父の再婚で新しい義母になった巨乳（年齢若め）が、乳首が性感帯すぎる雑魚乳首女だと知り…！先輩友人を呼んでみんなで新しい母親になった若い女の乳首開発お泊り会をすることに！！美人でド巨乳な義母。血はつながってないから後ろめたいことなんてないし、自分の家に若い乳首イキしまくる女がいる（笑）状態なので、そのデカすぎJカップおっぱいを何度も何度もイカせまくって遊んだ…！

My dad remarried and my new stepmother is a busty (and relatively young) woman with incredibly sensitive nipples, and I discovered that she's a woman with weak nipples…! So I called over some senior friends and we all decided to have a sleepover to develop the nipples of our new stepmother! My stepmother is beautiful and has huge breasts. We're not related by *****, so there's nothing to feel guilty about, and I have a young woman in my house who gets off on her nipples (lol), so we had fun making her huge J-cup breasts cum over and over again…!
