When I married Paul, i was 39 and he was 48, great guy, we really loved each other, still do. I was a single mom, with an older daughter, he was recently divorced with a son in college.
Paul's best friend Mark wasn't always around but we would get together with him and other friends fairly often. He was always flirting and I'd catch him looking at my legs quite a bit. But it wasn't until my 40th birthday that he made a move. Paul threw a party at the house with several friends and family. Great party, I got my hair done, brand new dress, heels, etc. Throughout the party I would notice mark's glances at me, but instead of looking away when I noticed, he just stared intently. I had no interest in Mark other than it felt flattering that he was noticing me. At the end of the night when most of the guests had left, I was in the kitchen, alone getting a glass of water when Mark came in to tell me he was leaving, and came in for a hug which wasn't unusual, however this time, his hand went straight to my ass and he gave me a kiss, fairly quick but slipped me some tongue.
I pulled away and said "what was that?"
He just smiled and said happy birthday. At that point, Paul walked in to tell me my sister was leaving and told Mark he was going to be away from work the next week, so he'd talk to him when he got back. After he said that, I looked over at Mark who just looked at me and smiled.
The next 2 nights after the party, Paul and I made love, I think I may have been compensating for the guilt of how I felt about things with Mark. When Paul left for his trip on that Tuesday morning, I gave him a nice kiss goodbye and sat and had my coffee. Not an hour after he left, my doorbell rang, it was Mark. He said he knew Paul was leaving and wanted to check in with me. I was shocked, I had no makeup on and just a bathrobe. I wasn't sure what to do so I just invited him in and offered him coffee.I said I was sorry for how I looked but wasn't expecting anyone. he just laughed, then said I should go shower and make myself up for him, then come back down and stay in just my robe.
I laughed and said, "Yeah, sure I'll get right on that."
He didn't laugh, he just said, he'll wait.
