The person who was in charge of training him is the capable and very busty Setoguchi-senpai, who's rumored to be unbeatable when it comes to wining and dining corporate clients!

However, today for some reason she seems to be rather defenseless!
Worried about her is the protagonist Morita, who's absolutely determined to see her off to her home safely; and when she immediately heads off to sleep, right on her bed is, surprise, a vibrator dildo!!

Setoguchi-senpai makes the excuse that it's for relieving stress, but when she sees Morita's crotch with a full erection, she tells him "So how about we relieve some stress together?" while baring her heavy boobs to seduce him♪

Morita, who helped her get off with the vibrator, gets told "So can I repay you for what you did for me?" and starts receiving a blowjob from her while she masturbates using the vibrator!

Super popular with dynamic art of busts and hips! Shirisensha-sensei draws a capable senpai showing off her hidden, perverted antics!
