Summary: This offering from the circle Seitokaishitsu features characters from the hentai game turned anime Fate/stay night. The buxom beauty Rin Tōsaka is instructing Shirō Emiya in a little sorcery training before they hop into the pool for a little R&R. That bathing suit must bring out the freak in her because Rin starts putting the moves on a fluster Shiro, and, well, you can imagine what happens - or better yet, read it. Enjoy!
