Sorry, this is a bit long but a very true story...I finally came out as gay 2 years after I got divorced. Over the past few months I have been hooking up with a guy that I have known for several yeras (since middle school) like 2-3 times a week. We are not boyfriends orcsnything...more like just fuck buddies...Anyway, one Friday night, me (44) and the guy (41 - we'll call him Mike) were fucking....Mike was on all 4s facing the bedroom door and I was pounding him from behind when my son (we'll call him Ed) suddenly walked in on us....freaked out, I tried to fold over Mike's back to hide the nakedness trying to grab a pillow but Mike just kept fucking himself with my cock, moaning while my son stood there stariang at us for what seemed like forever but was probably bout 30-45 seconds or so. After Ed walked out, Mike just kept talking about how hot it was and flipped me on my back and rode me till we both came. Afterward as we laid there, Mike just kept talking about how much it turned him on that my son walked in on us and stuff and I just thought he was just talking in the heat of the moment....The next morning we fucked again and I finally decided to get up and hop in the shower. When I came out, I noticed that Mike wasn't in bed anymore so I got dressed and headed downstairs thinking Mike was having coffee or whatever. Halfway down the stairs I noticed 2 guys on the couch and realized it was Mike and my son...my son was sitting on Mike's lap and they were making out, like really making out. I froze for a few seconds and watching them kinda turned me on. I quietly back up like 2 steps so I'm out of view and called out "hey mike, did you have any plans today?" By the time I get down the stairs, my son is walking in my direction, he's in a white t shirt and sleep pants, trying to hide his boner and Mike is on the couch in just boxers with his legs crossed trying to hide his boner. I casually walk over to the kitchen, set my phone down and once I saw my son was already upstairs, I walk over to Mike and said "looks like y'all both really into it." and he tried playing dumb and I don't know if I said it in an angry tone or what but I told him "why don't you just go up and finish what you started?" Mike gets up and says "quit being such an asshole" and starts apologizing, saying he is sorry, he didni't mean for anything to happen. He keeps trying to apologize and I tell him to keep his voice down, we can go discuss it upstairs. We head up stairs and right as we're coming up to the door of my son's room I grab Mike, knock on my son's door, open it an tell him, "you have company". Mike just stands there and I nudge at him like 3 time to go in but he doesn't do anything so I said you have 5 seconds before I change my mind and nudged him a little harder til he finally goes in. I just say "have fun" and shut the door. I pretended to walk away but stood at the door trying to see what I could hear. After several minutes, i didn't hear a peep so I went back to my bedroom thinking Mike chickened out, he will be out soon....several more minutes passed and they were both still in the room so I sneak back over and as I come up to the door I hear Mike hiss and moan and vaguely hear him whisper "yeah" everynow and then...I'm thinking, of fuck, he's getting his dick sucked...now I'm really turned on....I'm literally shaking...I don't know how long I'd been standing there but then I hear quite a bit of movement, some whispering (couldn't really tell what mike was saying) then everything seems silent for quite a while til I hear my son screech and I hear Mike tell him "no, don't. It'll stop hurting just leave it in" Hearing my son moan like that was an experience I will never forget....i managed to slip my phone under the door and record a bit of audio....It didn't take long for me to cum.....anyway, I hear Mike cum so I run to my bedroom and a few minutes later, Mike walks out of my son's room, still semi hard, and into my bedroom to the restroom. He has the biggest smile on his face..it was an embarassed, happy kind of smile..like the kind of smile you get when your brother embarasses you by teasing you about your first girlfriend or something....While Mike is in the shower, I walk by my kid's room and see him just staring up at the cieling....almost like he was replaying the whole incident in his head....after that nothing was ever discussed but Mike still comes over and spends most nights in my son's room....after like the 3rd time I did ask him how it all started and Mike confessed that day was not the first time they had messed around....Mike admitted that over the 2 weeks prior to that they had made out and had oral sex like 6 or 7 times. Mike told me my son had been asking to go further after like their second encounter. He said that day was the first time they had ever gone all the way. Honrstly, getting cucked by them totally turns me on.
