[Reducing Mosaic]ROYD-066 My childhood friend and little sister like me too much, seducing me out of jealousy, stealing my heart. Aoi Suzuki Yuna Himekawa

My childhood friend and I have been together since we were little, always aware of each other but unable to take the next step. I thought this relationship would continue forever, but one day my parents remarried, and a stepsister from the city came to live with us. My stepsister is promiscuous and free-spirited, suddenly getting close to me and confusing me. My childhood friend gets jealous of my relationship with my stepsister and tries to pull us apart while also trying to seduce me. My stepsister doesn't back down either, trying to seduce me as well, leading to a threesome?!
