Kirie Kawasaki's first experience at an anal-specialty soapland. Drawing on her experience as a married woman, she undergoes professional anal training. Her ass is carefully examined before a vibrator is used to stretch and develop her anus. Overwhelmed by the new sensations, she's shocked and ends up involuntarily urinating. During practical training, the shop manager's huge cock makes its first entry into her ass—she screams at first, but gradually her cries turn into sweet moans. She also experiences immediate blowjob and deep-throat service with a regular customer, then engages in a threesome with the manager joining in, receiving simultaneous double penetration in both her pussy and ass, climaxing repeatedly. In the end, she passionately begs, "Cum inside my ass!" and receives anal creampie twice—an intensely erotic experience from start to finish.
