Friend girl, you weren't lying-- your boyfriend's dick does fit in your anus

Yeah, I was bugging my sister, but I didn't know I could fuck her in the ass

Why don't you stick that dick in my anus, and I bet it goes all the way in

Ouch, it's my ass! How can I tell a guy why it hurts there?

Be honest, you wanted anal, not a massage, so I put it in

She wanted to have an anal orgasm, so he started fucking her in the ass
