Soft-skinned, deliciously curvy Mirei Imada takes on the Cowgirl Time Trial. If she can make a man cum while riding him within five minutes, she wins a prize; if not, she faces a kinky penalty. She gets his cock hard with a blowjob, slides it inside, and starts the clock. Mirei slowly rolls her hips up and down, mixing rhythmic vertical strokes with side-to-side grinding to stimulate every inch. Her experienced technique combines powerful pressure with smooth, seductive control designed to bring him to orgasm.
