Romantic and Frightening

Once in a while I allow my sub to serve me while in the tub.  I can easily fantasize that he's someone else when he's massaging me from behind, and I can also do bad things to him while he's in the water.  I enjoy smothering him underwater with my ass and feet while watching the water level rise.  Seeing him suffer and struggle for oxygen is fun to say the least.  I wrap my strong legs around his neck and squeeze hard taking his breath away again again while laughing at his panic. Isn't bath time the best?
