Akari Yamazaki surprises a friend in his room, discovering him masturbating over the pages of a magazine. He struggles to conceal himself, but Akari, in a tight yellow top and black leather skirt, stands over him, examining the magazine in his hands. Akari decides to take her friend in hand and lifts her top, her huge breasts spilling out. He soon fondles, teases and licks them, enjoying their size, then helps Akari out of her panties and licks her pussy. Akari ends the lesson with oral sex.
