While the MC is having sex with Shieri, Rin and Ann briefly join in by groping Shieri.
While they’re sucking on her breasts, 1 of them mentions how they did this all the time in the past, implying they’ve had lesbian threesomes before.
Eventually Rin and Ann stop to just have lesbian sex with each other in the background.
So I’m gonna tag this as Male Involved, but the MC doesn’t do anything with Rin and Ann after they leave to have lesbian sex.

The MC has an orgy with Shiroha, Ao and Ai for most of the chapter with yuri moments in it.
At the end of the chapter, the MC passes out, so Ai takes the opportunity to have lesbian sex with Ao and Shiroha.
It then cuts to black, and when the MC finds them again, he finds that Shiroha was NTR’d and is now in love with Ai, so Shiroha completely ignores him.
