Yeah that makes sense [cuckold] [25m/27f]

“Yeah that makes sense”

The background is this:
Over the last few months I’ve been having a lot of trouble staying hard during sex. My gf (of 8 months) has been understanding, but I can tell she’s disappointed. She recently suggested trying to spice things up to see if that helps. We decided on trying to watch porn and masturbate together and then once I’m hard we pause the porn and have sex. This was her idea and it made sense to me so last night we went for it. She had me pick first and I picked the first MF scene that had a cute girl on xvideos on the home page. We watched the like 15 minute video and neither of us ended up being super into it and I couldn’t get hard. Once it was done it was her turn to pick and she said she wanted to try something.

She picked a scene from BlackedRaw (we’re both white) that involved the girl cuckolding her bf and updating him with pics and videos. The guys dick was huge, easily twice my length and girth, which she seemed really into. For me though what stood out was the cuck aspect, and when the girl send a video of herself blowing the guy to her bf I got super hard! I definitely didn’t expect to, I’ve never jacked off to cuck porn.

When I did she noticed and said “yeah that makes sense” and rather than fucking she jacked me off until I came (which didn’t take long) while the video kept playing.

She’s definitely been looking at me differently today, and I can’t get what she said out of my head.

What does this mean? I don’t understand why it was so hot. Am I a cuck? I’ve seen other posters get comments saying they should accept their cuck nature. Do I need to? This is the first time I’ve cum in a couple weeks and the first time I’ve gotten this hard in a while.
