Toy for a week (Pixiv Fanbox)

Who wouldn’t dream of having a cute girl as a personal toy for a full week? The dungeon makes it possible: All you have to do is give this trapped trainee the biggest bulge~ First take a condom, then go as deep as you can physically manage and mark your score with a marker on her belly. Of course, having penetrated her already you might as well finish off yourself while you’re at it~ The biggest bulge wins an all-expenses-paid week in the dungeon together with this relatively obedient trainee. Go and take your chance~
