Senjougahara gropes and rubs against Hanekawa’s body while they take a shower together.
The scene is only a minute, but Hanekawa’s text narration during the black screen says they had fun with each other in the shower for half an hour off-screen.
Afterwards, Senjougahara begs for Hanekawa to sleep in the same bed, stating she won’t lay a finger on her, but ends up cuddling with her.
This bath scene is very sexual for fan service reasons, so due to that, I’m going to give this the Cheating tag, even though it probably doesn’t count as cheating for Senjougahara.

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.
