I reached for my drink, telling myself I would look no more, and as I did, she moved up a little. Of course, I looked again. Her movement had pulled her shirt just a little higher. I could now see the leg band of her panties. Her whole leg was now on display for me to look at. Wow! The skin looked so smooth, her thighs so nicely shaped I just wanted to reach down and caress it. I leaned over and took another drink. Big mistake! That pulled her shirt up even farther. I could now see 1/4 of her little panties, and it seemed like they were covering a very nice ass. I could just see the curve of the bottom of her butt cheek, and she had a much more pronounced apple ass than I had ever noticed before. Her panties were white cotton with little blue polka dots. Might have been the cutest sight I had ever seen.

I had totally given up even the act of watching our movie and was completely staring at my 18-year-old niece's perky ass. Man, I realized I had a chubby start. I leaned away from her one more time even though my drink was now empty. She rolled a little more onto her stomach, giving me a fantastic view of one whole cheek and a generous helping of butt crack too. I was trying so hard to stop looking, but the sight was just too amazing. I'm just looking. I figured, I'm not touching. No harm, right?

Well, by this time, I was rock hard, and it was really starting to hurt. Right about the time I thought I should get up and go to the kitchen till I could cool off a bit, Dahlia once again changed position. This time she moved her head around right on top of my crotch.

"What is in here?" she asked, reaching under the pillow. "It's poking my ear."

"Oh Sweetie Don't!" I shouted. But it was too late. She had reached under to move whatever was bothering her and grabbed a handful of her uncle's erection.

"Oh my god! "I'm sorry, I'm sorry!" she yelled to herself. "Ummmm, Was that what I thought it was?"

I was too mortified to think straight. "Let's just finish this stupid movie and forget about it." I sort of snapped at her.

She sat up and moved to her side of the couch, holding her pillow in front of her like a shield. "Oh man!" I thought. "I have screwed things up really badly!"

The movie ended about 15 minutes later. I don't think I even heard or saw a bit of it. When a movie ends, we usually start talking as the credits roll. This time we sat there till the credits ended in total silence. "Well, screw it! "Guess I'll just get drunk since I've probably lost my niece and my friend all with one erection," I thought to myself. I got up and stalked to the kitchen and made my drink a double. When I came out, Dahlia hadn't moved a muscle. I figured she hated me and was disgusted in equal amounts. So when she spoke, I was more than a little confused.

" I'm sorry, Uncle Amias. "I am SOOO sorry." Her voice was soft and sounded like she was fighting back tears.

"What? Dahlia, you did nothing wrong! It was all my fault. Why are you apologizing?"

"Because I touched your... thing, and now you are mad at me."

"Oh Sweetie! That was not your fault, and I'm not mad at you. I was mad at myself and ashamed of myself."

"Why?" she asked me, sitting up and finally looking at me. My turn to look away now.

"Because of the... condition I was in" I answered lamely.

There was perhaps 1 minute of silence when she finally asked "why was it hard?"

Great! Not the conversation I needed while drinking. "Well Dahlia... When a man gets aroused, his, um, penis enlarges and..."

"Not that!" she shouted out sarcastically and condescendingly like only a young adult can. "My mom had "The Talk" with me, and we learned about it in health last semester. Plus I do have friends, you know? Who has had sex before and the males have erections? I mean, why was yours hard? "We were watching a lame kid's movie."

I have always talked to her like an adult, and I have made a point to never lie to her, so I decided I wouldn't start now. " I don't know if it was the drinks or maybe just that I haven't dated much recently but... I... Well... Ok, I'm not going to blame anything but just plain me. We were sitting here ..... And your t-shirt had pulled up... and I had never noticed how nice your legs are... and I could kind of see your panties... and a little of your butt...and I wasn't meaning to look...and I would never touch you inappropriately or anything...and I didn't mean to think about it... but. "I'm sorry." I stammered out like a nervous boy.

She was really quiet and looked about to run away. "You mean you were looking at me when that happened?" she asked quietly and kind of hesitantly. "It was like that because of me?"

" Dahlia, I am sooo sorry! It will never happen again! I won't do anything like this ever again. Please don't be mad at me....... "I don't know how to make this better between us, but I feel horrible." I was near tears. I felt so guilty. We both sat there looking at the blank T.V. screen for quite some time. I figured she was deciding whether or not to call her mom to pick her up or call the cops on her perverted uncle. She said something so quiet I didn't even hear her. "What D.....?"

