After a company drinking party, Nanami is forced to take care of a drunk junior colleague. She somehow manages to get him to a nearby hotel and put him to bed, but suddenly notices that his crotch is strangely swollen. Oh no, I wonder if he's erect... Even when young men are asleep, their minds are filled with erotic thoughts. It's so erotic to see it get so big... Before she knows it, Nanami has pulled down his pants and can't take her eyes off his rock-hard cock. Not content with just sniffing it, she takes the head of his penis into her mouth and licks it around with the tip of her tongue... and finally swallows it all the way to the base.
