I am sure that because of the unusual circumstances the girls had suddenly found themselves in, that it had a lot to do with what happened next. Though I also believe, the encouragement they were also given by both Jack and I as we sat there had a lot to do with it in addition to that.
There was very little that Darlene and I hadn't shared or discussed with one another over the course of time. Most of it had been private, sometimes decadent fantasies, curiosities, or desires we'd been more than comfortable in sharing with one another. One of mine of course had been seeing Darlene with another woman. Something she wasn't adverse to, not by a long shot as she'd professed what I felt to be a natural curiosity about that herself. Darlene had shared with me one or two situations where she'd "sort of" fooled around with another woman prior to our being married several years ago, but beyond that, hadn't ever really done anything. Especially either going down on, or having another woman ever going down on her. I could only assume from the little we had learned about Jack and Beverly, that she had even less experience in that regard than Darlene had had. But that too could have simply been because she'd never revealed it, or would admit to it even if she had.
Mattie was the first to stir, and upon doing so, had run her hand down the inside of my wife's long slender thigh, down to her knee and back up again. I heard her sigh pleasurably as Mattie did this, sitting up just slightly in order to look over in my direction. With Jack still sitting in one chair, and I the other, I gave her our already talked about "signal" merely smiling with a simple nod of my head as she looked over towards me. She smiled back, and then lay down on her back once again as Mattie too had seen the non-verbal approval given between the two of us. She then smiled at me, rolled, and immediately began to softly run her tongue up Darlene's legs doing what her hands had been doing only moments before. Sensing movement, Beverly opened her eyes, rolling onto her side now watching as Mattie continued the soft flirting tease up my wife's legs moving ever closer to the puffy very swollen lips of her split. Looking over towards her husband, Jack sat grinning, his hand slow-stroking his cock back to another hard stiff erection. Perhaps they had their own signals, or maybe it was simply seeing his hard prick standing up again that caused her to lean over, placing one of her hands around my wife's breast, cupping it, and then lowering her mouth to surround the firm erect nipple, sucking it in as she did so.
Once again Darlene sighed pleasurably, her arm coming up and around Beverly's bare back, caressing her with finger tickles as she lay tonguing, and flicking Darlene's hard stiff little tit tips.
I had felt my own cock suddenly lurch with renewed interest, taking a brief quick glance over towards Jack as he sat there fisting himself, firmly erect now, obviously very aroused at what he was seeing. I couldn't blame him in the least, now enjoying the feel of my own cock in hand, watching Mattie as she just then allowed her tongue to snake out, finding the sweet little pea of pleasure between my wife's legs. Darlene groaned, arched her back, and literally lifted her ass off the bed briefly in response to that.
"Damn!" Jack moaned excitedly. And again, I couldn't blame him, smiling in agreement, feeling a bit of lubrication suddenly leaking out the head of my dick as the two of us continued watching in pleasured amusement, jerking ourselves off.
Mattie was really going at my wife's pussy now, her fingers had wormed their way inside, slowly fingering, tickling, and teasing her just as her tongue was doing. I had seen my wife reach out gripping the sheets within her fist in one hand, and all but digging her fingers into Beverly's back with the other as she continued to lavish quick flicking tongue licks against my wife's nipples, alternating back and forth between her breasts, paying homage to each as she did. Hearing her begin to pant a short time later was a sure sign she was rapidly approaching climax. Sensing this, both girls seemed to increase their ministrations and caresses of her body, hands seemed to be everywhere at once, lips and tongues as well, kissing, sucking, flicking licking, driving Darlene wildly insane as she began to writhe in ecstasy between the two women.
"Oh my God!" Darlene finally exploded, once again arching her back, pulling the sheets with her as she hung there for a moment almost as though suspended on wires as she somehow unbelievingly held that particular pose. Even Mattie had been forced to come up to her knees, her hands suddenly running beneath my wife's ass, helping to hold her there as she pulled deeply on Darlene's clit, sucking it for all she was worth, just as Beverly was now doing to her right breast, her other hand pinching quite fiercely her mouth neglected nipple. "Holy fuck!" Darlene screamed then, her orgasm suddenly overwhelming her, the next sounds out of her mouth holy unintelligible as she ran them all together, hissing out her pleasure before shuddering back in a near convulsive fit back onto the bed.
