Bikini Girl Exclusive! 30-Second Horseback Riding Challenge on a Balance Ball! 100,000 yen prize for 3 successful attempts! Despite struggling to clear it, she keeps trying, even resorting to a dildo-equipped balance ball... But she's repeatedly interrupted by a persistent, fully erect cock, leading to a sex penalty game! She's relentlessly teased with toys and kept riding face-down! The thrusting on the bouncing ball leaves no escape, and he keeps driving deep inside her! In the end, as promised, she gets creampied by the girl in the penalty game!
