The sprinter Maharahara Miku, whose F-cup breasts are the talk of the town for swaying too much, is making her AV debut! As a student, she had a brilliant record in the 100m sprint race at the national championships. Now that she's 22, she's a member of a certain corporate track and field team and practices every day. Although she loves her current boyfriend, she's not satisfied with her abundant physical strength and well-trained body, so after much deliberation, she decided to appear in this video! Her bouncy body and beautiful big breasts move in the air and her masochistic nature blossoms in the release of her lively performance!
