How do you say no to a sister who says she wants to fuck?

I want to fuck, I want orgasms, and I'm willing to have sex with my brother

I'll fuck this one and give it to the other, and I'll cum on both of them. Let them share their cum

Okay, brother, I'll let you cum in my panties, but this is the last time

What can a slutty sister give her brother? — A blowjob, of course!

Holy shit, you came twice! That's what I call missing your sister

Oops, my sister's prank has gone too far and she's demanding my dick... I don't mind

My brother won't let me play on PS4, I had to tempt him again

I'm gonna fuck her to three orgasms myself so my sister doesn't give it to anyone else

Why the fuck did you fuck the bed? 🤔 I'll suck you off, you cum in your mouth and get it out

I already fucked my sister in her tight pussy, now I want to fuck her in her tight ass too

Friend girl fucks her brother, that's not right. Let him fuck me, we're friends

So horny at school that she ran to the guy for sex

She's trying to have sex again. So I fucked her, my sister's a whore

It's never happened before and here it is again! She's stuck and I have to fuck her 🤨

Sister, are you sure you wash yourself? Let me help, my parents aren't home
