After filming ends and Honoka Orihara has showered, the relaxed porn star is invited to join a Standing Doggy Championship. The rule is simple: she wins if she can make a porn actor cum within the time limit using only standing rear-entry sex. Her opponent arrives with his cock rock hard and just as determined not to lose. Honoka sticks out her ass and launches into a hard, lust-fueled fuck driven by pure instinct. How will the championship end?
