[Reducing Mosaic]ROYD-216 Every day, I've been sexually harassing my clear and extremely shy stepsister, turning her into a super sensitive and premature ejaculator. She's become a perverted girl who comes with a lewd face. Hori Kuri no Kitaoka

Due to my parents' remarriage, I got a very cute little sister. However, she is weak-willed and can't refuse when asked, so I went ahead and sexually harassed her! Every day and night, whenever there was free time, I would play with her nipples poking out from her bra-less t-shirt. Whether over the clothes or directly, even if she slightly resisted, she couldn't refuse! She's just that easy to push around! With daily sexual harassment, my sister's nipples were thoroughly trained and developed, turning her into a drooling pervert. In the end, she came to me for the first time and expressed that she wanted to be touched!
