Шурин кончает в горячую сестру жены, чтобы вернуться на неверную шлюшку

I went into my brother-in-law's room to see if my sister was home. I wanted to see if she wanted to go out and have some fun. He was already under the impression I was going out with her tonight. We had no plans. He was so upset that his suspicions of her cheating were correct. He said he wanted to get back at her, so I fucked him until he came inside of me. Sweet revenge!
