Mizugi Shimai Eroero x Tsuntsun x Hentai!

A letter from your late father brings you back to your hometown, where three sisters from childhood are waiting.
Each one individually offers her virginity to you, and even a threesome is possible.
Who will you honor with being her first time? Will you make her pregnant, or......
It's all up to you! Just be aware you have a limited amount of spunk to give.

Home is a remote seaside villa surrounded by cliffs on three sides
leading out to the ocean. There are no buses or railways here, just a local ferry, and it only comes two or three times a week.
It's a secluded paradise, complete with rare tropical fish and the like.

School runs on an all-ages integrated program, and though town is wealthy and the school is private, there are no indoor pools.
Just the beautiful outdoor pool. Shower rooms, lockers and facilities are kept immaculately clean.
