Got lightly cucked on accident?

My ex GF and my college roommate were both pretty horny characters so it wasn't uncommon to have conversations take a sexual turn when hanging out together. It was always lighthearted and never actually led anywhere. Until...

One night we were all crammed together, sort of cuddling on this pillow fort situation as we watched a movie. It was me on one end, then my GF, then my roommate, then his GF was also there on the other end.

At some point my roommate was massaging his GF so I figured I'd treat my GF to the same. We were all kind of on our sides so we could still see the TV (though I don't think anyone was watching too much at this point). My GF was wearing a loose comfy sweater with no bra on underneath so I was massaging under the sweater, sort of lifting it up. I'd reach around and squeeze her boobs every so often briefly exposing them when I did, just to be silly. No one could see because my roommate's back was to her, but perhaps my GF took it as a sign to push some boundaries because soon after, she started massaging my roommate. Now we were all in a massage train.

After some light group conversation, my GF said we should switch sides. There was some scootching and now we were facing the other way, all pretty much spooning each other now - my GF spooning me and my roommate spooning my GF. There was massaging going on still, but it wasn't reserved to just the back anymore. My GF would run her hand down my side, squeeze my butt, and run back up to my chest. I could tell she was a bit turned on by this situation. I could also feel another hand that was not hers sneaking around to her front side. Their hands started moving in sync, as if my GF was relaying to me on my body where my roommate's hand was touching her on her body.

She was massaging my side and then worked her way down to my hip. I adjusted and peeked over my shoulder and sure enough, his hand was quite low of my GF's hip. My GF rolled her hand over and now massaged deep into my butt, her fingers wrapping down to my inner thigh. Surely not, I thought. But I didn't say anything. She massaged my thigh for a minute and then worked her hand back to my stomach towards my chest. At this point I could feel my roommate's hand too since it was also against my back. The hands both worked their way to our chests and that confirmed it. My roommate was getting a handful of my GF's breasts right behind me.

I didn't know what to think. I had never experienced anything like this before. Sure, my GF and I would fool around with my roommate in the vicinity sometimes - she'd flash me when she was behind him or I'd sneakily rub over her vulva under the blanket when he was in the room - but it never actually involved him. Now he's suddenly massaging her tits and feeling up her ass. I can feel her wiggling her butt too - the way girls do when spooning you to rub against your crotch. As I'm thinking about all of this and how I feel about it, my GF's hand goes down and runs right over my cock, pressing firmly down as it comes back up, and I knew what that meant.

I panicked and yelled "flip!". I wasn't not into it, but I also didn't know what to do - I just wanted to hit pause. However, this didn't stop things... at this point my roommate was making out with his girlfriend on one side while he had his hand behind him on the other side just straight up rubbing my GF's pussy through her leggings. All while I just watched from behind. Part of me wanted to keep this going and join in, but unfortunately I did not find my roommate's GF attractive at all, and if this turned into group sex I felt like I'd be kind of obligated to engage with her. Needless to say, I was not as into it as they all were, so I kind of killed the vibe after a bit.

I was so turned on and also felt so awkward at the same time. If it was just my GF and my roommate I would have for sure had a threesome with them, but of course I had to be all awkward because his GF was there. I think about this a lot. It is still hot to wonder what could have been if I wasn't such a dweeb.
