I had been back home for about a week when my brother Daniel called me. It felt good to hear his voice. I had been in abroad for almost two years because the company had sent me there - I work at a rather successful tech company that I can't name in this salacious story, I hope you'll understand, dear reader. I had really liked my stay, but I had really missed my brother and my sister-in-law Lynn. It's hard to stay in touch, even if you really want to. Finding the right time for a long phone call can be a bit tricky because of the time difference, especially for people like me and Dan, people with a rather tight schedule.

"Dan! So good to hear from you! I would have called you anyway, today or tomorrow."

"Hey, Steve! How does it feel to be back home?" he said with his characteristic laugh. Daniel was three years older than me, and we had always been close, and in many ways very alike - confident and maybe a little ambitious. Perfectionists, you might say. We talked for almost half an hour, exchanged some funny stories, asked about work and friends, all that. When I asked about Lynn and their daughter Laura, Dan let out a slight sigh.

"Is everything allright?" I asked.

"Of course, Lynn is doing great, and Laura is fine, too, don't worry" Dan explained. "It's just one thing that I almost forgot to ask you."

"I'm all ears" I said, now a little curious. It wasn't really like Dan to beat around the bush.

"Do you remember that hotel I used to go to with Lynn and Laura? The one with the incredible sports equipment and gym?"

"Sure, you told me about it at least a thousand times" I said, unable to suppress a little grin that Dan most certainly could hear in my voice. Like myself, Dan and his whole family we're very much into anything gym, since childhood really.

"Well, I promised Laura to take her there from July 10th to 15th, everything's already booked."

"So?" I asked. "That sounds great, actually."

"Weeeell, the thing is, I fucked up my leg."

"What? And you tell me that now?" I loudly exclaimed.

"Don't worry, don't worry, it's no big deal at all, but the doc said I should take it easy for a couple of weeks. Pulled tendon, I had a little bike accident and fell on my foot. I mean, I could still take Laura there, but I wouldn't really be able to get anything much out of all the great equipment and sports courses, that would be pretty lame, so I wanted to ask you if you wanted to take my place? Everything's already paid for, you just have to take your car."

"Ummm..." I made, checking my appointment calendar that I always keep within reach. "I guess I could make it."

"That would be great, Steve! And you haven't seen Laura for what, two years?"

"Not in person" I said, "Only in a couple of video calls. I'd love to see her again!"

"So is that a deal?"

"You bet it is!"

When I parked the car on July 10th, a bright, sunny summer day, Dan and Lynn were already waiting for me in front of their house. We exchanged hugs and talked for a couple of minutes, but then I had to start checking my watch. Not that I was uncomfortable, but was a long drive ahead of us. When Laura finally emerged from the house with two big cases and greeted me with a tight hug and a kiss on my cheek, I almost couldn't believe my eyes. The girl looked stunning. Tall, lean and athletic, with gorgeously big blue eyes and long golden locks, there was something almost angelic about her. Had she always been so beautiful? She was now 19, almost 20, I reminded myself.

"Hey uncle Stephen!" she said with a bright smile, "I'm sorry for being so late, but packing the suitcases took a little longer than I thought." That made Dan laugh a little, and finally got a little grin out of me.

"Don't worry about it" I said, "Just let me get your stuff in my car and then let's go."

It was almost four hours of driving, five if you count breaks and lunch, but I thoroughly enjoyed it. I got along great with Laura. Not that I was surprised, necessarily, but not having kids of my own, I hadn't been sure if I'd really be in tune with what a girl of her age would be interested in.

"I hope you're not too sad your dad can't take you on this trip" I said at some point.

"Oh no, thank you so much for taking me, uncle Steve" she said, "I'm so happy to go with you, after not seeing you for so long!"

Well, if it was good enough for her, it sure was good enough for me.

When we finally reached the hotel, we hurried to go to our rooms. We both had our own beds, but shared a sort of living room with an expensive looking couch and both a dining table and a coffee table as well as an absurdly big TV. We spent most of the afternoon on the tennis court, and I have to say, Laura was an excellent player - and she was a sight to see in her tight white shorts, tight white t-shirts and her bright blue headband.

"That's it" I said, wiping the sweat from my forehead, "I guess it's time to get ready for dinner".

