She struggles as you intended to never let her out of her Musky chamber. Every time you Erected a large blast of air hit her in the face as the Cum churns around her. It didn't Digest her but she Screams and Kicks, It goes on for Days until eventually her struggling had came to a complete halt. She had accepted her Fate as a Bulge in your Balls. She eventually found it rather Erotic to be trapped inside you, And every morning since then you'd hear Moaning and you'd feel her Wiggling, Your balls Vibrate as she Screams and Kicks from orgasm. She was your Ball pet for the rest of her life.
