This is a video that those who believe male-female friendship can work absolutely need to see. Please watch how the friendship between Mina-chan (19) and Shoma-kun (19) collapses—or rather, reconciles and warps—through sex. This documentary, which ultimately develops into creampie sex, spans about three hours, letting you feel the emotional shifts and the changing distance between the two. All in all, it was insanely erotic.
