I still remember the moment when it all began. I had just come out of the den when I spotted my wife Lilith looking very intently out of our back window.

I was about to say something when I noticed that she was rubbing her pussy through her dress.

Curious as to what had gotten her so aroused, I slipped back into the den and looked out the window there. All I could see, aside from trees and houses, was Theo, the oldest son of the family who lived next door. He was mowing their back lawn, wearing only a pair of shorts, which showed off his tanned, well-muscled body. It must have been the sight of that body that had gotten Lilith all heated up. Which surprised me, because while my wife was 55 at the time, Theo was only 19!

I couldn’t help wondering if this was just a one-time occurrence, or if it said something about my wife’s taste in general. I said nothing to Lilith, but I decided to experiment a little to see what would happen. Over the next few weeks I took her out to a number of places frequented by the younger crowd. While she was not blatant about it, I often noticed her eyes straying to guys in their early 20s, or even younger. When we went to a nearby park one hot day, she was practically drooling over a bunch of young guys who were horsing around without their shirts on.

When I finally confronted Lilith about this, she denied it at first, but eventually broke down and confessed. She said that one of her married friends had hooked up with a 20-year-old guy, and had told her that the sex was really fantastic. That had started Lilith thinking about it, and she couldn’t help wondering what it would be like to be in the sack with a virile young stud. I then asked her if she wanted to try it for real and find out. She scoffed at the notion, saying that she loved only me, and adding that no young guy would want someone as old as she was in any case.

Now I totally believed the first statement, but the second was absurd. Lilith has always been what you would call a voluptuous woman, with very large tits and a full derrière to go along with it. Men had checked her out her entire life, and still did. There was no way any guy wouldn’t want a ride with her, at any age.

I could tell that, despite her protests, Lilith was turned on by the idea, so I decided to go ahead and make it a reality. Actually, the thought of seeing her fucked by another guy had always been a fantasy of mine. As far as I was concerned, it was one that was long overdue to become reality.

I began to implement my plan a few days later, at a large summer pool party thrown by some neighbors who lived down the street. They held it every year and invited the entire neighborhood, so it was always a huge affair. Theo was a regular attendee, and I figured that if I could get him alone, I could find out if he might be interested in making it with my wife.

To help things along, I had purchased a special one-piece bathing suit for Lilith to wear at the party. It was quite snug and dipped low in the front. When I showed it to her, she was a bit shocked to see how much it revealed, but when I told her I would be turned on by her showing off her magnificent rack, she agreed. I knew that with that ample cleavage on display, she would definitely be attracting a lot of attention.

The party was crowded, as usual. Lilith had a few drinks, which always makes her both horny and amicable to suggestion. After a time I tracked Theo down and managed to get him alone. I pretended to be a little drunker than I was, and at one point I asked him what he thought of the new swimsuit I had purchased for Lilith, who just then was wading at the shallow end of the pool. Theo ogled her for a minute before saying that he liked it a lot.

I then took things further by going on about my wife’s big tits, and how much I loved them. When I asked him what he thought, he said he had to agree that they did look great. I then dropped the bomb on him, saying that my wife was into younger guys, and that he in particular really turned her on. You should have seen the look of shock on his face. As he stared at me like a deer in the headlights, I went on to ask him if he would like a shot at her. His reply was stammered and inarticulate, but there was no doubt that he was saying yes.

I then told him to stay where he was while I talked to my wife. If she was ready, I would give him a signal, and then he could get into the pool and play with her underwater — though I warned him not to go so far as to attract attention. He nodded eagerly, and I walked around the pool, motioning to Lilith to move over to the edge so we could talk.

Bending down so that no one could overhear us, I asked Lilith if she was ready for something a little risqué. She asked me what I meant, but I could see she was interested. I told her to wait where she was, and she would get a surprise. I then signaled surreptitiously to Theo, who quickly got into the pool and headed toward my wife.

