My great step-niece Jill always liked to visit from Idaho for the summer, and I said it was fine for her to bring her best friend Shawn, as we had plenty of room. Wifey was leaving for a couple of weeks to visit her best friend in the city, something she did every year since retiring from the business world, and something that always included a shopping odyssey or two, leaving me with the bills. Ah, the joys of middle-class success and thirty years of marriage!

“Sorry,” she said, not too convincingly, as we changed bedding in the guest room, “this is the only time Bella has off before she and Ron leave for their summer cruise of the islands.”

I wanted to believe her.

"You can handle them, champ." Her eyebrows rose, and she gave me that look with her hazel eyes.

“Easy peasy,” I shrugged. “Whatever.” Drawing from past summers, my thought was I’d be dealing with a couple of giggling teenagers. “Watching them will be a breeze, wife of mine,” I said with a tinge of sarcasm in my voice. “You know what they do, mostly stay up late, mesmerized by their cell phones when they’re not watching movies, living on pizza or popcorn, or talking about boys. You know…just being ordinary young women.”

“You sound like you know what you’re doing, then,” Wifey smirked. What a smartass.

"I’ll just chill in front of the TV and watch football," I returned the smirk, self-assured with my best-laid plans.

“And swill beer, no doubt.” She shot me a look, eyebrow arched. “You know it won’t be totally hands-off. Bored teenagers get up to the worst mischief!”

“Okay, then,” I scowled, changing a cotton pillowcase. “We’ll go to the zoo, maybe the waterslide, or the mall. For Christ’s sake, they’re adults! Jill will be in college next year!”

“Good choices…and there’s something else, something very important.” God, she was on a roll. “You know how you get after a few beers.” She was referring to the magic power of alcohol to enflame my libido, turning me into a walking hard-on. Anyone, or anything, was game. “You keep it clean while those two are here.”

“What the fuck?” I dropped the pillowcase. Now I was pissed! “Just hold it right there. When have I ever acted inappropriately around Jill? What the hell are you talking about?”

She wasn’t buying it.

“You know,” she pulled the blue fitted sheet taut on the guest bed nearest the window, “last year by the pool while our sixteen-year-old great step-niece frolicked in the water, day after day? You were right there, pretending to read a newspaper. Ha! Then she stretched out to get some sun with practically nothing on. I thought you were going to come unglued. Even with those dark sunglasses, I can tell where your eyes are looking, not to mention that bulge in your swim trunks. You don’t know how close I came to smacking you!”

“Nonsense, all of it!” I tried to sound sincere, but it was a farce. Still, I couldn’t concede defeat. “Jesus, honey, she’s family!” Well, family, as far as we were concerned. She was the youngest daughter of my dearly departed step-sister, Ruth, so there was no actual blood between us, but no matter, our conversation had gone off the rails! My wife was no prude by any means, but after decades of marriage, she knew me inside and out.

“Okay, then,” She said, smoothing out the top cover.

Wifey didn’t see the point of pursuing the matter further, but she was right. How little I knew, and how my perceptions would soon be upended as the day came.

And it did come.

My world certainly changed upon Jill’s arrival that sweltering day in early June. She took me by surprise as she walked through the door. Last time I saw her, she was already a beautiful young woman, but now a year had passed, and she was a senior in high school, about to graduate with honors. She had come into her own, and, from what I heard, the same was true for her friend, Shawn.

“Hello, honey.” I hugged her, but not too tightly, trying to keep a sliver of daylight between our bodies. She was having none of it, pressing her body against mine, clinging for several seconds, while I felt blood rush to my cheeks and my cock.

After the initial jolt, I began to assess the situation. I managed to push guilty thoughts aside and enjoyed their presence, both as an uncle and a man. The sound of easy laughter and their effervescent energy brightened the house, and it was fun to watch these gorgeous young women bouncing around in their short shorts and little tank tops.

Football be damned, although I had money on the game that weekend. I pretended to watch television, but in reality, I was eyeing both of them curled up on the big sofa as they alternated between looking at the game and their phones, knees drawn up. I gazed with longing at the strips of silky fabric covering their sweet pussies.

Never had I been so grateful to have a modest swimming pool in the back yard as now. I had it installed years ago for our own kids, who were now grown and out of the house. After the game, they suddenly appeared in skimpy bikinis.

Goddamn! I thought, trying to keep my eyes from bugging out. Do they know what luscious pieces of ass they are?

“I’ve been thinking about the pool for months!” Jill squealed, Shawn following closely behind. I couldn’t help but notice Jill’s erect nipples pressing against the sheer white fabric of her top. Her breasts weren’t very large, but still lovely, firm handfuls. Shawn, with her thicker physique, was more well-endowed, her breasts jiggling. To my delight, I could see her large, dark areolas peeking through the fabric.

“It’s been waiting for you,” I smiled. “Enjoy!”

Of course, I had to crack open a beer and join them, if only from a distance. I relaxed on a reclining lawn chair in the patio, sipping cold suds, marveling at the wonderment before me. Watching them splash and frolic in the sparkling blue water became torture, and my erection throbbed urgently. No longer did I see Jill as just my great step-niece; I now saw her and Shawn as young women in their prime, ready for love.

