Because he wasn't jerking off, so he got his sister while the girl was away

Brother, while you're playing on the Xbox, I've already fucked all your friends

Brother, you haven't been shy for long — you saw boobs and you're ready to fmf right away

Brother urges sister to be modest, but she just wants to fuck

Don't jerk off to yourself, sis, and wait for me. I'll finish it off again

I was fucked in 3 positions to 3 orgasms 🫶🏻 Brother, you're the best

"Sister, how many times do I have to tell you to knock? I'm jerking off."

Blowjobs don't make you come, bro, but fucking you and you had four orgasms

How's that, sister? My dick is good enough to stick in you

Sister, don't let me stop you from watching TV, or I'll snap and fuck you like a bitch

She put a condom on her brother's dick and gave her round ass

Bro, how about this: you touch my boobs, but don't tell your mom about porn?

You don't want to suck your brother's dick? Then I'll tell my mom everything I know

The only dick in the house is my brother's, so I'll have to jerk off by myself

Fuck, my sister just asked for a massage, how did I end up under her?

I didn't want to go to college so much that I agreed to have sex with my brother

Brother, you're going away without me for two weeks? Who's going to suck your dick?

My sister spotted me aiming at her ass and bitch-slapped her mouth

Without a condom, I only put it in my pussy, judging by my anus, I get fucked in my ass

Her boyfriend doesn't want to suck her dick, but she gives her brother a pussy

Don't take that sex toy, brother, or who else is going to fuck me?

I won't let my sister's chubby ass go without a dick

I complained to my brother, and he consoled me as best he could — with his dick, of course!

Sister got hungry before going to bed — I had to feed her sperm
