Yukari-san (50), a secretary with a Swedish husband who is particular about underwear, has long limbs and beautiful legs that don't seem to belong to someone in their fifties. She was made to change into lewd underwear that couldn't hide her nipples, walking outside with the bulges visible even through her clothes. Additionally, she was fitted with a remote-controlled vibrator and forced to expose her buttocks on the echoing staircase for humiliation. Each time the switch was turned on, her buttocks would twitch, clenching to keep the vibrator from falling. Her ass was incredibly erotic in this state. Even after returning to the room, she continued to be relentlessly stimulated in that condition, and her private area was soaked after the vibrator was removed. She was then vigorously penetrated with a vibrator, reaching orgasm. Finally, she wouldn't let go of the penis inserted from behind, writhing her hips and thrusting against it herself. Even in the cowgirl position, she savored the pleasure with long strokes and reached orgasm. Perhaps she had become too sensitive, as she climaxed multiple times in the missionary position, shaking her body each time, ultimately having semen deposited deep inside her vagina.
