Alyssa had heard the rumors, but Jack was her best friend, so she tried not to picture him like that. A man with an eight inch penis. They had been friends for years, and there had been no tension or strangeness between them. It was true, they were both young and beautiful. Jack with his muscular, lean body and curly, blond hair. Alyssa herself was a striking brunette, her hair the color of chocolate. Her skin smooth and unblemished. She was thin at the waist but she was curvy also and had broad, round shoulders and very perky, ample breasts. Her ass was muscular and round, and she liked to show it off when she walked, though not around Jack. 

One hot summer’s day, Alyssa and Jack had decided to go swimming together at a hole in the river, deep in the woods. After a short hike, they arrived at the swimming hole. Alyssa quickly removed her shirt and shorts, revealing her red bikini. Very nonchalantly then, Jack said, “turn around for a minute, I still need to change into my trunks.” 

Alyssa turned around, but only for a moment. Something came over her. Curiosity? A sudden excitement about those rumors she had always heard? After a second or two she turned her head, just a little, towards Jack. She could see him standing side-on to her. He was just stepping out of his underwear, while holding his trunks in his hand. 

From this side-on view, Alyssa could make out the full eight inches of his thick, flaccid cock, which hung majestically over a large set of balls. “So, the rumors are true!” she thought to herself. 

Alyssa began to feel wet between her thighs and, as she saw Jack stepping into his trunks, she fully turned around and said “No Jack, keep them off.” Jack was startled at first, but he was not embarrassed, for he knew what a pleasurable sight he was to a woman. 

Alyssa walked towards him then, removing her bikini top, and then her bottoms, tossing them to the ground. “Let’s swim naked together,” she said. 

Holding hands, they jumped from the rocky edge into the deep, dark pool of the river. The water was cool, but not cold. When they resurfaced, they swam in together and embraced under a canopy of tall, leafy trees that overhung the river. They kissed each other then, while treading water, the sunlight and dappled shadows flickering on the surface around them. 

The slow movement of water over their bodies was invigorating. The feeling of the cool water against Alyssa’s bare sex began to excite her further.  

Alyssa reached down then and felt Jack’s cock, which was still very long, despite the cool water. When she felt it’s warm, meaty thickness, she gasped. Her hand moved along its length, downward, until she reached his balls. She tried to fondle them and she noticed that she could not hold both of them together in one hand.

How had she spent all these years never seeing or touching this part of Jack? “What a waste,” she thought. Alyssa’s pussy burned then with longing. She pushed against Jack’s chest while treading water, forcing him to swim backwards to the rocky shore. All the while, Alyssa would not let go of his cock. Jack climbed and hopped out of the water and sat upon the large, flat boulder, just above the river’s surface. He sat on the very lip of the boulder and hung his enormous cock and balls down over the ledge. 

Alyssa swam under him and lifted her head towards the tip of his low-hanging cock. She was still floating in the dark pool, so she had to be very agile and controlled in her movements as she made each attempt to lick his balls and his thick, dangling member. 

Finally, she found some footing and was able to brace herself and stand a little out of the water. Her beautiful breasts emerged with her nipples as hard as pebbles. She could reach his cock now with both hands. She placed one hand around the base and then a second hand on the shaft. Still, there was room for a third hand. She kissed his foreskin and began to suck it into her mouth. As she pumped both of her hands along his length, she tried to take the head of his cock into her mouth as well, but he was too large. Jack was growing fully hard now. Frustrated, Alyssa demanded that Jack fuck her instead. 

Jack helped her climb out of the water onto the boulder. As he lifted her from the dark pool, he reached a hand in under her and held it against her cunt, with one of his fingers searching and then rubbing her clit. Her soft lips were plump and already well-lubricated. She was ready for him. 

Alyssa got on her hands and knees and waited for Jack to begin, biting her lip in anticipation. The sun on her back was warm, and the air felt fresh and alive with trees. At first, Jack could only fit the head of his cock inside her. Soon, though, he could push half of his fully-hard-length into her cunt. At only halfway in, he could already feel the tip of his cock hitting her cervix. 

As Jack’s cock made its first couple of thrusts inside Alyssa, she moaned deeply. Then Alyssa bent down, further forward, bracing herself with one forearm, freeing her other hand to reach back and play with Jack’s balls. 

Jack grabbed both of Alyssa’s ass cheeks and began to fuck her harder. As he fucked her, he noticed the way her plump, muscled ass bounced and this began to drive him mad. He fucked her desperately then. Frantically.

Alyssa moaned and began to whimper as her breasts and entire body bounced from Jack’s hard thrusts. She let go of Jack’s balls then and began to rub her clit. She was getting close. Jack too was approaching orgasm, as his thick cock was clenched so tightly by Alyssa’s pussy. 

They were both approaching climax when, suddenly, two couples appeared out of the trees, just several paces away from them. For a split second they both considered not stopping. But, half a second later, they thought better and jack pulled out his giant, glistening cock, and then both he and Alyssa stood and dove back into the water. 

The other couples hadn’t seemed to mind catching these two beautiful people fucking. They simply undressed and became fully nude themselves, joining Jack and Alyssa in the deep, dark pool. 

At the far side of the pool, Jack and Alyssa found a submerged boulder that they could stand on with only their heads rising above the water. They both wanted to finish what they had started. Alyssa reached under the water and found Jack’s cock still hard. With one hand she fondled his balls, while, with her other hand, she began to jerk him off, hard and fast. 

Jack squeezed Alyssa’s ass with one hand and fingering her clit with the other. They both had their eyes closed now, their heads leaned in together and touching in a heightened moment of pleasure before orgasm. And then, like a storm rising and thunder crashing, they both came. Jack’s cum exploded into the river water, and Alyssa’s legs faltered and trembled so that Jack had to hold her up by her cunt. 

When they finally came to, and took in the world around them, they noticed that both of the other couples were over by the rock that they had been fucking on. The two boys were seated on the edge of the rock, and the two girls were busy sucking their cocks. 

Surprised by the sight, but also a little relieved and excited, Alyssa and Jack swam over to join them, to see what kind of fun they could get up to next.
