Moka-chan (20 years old), innocently playing at the beach, is approached and challenges an erotic project of "1cm 10,000 yen dildo challenge" on the Magic Mirror Ship! A healing-type amateur girl with a plump, big ass and a swimsuit covered in sand that is dazzling. Enticed by the prize money, she shifts her swimsuit and nervously straddles the slippery dildo! She teases him saying "Just the tip...", but succumbs to pleasure and slides all the way in! With a crab stance, her pussy is soaked, and her big ass shakes in a crotch-shot angle! "Fuck!" she orgasms repeatedly on the dicks of men other than her boyfriend! She even decided to creampie!
