Who says cis women can't have toy-free missionary sex? :D
Momo and Kyoko have bondage sex for the first time, in the dead of night, in Kyoko's dorm room. Gotta keep quiet of you wanna make sure nobody hears you! Dorm walls are really thin, y'know. I made Kyoko be the one to cry out since her superpower includes making loud noises, lol.
Also I was trying to make them a bit shinny to show that they're sweating and have been at this for a while. Hopefully that comes across!
