NTSU-038 - Incestuous beautiful mom gives her virgin son his first time 4

Before even discussing the content, the mosaic is so thick that you can barely tell if it's phimosis or not. Despite the premise of 'first time peeling back a son's phimosis,' they only touch on it briefly before just peeling it back and proceeding as usual... There are even actors who don't seem to have phimosis at all from the start. It's a very disappointing work because it's nothing like what the title suggests.
