Haruka Sanada recently took up swimming, so she asks an acquaintance who used to be on a swim team for a few pointers. Rather than settling for a quick chat in her room, she puts on a skin-tight competition swimsuit and practices swimming motions and stretches on the bed. As Haruka eagerly moves closer, their arousal builds until the swimming lesson turns into a sex lesson. He pulls her swimsuit aside and fucks her without taking it off, putting her spectacularly thick, curvy body on full display for competition-swimsuit fans.
