Since I rarely use the forums, I'll share a short story that will totally make your d*ck stand up. XD
So kids, go to sleep now. This is not for you. XD This was created by my friend: CoDe4 (CD4) or 21007.
I will use Ariana Grande as the girl in the story, coz I just like her. 
It was a classic case of teenage stupidity. Ariana Grande and her friends had gone out shopping at the mall, and while there thought it would be amusing to see if they could get away with stealing some clothes.
Naturally, the store detective had stopped them on the way out, and the next thing they knew they were in the back office being questioned by the authorities while waiting for the police to arrive. Fortunately for them, the officer in charge recognized who they were, and taking pity on them, gave them a stern warning before driving them home.
I had been staying at the house for just a few short days, with intentions of seeing out the weekend before saying goodbye to the family and heading up the west coast to my home in Petaluma. It was sheer luck that Ariana's folks were out visiting family across town when she arrived home with the officer.
"What's going on?" I said answering the door.
"Are you a parent or guardian?" the female officer asked.
"Yes. She's my niece." I replied. "Her folks will be home in a few hours."
The policewoman then went on to explain what had occurred and how Ariana would be made to pay a substantial fine.
"Well, thank you for bringing it to my attention." I said. "I'll let her mother know."
"Please do." the officer stated. "Miss Grande and her friends got off very lightly in my opinion."
"No, you're right. Thank you again."
Without saying a word, Ariana pushed her way by me and marched up to her room as I waited for the officer to leave before I shut the front door and followed my troublesome niece upstairs, knocking on her bedroom door and waiting for her to answer.
As expected she did not respond, but nevertheless, I helped myself inside.
"Hey! Get out!" she exclaimed, as she swiftly dashed from her position at the window and attempted to put out her cigarette.
It seemed on top of everything else, I had caught her smoking in her room.
"Wow." I laughed. "This just isn't your day today, huh?"
"Leave me alone!" she exclaimed. "It's got nothing to do with you, Uncle Mike."
Obviously I refused to leave, and as I shut the bedroom door behind me, I turned to see her spray air freshener around the room, trying to disguise the scent of cigarette smoke. I had to laugh at her futile attempts, but more importantly, I took the opportunity to notice her outfit, or lack thereof.
It seemed Ariana had changed into something more comfortable, which now consisted of a tiny singlet t-shirt and lace boy shorts. With her makeup still on and her long fuchsia-red hair tied back into a ponytail, caused her to look considerable older than her actual age.
Noting this, I was sure that in her current state her mom would definitely disapprove of her current attire, and moreover my presents in her bedroom considering how "naked" she was. It was then as I stood contemplating this that I inadvertently found myself glaring directly at her erect nipples.
It was either very cold or she was extremely excited about something.
"So... are you going to tell mom?" she bluntly asked me.
"Tell her about what?" I quipped, "About the smoking or the shop lifting?"
Ariana simply rolled her eyes as she wandered back to the window to help herself to another drag of her cigarette. It was evident to me that she couldn't care less about what I thought, or what I might say to her mother. I guess she just assumed I was a push over and that she could flirt her way out of it.
She was wrong... for the most part.
"What has gotten into you lately, Ariana?" I said as she confidently blew out the cigarette smoke. "Are trying to provoke me?"
"No." she giggled. "Not at all."
"What is it then? Are you trying to become the next Lindsay Lohan?"
"Don't be ridiculous, Uncle Mike. I'm just having a little fun. Didn't you have some fun when you were my age?"
"Yes, but..."
"But what?" she interrupted. "I supposed it was OK for you and mom to make mistakes when you were young, but not alright for me?"
She had a point. And when I thought back to how her mother, my sister, used to behavior at her age, Ariana was practically angelic compared to her.
"Come on Uncle Mike, can't you just keep this between us?" she said in a little girl voice. "Mom doesn't have to know anything?"
She was turning on all the innocence and charm she could muster, and for a moment I actually considered letting her off the hook. Dressed the way she was and looking as good as she did, it was so very difficult to say no to her, but at the very last moment I saw through her ruse.
The little bitch was actually trying to flirt her way out of it.
Just then, Ariana turned to put her cigarettes away in her desk drawer, and as she bent over she intentionally flaunted her tight round butt at me, making my eyes grow wide and my cock twitch in my pants as I detected the visible camel toe.
"Jesus Christ." I thought, as I noted just how incredibly tight her panties were. The almost seemed painted on!
I could practically make out every groove of her teenage vagina.
Damn she had a hot little box on her, not to mention a tight athletic body, and she sure knew how to use it. Ariana might have been incredibly naïve, but she was sure intuitive. She full well knew the affect she was having on me, and instead of being shrewd or embarrassed about it, she seemed to encourage my leering.
Pausing for a moment, a lewd thought suddenly crossed my mind as I began to wonder if she in fact was still a virgin. Watching her saunter around the room half undressed, I suspected she was not and the next series of images that filled my mind involved thoughts of her engaged in various sex act, and positions.
