Girlfriends gay friend (29) came on my ass and has me (28) doubting myself

Recently went out drinking with my girlfriend and her friends, one of whom is a gay guy that recently got out of a rough breakup. We all had a fun time, lots of drinks and dancing. Eventually the night came to an end and the three of us went back to his place. My girlfriend was way too drunk and passed out in his guest room. Meanwhile, me and him sat down on his couch in the living room. We had a couple more shots, while chatting and watching TV.

He began talking about how pent up he had been since his breakup. That he hadn't gotten any release in weeks. I don't know why I told him but I also confided that my girlfriend and I had been pretty dry lately too. I noticed him rubbing a bulge in his pants, but didn't pay any mind to it. Eventually he asked if I wanted to watch some porn and jack off together. I don't know if it was the alcohol, or being pent up or both, but I said sure. He pulled up some porn on his phone and propped it up between us scooting a little closer to me.

We both pulled out our dicks and started stroking, and I couldn't help but notice how much bigger his dick was than mine, almost twice the size of mine in length and girth. As I got hornier and the alcohol started to hit more, I noticed myself glancing at his thick cock more and more as he pumped it. Before long I was watching his dick more than I was the porn on the screen. We made eye contact and he just gave me a devious grin, shaking his big dick around a bit. He asked if he could put on some gay porn, saying he wouldn't be able to get off to straight porn. I said sure why not and so he put on a scene that seemed intentionally specific. A hung white twink fucking an asian jock.

Now he really started pumping his dick, moaning as he watched the video. I was barely even paying attention to the porn at this point, fully entranced by his dick as I stroked my penis. I felt a warm sensation building up in me and told him I was close to finishing. He told me he usually can't cum to porn and needed something else. He asked if he could look at my ass while he jacks off. I was nervous at first, but between the alcohol and being so worked up I said sure.

He had me get naked and get on all fours on his couch as he stood up behind me and began stroking. I watched the porn on the phone, realizing how similar of a position I was in compared to the scene. A horny asian jock on all fours with a hung white twink fucking him from behind. The realization made me so horny as I lowered my face down to the couch and started stroking my dick. I felt his hand start grabbing my ass and spreading my cheeks as he moaned louder. All I did was let out some pathetic moans in response, arching my back a bit for him. We stayed like that for awhile stroking while he stared at and groped my cheeks, telling me how sexy I looked. Eventually he started breathing faster and moaning louder, and I felt him shooting rope after rope all over my ass. The feeling of his cum coating my cheeks and dripping down through my crack and onto my tight hole pushed me over and edge and I started cumming all over his couch. I looked to my left and saw my reflection on the TV and felt a pang of guilt in my chest at what I saw. Myself face down ass up, and him standing over me with a half hard dick, a strand of cum connecting it to my cheeks.

My face got red and we both got pretty awkward pretty quick once the post nut clarity hit. We got cleaned up and I took my girl home and acted like nothing happened. But now a week later he's texting me, saying we should hangout soon and talk. I feel like I know what he wants but I don't know if I should go for another hangout? What do you think I should do?
