Trainer Yuika Onosaka tempts a male student. "Yes! Put your hips deeper into it like a teacher!" She captivates students with her attractive figure and flexible poses. To attract new members, she tempts students during a balance ball lesson, revealing her sweaty body. Ultimately, the students succumb to her charm and engage in a three-person sexual encounter. Her provocative appearance is a must-see.















*As the title suggests, this work focuses on butts. It was designed to show off her butt, allowing you to fully enjoy Yuika Onosaka's big, beautiful butt, and it was a content that butt lovers couldn't resist. Karami had one shot in the first half and one in the second half, with a 1-on-1 in the first half and a 3-point shot in the second half. Since the main focus was on her butt, it was inevitable that the scene was mainly from the back, but it was really erotic to see her butt cleavage spread to the left and right, exposing her exposed anus. Personally, I think the 3P Karami was better. This is a work recommended for people who like butts.
