A new frontier in sports testing, Hoshino Riko dazzles! Her naked body challenging the limits shines with unparalleled beauty under natural light. The moment capturing muscle contractions is truly the essence of sports. The sunburn she showed at the end of the shoot enhances the vividness and beauty. The expression on her face, teetering between fatigue and pleasure, is exquisite, making it a fantastic project that every muscular actress would want to take part in.
