The latest installment in the popular series featuring a penis-shaped attachment inserted and fixed to a vibrator, relentlessly attacking for extended periods using a timer! With her ultra-sensitive physique, "Monaka" is guaranteed multiple orgasms, and "Mami," who loves bedwetting manga and gets off watching her own videos, delivers non-stop climaxes! As a bonus, we've included footage of "Mami" masturbating with the vibrator right after the timer challenge, sporting a swimsuit and a super-thin leotard!
