It Doesn't Have to Go In

Overview

Toma is a large man who works doing manual labor, while Hiro is a dainty guy who's very passionate about various causes. They meet at a movie theater and hit it off quickly, going out for a drink afterwards to discuss the movie they saw. From there, things escalate to kissing and eventually they end up in a hotel room. However, Toma is packing more than Hiro could have imagined, so they decide to try other ways to make love other than putting it in directly. While this is enjoyable for both of them, Toma begins to worry that it isn't enough to satisfy Hiro and looks for ways to help them go all the way.
