AUTHOR'S NOTE: I'm the original author of this story and no one else. The author on another site named "Hearsz" and I decided to make two stories with the same idea, but with different celebrities, he used Lucy Pinder and it takes place during a Christmas party and mines is with Kate Upton and takes place at a family reunion. There's more differences than that and he even read this story before I uploaded it. So please do an proper investigation before falsely reporting stories.

There wasn't enough words to describe how excited Zachary was for the yearly family reunion. It was when most if not all of his family came together at their house and had a good time, but the main reason why he was always so excited about it was because it was almost an guarantee that his Aunt Kate would show up and he would get to see her. Every family reunion for the past 5 years, Aunt Kate would always show up even with her busy modeling career.
Now she was kind of Zachary's estranged Aunt as he had heard about her and talked to her on the phone from time to time, but didn't start seeing her show up to the family reunions until her modeling career blew up in 2011 and she's been coming to them every since. Kate would always bring Zachary a gift from her world travels, but with each yearly family reunion that passed by, Zachary cared less and less about whatever gift she brought him. Zachary Thompson was the guy that was invisible silent type who none of his peers seem to notice and as Zachary turned 18, he couldn't help, but be attracted to his sexy Aunt, in fact he would easily get turned on just at the sight of her.
Yes she was his Aunt and he knew it was wrong, but he couldn't seem to get his obsession with her in the bud. Some nights he would just lay in his bed and try to go to sleep, but he couldn't and just masturbate while thinking about his Aunt Kate. He would think about her beautiful smile, her gorgeous blue eyes, her curvaceous figure, and without a doubt her gargantuan sized breast. The things he would do to feel and squeeze them in his hands and to suck on them. Zachary didn't know his father as his mother was a single parent and as a result would shut some people out as he thought if the risk was them abandoning him then why bother making a relationship with them if it would be a waste of time, if they would just leave him as his father did. However, he did have one friend at school, a friend who had a heavy supply of dirty magazines.
It was the same friend that had gave him a copy of a "Sports Illustrated" magazine back in 2011 and to his surprise that he saw a very recognizable face... His Aunt Kate in the body paint section, this magazine that she held the title rookie of the year. There was multiple pictures of her in sexy poses in skimpy bikini's, that barely contained her ample breast and showing off her curvy body and that's what started his obsession over her. But his obsession really began last year when a bunch of pics of his Aunt Kate was released during what became known as "The Fappenning", where Zachary got to see his Aunt Kate fully nude and her ample breast and curvy body uncovered and even one picture that had cum on her back! And that's when his obsessive kind of lust for her really began. Seeing her fully naked in those leaked pictures drove him insane and made him even more infatuated with her, especially those huge breast of hers.
Absolutely every time the family got together, Zachary couldn't help, but look forward to what his Aunt Kate would be wearing, hoping she would be showing off more than enough of her amazing cleavage. More times than not, she did just that and when that happened, he would jerk off while thinking about fondling and sucking on her her massive tits like there was no tomorrow and would do so for weeks. He found ways to check out his Aunt, mostly at her incredible rack, without getting caught, and would even "accidentally" brush up against her nice round ass when he saw a few people passing by so he could use that as an excuse. Sometimes he would sneak in a glace, at her long, sexy crossed legs and or juicy round butt whenever she would bend over.
For this family reunion, Zachary helped out the best he could with helping his mother prepare the feast they had planned intently for the twenty distant family members that were coming to the reunion. From what his mother had told him, his Aunt Kate was bringing a guy with her this time, much to Zachary's dismay. He tried to look on whatever bright side there was to this, he couldn't find one, but thought to himself that he could be able to take a lot of mental pictures of her when she showed up, thus he would jerk off while thinking about them later that night after she had left and went on her way.
Around twelve o'clock, family members started to arrive and those that brought guest, they came with them. Everyone went outside to the back yard, where everything was set up, from the food, drinks, games, and so on. Everyone gave their greetings, hugs, kisses, and were catching up with the people they hadn't been able to see or talk to in a while, all of this was going on while Zachary was anxiously waiting for his Aunt Kate to arrive.
Better late than never, Zachary's mouth dropped open as Kate Upton walked out into the back yard where the family reunion had already began as people already began partying. Kate looking as sexy and desirable as she always had looked in all her photo shoots. The famous model was wearing a red blouse with a black skirt, the tight body clinging outfit accentuating her wide hips and luscious round butt. She was wearing black stockings over her long legs, which looked completely luscious, her high heels clicking across the porch as she walked up to him. Zachary couldn't help, but watch in awe as he checked her out and then went back up to his Aunt's delicious looking tits, her tight blouse barely concealing her massive tits.
She looked gorgeous when she smiled, flashing her pearly whites behind those soft soft dark red lips. In fact, gorgeous was an understatement, Zachary felt his cock twitch at just the sight of her. Him to see her like this, he was feeling a whole different sensation compared to when he jerked off to sexy pictures and nude pictures of her. When his Aunt was hugging and laughing with his mother, it hit him like lightening that Kate had came by herself, and not with the guy she was supposed to be bringing with her. His thoughts were confirmed when he heard his mother asking Kate where the guy was, if he was her new boyfriend and if he was coming later, but Kate quickly shut that down and said "I don't feel like talking about it."
