It's not incest. We're step-siblings. It's just creampie and sex

She let me touch her breasts, and I got carried away and came in my sister

Why didn't I give my stepson a bigger dick and more cunnilingus?

Yeah, I'm not your mother! But on the plus side, you can fuck me and lick me

Stop staring at boobs, bro - when are you gonna start staring at me?

Hey, why are you jerking off alone? Don't you want to fuck your sister?

He says, "Don't!" but he's got a boner, so let me give you a blowjob, bro

I'll cover my sister's mouth before daddy wakes up and sees us fucking

You're a sex addict, and so am I - fuck me, bro, we're alike in that way
