Aoi Aoi Shirasaki, a naturally erotic girl, appears, seducing the cum-swallowing enthusiasts with her friendly smile and showing off her lewd and bold drinking style. At first, she encourages the participants by saying, "I'll do something good to the person who makes their penis bigger♪", and then she gently and erotically supports the hard-working men, squeezing their sperm one after another. At the climax, Aoi, who has smelled the sperm, stuffs one cock after another into her mouth, showing off the excess juice with her mouth and drinking it up with relish.
