[Umemaro 3D] Vol. 4 Mai

Mai waits for her boyfriend in the gym storage room. When he arrives they begin with a blowjob and titjob before moving to sex. During the act two of his friends enter and join in. What starts as a private moment becomes a non-consensual group scene, though Mai quickly appears to enjoy it. This 2004 release is the first Umemaro title to feature returning characters (Sasa appears briefly) and the first to include non-consensual elements. The expanded narrative focus and multi-character interaction marked a step forward from the earlier pure-sex shorts.
