(Did you know there are 100 types of cowgirl position?) Kei, who is the master's favorite, is a maid specializing in cowgirl position for life. She shakes her hips eternally with her well-trained doll body. From cowgirl gripping the glans to spiral cowgirl compressing the base. Reverse cowgirl→uterine muscle pressure riding position, always serving with pussy! Also shows off her natural airhead tendencies by coming on her own in a self-induced orgasm riding position... but she's just a COWGIRL who wants to keep fucking forever. Wants to see the master's eyes and make him happy. Even if manjuice turns into meringue, it'll be shaking that ass thump thump.