I started to wonder how she had been taken her very first time, and how many times since then had she had sex. I even began to wondered if she enjoyed giving and/or receiving oral, and if she had been adventures enough to try something as daring as anal.
Judging by her recent behavior, something told me that nothing was off limits for her. This notion in particular really excited me. It was during this time that I shook my head and felt ashamed of myself, which in turn only strengthened my resolve.
I hated her for making me think this way, and I intended to pay her back in spades.
"Are you kidding?" I snickered. "Keep this between us?"
I added. "Of course I'm going to tell your mother everything! What kind of brother would I be if I didn't tell her what her wayward daughter was up to?"
"But Uncle Mike!" she whined.
"Sweetheart, there is no excuse for what you did today." I told her. "It's pretty damn serious. I mean you're a goddamn television star now. You have no excuse."
Ariana pouted, as my eyes immediately drifted to her chest once again and to my surprise her nipples seemed to strain even harder than before. I couldn't believe the size of them. They were the size of pencil erasers, and dark in nature.
She had to know how obscenely erect they were.
"You're just lucky that cop was a fan of the show." I reminded her. "Otherwise we wouldn't be having this conversation, and you'd be sitting in a holding cell right now."
I knew that that part was probably untrue, but I wanted to scare her a little, keep her off balance.
"No, you did a very bad thing." I went on. "And I'm sure your mother is going to punish you severely for it."
I let the words sink in, and watched as her eyes began to well up in tears as she realized that she would be receiving no mercy from me. I waited, watching her get more and more anxious, before I spoke again.
"Unless of course..." I trailed off, as if I was contemplating something.
A spark of hope blossomed in my nieces dark eyes.
"Unless what? Unless what Uncle Mike? Tell me?" she pleaded.
I suppressed the smile that wanted to give away my serious face.
"Well... I suppose I could punish you here, right now, myself?"
Ariana looked confused.
"I know what I would do with you if I were your father, and if you're willing to take your punishment, then maybe your mother doesn't have to know."
"You're going to punish me?" she giggled.
Once again she apparently assumed that I was a push over.
"How are you going to punish me, Uncle Mike?" she added seductively.
"Well, in my opinion I think you need to be spanked." I stated, looking straight into her eyes to let her know how deadly serious I was.
Ariana was expressionless.
"I know your mother would probably take away your car, or ground you for a few days, but I'm of the opinion that a few smacks across your butt would go a lot further toward making you think twice about the consequences."
I could tell from the grin on her face that she still thought I was just kidding. But her smile eventually faded away as she realized I was not joking.
"But it's your choice, young lady." I continued. "You can either take your punishment from me, here and now, or we can wait for your mom to arrive home and I tell her everything."
I let her ponder for a moment as I took a seat on the edge of her messy bed.
"So, what's it going to be?"
She lowered her gaze in shame and after several moments of silence finally whispered her answer.
"Spanking..."
"Excuse me?" I stated loudly. "What did you say?"
"Spanking." she repeated meekly. "You can spank me, Uncle Mike."
I felt my cock twitch in my pants at the mere notion.
"OK, come here." I instructed in my best authoritative tone. "I want you to lie on your stomach across my lap."
Ariana shrugged her shoulder before she put down her cigarette and slowly wandered over and moved into position, lying directly across my lap with her butt in position. It was only now that I admired how intricately pretty her red lace boy-shorts were.
They were almost see-thru.
Beneath her belly I was sure she could feel my raging erection. A shiver of anticipation crept over me as I realized that she had relinquished all control over to me. Was I really going to take advantage of her in this way? I mused.
I was conflicted and confused, but also incredibly aroused beyond belief.
Placing my hand on the small of her back, I reveled in the feel of her soft tender skin and the roundness of her butt. My eyes glazed over with lust, as I moved my hand gingerly down the length of her body and rested it on the back of her thigh, feeling her warm flesh.
She was hot to the touch.
I was amazed by her naivety, and expected her to stop and resist me at any time, but she never did. Instead she simply played along and seemed eager to please. Slowly I slid my hand upward and I let the palm of my hand rest on the cheek of her right buttocks for several moments, my breathing shallow, reveling in the sight and feel of my niece's supple skin.
"OK, so I'm going to give you twenty swats." I explained. "And I want you to count each of them out to me."
Just then, a devious thought crossed my mind and I immediately added, "Also, I want you to thank me for each one. Do you understand?"
"Thank you?" she protested.
After that I rested my hands on her generously sized backside. And slowly moved my hand inside towards her thigh
I could feel her trembling with excitment beneath me. I decided, it was time to flip her over and lay her on the floor.
I began to move my hands up and down her tender body as she moaned quietly. As this point we were both covered in sweat, and I decided to remove her shirt
Her breasts were much more bigger than I thought. They were shiny after all the sweat that was pouring down. I began to wrap my tongue around her nipple. I couldn't get enough, it tasted very sweet but also a little salty because of all the sweat. As I did this, I felt her delicate lips gliding across my neck. I can smell her perfume as she leaned over me.
Then I banged her.
