Three street fashion girls named Yui, Mio, and Riko were checking out flyers when they decided to visit the recently opened martial arts gym offering free self-defense experiences. As they learned about maintaining composure even under pressure, their instructor suddenly began using wrestling holds to make them cum against their will. Despite trying not to show any expression, they couldn't help but moan and squirt all over the place. Embarrassed beyond belief, he then inserted a vibrator inside each of them while holding them down in various positions. Their pussies clenched tight around his cock as he roughly fucked them, causing intense orgasms that left them shaking uncontrollably. "Stop teasing us! Make us feel it!" they cried out in desperation.