"Who won? Did you keep track?" I said with a big cheeky grin that indicated that she knew the answer already.

"You know damn well" I said, laughing heartily and pretending to try to hit her ass with my tennis racket. "But it's only because I'm tired from all the driving. I'll ruin you tomorrow!"

"We'll see!" she said, taking a cute, cheeky pose that really flattered her ass... her gorgeous, firm ass. It wasn't just the tennis that had made me sweat, I'm pretty sure.

When I went to the shower after her, I checked my watch before placing it next the sink. She had been quick, we were in no hurry. Great, I thought. After a cold, refreshing shower, I decided to take the time to shave - I hadn't really had time for that in the morning. Checking the watch again, I suddenly, seemingly for no reason at all, thought that I had enough time to also shave my pubic area. And why wouldn't I? In retrospect, I can say quite certainly that I didn't do it because I had plans for what was to come. I just feel more comfortable like that. It made me feel a bit younger, I think, especially next to that sweet girl. I took a look at myself in the mirror. Not to be an asshole about it, but I can say quite confidently that I'm a really handsome guy. Having turned 41 a couple of weeks earlier, I still looked like a man in my prime. Beeing in very good shape helps, I think. I'm very muscular and I've always found it easy to keep a pretty low body fat percentage. My full, dark brown hair and a strong jaw line did their thing, too. I felt good about our trip.

When I emerged from the shower, my towel wrapped around my waist, I found Laura laying on her belly on the big, beautiful couch, reading a book. She was in her white underwear that made her fair skin look even more perfect.

"Time to get dressed, sweetheart!" I said, "I'm starving!"

"Sure, one sec!" she said and immediately ran to her room. My eyes could not help looking at her round, firm ass again as she walked by, and to my big surprise, they found on her right butt cheek a tattoo, that was heavily stylized, but clearly depicted a naked man and a naked woman embracing passionately, very sexually. Hmmh, I thought to myself, you're not the innocent little angel I thought you were. And immediately I felt the sting of a bad consciousness. I very much shouldn't be thinking any of this at all, not even a little, but when Laura came back, she wore a short little black dress that fit her body amazingly and I almost bit my tongue.

The restaurant was amazingly luxurious for a hotel ostensibly dedicated to the more disciplined joys of athleticism, and it was surprisingly big. I heard some violin music without being able to tell if it was from tape or if they actually did have violin players in this place. When the waiter came, I ordered fish, and when it came to the question of drinks, I asked Laura "Would you like some white wine, too?" I knew that Dan and Lynn had a somewhat lenient attitude to their daughter having a glass of wine or something of the sort here and there, even if she wasn't legally allowed to drink, and I didn't plan on making her stay with me more strict in this regard than in her life at home. She happily nodded, as if she had been excited for exactly this situation for a while, and the waiter, luckily, didn't ask us about her age. We talked about tennis for a bit, and we made plans for tomorrow. I hadn't yet seen it anywhere, but from an earlier stay here where she went with her parents, she remembered that the hotel area also had a pool, so she suggested we should go swimming the next day. The thought of seeing her in a bikini or a swimsuit made me squirm a little. All the while I forced myself to keep eye contact, mostly to keep my eyes from wandering down to her cleavage. I don't know how much of that was the excellent white wine, but the prolonged eye contact gave me a strange feeling in my stomach, almost like a sort of vibration. I was pretty sure, however, that she didn't notice the slight nervousness which took hold of me. She talked passionately and surprisingly competently for such a young person about her favorite tennis player, Federer. "It was like witnessing a miracle" she said with regard to his latest game while I nodded in agreement, furtively looking at her small but perfectly round breasts.

When the time to go back to our room came, we were both a little tipsy and walked through the corridors with our arms around our shoulders and kept cracking jokes in the elevator. After brushing my teeth, I went to bed and tried to force myself to think of other women while, under the sheets I started stroking my cock which had been throbbing for what seemed like ages. When all of a sudden, the door opened, I was almost scared to death. When I saw Laura enter my room, I tried my best to hide my erection. She was still wearing her white laced underwear and I couldn't help but notice how beautiful her body was, toned but feminine.