Her eyes were still focused on me, wondering what I was up to, as Theo moved up behind her and evidently did something that made her jump. She stared at him in shock, then turned back to me. I raised the glass I was holding and smiled at her, letting her know that I had set this up. Her eyes were still wide with surprise, but after a minute her eyelids started to droop and she got a kind of faraway look, which told me she was starting to enjoy whatever it was Theo was doing to her under the water.

From a distance it looked as though they were just talking, and luckily no one was close enough to see  what was actually going on. After a few minutes of this submerged play I saw Lilith draw her breath sharply, and then shudder with what I recognized as a climax. A moment later Theo moved away from her and got out of the pool.

I had been seriously turned on by what I had witnessed, and I knew I wanted more. A lot more. I caught up to Theo, who thanked me profusely for letting him have fun with my wife. When I asked him if he wanted to go even further, he said he was all for it.

I then asked him if he knew any other guys around his age in the neighborhood, who might also like to make it with Lilith — and who also knew how to keep their mouths shut, as we didn’t want this to become common knowledge. Theo thought about this for a few moments. Finally he said he knew lots of guys who would probably love to nail my wife, but he had three particular friends who could be relied on not to breathe a word to anyone. Two of them, Ray and Keith, were Theo’s age, while the third, Norman, was only 18. They were all at the party, and when Theo pointed them out to me I saw that they were all Lilith’s type — meaning good-looking and barely legal.

I then handed him a key to our place, and told him to round up his friends, go to our house and wait in the living room, so that my dear spouse could receive the surprise of her life when we got there. He snatched the key and hurried off on his task.

I then went to join Lilith, who was still in the pool. She told me I had been a naughty boy for surprising her like that, but she also thanked me for letting it happen. I could barely keep from blurting out what else I had in store for her, but I really wanted to see the look of surprise on her face when she found out, so I said nothing.

We hung out at the party for a while longer before I told Lilith we’d better get going. She changed into a more appropriate outfit, and we walked back to our home. Since Theo had my key, I told Lilith I had left it at home, and used hers to open the door.

As we entered the house, I informed my wife that I had another surprise for her, and led her into the living room. She obviously couldn’t believe her eyes when she spotted her four young suitors, all smiling in anticipation of what was to come.

Lilith looked at me in shock, and her eyes were wide as she whispered, “All of them?”

“Why not?” I replied. “After all, you wanted some younger cock, and if one is good, how much better will four be?”

My wife did not argue with that reasoning.

I then motioned to the guys to come over and help themselves to my voluptuous wife, which they were all most eager to do. She gasped as their hands went all over, feeling her up through her clothing, which they soon started removing, one piece at a time. When her bra came off they gazed in fascination at her tits, proclaiming them much bigger than they had thought. They manhandled them almost roughly, though Lilith made no objection to that. She seemed to be enjoying the very physical treatment her body was receiving.

Soon her skirt and panties were gone as well, leaving her totally naked. Theo then instructed Norman to grab some cushions from the couch and throw them on the floor for Lilith to lie on. After easing her down onto her back, the guys quickly shed their clothing, showing off a quartet of rock-hard cocks, standing at attention and ready to go.

Theo was first in line, and to my surprise he wasn’t gentle at all as he positioned the bulbous head of his manhood at Lilith’s entrance, and proceeded to shove in nearly half his length with one stroke. My wife cried out at the sudden intrusion, and I was about to tell him to take it easy when she cut me off, moaning for him to give her more. He drew back a bit, then plunged forward, burying all but the last couple of inches of his dick in her twat. Her body jerked, but she still cried for more, and one more thrust was all it took for his entire cock to be buried to the hilt inside her.

Theo’s cock was about the same size as mine, but it usually took me at least a minute to get all the way inside my wife, whereas Theo had managed it in a few seconds, and Lilith’s lustful reaction now had me wondering if I should perhaps have been a more forceful lover.

Theo now began working his cock in and out of my wife’s snug pussy, slowly at first but still powerfully, and rapidly picking up his pace. Lilith was groaning and whimpering with pleasure, and then she suddenly cried out as a convulsion shook her body. I had never known her to come so quickly, and as far as I could tell her orgasm was as intense as any I had ever given her.

