The latest installment in our popular series, where a penis-shaped attachment is inserted and fixed to a vibrator, and a timer is used to relentlessly attack for extended periods, features the charmingly innocent smile of "Ena-san" and the slender "Yukino-san" who screams with ecstasy as her waist shakes repeatedly! As a bonus video, we've also included footage of her masturbating with the vibrator right after the timer challenge, wearing a super-thin leotard!!