"I just wanted to say good night" she said while I stared at her blankly. She came over to my bed, leaned over, one knee on the edge of the bed, placed one hand on my belly when she leaned over to give me a kiss on the cheek. "Good night, uncle Steve". Her long hair slightly tickled when it touched my chest. Needless to say, once she had left my room, I immediately started jacking off again.

***

As I had ordered, room service brought ous our breakfast to our room. I massaged Laura's neck and shoulders slightly while she was putting butter on her toast. "Good morning, uncle Steve" she said and closed her eyes with a big smile on her face. "Good morning, Laura" I said while my eyes ravaged her. She was wearing a tight yellow t-shirt and black hot-pants. I couldn't help but notice how smooth her white legs looked.

"Did you sleep well?" I asked her, one of my hands still on her shoulder.

"Yes, very well, what about you?" she answered and placed her hand on mine lightly.

"Yes, yes..." I said, slightly absent-mindedly, thinking about the horny dreams that had occupied my night.

"So, how do you feel about going for a swim today?" she asked, reaching around to offer me a bite from her toast.

"Sure, my little mermaid" I said, still chewing. I tried very hard not to think about her in a bikini. I was only in a white t-shirt and my boxers, and anything even remotely resembling a boner would immediately be visible. I closed my eyes and slightly shook my head to get rid of the thought. I couldn't get lost in such fantasies, I told myself, this was my niece after all, but the thought was now crystal clear in my mind: I wanted to fuck the brains out of this girl. I closed my eyes and slightly shook my head to get rid of the thought.

"Wait, uncle Steve" she then said. When I opened my eyes, I saw that she had turned around. "You've got some crumbs on your face from the toast. "Wait, hold still..."

She reached out to my face and softly got rid of the bread crumbs. When she slowly - more slowly and sensually than necessary? - moved her thumb on my lips, I felt a sudden twitch in my crotch.

"Thanks, you're an angel..." I said hastily, "but now let's get ready for the pool!"

We spent most of the rest of the morning splashing water at each other and swimming. The water was a little too warm for my liking, but the pool itself was big enough so that we didn't have to be careful not to bump into some other hotel guest. The pool was outdoors and I had heard in the radio earlier that day that this was supposed to be the hottest day of the year. Laura wasn't the fastest swimmer, but she was exceedingly elegant in her movements. She wore a dark blue one-piece swimsuit, and I was lucky that I took my goggles, because them, I could dive into the water from time to time to peek at Laura's magnificent body. I was trying to make peace with my dirty thoughts: I was just looking, after all. And she was having a blast! All smiles, she told me to hold still and spread my legs while she would dive between my legs, and when I insisted on doing the same with her, I made sure to slightly touch the inner sides of her legs. It made me almost feverishly horny. Another reason that I wished the water was a little bit colder.

"Wanna go sunbathe for a while?" she asked.

"Sure" I said and followed her towards one of several ladders. I waited in the water while she climbed out, and when her ass was on the same level of height as my face, I let my guards slip and remarked to her "That's a beautiful tattoo!" Oh my God, I thought to myself, you fool. But she wasn't offended. Instead, she let out a cheeky giggle.

And then she bent over, slightly pushing her little ass close to my face, and pulled on the back of her swimsuit, making the fabric go between her butt cheeks to expose the full tattoo. Seen from such a short distance, I could see that the stylized couple on her ass cheek wasn't just embracing, but they were touching each other's genitals with their hands. I blushed a little. My little angel has a dirty mind, I thought...

"It's nice, isn't it? A friend made it!"

Was she wiggling her ass at me? The urge to bury my face in it ran through my whole body like a bolt of lightning, and my cock was throbbing.

"It's amazing... Listen, ummm, Laura, I'll swim another round, and then I'll join you by the beach chairs!"

She turned around and gave me a bright smile. "Sure, uncle Steve, I'll wait for you!" Then she giggled again and splashed a little water in my direction with her cute, petite feet. God, I wanted to fuck her so bad, right here, right on the spot. But then I swam out into the middle of the pool, and after some minutes my face had cooled down and my erection was mostly gone, so it was now safe to join Laura without exposing her to my boner. There were probably around 30 beach chairs, distributed evenly around the pool, and I didn't immediately see her. After a while I saw that she had chosen a chair in a spot where there were almost no other people.

