I was having an affair with a co-worker who was a married, much (18 years) younger woman. During our first hotel visit while licking her sweet pussy, I paused to bite her inner thigh hard to mark her (I was being considerate in putting this first one somewhere she could hide it). She told me later she had an instinct to object but knew it was my right to mark her. While we were taking a break between sessions, she said, “That is definitely going to leave a mark.” (She wasn’t objecting, she was just pointing it out.) I said, “That’s exactly the point. You belong to me now and that mark is a sign of that.” She smiled shyly and wiggled a little bit.
