Ho poca esperienza con il sesso anale, ma la mia sorellastra, da brava troia che è, mi permette di penetrare il culo!

One of my girlfriend's fantasies is to be able to have anal sex without pain and I'm somewhat overwhelmed because my penis is big... My aunt approaches me and we start talking about it, she says she has a lot of experience and can help me fulfill her fantasy to my girlfriend!
