Kayla moaned quietly to herself and moved her leg carefully, trying to keep his cock inside her.
"Mmmm .... ohmigod that was absolutely fantastic .... I can't believe how wonderful that was Peter! Oh wow, I can't remember ever coming like that!"
There was silence for a moment and then Peter responded,
"I can't say I have either Kayla. That was a long time coming and well overdue -- no pun intended on either count I may add." He laughed quietly and began to gently withdraw his now wilting cock.
"I wondered how long it might be before you two got it together ..........?"
Jake was standing in the doorway and neither of them had heard him come in.
Kayla went sheet white in shock and tried to speak; but she realised there was nothing to say which could possibly explain their nakedness - or indeed, anything else to do with the situation.
She thus stayed silent as Jake continued in a hesitant voice, uttering words he was far from certain he wanted to say.
"I had a feeling you, er fancied Peter my darling .... and unless I'm mistaken, I'm pretty certain it's been .... um ....mutual. From where I'm standing, I reckon Peter's ... erm, how do I put this .... always had the hots for you ever since he first met us ... or am I wrong there my friend?"
Peter immediately sympathized with how Jake felt and understood that he wanted to direct things his own way now - so he went along with what had been said by turning his head to nod and murmer a wordless assent.
Beneath it though, he had little interest for the moment in their stilted conversation. He was far more interested in his current physical reactions - for, still with only the head of his cock just inside Kayla, he could feel his erection beginning to rise again, spurred on by the eroticism of the situation.
Rather than continue his initial move to withdraw, he now pushed imperceptibly forward and began to re-enter Kayla's beautifully warm and tight body. He felt her react to the movement as her vaginal muscles twitched against him and sucked him further in.

"You don't seem .... erm, particularly outraged by this Jake." He mumbled slowly, his eyes half shut in the pleasure he was feeling from being inside Kayla again.
But the sensation was all too much and before waiting for a response, his lust took over, irrespective of Jake's close physical presence.
He threw caution to the winds and renewed his hold on both deliciously firm globes of Kayla's ass. He slowly but purposefully drew her back towards him until she was sliding further and further onto his cock - as if by doing so, he was challenging Jake to draw a stop to it all. The cheeks of her ass felt fantastic as they pushed against the front of his hips.
Jake watched with the fascination of a rabbit in headlights - the large tent in front of his trousers giving incontrovertible evidence of his deep arousal. At this stage, he could not have stopped what was happening before him even if he'd wanted to.
It had been exciting enough to watch their first coupling from his position outside the bedroom window; but now it was happening inches in front of him and his arousal was such that even if he just touched himself at this point, he knew he'd start off a violent orgasm.
There was his beautiful young wife on her knees, with their friend holding her from behind with both hands gripping that wonderful firm ass as he pulled her onto his erection. He was about to rut her again like an animal and the sight fulfilled every fantasy Jake had ever dreamed about. He wanted to watch it through to the end, frightened that he might suddenly wake up from the most erotic dream he'd ever had.
As he felt the wonderful tight softness of Kayla's sex enveloping his growing erection, Peter went on haltingly,
"It looks as if ..... well .... I er .... think you must .... um .... you must actually quite like the idea of me having Kayla .... is that ... right Jake?"
He'd given Jake the opening to take things further without divulging their earlier plotting; but Jake didn't respond and there was a slightly awkward silence for a minute while Peter's renewed intrusion slowly continued and eventually he stopped when half-way into his friend's wife. Without further effort on his part though, he felt her muscles continue to draw in his willing penis until finally, he found himself buried deep inside her once more.
He had great difficulty controlling a natural urge to start thrusting in earnest and couldn't help a small moan of ecstasy at feeling the end of his cock being milked by the involuntarily spasms of Kayla's muscles.
Having violently come only a short while before, Peter was surprised to find that despite his age, he was now fully erect again inside his friend's young wife. His member twitched in reaction to her movements and closing his eyes once more, he gave himself up to the amazing feelings which her body was creating for him. He decided to leave things to Jake.
Slightly unsure how to handle this situation, Jake moved to sit on the sofa beside Kayla's head. His wife's face was deeply flushed - partially through shock at being discovered and partly as a result of the irresistible feelings of deep pleasure which were once again beginning to take control of her mind and body.
Jake recognized only too well the look of growing bliss on Kayla's face and was still amazed that instead of feeling deeply jealous, he really was experiencing a wholly different series of emotions.
On the one hand, he was surprisingly at ease with the situation and what was more, he'd developed a novel sense of pleasure that his wife appeared to derive such obvious delight at the ministrations of an older friend. Jake felt he should somehow participate and help to enhance her enjoyment - both for his own erotic pleasure as well as for hers - but he was at a loss to know how.
Underneath though, he knew there were still residual pangs of anxiety lest he had gone too far by allowing it all to happen in the first place; and he wasn't too sure how to address them. But then again, things had almost certainly progressed too far now to draw a halt without causing a great deal more trouble - and knowledge of his helplessness enabled him to cast aside his fears and indulge the situation to the full whilst he could.
He was hugely excited by the deeply erotic element of voyeuristically watching his wife's oh so willing penetration by another man; and his own cock erected to its fullest height at the fascinatingly pornographic sight of Kayla now completely impaled again and sensuously writhing back onto the hard penis of another man behind her.
Jake looked lovingly at his young wife for some minutes - during which she had her eyes closed in obvious pleasure. Her head was lying sideways on the sofa seat as her body moved in time with Peter's penetration. Eventually, he reached down to kiss her softly on the lips, his tongue gently probing at his wife's mouth as if tentatively seeking her reassurance that she still loved him.
