Hmm, the uke is aware that they were indeed having sex after the Seme said that playtime is over. The uke remembers the scenes in his mind (them fucking) and thought that they really did (thinking that it was consensual both side and he was aware) so they continue (tried to) but the seme saw him pukes so they stopped (the seme asked to) after that, the seme doesn't touch the uke anymore and the uke became conscious of it (especially sex).
The uke is aware. That's why he's conscious about it and eventually lust after the seme.
He was aware that they are had sex, the one that he's not aware is that he was manipulated. I hope I answered your question!

If it helps you, here's a summary:
- Seme and uke have a lot of sex under hypnosis, and uke forgets about it when "play time is over".
- There was one time seme was drunk and felt up uke (not during hypnosis). The normal uke remembers this; and freaks out about fantasizing it.
- Eventually they have sex again during hypnosis, but the seme who wants more than a physical relationship undoes the hypnosis in the middle of it, and both "consciousness" of the uke start to merge.
- The seme sees that the uke isn't actually taking to it well, as both personas are starting to clash (the one that wants to be close, and the one that hates him), and casts another hypnosis for him to forget everything, including playtime.
- Fast forward to the current uke, who doesn't consciously remember anything but still subconsciously does. He gets flashback hornyness because he remembers the time the seme felt him up when the seme was drunk (that one time not under hypnosis); but his physical body also is remembering, even if his consciousness is not.
So before he made him aware after saying that playtime is over, then the uke was like pretending it was ok but then the seme find out he was just pretending because the uke pukes his baby slimes into the bowl then made him forget everything, so tye uke wasn't aware of anything again?? Is that what happened?
