彼女の自宅に遊びに行くと、いつも夜勤明けの巨乳のお義姉さんが寝ていて…。聞くと看護師として夜勤で働いているらしく、いつもおっぱいをはみ出しそうにしながら油断100％な姿で熟睡していて、理性を保つのに必死なボク。ある日お義姉さんとボクを置いて出かけて行った彼女、無自覚すぎるおっぱいと一つ屋根の下に置かれたボクは、出来心でついついおっぱいを揉んでしまう…！あれ…全然起きない…？イタズラはエスカレートしていき、顔を埋め、舐め回し、チンチン挟んでも…起きない！！！好き放題にできるおっぱいを手に入れたボクはおっぱいでヤリたかったあんなコトやこんなコトをヤリまくる…！！！
When I went to my girlfriend’s house, I always found my big-breasted sister-in-law sleeping after her night shift… She seems to be working the night shift as a nurse, and she’s always sleeping soundly, her breasts almost sticking out, completely alert, and I’m desperately trying to keep her sanity. One day, she went out leaving me with her sister-in-law, and I was placed under the same roof as her breasts, which I was unaware of, and I couldn’t help but fondle her breasts…! Huh…it doesn’t happen at all…? The mischief escalates, even if he buries his face, licks him, and pinches his dick… he won’t wake up! ! ! Now that I have breasts that I can do whatever I want, I’m going to do all the things I wanted to do with them…! ! !
