TMCY-115 Being lumped together with a party girl circle is extremely unfair, Aoi Kururugi

A sex research club said to exist at a certain university. The only female member is the cutest girl in the biology department. She works seriously every day! Her task is to apply various forms of stimulation and observe the results. She is even willing to devote her youthful body to the cause. She provides close-up reference material of the most important parts. By challenging unusual positions and repeated intense climaxes, she explores human sexual instincts under extreme conditions and reaches the depths of pleasure.
