"I'm a red-blooded man too, you know." Kasaya's pushing me down on the bed while cosplaying... Oh no, my hips have gone weak... It feels so good...! I'm Renka, an office worker who's secretly a cosplayer. Kasaya, my senior coworker, looks just like my favorite comic character! I was enjoying myself fantasizing about dressing him up in different costumes. One day, I ended up asking him to cosplay with me, and he said yes!! But when we started the photoshoot, he approached me with a manly expression... "Were you going to do something like this with another man?" Mixing up my insides with his thick fingers... No way, the Kasaya I know isn't this lewd...!
