The MC invites Kukuri over to his house, who he has a crush on, but it’s revealed that she is in love with his sister, Esuka. The scene then progresses into the MC having a threesome.

Esuka finds out how good Kukuri is at sex and likes how it tortures the MC, so they have lesbian sex on top of him.

At the end of the chapter, Esuka says she won’t have sex with the MC anymore and she only will with Kukuri.

At the start of Ch. 6, there’s a time skip and Esuka has stopped having sex with Kukuri, but it’s implied they did at least hook-up after this scene a few times off-screen.
