RPGM The Wreck of the Spaceship Todoroki

The Wreck of the Spaceship Todoroki is a natyusyo RPGM Japanese game following Izumi and John, two recruits on their final test before landing a job at a space development company. Their tiny ship collides with the Todoroki, a much larger vessel used for secret experiments, and they have to board to free their ride.

The Todoroki carries a Mysterious Being X that requires three injections to ward off its influence. Izumi has one. The other two are somewhere inside the ship, so the pair starts a methodical search. The catch: the injection has a side effect, and Izumi gets hornier with every dose.

The 2DCG art carries the cast across the ship, and content threads pregnancy beats, exhibitionism, group sex, lactation, oral, titfuck, sexual-harassment scenes, big-tit / big-ass character work, and the kind of consequence the female protagonist journey is built on.
