My younger sister, who was born after my parents' remarriage, is a cheeky but sex-loving gal and I'm cumming every day.

[The younger sister who was born after her parents' remarriage is a slut that is rumored to be a rumoured urban legend!] Miru, the stepchild of her stepfather, is a bitchy gal who catches a man in town and has sex. She is extremely cheeky and makes me, my older brother, go crazy for being "uncool", "dull," and "virgin-smelling." But perhaps it's just that she plays with me gradually starts to feel pleasure... One day, while in the living room, she was masturbating with a sexy book in her hand, her younger sister found out she was masturbating! He is spotted with an erect cock. It was crazy, and I was sure I would make fun of him again, but then he responded with an unexpected reaction, "If you get an erection, you're pretty good at dick"!? "This is the first time I've ever been touched...? So, how should I take my virginity (a virgin)?" The conversation progressed in a flash, and the nipples were crispy and countdown ejaculated, and it was a shocking first experience that was too stimulating for a virgin! Since then, after crossing the line, we have started having sex everywhere... Morning erections with a dick blowjob, kitchen rape, and yukata sex at the end of the festival. She is raped by her little devil sister all the time!
