I giggle like a little sh*t everytime whenever they naturally do a roleplay when they get so horny or about to have sex. Like omfg, I can't even get horny with them because I cackle whenever I read their dialogues during sexy time. You can always see what keeps them going in bed and I like that they naturally do it by just observing each other.
If this was omegavers Naoto (MC) would be popping babies left and right because oh my ghad they're so freaky for each other uuuggghh.
