Ai finds Syurina masturbating to the MC’s clothes after he rejected her. Ai wants to help and cheer her up, so she starts seducing and fingering her.
Ai then takes her to Momo and Tohka, asking them to help teach Syurina “The pleasures of being a woman.”
We see it in Ch. 8, but it’s implied after this chapter that they have lesbian group sex in the locker room every day.

Haiji’s sister, Ai, ties him up to the bed and teases him. Momo shows up and thinks the MC is cheating on her, so she starts crying. In order to calm her down, Ai starts making out with her and then proceeds to have sex with her on top of the MC, refusing to let him join in.
The “Cheating” tag is here because in Momo’s mind, her and Haiji are dating, even though Haiji never agreed to it. And I put the “Male Joins” tag here because they have sex on top of him.
