I know what ya doin in there slut!"
"You, uh fuck, do?"
"You getting off thinking of my dick!" You heard a chuckle, and then, he burst through the door. "You just gotta a..."
He stopped talking, and looked over the situation in front of him. He locked eyes with his son.

And then, he smiled. "Good boy!" He seemed elated, "I knew you had it in ya!" he couldn't hide his glee on walking in on his son fucking you.

Then he turned to you, "Fucking slut loves that black dick, don't ya?"

You felt embarrassed, your face flushed red, "Yes..."You sighed, you couldn't really deny it, whether it was your choice or not, you had had several really enjoyable experiences with it, fuck, you'd even used your new body and persona to get it yourself, in a way, you were enjoying it.

And then you started thinking about his, you looked down at you step fathers crotch, and bit your lip. You could get him to join maybe? He probably wouldn't say no, but that would be making the risk biggerm you already had one in your pussy, waiting to finish.
