YSN-393 I tried to make my overprotective older sister hate me by forcing her to wear erotic underwear, but not only did she put it on right away, but she was fidgety and excited about the situation, and when I saw her, I was disgusted. - I was so excited that my dick became extremely erect.

My older sister has been overly protective of me since we were little, treating me like my own son, and she doesn't like me having a girlfriend or looking at erotic books or DVDs, even though I'm so enthusiastic. - I couldn't hold back my sexual desire, so I bought some super erotic underwear and tried it on for my sister, and she put it on despite being shy, but it was so erotic that she couldn't help but get an erection. - My older sister notices the erection in his crotch and is drooling as she stares at it, so I jokingly say, ``Why don't you try licking it?'' Suddenly, she takes my cock deep into her throat, so it's just how she likes it. - I tried it.
