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 and again, while laughing at his panic. Isn't bath time the best?
