It was certainly turning out to be an interesting summer. Beth, Jason's sixteen-year-old niece, was staying with him for two months while her parents were away on business. Much to his amazement, somehow, they ended up being lovers. After three weeks of hanging out together and having mind-blowing sex, they settled into somewhat of a routine. They would get up, hang by the pool or go into town for the morning, and come home. Jason would work on his next project during the afternoon, then after a late dinner, they would go to bed and explore each other in amazing ways. Beth had a perfect body, but what made the difference, was that she was incredibly sexy. She knew how to carry herself, dress, act and talk in the most seductive manner. Even though Jason was twenty-eight to her sixteen, she was hands down the more desirable girl he had ever known.

At one point though, she must have been getting bored.  While looking for something interesting to do, she found a photography class she was interested in attending. After doing some research, they signed her up. The class was at a local community college and lasted a week. Classes were from 9:00am to 4:00pm. Computers were provided, but she needed to bring a camera. Fortunately, Jason had one that was perfect for the job. The next Monday, he drove her to the college. They had a tender kiss before she got out of the car.

As the day went on, Jason found himself missing his niece. He kept wondering what she was doing and wishing she was back. He knew this was silly. After all, she was going to be leaving at the end of summer.

Later in the morning, Beth texted, "Hi, Uncle Jason. I'm having so much fun, and I made a new friend. Her name is Jamie, and we are work partners for the week!"

She texted him a picture of Jamie that was obviously taken in the classroom. She was just as beautiful as Beth, and perhaps a year or two older. Jason didn't remember girls like this when he was in college. 

Shortly after lunch, Beth called. "Hi, Uncle Jason! Guess what? Jamie is going to give me a ride home. She lives just a couple miles away. Is it okay if she comes for a swim?"

"Sure Beth. She's more than welcome. It will be fun."

Beth and Jamie came in the door later in the day. Beth went up to her uncle and hugged him tightly.

"I missed you, Uncle Jason."

She gave Jason a soft, lingering, kiss on the lips. It was definitely not the typical kiss a niece would give to her uncle. Jason's hand automatically slipped down to Beth's ass and fondled it. When he realized he shouldn't be doing that in front of Jamie, he quickly moved his hand up, but Jamie had already noticed. Jason glanced over at her and briefly saw her look of surprise before she recovered. Beth let go of her uncle and made the introductions. Jason Shook Jamie's hand and welcomed her. She was even more attractive in person.

When Jamie and Beth were alone, Jamie asked, "Are you sure Jason is your Uncle? I saw the way you kissed him and the way he grabbed your ass."

"Yeah, he really is my Uncle, but we're pretty close."

Jamie winked, "I bet you are close. He's so hot, and you're gorgeous. I sure don't blame you two for messing around."

"It kind of happened, but I'm so glad it did. I can't explain what it is, but the sex we have is something I never even dreamed of."

-----

The girls got along like long lost sisters. Over the next week, Jamie spent a lot of time at the house. Jason didn't mind at all. He found that he had a strong attraction to Jamie, and it seemed that Jamie felt the same way. Jamie liked to flirt a lot too. She would touch Jason while they were talking and brush against him when she had the opportunity. Jason often got hard around the girls, and he wasn't always successful at hiding it. It didn't help that the girls were often wearing next to nothing. They were either in swimsuits by the pool or prancing around in T-shirts and panties.

When Jamie would go home, Jason put his pent-up arousal to good use. He and Beth would usually have fantastic sex as soon as Jamie was out the door. They would fuck anywhere, on anything.

Over time, Beth noticed the growing attraction between Jamie and her uncle. At first, she was happy that Jamie and her uncle got along so well. At times though, she got a little jealous. It was a strange feeling for her. She wasn't sure which one she was more jealous of. When it seemed like she was being left out, she would insert herself into the situation, like give her uncle a hug, or sit on his lap. She enjoyed being able to arouse him and feel his hard cock against her.

When the girls were alone, Jamie said, "Beth, don't be jealous of me and Jason. I know you two have a special relationship. I guess I'm the jealous one here. I have never had anyone that loved me the way your uncle loves you. You can tell he truly cares about you."

"Jamie, I'm sorry. It's just that I have had uncle Jason all to myself up until now. When I see you two getting along so well, I sometimes feel left out."

Jamie opened her arms to Beth, and they hugged tightly for a while. At that point, Jason walked in.

"Hey, girls, is something wrong?"

They broke their embrace and were both misty-eyed.

Jamie was the one to speak. "Everything is cool, Jason. We were just having a girl moment."

Beth had an idea. "Uncle Jason, Jamie's parents just left for a couple of weeks. Do you think Jamie could stay here with us?"

While looking at Jamie, he said, "I think that's a great idea! What do you think, Jamie? Do you want to join our family for a while?"

Jamie was so excited about the idea. "Absolutely! I'll take Beth with me to my place, to help me grab my stuff."

The girls were gone about an hour. During that time, Jason worked out in his gym for a bit, had a shower, and changed into his swimsuit. By the time Beth and Jamie returned, Jason was already out at the pool enjoying the sun along with a bottle of beer.

Beth called out to him, "We're going to change Uncle Jason. We'll be out in a little bit."

They went to Beth's room. They decided that she and Jamie would share the room. It would be fun!

The girls started to undress to change into their bikinis. Beth couldn't help but notice Jamie's bare pussy.

"You shave down there? What's that feel like?"

Jamie responded, "It feels wonderful. You should try it. I bet your uncle would love it. Do you want me to shave you?"

