Mahiro Yui is driven through orgasm after orgasm with a brutally powerful thrusting vibrator and relentless follow-up pounding. Crying that she has already cum and is about to cum again does not make it stop: the deep thrusts keep hammering her cervix until she convulses and squirts uncontrollably. A high-speed drill vibrator and an extra-thick cock alternate endlessly, leaving her dazed and cumming wildly.
