"Senpai, which of me do you want to sleep with...?" Mamori and Taichi have been dating for awhile, but wouldn't it be fun if they could go back in time and see the world together... before they were together? Well, that wish gets granted... sort of... when a young, virginal Taichi appears! "When I look at you, senpai, my body gets all hot for some reason..." Caught between his boyfriend now and his boyfriend from the past, Mamori has nowhere to go but... down. It's just one night, but two times the pleasure! This story can be enjoyed even as a standalone work.
