very basically explained it's like separating ejaculation from climax. you get the feeling of an orgasm, but you don't actually release any semen. sometimes, it can be very painful, in this case, the sub found it to be a good feeling. it usually happens when you wear a cock ring or any other tool that stops ejaculation, and are constantly pushed so near the brink, your body drives over it without actually climaxing.
also, if you're still new to BDSM — this is probably not the best first manwha to read on the topic. excuse me french, but the representation is shit. if you feel like you want to look into it past this, you should definitely do some additional research and try to get in contact with actual doms and subs across the community.
