Miu lets out intense moaning sounds during yoga, ones she can't normally make at home. Inserting a vibrator into her pussy and thrusting it deep into her anus, she can't hold back the pleasure, crying out, "Ah~ No, I'm gonna come~!" Waves of pleasure surge from both of her vibrating holes, gradually transforming into an enormous cock. At that moment, Miu's voice overflows with pure ecstasy.
