Master opens a drawer and takes out a large black butt plug. He squeezes some lube onto
the plug and begins inserting it into Cindy’s tight asshole. Cindy flinches and moans.
“The Slave will behave!” Master commands. Cindy tries to relax her muscles. “Breathe, my
Slave. Deep breaths. You will thank me for teaching you how to take it in your ass.” 
Cindy pants and grits her teeth and tries to calm herself. Master slowly twists and giant
probe into her. I stare intently, wishing I could help the other slave. I also wish it was
my ass that was being poked. 
Finally, the butt plug pops into Cindy’s hole. Master holds it in firmly. “Keep those
cheeks tight. Do not let this slip out,” Master demands.
After he is confident the butt plug is firmly in place, Master walks over to his wall of
toys and picks up two strap whips. Like a professional whip-cracker, Master begins
swirling the strap whips in the air. Then he brings the whips closer to our skin. I can
feel the cool wind from the whips over my breasts. The straps begin stinging our nipples.
I flinch slightly and Master waves my whip faster as a punishment for moving. The whips
swirl around our navel…over our feet…on top of our thighs. I love the cool sting. Master
stops for just a moment and takes aim between our legs. With one big windup, Master
crashes each whip down right on our pussies. In unison, Cindy and I moan and lift our hips
up – a not-so-subtle way to ask for more. Master obliges, whipping our wet snatches over
and over. Cindy is bucking so wildly that she must be coming. The scent of pussy juice
fills the air.   
Master throws down his whips and grabs the sides of my sex swing. Then he inserts his
penis in me and begins rocking the swing in time with his thrusts. My Master is fucking
me! I can feel every inch – every millimeter -- of his cock. I have just gone to slave
heaven. The fucking and the rocking and the swinging seem to last forever. For a moment I
glance over to Cindy, who is enjoying the show, her eyes affixed to Master’s snake probing
my hole. I can tell Cindy wants some, too. I close my eyes and lose myself in ecstasy.
Swinging…fucking…swinging…fucking…
