My Girlfriend came on my friend’s cock during a threesome [MFM]

So this happened a few years ago and we're not together anymore, but to be honest, it's one of the hottest things I've experienced and I still kinda get off to it till this day (unashamedly).

Anyway, I was dating this girl Emily. Absolute smoke show and probably was punching above my weight a bit. If we put numbers to our looks I'm like a 6.5-7, and she's an easy 9 at least. I met her randomly at a fun event in the downtown area I live in and we just got along well. We were around 23-24 at the time, (I'm 28 now). So over a year goes by, things are good and kinda serious. Sex is great but I always felt like I was trying my very best to get her to cum and had to do magic with oral and my fingers to get her to cum. I could never make her cum with my dick and it was kind of disheartening but she always assured me it was just a mental thing for her.

Well, that wasn't true…. So one night her and I were having some cocktails and we were oddly horny, we started talking about fun and hot things we wanna do. We talked about role playing and scenarios and all that and then she randomly asked me if I'd ever want a threesome, either with another girl or a guy. I didn't want to just say "only with another girl" because I feel like that could get messy lol, so I said I think both are hot. Her eyes widened and she was surprised I'd be cool with another man. I really wasn't like crazy about the idea but also have the attitude of why not.

Anyway, shortly after that, she confessed she always wanted to have a threesome with two men. Long story short (I'll spare the details cause it'll take forever to explain), she admitted she had a small thing for my buddy Justin. Which wasn't surprising cause every girl I've met wants to fuck that man lol (he's just really hot and has his shit together).

So again, to skip the details, we devised a plan that ended up with us asking him to have a threesome a couple weeks later after a night out and some drinks. Knowing how hot my Emily was, of course he said yes (again, lots of more build up and details here but I want to get going to the good stuff).

Anyway we ended up at his place (logically it made more sense) and we got going. We started making out, her and I, then him and her. Then we started taking our clothes off and when Justin took his dick out, everything changed lol, she was enthused to say the least, in a way I haven't seen before. The man was hung in the best way, not monstrous but perfectly long and thick and just good looking. I lowkey got pretty jealous and I think it was obvious but I played it cool, meanwhile it was like Christmas for Emily and Justin had a cocky smirk on his face

She started off by giving me a blowjob whilst Justin went down on her. She came pretty quickly from that but like I said thats normal for her from getting oral. Then Justin and I swapped and I started fucking her from behind as she gave Justin head.

This is when I noticed things were not going the way I imagined because she could barely focus on my inside her. She was going nuts over Justin's cock, sucking and kissing and slapping it against her head. I was honestly annoyed but it also really turned me on somehow, to see my girl, a woman so hot, go crazy over a really nice dick; I just hated it was my good friend Justin and he knew

Ws swapped again and this time Justin started fucking her and it was a whole different experience from when I was inside her. He was hitting places she didn't know existed inside of her it looked like. After a while she had to stop sucking me off as she was about to cum, which again she never had from me fucking her so it was insane and hot to witness, so this was a first. She was extremely loud at this point as he kept nailing her….

Finally, she came so hard, but not only that she like fucking SQUIRTED all over his cock and was moaning his name…. She couldn't control it. She has never squirted before and I didn't even know that was possible for her, and neither did she from what I heard later. At this point I had already came from seeing this and was honestly really upset so I told her let's go and rushed her out to get changed. She was pretty pissed at me for ruining the moment. I'll admit I acted like a complete baby which probably made me look like a bitch in her eyes.

Justin and I got in a texting argument after and he was talking shit saying stuff like "it's not my fault you can't make your girl cum". We kinda stopped being friends for a while after. Long story short, two months later Emily broke up with me. She gave some sorry excuse about wanting to focus on herself but I know for a fact it was about the sex because Justin started fucking her non-stop after we broke up.

He and I made up and we're cool now, and I Lowkey still find it so hot and he'll tease me about it. This definitely shaped some "submissive" tendencies I have now, even some light "cuck" fantasies as I still get off to what happened and feel shame over it.

Anyhow, it was one of the hottest and most intense things I've seen, I've never seen a girl be so primal in sex, and it was so hot that SHE was a smokeshow that I somehow couldn't unlock that part of her. Listen guys, size isn't everything, but it definitely fucking matters (especially if you're small small), don't let the girls tell you any different ;)
