The new standing doggy-style championship begins with petite 148 cm Kurumi Kogoromo and her enormous breasts. The rule is simple: make the man ejaculate within five minutes of penetration to win. Foreplay does not count, so she raises his excitement with generous cunnilingus, a blowjob, and a huge-tit titjob before the clock starts 20 seconds later. Her sensitive breasts swing wildly through the powerful standing doggy pounding. Watch the full feature to discover the result.
