OFSD-046 Big guy! Super-stamina guy! Welcome! Busty young wives at a karaoke box, a wild group encounter. Bored and frustrated young wives spend their afternoon at a karaoke box, ignoring the singing and eagerly flirting with male staff and male customers.

In a karaoke box in the afternoon, a group of frustrated young married women, starved of affection and with too much free time on their hands, spend their days drinking and giving in to temptation. This time, five women gather: Saki (27), a first-time participant; Miwa (30), the fair-skinned beauty who is hosting; Rika (29), a beautiful woman with a model-like figure; Yukari (32), a slender beauty with a sexy charm; and Manami (34), a slender woman with a large bust. They quickly forget about karaoke and get excited talking about romance and desire.

When a male staff member comes to take their order, they immediately turn their attention to him, and the situation quickly becomes heated. It is a wild gathering of women whose pent-up desires have reached their limit. The floor is soon soaked, and the staff member flees in panic. But they are not done yet. Next, they target a young customer in the hallway. They keep going with one man after another, using empty karaoke rooms as they please and causing complete chaos throughout the venue.

As the party continues to be extended, two more married women, Misaki (31) and Mai (26), join in late. Their desire still seems endless. The nonstop revelry continues until there are no more men left to approach, and until it is time for their husbands to come home. Their husbands know nothing about how their wives are relieving their overwhelming desires.