I hadn't even realized it until that very moment. I'd been stroking my dick, pumping it harder and faster the closer Darlene got to climax, when she came, I felt the first pleasured spurt of my own cock joining her climax, the spunk leaping from my prick tip to land somewhere near my feet, though I only realized that I was even spunking upon feeling it, too engrossed in the unbelievable scene that I'd just witnessed to at first even realize I'd just climaxed myself.
I had learned long ago, the harder Darlene came, the more sensitive she became as well, her hand letting go of the sheet as she ran it down between her legs, protectively covering herself against the continued onslaught of Mattie's still lightly flicking tongue. Her delightful, sensual giggles giving further evidence to her pleasure, the giddiness of her high infective causing both Mattie as well as Beverly to giggle along with her.
"Now...it's your turn!" Mattie said moving over to place herself between Beverly's legs. I noticed there was no additional look from her back towards Jack, she simply fell onto her back, her legs just happening to be bent at the knee as she did, Mattie using them to even more decadently spread her, revealing the very wet, very slippery swollen pink folds of her sex.
Unlike my wife's totally bare, and smoothly shaved pussy, Beverly still had a bit of neatly, closely cropped and trimmed pubic hair. It wasn't dark, though neither was it blonde, a sort of very light brown, even sparse triangle just sitting above that wet looking slit. Just as she had done to my wife, Mattie now did to Beverly, easily locating her hard little nubbin, flicking out at it with her tongue, vibrating it like a tiny little finger.
It was odd to see and then hear the reversal of roles between my wife and her. Darlene was always generally very vocal, but she'd seemingly lost her ability to speak until actually reaching orgasm. Beverly had said or exclaimed very little all evening, far more reserved and shy in nature, with only occasional bouts of boldness and brashness escaping her lips. Not now however, as Mattie drew her precious little clit inside her mouth and began gently sucking it, Beverly unleashed a diatribe of wickedly erotic feelings that were easily heard by all of us, not to mention whoever might have been on either side of us, or even outside walking by in the hall!
"Oh my God yes! Suck my fucking clit!" she literally screamed out at the top of her lungs. I looked over, saw the very surprised expression on Jack's face, though his smile was again about as wide as it had been all evening, if not more so as Beverly continued to express herself emotionally. "Stick your fingers in me please!" she wailed loudly as well. "Fuck my cunt with them, fuck me, eat me, suck me!" she screamed out over and over and over again.
I watched as Jack finally stood up, weak in the knees as he wobbled towards the bed. Mattie looked up, saw his approach, smiling, yet still flicking her tongue out at Beverly's clit. When Jack was close enough, she reached out, her hand now grasping his prick, drawing him onto the bed alongside her. She took over for him then, jacking his cock, her tongue still furiously working Beverly's pussy as Darlene's hands now began molding, fondling, and hotly caressing each of Beverly's sweet tender looking breasts.
Jack's deep grumbling moan announced the arrival of his pleasures, his prick suddenly leaping in response, the first spurt of his fluids rushing out in a torrent, Mattie holding onto, still jacking his cock, though now aiming it directly at Beverly's cunt. Fascinated, I had stood coming over to watch this myself, watching his cream as it poured from his prick splashing against his wife's pussy, Mattie now licking his spunk at the same time she continued licking his wife's precious cunt. Beverly's screams of rapturous joy filled the air, along with the sound of pleasured giggles and chuckles coming through the wall in the next room as she did so.
Long after Jack had collapsed down onto the bed, thoroughly spent, Mattie lay between her legs, softly licking her, lapping up Jack's glistening white spunk, savoring the combined taste of each. It was erotic as hell to watch her as she did this, amazed at myself now as my somewhat flaccid prick once again began to make an appearance.
"Wow!" Beverly eventually managed. "That was...incredible!"
