地域の掃除も快くこなす隣人の女子大生・まりのさん。しかし彼女は常にノーブラで胸ポッチ。そんな無防備な姿に悶々と欲情していた。ある日、水道の調子が悪いと相談され、彼女の家を訪れると、不意の放水で彼女は濡れ透け状態に。理性を失ってしまい、溜まりに溜まった衝動はついに暴発する。
My neighbor, Marino, is a female college student who willingly helps with neighborhood cleanups. However, she's always braless, with her nipples showing. I've been tormented by her defenseless appearance. One day, she asks me for help because her water pipes aren't working properly, and when I visit her house, I accidentally turn on the water, leaving her soaked and see-through. I lose all self-control, and my pent-up desires finally explode.
