We ended up having quite the predicament day, myself and my Dom but being sub/sub to two amazing Dommes. I think I'm still recovering two days later (and yes, still have lovely cane marks!).
I'll share one scenario with you involving an enema and a Sybian. He was tied to the cross facing outward with his hands in leather sleeves above his head and feet tied apart. He wore a leather mask that she let him see out of - but only periodically. A VERY large 6 L bag was filled and hung above his head.
I was told to sit on the Sybian that was located directly in front of his cock. The Sybian was fitted with a very thick cock, which took me a few impalements to adjust to. The ridged pad was located in front of my pussy just on my clit, if I was leaning forward and pressing hard it could not be ignored.
His Domme thrust a number of larger nozzles into his ass and started the flow. The other Domme was in control of my Sybian settings. Vibrate/fuck mode and rotate modes. He would get enema flow and be forced to watch me (or hear me if the mask was made to blindfold) while my settings were controlled by my Domme. She would get me close and then decrease the Sybian (how evil!) just as I wanted to cum. If I wanted more, he had to take more enema. If I had cum enough it might stop - but if I was begging mercy from forced cumming his Domme would ask him if I should be forced to endure more for less of his enema. Then she would consider turning down his flow while I writhed on the Sybian.
My settings started out hot, then were quickly increased and there was NO stopping an orgasm HARD. His cock was at my mouth level and dripping onto the floor as he took his enema, listening to me scream and cum. Domme then insisted that I lean forward and suck his cock - which forced my clit onto the Sybian and made for more forced orgasms. Occasionally I would lean back and look at him, SO hot, taking his enema for me while I came. And came. Eventually he had satisfied his Domme with enema and I was limp and trembling from cumming. Very hot scene!
Then there was the competitive electro play, the "Y" seltzer enema, the two way nozzle and more......what a weekend!!
