Not really...
Ueki asks Satsuki if he could do another shoot cuz they are in a bind and they do, this new guy appears as a new AV model and wants to fuck Satsuki but Sudo is fucking Satsuki in front of new guy and is like "No, he's mine" and Satsuki is like "Sudo is the only one for me" (has forgotten that his second shoot was with another guy, all because Sudo tricked him? I guess Sudo wasn't deeply in love with his victim as he is now).
After a company dinner Satsuki is drunk and new guy takes him home and when Satsuki wakes up he's like "hey, sex was fine?" and Satsuki is like "No!", and he is scared Sudo will find out - and agrees to do a AV shoot with new guy, even tells that annoying Matsuri(?) I think that he mustn't tell Sudo about this.
So new guy has three fingers stretching Satsuki's anus, and is like "I finally get to taste Satsuki", but all this stuff with Sudo stresses Satsuki out and makes him literally go unconscious when Sudo barges in.
Sudo takes Satsuki away, Satsuki wakes up, confesses to Sudo that he had sex with new guy, Sudo is disappointed, but it was just sex and didn't mean anything, then new guy comes in and says they didn't even have sex, he just claimed they had sex so Satsuki would let him fuck for work for real.
Satsuki and Sudo go home and have some happy sex.
The end.

I want the seme to suffer tho, really not satisfying
