Haruka Akane and Mukai Riku, national champion runners, find themselves alone in the locker room after practice. Tired of the strict regime, they decide to indulge in a secret passion. Haruka, with her luscious curves and big, natural tits, leans into Mukai, her pregnant belly pressing against him. They share a deep, lingering kiss, their bodies trembling with anticipation. Mukai's hands explore Haruka's perfect ass, while she unzips his track pants, revealing his throbbing cock. They move to the nearby bathroom, the sound of running water and their ragged breaths filling the air. Haruka sucks Mukai's cock, her eyes locked with his, before he lifts her onto the counter, her legs wrapped around his waist. He slides into her wet pussy, making love to her as she moans softly, her body convulsing with pleasure.
