Tanetsuke Dosukebe Undoukai! The Motion Anime

Animated comic "Tanetsuke Dosukebe Undoukai! The Motion Anime" was made based on the CGI manga of the same name by the circle Pan to Butterfly, aka Tokei Usagi. Every year, a festival is held at the Doskebe Sports Academy where anyone can have sex if they win a competition. Mostly it's, of course, parents, teachers, and students. At this pseudo-sports festival, anything goes!
