The first Standing Doggy Championship features 148-centimeter Kurumi Kogoromo, a petite adult with colossal breasts made for this position. The rule is simple: make the man cum within five minutes of penetration to win. Foreplay does not count, so she primes his cock with plenty of cunnilingus, oral, and a huge-tit titjob—though they wait twenty seconds after that intense warm-up before starting the clock. Kurumi’s sensitive breasts swing wildly as she is pounded standing from behind. Watch the full video to discover the result.