With that the other guys began to cheer Theo on, urging him to give it to her good and make her come again. Theo responded to their encouragement by pounding her still harder, her big tits bouncing all over the place while the room filled with the sounds of flesh smacking against flesh. This caused the guys to shout louder, and Theo to go at her even more furiously. “Yes!” Lilith cried out now. “Yes! Oh God yes!” And then she climaxed again, harder than before, her naked body spasming uncontrollably.

Theo was now losing his own control, and he gasped out that he was going to fill my wife with his come. To my delight, Lilith begged him loudly to do just that, and a moment later he pushed himself deep inside her as he released blast after blast of his seed into my wife’s eager snatch. Finally he was finished, and he high-fived his friends as he pulled out of her.

Ray went next, but before going into her he asked Keith and Norman to each grab one of Lilith’s ankles and spread her legs for him. I could see Theo’s sperm dripping from her used pussy as she was splayed wide. It was as though she was a tribute being offered up to Ray’s youthful lust, a prize he was obviously eager to claim.

Stretched out as she was, Ray was able to move right in and hammer away at my moaning wife as if there was no tomorrow. Soon he started talking dirty, telling her that she was a horny slut, that he and his buddies were going to nail her pussy until she couldn’t stand up, that they would fill her with so much sperm she’d slosh around as she walked, and so on. To my surprise my wife answered him with language just as raunchy, agreeing that she was a slut and telling him in very colorful detail what to do to her. This was a side of Lilith that I had never seen in all our years of marriage.

After Ray came it was Keith’s turn to fuck her, and finally Norman’s. All of them went at her like a bunch of horny sailors on shore leave, and each of them made her climax numerous times. When Norman got off her, Theo reached down and helped her to her feet. Then, without consulting either me or my wife, he proceeded to lead her upstairs to our bedroom. I noticed sperm dripping out of her snatch nearly every step of the way.

In the bedroom Theo took charge, instructing Lilith to get on all fours in the middle of the bed. She obeyed without hesitation. Indeed, she seemed almost eager to submit to being ordered about, totally controlled by her young lovers.

Theo now mounted her from behind and began riding her hard. At the same time, Ray got onto the bed in front of her, his erection aimed right at her face. Taking hold of her hair, he fed the entire length of his cock into her moaning mouth and started fucking her face, doing it so vigorously that his big balls slapped against her chin. I had always let Lilith set the pace when she sucked my cock, but now she not only easily accepted Ray’s hard thrusts, she also gurgled with delight as she pleasured him with her mouth.

It was now obvious that hidden inside my wife of 20 years had been a wanton cock-craving slut, and that realization turned me on like nothing ever had. I had always thought that Lilith was the most incredible woman I’d ever met, but now she was exceeding not only my knowledge of her as a sensual and loving wife, but my wildest dreams and fantasies as well.

Theo kept pounding away at her, he and Ray now getting a rhythm going, one of them thrusting in as the other pulled out, and vice versa. Then Theo added to the intensity by giving Lilith a swat on the ass. He did this several times, and by the third smack she was coming hard, her cries muffled by Ray’s cock embedded in her mouth. Theo continued to fuck her relentlessly through her orgasm, and when she had another almost immediately afterwards, he fucked her through that one as well.

By the time Theo finally came inside her, both her ass cheeks were red. As he fell away from her, Keith eagerly took his place, and when Ray shot down her throat, Norman was there to take over for him, fucking her face just as enthusiastically as his buddy had.

The four of them continued fucking the hell out of my wife for the next few hours, often double-teaming her as she continued to get off endlessly. They finally finished off with a circle jerk all over her gorgeous tits. Despite all the sperm they had deposited inside her, they still had enough to coat her chest with a healthy sheen of their youthful seed.

After that they left, thanking us both for the best time they had ever had, and volunteering to help out again any time we wanted.

When they were gone I gazed in awe at the sight of my exhausted, sperm-soaked wife. I was so turned on that I stood over her and jerked off, adding to the coat of sperm decorating her supine body.

When Lilith collected herself, she smiled at me and said that she could make a habit of this. I smiled back and told her that as long as I got to watch, I was all for it.
