After the MC reveals to the girls that he saw them having sex in the previous scene, they kidnap him and tie him up.
He then blackmails them saying he’ll keep their relationship a secret if he can watch them have lesbian sex with each other.
They reluctantly agree and allow him to watch and masturbate to them having sex.
This continues into the next scene.

Influenced by Akashi, Sekai and Ushio briefly have a lesbian threesome with Domeki.
But the MC quickly joins in as well and the rest of the scene remains an orgy with him involved.
There’s a few colored pages of the orgy part of this scene back in Chapter 41.

Continued from the previous scene, Julia and Leo engage in lotion play while the MC watches.
Pretty quickly though, Julia gets more and more aggressive, turning the scene into full on lesbian sex.
Julia even starts to tease the MC about getting cucked by another woman, but he’s completely fine with it because it’s hot.
While showing reluctance to Julia’s previous advances, Leo gets very turned on here and begins to enjoy the girl-on-girl action.
The MC never joins in at any point, he only watches.
Personally speaking, this is probably my favorite scene I’ve added onto the manga list so far.
Even though the MC is fine with it in the end, I have the Cheating tag here because of the NTR dialogue Julia has.
