Our guest today is Yui, a female doctor. While she seems a little nervous, she exudes a mature composure. Due to her job, she often attends business executive parties, and has even spent the night with them. Yui has had around 100 sexual partners, making her highly experienced. She's sexually voracious, even finding rare opportunities to have sex. "I enjoy both giving and receiving punishment," she says, happily revealing her love of spanking. She applied for this session because she wanted to experience something different with a male actor. As we enjoy her smooth skin and undress her, we reveal her sexy underwear and toned body. When the actor removes his pants, she rubs her ass against his bulging penis through his underwear, wiggling her hips in a lustful yet seductive manner. With her hands tied and restricted, Yui's erogenous zones are stimulated, and she orgasms, her body trembling with the constant pleasure. After vigorously stirring her pussy, which has already taken in over 100 cocks, with a finger and making it soft with a vibrator, she inserts a thick cock, and with each thrust, her insides and body twitch, feeling it with her whole body. At the end of the intense thrusts, she is left in a daze, immersed in the afterglow on the bed.