Surreptitiously, I rubbed my fingers up and down the bulge in my shorts, watching their wet, barely-concealed bodies. God, I was such a horny dog! This was my own almost-relation! Still, what was the harm?

Hidden by the shade, I slipped my fingers under the elastic waistband of my red-and-blue striped swim trunks, gripping my cock. I was fortunate to be decently endowed. A little over eight thick inches rarely failed to satisfy, and was definitely a handful. Firm strokes, slow and steady, pulling all the way back until the skin was taut, and I was soon on my way. I never broke my laser focus on the two, Jill with her pale, freckled skin and Shawn with her medium-brown tone, a hint of a birthmark peeking out from the side of her bikini bottom. They never had a clue I was about to climax, and that they were the reason.

That’s it…that’s it…make it cum, sweet ladies. Rock your world and leave you full of my seed! Ohhh…god…daaammmnnn!!!

Fighting to keep still, I clenched my teeth, body tensing, as I released a thick load, all the while never breaking my gaze from the objects of my affection. Jesus, the orgasm went on and on, and I worried about cum dribbling out of my trunks or making a big, embarrassing stain. Finally, when everything stilled, I took a deep breath and quickly gulped down my beer before going inside to change out of my cum-soaked garment.

That evening after dinner, we ended up in the living room again, watching TV. The atmosphere was low-key as all of us gazed at the boob tube silently. I dozed a bit until I heard giggling, which stopped, then started up again. Opening my eyes, I figured the two had found some funny videos on their phones. Looking over to them on the sofa, I saw they were looking back at me! Before I had the chance to react, I realized I was sporting a full-on boner!

“Having a good dream, Uncle Bob?” Jill managed to blurt out before giggling again. Shawn pressed her face against Jill’s naked shoulder as she tried to contain her laughter. I had no recourse but to leer at them, adjusting my shorts, still failing to hide my erection. What I really wanted to do was let it free and invite them over for a ride. Of course, I masturbated again, later that night in the privacy of the master bedroom, this time to a fantasy of them watching.

The next afternoon, they were back in the pool. Once again, I hid in the shadows, sipping brew and playing with myself, slowly working to completion. Jill was a devil and managed to pull Shawn’s top off. Time froze for a few seconds as the full-bodied young woman shrieked with surprise, her ample breasts in full view, wet and bare, large areolas surrounding hard, thick nipples. The next moment, she dove beneath the water’s surface, only to come back up fully covered.

“Oh, Jill, I could strangle you!” Shawn laughed, glancing in my direction.

“Uncle Bob,” Jill called out, “Why don’t you join us? All you do is lie there and sip that shitty beer.”

“How do you know it’s shitty?” I asked. Jill giggled.

“I’ll never tell.” They bobbed up and down, arms around each other, looking like sin incarnate. “I don’t understand why you spend a lot of money on a swimming pool and never use it yourself!”

“Come on, Mr. Perry!” Shawn called out.

Jill mumbled something I couldn’t fully hear, but it sounded like “Come play with us.”

My fucking boner wouldn’t go away. I hesitated, taking another gulp of suds.

“We’ll behave,” My great step-niece teased.

Somewhat buzzed, I mumbled to myself, “What the fuck” and rose to my feet. The next moment, I slipped into the water, a gorgeous water nymph on either side, as I looked up to the blazing sun.

“See, Uncle Bob?” Jill whispered, her mouth only inches from my left ear. I could feel her breath on my neck. “See how nice it is?” Shawn closed the space to my right, also coming within inches.

I nodded, feeling the nearness of two warm, supple bodies bobbing on either side of me. I fought hard to remember where my hands were, but before I could tuck them in, Shawn lunged at Jill, retaliating for her friend’s previous prank. Now it was Jill who was topless, her pert breasts almost touching my shoulder! What the fuck? I thought as I froze. Any movement and I would be in contact with sweet, teen flesh.

“Goddammit, Shawn!” Jill wrapped her arms around me, clinging to my body to hide her naked breasts. Of course, they pressed against me.

Oh, Jesus fucking Christ!

“Payback’s a bitch, girlfriend!” Shawn waved the little bikini top over her head.

They proceeded to wrestle, and who managed to be in the middle? ME!!! Oh, those perfect bodies rubbing against me, breasts from both sides pressing against my arms and shoulders, and their hands grasping at anything they could reach. Water churning all around me, I closed my eyes and concentrated on not taking them in my arms and ravishing them.

“Ha!” Jill shrieked, grabbing back her top.

Goddamn, she took her sweet time putting it back on! I tried to keep my eyes straight forward, but I couldn’t help but steal a glimpse of her delicate, pink areolas and small nipples, and dammit if Shawn wasn't still clinging to me. By now, my cock was hurting, and I felt like I was going to throw up.

“Uncle Bob?” Jill asked demurely. “Are…are you okay?”

Composing myself, I nodded.

