[My younger sister, who was born through my parents’ remarriage, is a rumored urban legend-level slut! ? ] Miru, my father-in-law’s stepchild, is a bitch gal who catches men on the street and enjoys sex. She is incredibly cocky and makes fun of me, her older brother, calling me “uncool,” “boring,” and “smelling like a virgin.” But, as expected, I gradually started to feel pleasure being played with by my girlfriend… One day, when I was jerking off in the living room with an erotic book in hand, my girlfriend’s sister masturbated! She ends up witnessing his erect penis. I thought that she was crazy and would definitely make fun of me again, but she unexpectedly responded, “When it gets erect, it’s a pretty good dick!” ? ‘It’s my first time being touched…? Well then, how should I take your virginity? ’ and the conversation progressed at a rapid pace, with the stoppage, crunchy nipples, and countdown ejaculation, a shocking first experience that was too stimulating for a virgin! Since then, we have crossed the line and started having sex everywhere… Morning erection cock blowjob, kitchen secret rape, yukata sex at the end of the festival. My little devil sister will do whatever she wants to me all the time!
