Daisuke actually wanted to treat himself to a relaxing beach holiday that was also a feast for the eyes: he is therefore looking forward to seeing plenty of well-built beauties in skimpy bikinis. He does not deny his penchant for ample breasts and is all too easily tempted by women with such endowments.
In fact, his trip turns into a rollercoaster of pleasant and exhausting, because two fellow students, Nao and Mitsugu, have come to sweeten his stay; he also unexpectedly meets his cousin Maya, whom he hasn't seen in ages, as well as her work colleague Momona, and makes two hot holiday acquaintances in Mika and Kanae. He sometimes feels overwhelmed by the offensive sexual courting of him, but he is quite happy to let the ladies do what they do to him.