Cum dribbled down the back of my hand for the third time that night. I was being tested by some higher power. I wasn’t necessarily a person of faith, but someone, or something, was testing me. “Fucking sweet cunts,” I hissed as the final load came out, but it wasn’t much. I milked my cock until there was nothing left. “Good pussies…goddamn good, good pussies.” I wondered if Wifey’s sixth sense was tingling just about then. My wife, Linda, was another story.

We met at, if you can believe it, a swinger’s party. I was coming off my first, thankfully short, marriage and was looking for fresh pussy. She was in the same situation, her abusive, soon-to-be-ex-husband now legally required to keep his distance. Strangely enough, we didn’t consummate our relationship until a few months later. In addition to the usual swingers’ gatherings, I took home several women, and she did the same with both men and a few women.

Her sexual openness intrigued me. We would talk about our partners and their particular, or peculiar, little peccadillos. I knew she was exceptional, different, so I hesitated, for the first time in my life, to make the next move. The night she invited me to her apartment is one I’ll never forget.

Of course, it became more than a one-night stand. We stopped swinging and became a monogamous couple, getting married in time, making everything legal and respectable. She became pregnant with our first, Adam, soon after. One child, then two, and before we knew it, four years had passed.

“Do you miss the life?” I asked as we cuddled in the darkness of the master bedroom after another round of lovemaking. She didn’t answer immediately.

“Do you?” She asked.

“I’m asking YOU, wife of mine!”

She smirked, playfully slapping my face. “Horny bastard.”

Raising two young children and both of us holding down full-time jobs didn’t accommodate swinging very well, but we managed. With a trusted, dedicated babysitter and the guise of extensive business travel, we scratched that itch. I preferred women, and with them had few requirements. Linda laughed when I said personality and personal hygiene were my standards, unless the potential partner looked like Zorba the Greek or Danny DeVito. Uh, no.

She, on the other hand, liked both genders and young ones, at that. Of course, they had to provide legal identification so we wouldn’t end up behind bars! Watching her go after some college-aged young man or woman and taking her supreme pleasures really got me going. When the third party was male, I allowed myself some leeway with gender preference. To this day, Linda and I share a private joke about how many cocks I had in my mouth during those years. Again, our outings dwindled to almost nothing as the kids grew up, but once Jeff, the youngest one, went off to college, we were back to our old ways.

Bella, the friend Linda was visiting in the city, was one of our swinging partners. It was right before our second hiatus. We, by then, were in our late thirties, and Bella was a dark, sultry Italian young woman of eighteen, a true Neapolitan goddess with a thick, luscious body, full bush, and insatiable appetite. Much to my delight, they took to each other exclusively until Bella married Ron five years later.

I knew that, depending on the proximity of Bella’s husband, she and Linda would be going at it like mad right about now. At times, I wondered if Ron was part of their arrangement. He struck me as too strait-laced, but who knows? I didn’t mind. Linda would come home after these trips with renewed vigor, and I would reap the benefits. That’s what I meant when I said my wife was no prude. Still, she was drawing the line at me dallying with my great step-niece and her nubile friend.

Back in the master bedroom, having wiped the cum away, I drifted somewhat, in and out of sleep, my mind filled with frolicking maidens. I was the satyr to their scantily clad nymphs. That was when I heard noises from the other room. The master bedroom and guest room shared a wall, so, filled with curiosity, I slipped out of bed and, crossing to the opposite side of the room, pressed my ear against the wall.

At first, the sounds were muffled, lacking definition. Suddenly, I heard a moan, then another. Resting on my heels, I sat on the thick shag carpet, again pressing my ear to the spot where I knew the guest room bed was located. The noises became voices. Then I heard Shawn.

“Why do you have these stupid panties on? Take them off!”

“Jesus, don’t tear them!” Jill replied, her voice somewhat higher-pitched than usual. “Let me do it.”

“Hurry up.” Shawn’s husky voice was the lower of the two.

“Okay, okay. Damn, when you want something, you want it now!”

Blood rushed to my neck and cheeks. What the fuck was going on? Shit, I knew what the fuck was going on, and dammit if my abused cock wasn’t starting to swell again!

“There, isn’t that better?”

“Uh, huh-h-h,” Jill breathed her words before gasping. My mind went wild, trying to envision what was transpiring only a couple of feet away. “But what if Uncle Bob catches us?”

“So what if he does, girlfriend? Please,” Shawn huffed, “your uncle would probably dive in.” Jill giggled.

“We have him so worked up, he’d cum before laying a hand on us.”

Now it was Shawn giggling. “Wouldn’t he?” Both fell silent, followed by more sounds of physical seduction. Jill spoke.

“Fuck me nice, like last time.”

I swallowed, feeling my heart beating in my throat. Goddamn, if they weren’t getting it on! After that, I heard nothing but heavy breathing, moans, and gentle creaking from the bedframe. In this situation, I thought Jill would be the aggressor, but like the song says, nobody knows what goes on behind closed doors. Perhaps Shawn was the butch and Jill the femme?

Oh, to be in the room with them, so frustrating, but with my presence, they’d most likely scream in terror, and that would be it. Or would they? They talked a good game regarding my participation, but words and action, as...