"Okay! Let's do it. Uncle Jason will be so surprised!"

Jamie put a towel down on the bed and had Beth lay down. She got her trimmer from her bag and got down close to Beth's pussy. Jamie felt a twinge of excitement about being so close to Beth in this way. She carefully started to trim the pubes around Beth's pussy. She was careful to not press too hard. When she was done, she brushed the remaining loose hair away.

Next, she got some shaving cream and a new razor from her bag. As she walked back to the bed, she admired how sexy Beth looked, lying naked like that. Jamie squirted some cream in her hand and gently spread it around Beth. She looked up to see Beth watching her.

"Don't worry. I'll be real careful."

Jamie proceeded to shave around Beth's pussy. She used her fingers to pull the skin taught, to get as close as possible. Jamie noticed Beth squirming a little as she paid close attention to her pussy. She began to smell the musty excitement from Beth. Jamie pressed on her hooded nub as she finished up, and used the towel to wipe any remaining cream. That's when she heard Beth moan out loud."

Jamie circled her finger over Beth. 

"Jamie," Beth panted.

Jamie couldn't resist. She slid the tip of her tongue into Beth's slit, licking and sliding up to her clit. Beth moaned deeply. She lifted her hips to Jamie's mouth. Her fingers pinched her nipples, as she felt Jamie explore her. Jamie pulled back the hood, exposing Beth's little pink button. It was nicely swollen, allowing her to nudge it around with her tongue, as she slipped two fingers into Beth's wet pussy.

"Oh, God," Beth cried out, "Jamie..."

Beth felt her tummy tighten, as she spasmed into her climax. Her legs clamped on Jamie as she continued to shudder. Eventually, she relaxed, and her breathing began to slow.

Jamie gave one last kiss to Beth's pussy before moving up on the bed to join her.

Jamie spoke softly, "I'm so sorry, Beth, I don't know what came over me. Honestly, I didn't know that was going to happen. I've never done that before."

Beth turned her head. Jamie's lips were glistening wet. Beth leaned a bit towards Jamie, and their lips met in a soft kiss, followed by something much more passionate. Beth loved the taste of herself on Jamie's lips."

"I loved it, Jamie. It was a little bit of a shock at first. I've never really thought about another girl like that, but that was awesome."

There was a knock on the door.

"Hey, are you two coming out for a swim?"

Both girls giggled, and Beth answered, "We'll be out in a minute!"

They quickly changed and strolled out to the pool, hand in hand. They all spent the rest of the day enjoying one another's company. Jason couldn't help but think how beautiful these two girls were. They could easily be confused for sisters. Their eyes were their most distinguishing features. Jamie had sparkling green eyes, compared to Beth's beautiful blue eyes.

When it came time to call it a night, Jamie gave Jason a tight hug, followed by a soft lingering kiss. Jason immediately started getting hard. When it was Beth's turn to say goodnight, the only way to describe her kiss was hungry.

She whispered, "I'll be in for more in a little while."

Jason barely had time to dry off after his shower, when Beth came into his room and slipped out of her robe. After all the flirting throughout the day, he was more than ready to make love. They met at the edge of the bed and kissed each other with a mounting passion. Jason guided her down onto the bed and moved over her. They continued kissing as his hard cock pressed down against her. He was lost in his desire and didn't immediately register someone else climbing into the bed. He felt a hand on the back of his neck, pulling him. He realized it was Jamie. He didn't hesitate to kiss her deeply. The first time their tongues touched, it felt like a spark of electricity. Jason was more aroused than ever.

Then, Jamie turned to Beth, took her face in her hands, and kissed her with all the emotion she felt. Beth pushed Jamie onto her back and started sucking on her nipples. Jason was fascinated, seeing his niece like this. It was the most erotic thing he has ever seen. He watched as Beth kissed and licked her way down until she was between Jamie's legs. Her tongue danced over her clit, causing Jamie to moan with pleasure.

Jamie beckoned Jason closer. She took his cock in her hand and began to stroke it. She guided him closer and took him in her mouth. With one hand holding his balls, her tongue swirled around the head, before devouring it all. She had a hard time concentrating on Jason. Beth was working feverishly on her pussy.

Jamie released Jason's cock from her mouth, looked up at Jason, and with her eyes, she motioned to Beth. "Go fuck her," she whispered. 

Beth had never tasted another girl before, but she loved the taste of Jamie. She was so turned on, she herself was dripping wet. That's when she noticed her uncle had moved behind her. With his hands on her hips, he pressed his rock hard cock into her pussy. With each stroke into her, Beth's mouth pressed down on Jamie's clit. 

Beth was the first to climax. Her cries of pleasure were muffled by Jamie's pussy, but the vibrations they produced, sent shock waves through Jamie. She couldn't last any longer, and she, too, came hard. The pleasure that Beth gave her, along with seeing Beth being fucked by her uncle, sent her over the edge. Her hands gripped and pulled at the bed sheets as waves of pleasure rolled over her twisting body.

Finally, Jason exploded into Beth. Ropes of hot white cum spewed into her waiting pussy, coating her inner walls.

Jason eventually collapsed onto the bed. He was totally spent. Beth curled up to his side, snuggling up close. Jamie took Jason's softening cock in her hands, and gently licked and sucked him clean. She loved the taste of Beth and Jason's love mixed together. When she finished, she curled up on the other side of Jason. With their arms and legs intermingled, they fell asleep with exhaustion.
