I [M] caught my G[F] getting fucked on the couch

Bit of background, been with my GF since we were both 17 so hadn’t been with anyone else apart from each other before. But 5 years into the relationship and I started getting attention from another girl and eventually got a few hand jobs and blowjobs before fucking her fully.

Cheating on my girl then happened on the regular for about 9 months before I started to float the idea that we bring a third person into the bedroom with my girl and me. Even suggesting we get her another cock to play with or I watch her getting fucked. She even agreed to a threesome with another girl but it didn’t come to anything.

So fast forward a year or so later, I’ve stopped fucking this other girl. My gf is on a night out on the town with a few of her extended family, while I’m at home. Her cousin brings his wife along to it who also gets her brother to come drink with them to. This guy is a good bit older than us, like early 40s, keeps in pretty good shape, very confident, can tell he just fucks women regularly and just leaves them when he’s had enough. Seemingly they hit it off really well and she starts to get more secretive and distant, not answering calls or texts as quickly when we’re not together, not being as available as much as she once was.

About a month passes from that night out she had. She’s off for the day (she’s a nurse) and I’m at work at my 9-to-5. I get off a little early cos I had an appointment to go to and get told just to take the rest of the day off when it’s done. So I head home. When I walk in the door, I hear a lot of noise coming from the sitting room, bit weirded out by it, so I wonder what’s going on. I don’t even take my coat off and hang it up as I normally would right away when I come in from work.

First thing I see when I open the door to the sitting room is my gf on the couch facing the door and someone behind her fucking her. I stood there in silence just looking at the scene in front of me. She tries to stop and apologise and is pretty panicked about it, but he’s not stopping at all. This guy kept on fucking her, probably harder and slower now that I had walked in and caught her. The guy was a good 15+ years older than us and I could tell he’s probably done this before with couples in their mid 20s. After standing there for a minute or two, I move and sit down on the armchair and look at them both. Seeing this, my girl relaxes, giggles and starts to enjoy herself again. Maybe even more. We had discussed this type of thing like a year before but she was pretty reluctant to do it. Now she was doing it for real.

As they got back into it, I relaxed in and watched, taking my own clothes off and showing them how hard my dick was watching my beautiful girl get fucked in front of me. Stroking as I watched, the guy fucked her harder and harder before eventually cumming inside my girl’s pussy. Once he was finished, he pulled out and I saw how huge he was. It was a couple of seconds before I saw that she didn’t make him wear a condom. He had just nutted in my girl bareback. I was mesmerized by his cock and how big it was, a good 2-3 inches on me and I’m like 7.5″. As she settled down, she looked at me still wanking my cock. I got up from the seat, walked over to her bent over body, and ate her cheating pussy and ass before sticking my cock in her and fucking her myself. The guy was still in the room and watching as I pushed his cum further into her. It only took a couple minutes before I was adding my cum to his.

The guy got dressed and made his way out, then we sat and discussed what had happened. Turns out she didn’t mean to get caught but had fucked him once or twice a week for that month and wasn’t expecting me home. I said I didn’t expect that to be as hot as it was.
