I was well aware of how much time had elapsed and I just wanted them to get on with it.

Inspiration! Genius! He drew back, fighting the instinct to push forward. The glans of his penis flared out on withdrawal. Like piston rings in a cylinder bore they created a near perfect vacuum and gently sucked her cervix down her birth canal. There are some receptors that respond to just that action. May exhaled heavily and gasped unintelligibly in Chinese, translating to "Oh my GOD!!" as she grasped at his bum and pulled him forward as if to say "Play it again, Sam." (Sorry Humphrey). The rhythm quickly established, like the piston of a steam engine reciprocating within the cylinder, May's finger tips being the control rods. Here a diminutive Chinese woman was working a very big man with the lightest of touch. Her exhalation the exhaust steam. An amazing sight.

Jeff had returned with Flora and she was captivated by her lover dancing on the finger tips of my wife, in the horizontal folk dance that is. Jeff and I were positioned either side of the couple and Flora behind. Jeff fondled May's nipple, I did the same, but we unobtrusively gave them space, physical and emotional, to be where they needed to be. Flora was cupping her lover's balls.

The tempo was increasing, such was the pleasure each withdrawal was generating. This was inverse fucking. The pleasure came in a sucking, tidal wave on the down stroke. May was tensing, as was Mark. Her heels dug in behind his knees and she nearly stood up on then with every up stroke only to squirm in total abandonment sinking back on the mattress as he rocked backwards. The words failed, only exhalations now. Mark did not fear losing his place, his cock was trapped in her cunt, and his knob was too big to slide out in its engorged state. As he went for it they had three supporters silently urging them on.

"He's cumming." Flora startled us. "I can feel him cumming". There was a subtle twitch in his perineum, an indication of the mixing of his sperm from his balls and the fluid from his prostate which would carry them on their suicidal journey in about 17 seconds time.

I wanted to break into the momentum and ask May if she was physically and emotionally prepared for what was imminent, but I didn't. I didn't want to break the spell and I knew what her answer would be, accompanied by a string of Chinese invective. It is a great thing to know a partner so well! However I did slide my hand down between them, not hard to do as Mark was now raised up positioning himself for the vinegar strokes. I bore down on her belly, and lordy, lordy I could feel the bulge of his cock plugging her. "Far fuck'n out, mate. Far fuck'n out! Once in a lifetime." I could tell people later.

Mark made a surprising move. He lifted May clear of the bed and passed his hand further around behind her and desperately sought her arsehole. Normally this would be a game finisher; she was ever so prudish about anal stimulation. Instead, in the bath of lubricant, sex fluids and sweat he found her ring pulsing, bearing down and opening like a sea anemone. A gentle push and his finger was welcomed inside with relish, protruding only a centimetre or two into that prudishly personal space. That action alone precipitated a simultaneous orgasm. The rectal wall is barely more than skin thick and Mark could feel his own shaft as through he had it in his hand, bulky and veined, but slowly subsiding from its former glory. It is also richly endowed with nerve endings. The pleasure that rocketed through May's body tipped her over the edge.

Words alone cannot do justice to what occurred in that room, they were with us in body but on another experiential plane. More than ecstasy, it was an interplay of passion, lust, primal urges and sheer bloody sexual pleasure. A wave of pleasure in one triggered an equal and opposite response in the other. The senses not in play were the eyes, and spatial awareness. I was studying both contorted faces. Their eyes when open, were glazed, non seeing, their ears tuned only to the groans and obscenities the other uttered. To them we were not in the room although Flora was pumping Mark's balls, Jeff was busy keeping May's vaginal lips open, and stopping Mark's cock from bending. I had the best job of all, I was pressing my palm down into May's belly to feel the fullness in her vagina, and to ready myself for the spasms to come.

Those obscenities were largely irrelevant to us, "fuck me, fuck me..." from May, "Fuck, you horney little bitch, take my cock!!" emphasis on COCK. That final thrust made May's eyes open in wonderment as she slumped back, her hand joining mine on her abdomen. Together, hand on hand, we enjoyed the mutual orgasm, the throbbing, pulsing, life giving force jerking deep inside her. Nothing spectacular, voluble or violent happened. I could feel the motion of her womb bobbing to the jellyfish like opening and closing of Mark's glans penis as he pumped his spunk into her. The same primal precursor that put us all in that room. May was experiencing an orgasm so intense that it was barely noticeable for it was in her soul, not her body. Her hand on mine drummed the beat.
