Former national-level athlete Ukawa Ruru returns for her second exclusive release. With limited sexual experience, she is put through a punishing 24-hour orgasm-training camp packed with nonstop pounding. She is penetrated the moment she reaches the lodge, then ambushed again in the bath, while sleeping, and as soon as she wakes. Her powerful G-cup body trembles and arches under intense deep pounding she has never experienced before, leading to her first squirting orgasm. After being made to cum around the clock, the once-composed athlete is left completely overwhelmed and spent.
