まるで拷問… 絶対に手が出せない無防備な巨乳姉達と添い寝する事になった僕。 君島みお 宝田もなみ (2018)

Sandwiched between beautiful busty sisters in the shape of a river... I faint in agony until the morning with a torture-like temptation! I had an older sister because of my father's remarriage. The eldest daughter, Mio, and the second daughter, Monami, are beautiful women with outstanding style, and it was exciting just to live under the same roof. Even so, my sisters' room wasn't ready, so I ended up sleeping in the same room with the character of the river. There was no way I could sleep in such a situation, and when I looked next to me, my exposed nipples and protruding thighs... I was sandwiched between my sisters and tempted like torture...
