I’ve been reading Penthouse for 20 years now, and have finally experienced a sexual adventure of my own that I think merits inclusion in your “Forum” column.

One late summer day, my wife Donna and I were in the midst of throwing our annual outdoor party at a cabin by the lake when Ray and his wife Jackie arrived. Jackie was a frolicking vision, wearing a straw hat and daring knit skirt that showcased her fine legs and curvaceous ass. Her husband was my wife’s childhood friend, so after the introductions, he and Donna ventured out toward the mountains to catch up on a decade of lost time. Between rounds of horseshoe pitching, I got to know Jackie and took further note of her luscious form.

When Donna and Ray returned, they went into a huddle with Jackie. A little later Donna informed me that Jackie was bisexual — just like Donna herself — and that Ray and Jackie were into swinging and wanted to get together with us that evening. Since Donna and I have been dabbling in swinging for a few years now, I gave my enthusiastic blessing to a get-together. Meanwhile, I tried to contain my excitement.

At sunset, when all our guests had left, I proposed a bit of skinny-dipping in the lake to revive our little party. Dusk masked all our inhibitions. The words had barely left my lips when bottoms and tops began sailing through the air. Soon we had paired off, embracing to ward off the chill, two couples linked by growing desire. As Ray and I held our wives from behind, Donna and Jackie reached out to each other, teasing, pinching, touching. I guided Donna’s hand to Jackie’s breast, eliciting a squeal of approval from our new friend. The two women leaned in and joined their lips in a deep, long kiss.

To my surprise, I grew hard in the chilly water. My wife reached down and guided my prick to her pussy lips. With one quick thrust, I was encased in her warmth. In the other half of our linked foursome, Ray entered Jackie. Our two-couple dance continued, with the girls grasping each other’s thighs for support. Donna also gave some of her attention to Ray, reaching between his legs to stroke his balls as he fucked Jackie.

The warmth of Donna’s pussy spread from my cock throughout my body, and while the others were beginning to shiver, I felt I could have remained in the water for hours. But surrendering to the majority, I retreated from the water and got dressed in preparation for a late-night campfire. As I closed the door of the cabin, I looked back to see my wife locked in a passionate kiss with Ray, while Jackie, reaching from behind, squeezed Donna’s tits and nuzzled the nape of her neck.

I was about to light the fire when Jackie made her way outside to where I was standing. After what had just gone on in the water, I moved my hand beneath Jackie’s tight cheeks. My cock, unfettered by underwear, strained against my jeans. As Jackie snuggled against me, I traced a finger down the crack of her fine ass and began kneading her buttocks. I longed to bend her over the picnic table, lift her skirt, and fuck her beside the fire under the rising August moon. I could picture the scene vividly, with Jackie rocking to my rhythm, her head craning back at the thrust of my cock, begging for more. The night was young, though. My self-restraint kicked in and we parted without a word.

Much later, when the fire had died down, Donna, Jackie, Ray, and I drifted to the back room of the cabin. With the preliminaries out of the way, we dove right into it. We’d teased enough. The four of us sat on the bed, the couples facing one another, me fondling Donna’s tits and Ray fondling Jackie’s. The girls kissed and gingerly ran their hands along each other’s body, outlining the curves of their breasts. As they became more involved, Ray and I backed away to enjoy the show.

Never a shy person, my wife took the lead. She reached across and pulled Jackie to her, playfully grabbing a handful of hair as she delivered a lusty kiss, first on the mouth, then on Jackie’s firm breasts and hardened nipples.

Encouraged from the sidelines by Ray, Jackie returned the favor, stripping Donna of her top. As Donna’s desire grew with Jackie’s licks and nibbles, she pushed Ray’s wife back down on the bed and deftly removed Jackie’s panties. In a flash, Donna buried her face in Jackie’s pussy, eagerly lapping at its juices.

I stroked my cock while Donna continued her delightful work. Across the bed, Ray fondled Jackie’s tits and moved his cock to her lips, filling her mouth as she moaned with pleasure from Donna’s ministrations. Soon it was Donna’s turn. As she lay back on the bed, Ray and I fondled her tits and ran our hands over her body, while Jackie, on all fours, hungrily ate my wife’s pussy.

I savored the view as Jackie ran her tongue over Donna’s exposed clit. Playing with Jackie’s firm round tits, I rubbed my stiffened cock along her ass and engorged pussy, teasing the sweet openings. Then, moving to the foot of the bed, I became better acquainted with that luscious ass. Burying my face between Jackie’s legs, I ran my tongue from her clit to her puckered bung hole.

A foursome offers both physical and visual delights, and I did not want to miss out on the show just across the sheets. My cock grew even harder as I watched Donna and Ray go at it in the other half of our torrid tango.

Donna and Ray were now making up for all those lost years. My wife’s lust-filled eyes spoke volumes as Ray moved his cock toward her mouth, and her hips softly rotated to the beat of Jackie’s tongue. Donna eagerly swallowed Ray’s cock and massaged his balls, eliciting soft groans from her old friend.

Jackie and I moved to the floor, where she now began to give me head. I looked up to see Donna going down on Ray with determination; he would clearly soon surrender to her incredible finesse. Jackie wielded an equally expert tongue, and I pulled her up as I felt my own orgasm coming near.

“Guests come first,” I said, creating a new house rule before diving between her legs. Meanwhile Donna, with Ray’s dong deep in her mouth, pressed her fingers into his ass and hungrily met each thrust. In less than a minute Ray threw his head back and groaned, filling Donna’s mouth with his hot white come. Donna leaned back in satisfaction, licking his jism from her lips.

Back at the foot of the bed, I resumed my happy task, with my tongue in the sweet folds of Jackie’s pussy, nibbling and licking away at her bud. As Jackie’s breathing became more rapid, Ray and Donna joined us on the floor to watch the action. “She’s going to have a big one,” Ray said. Sure enough, Jackie let out a series of cries as waves of orgasm overcame her.

The four of us took time out, savoring the moment’s erotic delight. Then Jackie looked at me and said she still had some business to complete. “Don’t worry about him,” my wife said with a laugh. “He’s had a couple of beers. It will take him hours to come.”

That was all Jackie needed to hear, and she went right back to work. Ray’s and Donna’s whispers grew ever more distant as Jackie’s lips and tongue masterfully caressed the head of my cock, which positively ached for release. I exploded inside her mouth, with a geyser that had been building for the past 12 hours.

At that point it was 3 a.m., and Jackie and Ray had to leave early the next morning. Donna and I let them get some rest and retreated to another room where I went down on my wife, giving her an orgasmic nightcap.

We basked in the glow of that evening for days, our desire fueled by our parting words that morning. “It was fun,” we all agreed. “Let’s do it again.” That was six weeks ago. Round two was last weekend, but that’s another story.
