After returning home from a company drinking party, Nana Mi Kawakami is forced to take care of her drunken junior colleague. She reluctantly brings him to a nearby hotel and lays him down on the bed, where she notices his crotch is unusually swollen. Ugh, is he actually erect? Young men really do think about nothing but sex, even while asleep... How disgusting, getting so hard like this... Before long, merely smelling him isn't enough—she takes the glans into her mouth, rolling it with her tongue, and eventually swallows him down to the root. Nana Mi's hands won't stop; hugging his penis tightly, she realizes there's no turning back.
