Erotic use of JBL

Have any one used a JBL with their BF/GF in the following manner? Receiver is seated on JBL and giver sits straddled on receiver and begins making out with each other as the valve is opened and the receiver is filled?

Not for real, but this is my routine fantasy every time I use my JBL.

While seated on a JBL, which is atop an examination table, my partner stands between my legs and keeps my mind occupied by kissing and stroking my penis and testicles. when I get to the "I really need to get up phase" she switches to oral play. It works very well.

Yes. I was blindfolded and led to the center of the dungeon. The JBL was completely filled and placed on a wooden chair. I was seated on the JBL and tied to the chair, hand/arms behind my back with no leverage to lift my torso, knees spread and ankles tied to the outside of the chair legs. The JBL valve was opened, then my sub was ordered to suck me for a short while, then face me, straddle my hips and sit on my lap. My own weight, plus the additional weight, accelerated the injection from the JBL and measurably increased the volume injected.
