Hot wife fucks with her ex black boyfriend in missionary

When may wife and me met, she was still having a relationship with a black guy. They broke up some months later. Then she started a new relationship with me. She had told me that she used to wrap her legs aroun her ex boyfriend’s waist everytime they had sex in missionary. It turned me on a lot because I like female legs and feet. But when our sexual life together began, she usually kept her legs open! Just a few times she wrapped them before my asks.
After 10 years of marriage, we decid contact with her ex black boyfriend to get a trio (It’s a long story). Everytime they fucked in missionary she wrapped her legs around him!
