My new boyfriend is a bit of a masochist; he always makes me drink his semen. (Nakajo Aoi HBAD-722)

College student Aoi falls in love at first sight with her clubmate Takeshi and decides to date him. However, Takeshi has a masochistic tendency, and every time they have sex, he is choked and forced to perform oral sex. It gets increasingly outrageous, with him being taken for walks with a vibrator attached to him, and even being asked to flirt with strangers and have sex with them. Takeshi's desires grow stronger and stronger.
