学生時代、兄貴は実家に彼女(あいかさん)を連れ込んでは隣部屋でセックスしていた。可愛くて愛嬌があって胸も大きくて…そんな最高な彼女がいる兄貴が羨ましかった。出張で上京すると連絡したら泊めてくれるこに。久々に再会したあいかさんは…無防備、無警戒すぎるノーブラ姿でドキドキ戸惑ってしまった。残業で帰りが遅い兄貴とはセックスレス…こんな魅力的なのに勿体ない!衝動的に押し倒したら欲求不満なあいかさんは…。 When I was a student, my brother brought her (Aika) to his parents’ house and had sex in the next room. She’s cute, charming, and has big breasts. If she contacts me that she is going to Tokyo on a business trip, she will let me stay. Aika-san, who met her again after a long time, was puzzled by her unprotected, unsuspecting no-bra appearance. I can’t have sex with my older brother who comes home late because of her overtime work… It’s such a waste to be so attractive! Aika is frustrated when she pushes her down impulsively. -
