"Why did I make such a lewd expression and feel that? ※Inner Voice" Sexually harassing his extremely introverted stepsister every day, resulting in her becoming hypersensitive and prone to premature ejaculation, experiencing constant orgasms! 4 perverted women… HUNTC-454

I have an introverted and timid stepsister. Since we're family, she dresses provocatively at home in her pajamas and without a bra. To be honest, I find her very feminine. So, my self-control reached its limit, and I finally touched her… Oh no! I'm going to get yelled at! But the result was unexpected. I felt shy! I wondered, could this be…? Then, every day at home, I stimulated her nipples, and she became increasingly erotic! Since that's the case, we can definitely go all the way! No, we definitely can! I think I stimulated her nipples too! As a result, she writhed all over, drooling, and her vagina was soaking wet! Since I didn't have to worry about being discovered by our parents, I thrust my penis in hard! From that day on, my stepsister became my sex partner.
