parathd-04458 A highly energetic college sportswoman loses control during a mat health training session and ends up with an internal finish (4) Usui Serina

A sporty female college student comes to a mat health shop for training. During the manager’s hands-on instruction, she gets carried away and unexpectedly begs for more, then ignores the manager’s attempts to stop her and takes the lead herself.

Serina, 22, visits the shop. She is said to have an estimated H-cup figure and stands over 170 cm tall. At university, she belongs to the volleyball club. She is a beautiful woman with refined features and an eye-catching figure.

During the practical lesson, she shows off dynamic mat play that makes use of her impressive proportions. However, she becomes so excited during the session that she decides to take the initiative herself, even if it means risking disqualification. Her energetic, bold performance is highly engaging.
