We picked up a pair of college girls in Shibuya and proposed a slightly erotic game that would help them lose weight and stay healthy! They competed in a very embarrassing position on an acrylic board! Which girl would win?! They were confused by their first fixed dildo insertion, but they had a climax that exceeded their K-points! The two bewildered fair-skinned girls' vaginas endlessly released orgasmic water! A punishment game of immediate sex with a huge dick for big tits! Their vaginas were repeatedly poked with a huge dick, making their legs twitch and their vaginas orgasm, causing a brain bug! Let's have some sex exercise!
