ある雨の日、見知らぬ家出女子○生に声をかけられるボク。どうやら彼女はネットで知り合った今日泊めてくれる神男との待ち合わせだったらしく、間違えてボクに声を掛けてしまった。しかし肝心の神男は現れず、困った家出女子をボクは一時的に保護することに。しかしやはり誘惑には勝てず手を出してしまうボク。すると彼女は、同じように困っている友達も呼んでいいですか？と言われ渋々OKすると、どんどん増える家出女子！最初は一人だったのに最終的には合計4人に！狭いボクの家に4人の家出女子と共同生活！当然ボクの居場所は無い…。しかしその代わりにいつでも抜いてくれるエロオプションがついてきた！しかも個別も集団もOK！こりゃたまりません！

One rainy day, I was approached by a runaway high school girl I didn't know. Apparently, she was waiting for a benevolent man she'd met online who was supposed to give her a place to stay that night, and she'd mistakenly called out to me. However, the benevolent man never showed up, so I ended up temporarily sheltering the runaway girl. But, as expected, I couldn't resist temptation and ended up making a move on her. Then she asked if she could invite a friend who was in the same predicament, and I reluctantly agreed, and soon there were more and more runaway girls! At first there was just one, but eventually there were a total of four! Four runaway girls living together in my small house! Naturally, there was no room for me… But in return, I got the erotic option of them giving me a handjob whenever I wanted! And they were okay with both individual and group sessions! This was irresistible!
