KING-139 Limited to highly educated female college students passing by! Why not try rubbing through an ultra-thin sheet that feels even better than direct contact? With body heat passing through the ultra-thin barrier, a sensitive body becomes so aroused that the wet sounds just won’t stop. Pretending it was an accident, she takes the initiative and presses herself against a large manhood… (KING-139)

22-year-old law student, track club member, Kansai dialect, sidelong glances, reserved, and a high-achieving college girl who goes out with her boyfriend every day, “Matsuri” is approached with a high-paying part-time job offer and taken to a special studio. With her Kansai accent and alluring gaze, her tight dress highlights her curves and gives her a sexy look. She says, “Every day with my boyfriend, I’m the one who wants to take the lead…” and this sultry older-sister type is introduced to today’s main topic: a monitoring project for an ultra-thin sheet developed by NAS〇.

“Not sure what to do… I do have a boyfriend…” she hesitates, but when stacks of cash are placed in front of her, she starts taking off her dress. When the sheet is placed over her intimate area, she lets out a soft, Kansai-style gasp. As it is gently traced from above, she says, “Th-this is a first…” and “It might feel kind of good…” In a side-by-side position, she moans, “N-no…” and “It feels even better than usual…” Her body writhes as she says, “It’s not cheating if it’s through the sheet, right…?” and “This is just a serious monitoring test…” but also, “B-but it feels so good…” Unable to hold back, she straddles him and, while asking, “What should I do?”, moves her hips skillfully with a playful smile.

At last, she says, “Huh? Wait… this is going in, right?” and boldly continues the act with the sheet still in place. She enjoys it so much that she reaches climax in a wild, messy state. She becomes completely overwhelmed and finishes with a release on the sheet. “I can’t tell unless I compare it to the real thing!” she says, then eagerly gives oral attention, using an enticing tongue and upward gaze. Her sensitivity rises as her chest is stimulated. Once the real thing is inserted, desire wins out. In a rear riding position, she bounces her hips with a firm rhythm. “After all, it feels better without the sheet~” she says, fully giving in to desire. The ultra-thin sheet’s effect is amazing. Isn’t it dangerous to get this carried away?
