I mean, The situation with him, Satsuki, and Ishihara has been escalating for a while, and it has an amazing: build-up, story, and display of breasts from the perfect MILF-yandere mom-gf combo that surpasses any hentai. Gosh, I can't stop gushing about this. All over my keyboard. Can't wait for his climax!
