I (m38) met my fiancé (f30) through tinder around 4 years ago and one day I got the feeling she blowing me off because she was meeting up with another guy. I decided to throw my intuition - and kinks - on the table and see where it ended up. I asked if she was going to see another guy. She was a little defensive at first but admitted she was. She apologized and said she understands if I don't want to keep seeing her. What I said next stunned her. I asked that if she was having him over to her house, would she be grossed out if I hid in her spare room and listened? "Really!?" she replied. Followed by "That's kind of weird". I assured her I wont be jumping out of a closet in the nude yelling SURPRISE or anything like that. She admitted that it sounds and feels weird but she's strangely not turned off by it.

After a few questions and time to let it sink in she agreed and we organized for me to arrive early and park nearby. We sat on the couch and she asked again if this is really something I'm in to and before we could get too far into the conversation she got a message from her date saying he was just pulling up. She rushed me to the spare room and told me to lock the door. My anticipation at this point was at an all time high. I could hear them chatting and having a glass of wine on the couch. I could hear them going quiet and was sure they were making out. Next I heard two sets of footsteps heading towards the master bedroom and was as hard as I had ever been in my life. I couldn't hear much at first but it didn't take long before I could hear her moans and their bodies slapping together. They went for what felt like hours while I just listened from the spare bed, getting myself off over and over again.

When they were done, she saw him out and came straight to see how I was. I think the hard dick in my hand and the smile on my face told her all she needed to know. She was covered in sweat and only wearing a bath robe. Awkwardly, she said "what now?" and I threw her on the bed and ripped the robe off. She tried to stop me and asked if she should have a shower first? I pushed her legs open and started licking her freshly fucked pussy.

We fucked until exhaustion and collapsed in a heap. After catching her breath, she looked at me and said "I've never done anything like that in my life. I thought this was going to end badly. Can we do it again?"