It was obvious that she was very upset with him, but Zachary on the other hand couldn't have been more happier. As the sisters caught up, Kate's eyes locked upon her nephew, who found the courage and was making his way over to her as his mother walked back inside the house, going to the kitchen to get something.
"Hey there stud bucket. Wow you really have grown since last year! You just turned 18 a few weeks ago and you're already looking all manly!" Kate said with glee, she had always called him stud bucket.
"Hey Aunt Kate," Zachary replied, holding out his arms for a hug. Kate lovingly gave him the hug he wanted, and the teen savored every moment of having his Aunt's sexy curvy body pressed up against him, her large soft breasts pressing up against his chest. When he finally did find the strength to let go of her, he looked down giving him the prefect view of her deep cleavage, his Aunt not even aware that her twin globes were having such a big effect on him.
"Uh-huh let me tell you a little secret..." Kate leaned in her lips close to his ear, "My eyes are up here sweetheart," she said laughing, as she looked up to me pointing upward from her heavy breast. Zachary was in a short panic as he was busted, but gladly his Aunt wasn't offended by him not being able to take his eyes off her milky jugs at that moment.
As the next few hours past, Zachary was like a personally servant to his Aunt, more than happily helping her and his mom out whenever he could, he did this as always to make sure everyone was having a good time. But to be honest, it was also so he could spend as much time as he could with his Aunt Kate as he wasn't sure when he would see her again after today's reunion. Although he had a secret picture collection on his laptop of his Aunt which was more than a few thousand, some being topless as he saved the pictures of her from "The Fappenning", he still was in awe of how astronomical the size of Kate's breast were, especially when her deep cleavage jiggled, bounced, and swayed when she walked and leaned down to pick something up that had fallen.
As the time the family reunion was coming to an end, Zachary began to feel down as he knew it was just a matter of time before his sexy Aunt would say her goodbyes and leave until the next year. He hugged her tight with all he had as she kissed him on the check, the teen trying his hardest to hide the true fact to why he was so disappointed. He watched as his Aunt gathered her things and headed for the front door, her curvy round ass swaying from side to side, the door closing behind her. A few times Zachary thought that if was unfair to have an Aunt as sexy as Kate Upton, because he knew it was wrong to have these kind of thoughts about another family member. He ended up feeling bad when he had a sexual thoughts about her.
Zachary knew that there was nothing else left to do, but go to his bedroom and fantasize about the last few hours with his Aunt while jerking off. When he got to his bedroom, he closed the door, took off his pants and underwear, and hurried into his bed pulling the covers over his waist, more than ready to jerk off.
Unbeknownst to Zachary, his mother had caught up with his Aunt in the garage, the model about to get into her car.
"Hey sis, before you leave can you do me a favor?" Kate's sister asked.
"Um sure. What is it?" Kate asked curiously.
"Mom's car broke down so I'm taking her home. Normally I'd ask Zachary to come with us, but I know he gets car sick and with mom living on the other side of town, I know that would come into affect. Would you be able to stay behind and watch him while I'm gone?" Zachary's mom asked.
Kate nodded her head.
"Um... I guess I could do it. How long do you think you'll be?"
"It depends on traffic, but it's usually an hour, hour and a half. Is that ok?"
"Yeah, I already don't get to spend enough time with my nephew as it is. So I wouldn't pass down the opportunity right now." Kate said with a little smile.
"Ok great. Can you go get the rest of mom's things while I'll help her to the car? I'll take her now so I won't be holding you up in case you gotta be somewhere."
Once Zachary's mother had gotten her mother into the car while Kate got their mother's other belongings packed into the car, they took off after Kate had waved goodbye and gave their mother a kiss. She headed back inside the house, removing her trench coat. She began to notice that it was quiet and her nephew was nowhere in sight, so she decided to go up to his bedroom to see if he was there.
Meanwhile, the heavily breathing teen was effortlessly stroking his hard cock, jerking his throbbing cock to pictures of his sexy naked Aunt that were on display on his laptop from her leaked pictures from "The Fappenning" and from her sexy pictures from the "Sports Illustrated" magazine. Zachary saw the images for a short while when he closed his eyes, seeing how sexy his Aunt looked at the family reunion earlier that night. He imagined her leading him to his bedroom by the hand, she making sure he sits down at the end of his bed, and slowly taking off her clothes as she teases him and continues to take off her clothes in front of him showing off her naked voluptuous body. There was no need for him to imagine what her humungous breasts looked like nude, because he had her nude pictures right on his laptop.
"Oh damn Aunt Kate... I want to fuck your big titties and cum all over them!" The teen moaned as he gripped his cock harder and worked faster. But before he had a chance to bring himself to cum, he was interrupted by a soft knock at his bedroom door. The teen stopped like if someone put pause on a movie or TV show, hearing a familiar voice from the hallway, outside his bedroom.