"Hello, darling" I said, waiving as I was walking up to her, less nervously than just a moment ago. She was laying on her belly, reading her book again.

"Hello, uncle Steve" she responded in a playfully singsong voice. This girl was cheeky, I thought. Well, if she could nearly push her ass into my face, I could take a little bit of liberty, too. When I reached the head end of the chair and leaned forward to tenderly pat her hair as a second greeting, I made sure that my crotch came as near to her face as I could without being offensive, just to see how she would react. When she smiled without withdrawing her head even for the tiniest bit, I was scared for a second that I would get another hard-on, but I was spared that embarrassement.

"How are you doing? And what are you reading?" I asked as I took a seat on the chair next to her.

"I'm doing great" she said, stretching out the word "grrrrreeeeaat", "what about you?" And then she showed me her book, a slightly ragged copy of Emma by Jane Austen. Smart girl, I thought.

"I'm doing fine, thanks..." I said, slightly mumbling and then leaned back to expose myself to the bright, burning sunlight. After a while, when I was almost dozing off, I heard her voice.

"Uncle Steve?" she asked, "Could you maybe put some sun lotion on my back?"

"Yes!" I almost exclaimed, much too eagerly to sound innocent, "Yes, of course I can do that!"

She smiled and pulled down her swimsuit, unfortunately while half-laying, half-sitting in an angle that precluded me from sneaking a peak at her breasts. She laid down on her belly again, I started rubbing the sun lotion in my hands. As I meant to lean over to reach for her back, she said, "You can, like, sit on my butt if that's more comfortable than bending over."

I gulped and did just what she said, feeling myself pressing against her ass while I massaged her back from her shoulders almost down to her ass. It took me immense strength of will to close my eyes and think of the most mundane household tasks to distract my imagination. I just barely avoided getting a full-on boner, but I have to admit that, when I got off her, the bulge of my swimming trunks must have been visibly bigger than before.

"Thaaaank you" she said cheerily.

***

As noon came, the heat became too much and we decided to go back to our air-conditioned room before we would melt. I'm sad to say that, when she pulled her swimsuit back up, I still didn't get even a glipse of her nipples. Back in our rooms, we quickly showered and then ordered room service to bring us something to eat - today's menu was a Chinese dish with rice and pork and a pretty incredible sauce. We ate in a pleasant silence, and shortly after, we both took a shower. Again she went first, and when I finally could go, I immediately started masturbating, just to shoot my shot so that I wouldn't get hard quite so quickly again. When I came back into our shared living room, I had already put on a white t-shirt and black boxer shorts. I hadn't yet used the nespresso machine, so I decided to treat myself to a big cup of coffee. Laura was lazing on the couch, wearing black yoga pants and a very big pink t-shirt that didn't show off her body, but made her hair color look beautiful.

"Do you want some?" I asked her.

"No, thanks" she said, fixated on her phone for the moment.

The machine buzzed for a while, taking its time apparently. A pleasant, almost hypnotic sound that made me consider a little afternoon nap for a second. When I lead the cup to my lips, I heard Laura's voice.

"Uncle Steve?"

I waited, but she didn't continue, so, after another sip of coffee, I asked "Yes?"

"Uncle Steve? Do you want to paint my nails?"

I took a third sip and then said, "Sure, honey, if you want me to."

She gave me her sweetest smile and said "I really want you to."

I quickly finished my cup and put it on the coffee table. When I took a seat on the couch next to her, she handed me her nail polish of choice. It was a light dusky pink that would sure look good her. I opened the tiny bottle and said, "Your hand?"

She gave me a cheeky smile and acted as if she was eager to hand me a present and had to force herself not to spoil the surprise.

"No, not like that!" she said, her smile veering towards a grin.

"Hmmm?" I made.

"You gotta get off the couch and get on your knees" she said, with an innocent smile.

Now it was my turn to grin. "Why?" I asked.

She giggled lightly.

"Just because!"

Of course I did what she wanted, and carefully painted her nails. I had some experience painting nails for former girlfriends and female friends, but I was a bit out of practice, so I took my time. Just as I had expected, the color really flattered her. I held her hand in mine quite tenderly, lovingly, enjoying the feel of her skin. "So" I said, blowing air on her fingers when I was finished. "Happy?"
