Agi, an office lady, struggles with unsatisfying sex with her boyfriend and asks her senior at work for nipple play training. Her senior torments her nipples with both tongue and vibrator, making Agi writhe and scream, "That's weird—my boyfriend always says he doesn't feel anything!" Next, she crushes the man's face underfoot while giving him a handjob to ejaculation, then straddles him on a chair, mounting his face aggressively with her thick lower body. Using crotch-grinding face sitting, she presses her thighs tightly, then crushes him completely with her full weight until he surrenders. Wearing a tight long-sleeved swimsuit, she dominates him further, using heated twisting and squeezing motions with her fleshy thighs to intensify the stimulation. She spreads her legs in a wide M-shape, smothering his head, grinding her pelvis lewdly against his face until it's drenched in her juices, and relentlessly teasing him with her foul-scented, wet face riding.