In a quiet, shy voice she had never used with me before, she said almost into her pillow, "I said... you can look at me some more if you want to."

I almost fell off the couch! There is no way that she actually just said that. "Why would you say that?" I asked.

"Well, when you said that you got a... well you know, because of looking at me, it made me feel kind of special. Pretty I guess. It felt good to know you liked seeing me that way."

"Honey" I said. "You don't have to let me look at you like an old perv for me to tell you how pretty you are."

"But you had never looked at me that way before you saw my panties... I want you to look at me and see what you think."

By this time, she was having a hard time looking at me. Her face was pink from blushing, and I could see her hands trembling. She stood up from the couch and walked in front of the now blank T.V. I knew I better put a stop to this before it got out of hand. "Dahlia! You don't have to do this. I think you are a very pretty girl."

"I know I don't have to do this. You would never let me do anything like this. "I trust you, Uncle Amias. "I want to do this." She looked at me for a moment, as if she was looking for a response. "Do you want to look at me?"

I was stunned I knew I should say no, but all I did was look at her and nod my head.

Dahlia reached down and grabbed the bottom of her t-shirt. Hesitated a bit, like she was debating if she should really do this, then pulled it slowly off and dropped it next to the couch. She was wearing white cotton bikini underwear with little blue dots and a matching bra. The panties and bra both had little blue bows right at the front. They were not meant to be sexy, just a cute combo that any teen could buy at any store, but right then I thought they were sexier than anything that Victoria's Secret had to offer. She was just standing there, looking down, sort of fiddling with her hands. Her cute little figure was just there for me to stare at. She started to turn around slowly so that I got a good look at every side. Then she did something I wasn't expecting.

After her first turn, she reached behind her and started to unhook her bra. I couldn't have turned away if a car had driven through the living room wall. She got it undone and slowly pulled down the straps while keeping the cups in place. This wasn't some sort of dance or strip tease. This was an embarrassed 18-year-old girl letting a guy see her boobs for the very first time. She pulled the bra away and let it fall beside her discarded shirt. Damn! It was a beautiful sight. Her breasts were not large but more than I had realized she was hiding. Probably a full A cup (32A I later found out) that was perfect in every way. They were small half domes that sat high and firm with no idea what the meaning of gravity was. Her areolas, almost dead center, were the size of quarters and a dark pink that made them stand out from her pale skin tone. Although it was quite warm, both were capped with small nipples that popped out and hard. They had a small amount of freckles over them that just added to the complete cuteness of the whole package. When she started to move a little, they hardly jiggled. So firm and perky, I wanted to jump up and take them in my hands and kiss them.

I let my gaze wander down her body. Her stomach was as flat as a board. Her waist was tiny, and bloomed out to well-shaped hips. Small, but perfectly in proportion to her small size. Her legs were lean and muscular.

Then she surprised me again. Her thumbs came down and hooked the waistband of her oh-so-cute panties, and she bent toward the floor and stepped out of them. At first, I thought that she either shaved, or had yet to grow hair down there. However, at second glance I could see light blond wisps of mostly straight, downy soft hair in a triangle that was hard to take my eyes off of. I looked up to see that she was slightly smiling, but her face was no longer pink, it was bright red in her embarrassment. She started to turn around again, (I think to avoid eye contact as much as letting me see everything.) When she was facing half away from me, I started seeing the best part yet. Her well-toned backside was sticking out from her petite frame by a couple of inches. When she had her back to me, it just got better. A perfect heart-shaped ass!

Let me say I have always admired a well-formed ass. I have looked at them with pleasure since the day I knew I liked girls. I have seen a great many in my day, from girlfriends to strippers, porn stars to swimsuit models, athletes to random girls on the street. I could go on and on about the merits of a firm, perky backside. My cute little 18-year-old niece's butt beats them all hands down! I know that there are many differing opinions between men about girls' butts, but there are some that are universally admired. This is one of those. Her legs went up and made a perfect ass of themselves. The holy grail of butts. Dahlia runs almost every day. She loves to hike, bike and even started working out at the gym with her track team this year. Even when at my house, she often rises before me and runs two to three miles. Her muscular butt is the trophy she gets for all this hard work. If you have never looked at a girl's track and field star from behind, I really suggest you try it. And right here, 5 feet in front of me was the nicest ass I have ever seen.

