A term that refers to the state of loosing all sense of rational thinking and
comprehension of the world around you during
sexual intercourse. It's pretty often displayed in hentai, and it can be a kink for some people.
It is also a thing in the BDSM world, where you take your sub, usually bratty, and put them through an intense session of sexual torture or
overwhelming pleasure, that leaves them in a sort of daze. Make sure they don't go into sub drop, though.
