Aoi Kururugi and Nanami Hina are former lovers. Soon after Aoi's current girlfriend, with whom he lives, returns to her parents' home, Aoi's cell phone rings. The voice is that of his ex-girlfriend, Hina. The two broke up over a trivial matter, but when they meet for the first time in a long time, they instinctively press their lips together. They moan as they passionately French kiss, thrust their fingers into each other's slippery pussies, and lick each other's erect clitorises. The next morning, they climax with a full-body kiss, and in the afternoon, their whole bodies convulse from cunnilingus. The three days without his current girlfriend pass by, both of them completely naked.
