Spotted her brother jerking off to her panties and let him fuck her

Sister, is that you? You're screwed, I'm only talking about anal, no less

The guy thinks we're having phone sex, but no - it's anal with his brother

My sister sleeps without clothes, so my cock was in her anus

Tried jerking off to porn, but cumming in my sister's ass is much better

"You had a dick boyfriend, I'll fuck better!" — brother consoled his sister

"Sister, I've been watching some porn, why don't we try that?"
