Excerpt:

...She had no idea that he was there. Had she known, it was doubtful that she'd have cared.

Diego ignored the pain seeping between his vertebrae. Crouching like a repentant sinner seeking the absolution of anointment from above, he peered out at them from inside the bedroom closet belonging to him and his lover. His eyes burned like forested bonfires in the night.

She was within seconds of coming again. Behind her, the powerhouse with the bodybuilder's physique, confident stoker of snug pink furnaces that burned all the hotter when treachery was their fuel, battered pleading squeaks and whines from bedsprings and woman alike. Diego's throbbing heart sought to shatter his rib cage. The bitch was having the time of her life.

"Okay," she gasped, "okay, okay, okay okay okay!"

Woven into him, into his network of brown hands as covetous as callous, and as large as excavator buckets, she looked so small and breakable that pity tested Diego's heart the way a burglar tries the window of a stranger's home. Her lover was a rack and pinion molestation of corrugated copper abs, glossy, carbon-hued veins, lunging steel-belted sinews that roamed everywhere in and on her at once. Wetwired into her illicit lover, she collapsed onto her elbows, head lolling, his kinetic energy shaking her apart.

"Okay, what?" her fuck machine demanded, laying a smack upon her right asscheek that elicited a shocked yip of only marginal objection. He reached beneath her. Calipers of thumb and forefinger found rubbery nipples, adjusted pitch frequency of feminine moans, modulated sensations until she hyperventilated. Diego watched, strangely fascinated at his beloved's surrendered humanity.

"Oh God, Barry, wreck it. Wreck me, baby," she urged.

"Bullshit," the fuck machine replied, "Wreck yourself."

"Baby!" she whined.

"Uh-uh. First two 'gasms were free. Better use those hips and do some work if you want anymore."

The fuck machine punctuated the demand by stopping, its pivot joints crawling to a halt, immobilizing the thrusting hips and cock that were her drug of choice tonight. Diego held his breath and waited. His mind's ear could faintly hear the machine's internal gears slow down and stop. The heat radiating from the two of them threatened to blister his skin as sweat, pungent and syrupy as engine coolant, dripped from Barry's chest and chin. All but an inch of his impressiveness withdrawn from her, not to be moved either literally or figuratively, Barry knelt awaiting her choice.

And, effecting a level of obedience that Diego had never enjoyed, she tilted her pelvis backward, impaling herself upon Barry's welcomed intrusion. Bracing herself upon arms and knees, she leaned forward slowly and fell back a second time, and then a third, her force of motion mounting. Diego's blood turned to bile.

As she found her rhythm.

And became the machine...
