Wow, finally found it! Recently popular among men—the "Hula Dance Class." Among these, the standout is the incredibly well-shaped instructor, whose hip movements are unbelievably sexy and irresistible. I sneaked in and immediately started rubbing my crotch against the lightly dressed teacher, wriggling together with her. Students who couldn't keep up were forced to stay after class for extra practice—and during one session, she unexpectedly performed a hula dance completely naked! After finally succeeding, I ended up alone with the teacher. I mounted her in cowgirl position, thrusting my hips and penetrating her, ultimately unable to resist cumming inside her.
