Scuba underwater breathing

Description: Today i try something new, which despite my experience with scuba, i find quite disconcerting.  i set up my scuba tank and regulator as directed by you and get in the bath.  i put on my scuba mask and lay down flat in the bath and begin to fill it.  as the water slowly envelops my face i feel very much under your control, as you are the one who is in control of my air!  watch close- up as the water rises above my head, submerging my face in the water as i breathe entirely from my scuba regulator.  as directed by you, i masturbate on command, play with my breasts as per your orders and control my breathing with slow, deep breaths underwater.  i found the whole experience quite unnerving!  if you have a scuba and underwater fetish, this scene is for you!