I really don't know how long I sat there. Dahlia did 2 or 3 slow spins and then stood still. 3 minutes 30 minutes? No idea how to tell the truth. I'm not really sure whether I even breathed. Dahlia let out a little giggle, and I was so glad to hear it that I snapped out of my trance. "What is it?"

She was looking down at the front of my shorts, where I was sporting a pup tent with the added bonus of a small wet mark. " It looks like it happened again," she said happily.

I was speechless as she was still standing there with nothing on but her rainbow slippers and a blush. "Well?" she finally asked. "Do you think I'm pretty?"

"Oh my God, Dahlia! "You are so far beyond pretty, I'm not sure that there is a word for it!" I replied without ever looking away from her beautiful nude body. "You are damn near perfect!"

She broke out in a huge smile that could have lit up the sky, her blush faded, and she stood up a little straighter, her breasts pressed out a little more confidently. She seemed to have totally forgotten that she was standing there naked. She looked both proud and extremely happy. "Oh Uncle Amias, do you really think so?"

I stood up from the couch, "Have you ever known me to lie?"

"Thank you!" She ran the 2 steps and jumped into my arms! I was standing there holding a gorgeous young adult without a stitch of clothes on. I held her close for a minute and whispered in her ear. "Thank you for letting me see all your beautiful secrets." I put her down on the ground. "Now I think you better get upstairs and get ready for bed before things get even more awkward." And without thinking, I gave her a soft playful slap on her bare rear end.

She looked me right in the eye and winked! Then let out a playful "Ummmm". She then turned and right in front of me she bent over and picked up her clothes. That wonderful ass in clear view. Then she slowly walked over to the stairs and turned for one last view of her breast. " I'll call when I'm ready for bed."

"Just go you little exhibitionist!" I half shouted, half laughed. And I'd be damned if my little, shy, innocent niece didn't wiggle her ass at me!

Well... with a smile that bright I figured I hadn't screwed her up too badly. I mean come on, all I did was a little harmless looking, right?

I grabbed the dirty dishes from the coffee table and took them into the kitchen. "OK you old perv," I said to myself. "That's it! "You had your fun looking at a young girl, but it stops right there!" I put the dishes in the sink and grabbed a glass of cold water. I kept thinking about that perfect petite body. I felt like I should feel guilty, but why? I didn't ask her to strip. I didn't molest her. She seemed so happy when she went up, and really didn't seem bothered by what had happened. Sure, I was going to masturbate like crazy tonight, thinking of my lovely niece, but what's the harm in fantasy? I guess I felt bad about not feeling bad.

After finishing up the dishes, a call came down the stairs."Ready for bed!"

I climbed the stairs and headed into Dahlia's room. I admit I was a little let down to see she had her nightshirt back on. I walked over, grabbed the sheet to pull it up when she stopped my hand. "Thanks for making me feel so special tonight."

"It was my pleasure Sweetie! But you know, we probably shouldn't have done that, and we definitely had better keep that secret to ourselves."

"I know that Uncle Amias, but I still enjoyed it." She was looking at me like she had something to say but didn't know how. "Is something on your mind?" I asked.

"Uncle Amias... Would you get mad if I asked you for something?"

"Of course not!" But that doesn't mean you will get what you ask for."

She looked at me for a minute looking for the words. "Would you teach me how to kiss?"

"You have never kissed a boy? Not at school, or summer camp, or on the track bus?"

"Nope. Most of my friends have. Sometimes they make fun of me because I never have. They call me prude. But I think that you would be a good guy to show me how."

'Oh! Great! Now what am I going to do?' I thought.

"Honey, I'm not sure whether that is such a good idea. I'm your uncle, and that's not proper. Plus, I'm older than your own mother! "Wouldn't you rather do that with a boy your own age?" I knew if she wanted me to I was going to do it. I was hoping she was going to back down.

"No. I want it to be with someone who I trust and won't make fun of me if I do something wrong. Even though you are my uncle, you are also my best friend. Besides, we weren't being very proper earlier, were we?" Well... she had me there.

