[Boukoku Daitouryou] My older sister is confident in the strength of her legs [Apasmara]

A proud older sister brags about the strength of her tights and challenges her little sister and her friend to a two-on-one wrestling match, only to get pinned and defeated round after round by the two smaller girls. What starts as sweaty grappling turns into teasing domination as they strip off her bra, fondle her large breasts and big areolae, and work her nipples until she's crying, gasping, and squirting in a helpless no-penetration climax. A smug big sister's confidence collapses into femdom yuri submission at the hands of her tiny tormentors.
