クラスでボクだけ童貞…。落ち込んでいると義姉が相談に乗ってくれることに！しかも『私で良かったらエッチしてみる？』と提案してきた！お言葉に甘えて記念すべき脱童貞ファック！しかし全然満足できない！超気持ち良いからもう1発！でも足りない。更にもう1発と思ったら、逃げる義姉。そんな義姉を家中追いかけ回してさらに追撃中出し連発！ボクが満足するまで終わりません！

I'm the only virgin in my class… Feeling down, my sister-in-law offered to listen to my problems! And then she suggested, "Would you like to have sex with me if you're okay with it?" I gratefully accepted and had my first ever virginity-losing fuck! But I wasn't satisfied at all! It felt so good, I wanted another round! But it wasn't enough. Just as I was thinking of another round, my sister-in-law ran away. I chased her all over the house and continued to cum inside her repeatedly! It wouldn't end until I was satisfied!
