About this work

At the GEKI-Rare Sex Science Lab we solve various sexual concerns while experimentally testing sex science topics. This time is the story of a female college student whose entire body is covered in erogenous zones and is overly sensitive. She has a unique problem: she feels aroused when someone touches her back on a crowded train. Apparently she can climax from very slight stimulation, so to build tolerance we relentlessly attack her whole body nonstop using orgasm devices and a チ○ポ (censored penis)! This footage examines how long of continuous stimulation it takes for her to experience orgasm-induced fainting (fainting from pleasure).
