Michael's eyes were wide open, brimming with excitement, pride, and unbridled lust. The room was filled with the symphony of bare skin slapping against skin and passionate moans, a sound that was both overwhelming and intoxicating. But what he was witnessing took him to a whole new level of arousal. There, spread-eagled on Tom's bed, was Jen - his wife of six years and lover of fourteen. On top of her, driving into her with deep, powerful thrusts, was Tom - their friend who had recently grown closer to them both.

Michael, with his extensive experience in watching porn, was impressed by Tom's stamina. The way he pounded into Jen matched the best porn actors he had seen over the years. But this was different. This was his wife, the only woman he had made love to in over a decade, being thoroughly fucked by their mutual friend. Tom's hips worked like a piston, plunging his thick, hard cock into Jen's dripping pussy.

Jen, on her second orgasm of the night, showed no signs of wanting to stop. The pleasure was unlike anything she had ever experienced. Michael was the second man she had been with sexually, after her last boyfriend. Sure, she had fooled around with others, but it never went further than handjobs. The only exception was with an Italian friend she had hosted years ago during the winter. He had flirted with her relentlessly and finally convinced her to let him into her bed. Even then, all she had given him was a blowjob before kicking him out. Now, here she was, her legs spread wide, another man's cock buried deep inside her.

Tom's cock was a stark contrast to Michael's average size. He was thicker, longer, and knew just how to use it. The moment Jen had given him control, Tom had taken charge, guiding her body to new heights of pleasure. It was a side of Jen Michael had never seen before.

It had only been an hour since they had sat on Tom's couch, drinking and discussing the boundaries for their night together. They had planned for days, making sure everyone was comfortable with the arrangements. Both Michael and Jen had the option to call it off at any point. But nothing could have prepared them for what happened next.

The moment Jen nodded her agreement to the final conditions, Tom gulped down the last of his drink, stood up, and hooked his finger in the front of Jen's tight jeans. Her surprised yet excited expression was all the approval he needed. With his finger still hooked in her jeans, Tom guided Jen towards his bedroom. Michael followed closely behind, his heart pounding with anticipation.

Tom's bedroom was a classic bachelor pad - clean but cluttered, with a bunk bed from his college days piled high with junk. The bottom bunk was made up neatly with clean sheets and pillows. Candles flickered on the desk beside the bed, illuminating the room with a soft glow. There were condoms and lube at the ready, as if the room itself expected what was about to happen.

Tom sat down on the edge of the bed, his legs spread wide. Jen stood in front of him, her eyes fixed on his. "Take your top and jeans off for me," Tom commanded, his voice firm but with a hint of a smile.

Jen glanced over at Michael for reassurance, realizing for a moment that she had forgotten he was there. Michael gave her an encouraging nod, a big grin on his face.

Her eyes locked with Tom's once more, Jen slowly lifted her top, inch by inch, revealing her beige padded bra that supported her supple breasts. She let the top fall to the floor and paused, allowing Tom to admire her chest. Then, she began to unbutton her jeans slowly, the sound of the zipper amplified in the silent room. As she brought the zipper down, the black fabric of her panties came into view. Jen shimmied the jeans off her legs, letting them fall to the floor. She stepped out of them, her underwear now fully exposed.

Michael's expression of lust turned to one of surprise as he took in the sight of Jen's thong. In all their years together, he had never seen her wear such revealing underwear outside of their bedroom. This was new, and it was clear that Jen had put a lot of thought into her choice of attire for the night.

The thong was a work of art, crafted to highlight Jen's luscious ass cheeks while leaving little to the imagination. A thin strip of lace fell perfectly between her exposed cheeks, as if it had been made just for her. It was sexy yet classy, a piece of clothing Michael had never dared to ask her to wear on one of their dates.

Tom grabbed Jen by the ass with both hands, lifting her off her feet. Her legs locked around his waist as his hands squeezed her firm cheeks. They kissed deeply, their tongues exploring each other's mouths. Tom's fingers hooked onto either side of Jen's thong waistband for a moment before she instinctively lifted her hips, signaling that she was ready.

Noticing Jen's eagerness, Tom grinned. With a swift motion, he pulled down her thong, exposing her naked body completely. Jen reached behind her back and unclasped her bra, letting the straps fall off her shoulders and hands. This time, she didn't look over to Michael for assurance. Tom climbed on top of her, their bodies pressing together as they kissed fiercely.

Jen reached for Tom's boxers but he grabbed her hands firmly, stopping her. He stood up and guided her to turn around. Tom's eyes drank in the sight of Jen's naked body, lingering on her toned ass. He stared at the birthmark on her left cheek - a mark that Michael had always found beautiful.

"Pull them down slowly," Tom ordered.

Jen reached for her thong and brought it down her legs as slowly as she could manage. As she stepped out of them, she realized just how soaked the fabric had become. Bending down with her legs straight, Jen clutched the black lacy underwear without picking them up. It was a vulnerable position, her most intimate areas exposed to Tom's hungry gaze.

Tom's eyes were locked on Jen's asshole and pussy lips, drinking in every detail. He had always admired Jen's ass and preferred women with toned butts and long legs. Now, he was getting a front-row view.

"Damn, Michael," Tom said, turning to his friend. "I'm so fucking jealous."

Jen picked up her thong hurriedly and placed it in Michael's hands. The two lovers locked eyes for the first time that night in Tom's bedroom. It was a look of genuine love, adoration, and pride in each other. They kissed passionately, holding onto Jen's wet thong together. It was a kiss that reassured Michael that Jen was always his, and at the same time assured Jen that he was always hers.

As they pulled away from the kiss, Jen turned back to Tom with a newfound confidence. "I'm ready," she said, her voice filled with anticipation for what was to come.
