Some guys squirt cum like a mini firehose, so the lack of "evidence" in me or on me would tell the story. However, a few guys I know will occasionally cum only a few drops, or maybe one tiny spurt. This usually happens if it has been a day and/or night of sex and cumming for him - his "cum glands" only have so much backup juice and it takes time to resupply. So if he's in me and goes "all orgasmic", I might not be able to distinguish between his precum and my own pussy juices and a tiny amount of cum. If I'm sucking on him and he cums in my mouth - different story. Precum and cum feel and taste different, and I can feel the subtle changes in cock hardness and texture when its in my mouth.
So I guess it is possible for a guy to fake an orgasm and not get caught.
Yes. Many men orgasm without cumming.
But you can still tell when it is genuine by their body language.
I seem to write a story every 1.5 years on average.

I didn’t have one but my partner clearly did and really enjoyed herself and if it would’ve been insensitive if I’d have stayed with it until I did. Snuggled and fell asleep. The next morning we woke up and she asked if I had an orgasm and I was honest and said no. She was hurt and pouted for a while but then came back on a mission 😁. It was our last date and we had like three dates but she had a drinking problem and it turned me off. She die two years later at 37 from liver disease so I still feel bad I just parted ways without telling her why…maybe?