"Are you sure?" I asked. "I would hate for you to do something and then feel bad about it later."

Her face lit up with that million-dollar smile again. "I'm sure!"

"OK, sit up". She sat up straight in bed while I sat next to her. "First thing is to just be comfortable. Put your arms around my neck and I will put mine on your waist. Don't overthink what you are doing; just let your body do what feels right. Now I'm going to lean in and kiss you, just feel the moment and relax. When our tongues meet, we just slowly explore each other and go with it. Most of all, enjoy it. Kissing can sometimes be the most passionate part of a relationship."

Last chance to back out, I thought. Then it was too late. I leaned forward and softly met her lips. They were full and soft and felt incredible against mine. I didn't rush to open my mouth, just enjoyed the soft lingering kisses she was giving me in return. At about the same time, our lips parted, and our tongues crept into each other's mouths. As most first kisses go, there was a short adjustment period. First she was a little timid but soon began getting a little more aggressive. We closed our lips to finish, just to start again. Her hands tightened on my neck, and she started rubbing my neck and the back of my head. My arms pulled her closer and started caressing her sides. I pulled my lips away just enough to take her lower lip in my mouth and softly nibble and suck on it. When I did, she gave a sexy sigh. My thoughts disappeared, I was seeing bursts of light behind my eyelids. I didn't think of right or wrong, just how this moment felt. My hand moved around and cupped her right breast. She pulled back just a bit and gave a sharp gasp. "Yes!" She half whispered, half moaned into my open mouth. Then she took her turn pulling on my lower lip as I rubbed my thumb across her nipple. I could feel her soft sighs as they went right into my open mouth. I squeezed the breast I was holding while I moved my hand in small circular motions. This made her moan even more into my mouth. Our tongue's were dancing circles around each other, and our bodies were trying to pull closer than they already were. Her hands were in my hair, pulling my open mouth harder against hers. I knew if I didn't stop now there would be no stopping. I started to lean back a bit, but she leaned towards me. I finally put my hands on her shoulders and gently pushed her back, loving the small whine she gave at our parting and giving her one small last kiss just as we parted.

"Wow". That's all I could say. I leaned over, resting on my arm. "Really WOW"

Dahlia was a little glassy-eyed but smiling widely "That was awesome! If I had known it was that much fun I'd have been begging boys to kiss me for years. Does it always feel so good?"

"I told you a kiss could be passionate." I replied, "Sometimes two people just really click when it comes to kissing. I'm pretty sure that there is no more "teaching" I can give you. That one got you an A+ for sure."

She was giggling again, and pointed at my shorts. "I can see that. "Looks like I'm three for three." Sure enough, I had a rise in my shorts that was undeniable. "Can I see it? I've never seen one before."

"Never? You live in the internet age!?! You have never seen a penis?"

"Well, babysitting with Ashley, we have to change her baby brother, but I don't think that counts. And both of us have laughed about the male horses out back... it looks like they have a guy trapped inside reaching his arm out!"

I had to laugh at that! "Yeah, I guess I fell somewhere between a baby and a horse in the size department. "Dahlia. You are a really young girl. I don't think you should be seeing your uncle's penis."

"Should my uncle be looking at me naked?" She shot back at me. I had to look at her to see if she was mad or just playing. She didn't seem upset.

"You got me on that one. So is this considered extortion or blackmail?"

"Why don't we just say a favor returned?" she said, smiling.

I stood up from the bed without any more thinking. I untied the gym shorts I was wearing and lowered them down. When my hard dick slipped free from the waistband it sort of bounced back against my body. Dahlia's eyes were glued to my crotch. "Whoa, it's so big!" I almost laughed out loud. It's the kind of thing a girl says to make a guy feel good about himself, but I could tell she really meant it. In truth, my size is quite normal, kind of big around, but a little on the short side if you ask me. But what guy in his right mind is going to tell a beautiful girl that?

I stood there and let her look for a minute or two. "So how long will it stay like that?" She asked without looking away from my crotch.

" Probably till I go to my room and can masturbate" I replied honestly.

"OK, but not until you kiss me just one more time. "You know, just to make sure I got it." She said this in a way that I knew she was just using as an excuse but since I didn't see much harm in doing what we had already done, I agreed.

"OK, but just one kiss."
