yeah, that's it, first mom is called Mari, she has had sex with her son, NOT her nephew and has had sex with the son of the third mom, second mom is Kyouko, She has had sex only with her son. and the third mom is Kayo, she has had sex with Mari's son and her own son, not with Kyouko's son.
Hyji kinda tried to switch it up when they were sucking dick in the first onsen chapter, and I was really expecting to see Kyouko get fucked by minoru or at least aknowledge that they're related but they didn't at all, which was weird. I really hope they do now.
