My little sister, who still has the same cute, youthful face she had in school, has recently started showing a surprisingly erotic side. I found myself drawn to her, and when she begged me to experience a love hotel with her after getting a boyfriend, I ended up going along. It started with her washing my body intimately in the shower, then she gave me a mischievous handjob that I couldn't resist—my cock instantly became rock hard. I didn't just lose control, I erupted completely, and we moved to the bed. Despite her childlike face, her breasts had grown far larger than I imagined. Even after the handjob, I got hard again and hungrily attacked her chest and crotch. She must have learned somewhere, because she started performing titty fuck and even nipple licking. Moaning sensitively as she came repeatedly, grinding her hips in sharp, jerky motions, she drove me wild. Unable to hold back any longer, I pinned her down and pounded her from behind with fierce doggystyle thrusts, eventually exploding inside her with a creampie.
