While you schtripped, Nikki held onto her head in an effort to keep it in one place. When you were down to just your chastity belt, she demanded "DANCE!"
There was no music on, so you did your best to improvise. You felt like a fool, but at least she was unlikely to remember this in the morning.
Nikki was beginning to move a little bit too. You weren't sure if she was dancing, or falling. But soon you had your answer and she dropped on her hands and one knee on the couch.
