When he was single we liked to fool around with each other and he always said that I had the nicest ass he even seen but I never let him fuck me in the ass. My brother is really a nice guy and the moment he started dating his wife, he told me we needed to stop our sexual experiments because he didn't want to cheat on his girlfriend/wife. This lasted until a couple of months ago when he found out his wife was cheating on him. He told me about it, and I asked him if still liked my ass and if still wanted to try it. Since then, he's been using it a lot and I love it.
