I doubted whether I could fuck my sister, but she left no choice

Stop it, you're crazy, don't touch your brother's dick!

Shit, brother, you're my skirt, what am I going to tell my mom now?

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

If my brother likes a blowjob, it's fine for a guy, too. I checked!

"Get out of here and don't touch my dick — you're my sister!"
