BKYNB-056 A plain big-breasted girlfriend is cuckolded by her friend's shiatsu therapist and begs for creampie Yuri Aise

Description

My girlfriend is a plain otaku but has big breasts, and her modesty makes her easy to get along with, even for an otaku like me, so we lived together happily, staying at home together. One day, a fellow otaku friend came to visit us. He apparently works as a shiatsu therapist at a massage parlor. We usually just sit around playing games as a couple, so we decided to give him a shiatsu treatment...She's never been touched by another man before, so her reaction was a little strange...could she feel something from the shiatsu?
