ROYD-270 — After Teasing My Innocent And Extremely Shy Stepsister Every Day, She Becomes Super Sensitive And Prematurely Ejaculates! She Suddenly Transforms Into A Perverted Girl Who Cums Over And Over With A Lewd Expression On Her Face. Otori Miyu

My parents remarried and I got a step-sister... She was a timid, timid girl who couldn't say "no" to things she didn't like. She was so defenseless that she didn't even wear a bra around the house... I couldn't help staring at her, so I started poking her nipples every day through her T-shirt... poking, poking, poking... rubbing, rubbing... Taking advantage of the fact that she couldn't say no verbally, I continued to tease her every day, and her reaction seemed to get better and better. Her pussy got soaked in no time, and she became completely sensitive and prone to premature ejaculation. In the end, she turned into a nymphomaniac girl, so much so that she even asked me to touch her nipples!
