FJIN-089 - My step-sister, created through my parent's remarriage, is a sexually promiscuous woman. Despite being sloppy, she was overly erotic, and I was gang-raped by my defenseless, large-breasted sisters... Yumi Shion, Aikawa Suzu

Due to my parents' remarriage, I gained step-sisters for the first time at this age. And two at once! This is nothing short of an achievement! And, just between us, both of them have large breasts. As someone who has never been popular, I find it a little awkward... Just as I was indulging in my sentimental feelings, the embodiment of sexual desire, inflated by my sisters' erotic manga, activated with my immature erection and exploded! A vigorous sex far removed from love or romance, with plump, large breasts shaking. I've discarded any desire to be popular or to fall in love, and the instinct hidden deep within women who charge forward is truly erotic and dangerous.
