Yuka Miyoshi's first oral-focused drama begins when she discovers her boyfriend visited a blowjob parlor while she was away. Asking why he went despite having her and whether he loves oral that much, she vows to suck ten times harder than any shop. The supposedly pristine girlfriend immediately gets filthy, continuing oral after the first load and using both mouths in P-to-M sex ending in creampie. Jealous blowjobs continue morning, night, and bath until his cock goes numb.
