New series "Standing Doggy Style Championship" begins now! First up is Koiori Kurumi, petite at just 148cm, yet boasting Holstein-level giant breasts. With her explosive bust perfectly accentuated by her figure, she's a top contender with incredible visual appeal during standing doggy style. The rules are simple—victory is achieved if she makes him cum within five minutes after penetration. Foreplay time isn't counted, so enjoy plenty of cunnilingus, blowjob, and massive titty fuck to build arousal. However, get too excited and he might climax too soon—countdown starts 20 seconds after insertion. The intense standing doggy style, with her ultra-sensitive massive breasts bouncing wildly, is shot with such erotic intensity it'll make you swallow hard. Watch the main feature to see the results!
