Yui-san, 22 years old. A fourth-year private university student. She's cute, with beautifully shaped bowl-like breasts visible even through her clothes. By chance, I ended up in a love hotel with this older female senior from university, and while we were showing each other our masturbation, we both got horny and decided to have sex. Of course, we didn't have any condoms, so it was raw. A cute senior who's probably popular, getting satisfied by my dick... Huh? For some reason, her vagina was warm and wet. Thinking "This is...!" I thrust hard, and she moaned with a seemingly pleasurable expression. Taking it as tacit consent, I ended up creampieing her, but the senior didn't get angry at all, just had a blissful expression on her face. Summer.
