I had just turned 18 two months ago and now that I was ‘mature’ enough, my parents had decided I could stay home while they went on a second honeymoon. Of course I was ecstatic! I’d never been a very popular girl, but I did see it as the perfect time to bring a few guys home! Plus, I was dying to have some time alone in the house without my parents, they could be quite controlling and this was my chance to be naughty for once!

There was a catch, however. My Uncle Andy would be coming over to keep an eye on me and the house. Well, that was the excuse this time. Apparently his girlfriend had kicked him out again and this was an excuse that my dad could use to let him stay with us for a few weeks. He wasn’t really a bad guy, and was actually quite good looking for 47, but it did sadden me a little to realise I wouldn’t be as alone as I’d hoped.

Let me tell you a little about myself, my name is Tammy. The reason I’m not really popular is because I’m a bit of a slut. It’s not because I’m really hot or anything, but because I put out. I’m tall, maybe 5’6, with medium length wavy brown hair, blue/green eyes and small but seductive lips. Now I am a big girl, about a size 28, so my breasts are large at a size 28E. I also have a bit of a belly and my arse is quite perky and round.
Although they don’t admit it, guys my age seem to like my body. But what I really like is guys that are a bit older. Truthfully I have a bit of a fetish for older men, even really old men in their 50’s or 60’s. The oldest guy I had ever been with was 32 years old, but it didn’t last because I never got time to be with him. I had never gotten much privacy from my parents so most of my sexual adventures to date had taken place at school or in a car.

My parents planned to be away for 3 weeks and the night before they left my uncle arrived. As usual, he had all his worldly possessions in the few bags he brought with him and, like always, was given the room next to mine. We had a bathroom joining the two rooms so I would have to share with him while my parents were away. I hadn’t seen my uncle in a few years now and as we all ate dinner together I was given a chance to really look at him. He was in his early 40’s but he still looked young and cheeky. He had short brown hair that kind of stuck up and flopped over his head, brown eyes and a strong defined face. He was taller than me and a little chubby, but I could still make out his muscular chest and arms.

I also noticed during the dinner Uncle Andy was looking at me too, probably surprised at how much my body has matured since he last saw me. I was wearing a thin strapped summer dress that covered most of my body but made my breasts stand out like mountains. His eyes drifted over my body and when I stood to get a glass of water his eyes widened appreciatively at my arse and legs. I smiled at him and was surprised at myself for liking the way he looked at me. I knew I liked older men, but I had never thought of my family members that way.

That night before bed I quickly took the secret dildo I had out of my bathroom and hid it in my bedside drawer, the last thing I needed was my uncle to find it and my parents to go ballistic! I always slept naked and as I lay in bed, absently stroking my bare pussy lips I couldn’t help but thinking about the way my uncle had looked at my body. It turned me on having him look at me like that and for some reason, it was even more exciting to think that my own uncle was looking at me like a real woman.

I spread my pussy lips with my fingers and gasped as I lightly touched my sensitive clit, it was already swollen and I felt a little guilty that it was my own uncle causing the arousal. I had always been quite sexually aware, and self pleasure was something id become good at.
I heard the bathroom door open and close. I lay still in my bed as I heard my uncle in the bathroom right next door. I heard him turn on shower and I resumed rubbing my clit, sliding a finger in my slit and using the juices that escaped to further dampen my clit. I was soon moaning softly as my finger fucked my wet pussy harder while my free hand felt in my draw for my dildo. It was about 8inches long but quite thin. I moaned as I grabbed it and wasted no time in sliding its length deep inside my cunt. I was so turned on by my own uncle and the fact that he may find me sexually attractive.
lost in my own pleasure, I didn’t notice my door to the bathroom creaking open. My legs were spread wide and my naked body made fucking motions as I thrust onto the fake cock. I was suddenly overcome by wave after wave of pleasure as I imagined my uncle’s cock filling my mouth with hot sperm. I thought about how he would fuck my mouth and talk dirty to me as I came hard, my pussy clutching and squeezing the dildo.

I lay on my bed panting for a few moments before I heard my door click closed. I opened my eyes surprised to see nothing, but then heard my uncle finally exiting the bathroom. I realised that I must have been loud enough for him to hear me and I silently panicked at the thought of what he might have seen.

The next morning my parents left early and I awoke to the smell of bacon and eggs. I quickly showered and dressed skipping down the stairs to be greeted by a smiling Uncle Andy and a plate of hot food.

“Morning sweetie,” My uncle said, “I cooked! I figured while I’m here I might as well be of some use.”

Laughing I took the plate of food and sat happily at the table to eat. We chatted lightly while we ate, mostly about school and how much I’ve grown since we last saw each other. I was glad he didn’t show any signs of what he had seen or possibly heard the night before, even though I had hoped deep down that he had liked what he heard.

“So Tammy…” Uncle Andy smiled, “How did you sleep last night? I hope I didn’t disturb you with my late shower?”

I instantly blushed, fully aware that my uncle had watched me masturbate last night. Crap, I thought, So he really did hear.

Looking down at my plate I hesitated before replying, “No, that’s ok, How was your shower Andy?”

“Tammy, please! Call me Uncle Andy.” He spoke sternly, but I saw a hint of a smile on his lips as he blatantly looked at my large breasts over the table.

I had chosen to wear close fitting jeans and a pale button up shirt. It was a little tight and the buttons stretched just enough to let him glimpse my white bra underneath. I loved this top specifically because it, along with my bra, allowed my dark saucepan nipples to be visible through the sheer material.

“My shower was great thanks, very……satisfying.” My uncle smiled knowingly and my blush deepened. He knew I was caught and he was teasing me about it!

The day went on like this. Flirty banter from my uncle mixed with teasing and blatant hints at what he had seen. After a while I relaxed into the playfulness of it, hopeful that he would not tell my parents. I also found myself getting aroused by how he seemed pleased at having caught me masturbating. I started to tease and flirt back with him, making excuses to bend or arch my body and exposing myself just enough to give him quick glimpses.

I was surprised by the way my own uncle seemed to flirt with me, even encourage me to display myself to him. He would ask me to reach up and grab things for him or tell me to bend over in front of him to check something on the floor. As surprising as it was though, I was more surprised at my own arousal. My pussy was damp all day and I couldn’t wait to play with myself again!

Once again that night I took out my purple dildo and took it into the bathroom with me for a shower. Knowingly, I left both bathroom doors unlocked as well as the shower curtain, hoping my uncle would want to take another peek. I washed myself as usual, lathering up my breasts and bare pussy with soap before thoroughly rinsing myself. I did the same with the dildo, sucking on it when it was rinsed and moaning softly as the smooth shaft entered my mouth. Behind me I heard the door creek and I had to stop myself from turning, I knew uncle Andy would be there watching. I wanted him to watch me and I wanted him to know it.

I leaned into the corner of the shower, turning down the force of the water so it just tricked hot water down between my breasts and pussy. The dildo was now warm with the water and I slid it along my wet slit, gently pushing aside my puffy lips as I made sure I was facing the doorway. I lifted a leg onto the tiled ledge and spread them apart so I had good reach to my now aching cunt. The dildo was soft and warm against my pussy as I teased open my lips, pressing the head of the cock to my fuck hole. I moaned softly as I pushed the dildo up into my pussy. I smiled as I felt it stretch the walls until it was as deep as I could get it. I held it there inside me, panting as I rubbed my clit with my free hand.

Slowly I started to slide the dildo out of my pussy. I gasped as I shoved it back in and the force caused a satisfying slapping sound against my mound. I heard a soft bang from behind the door and as I looked up I smiled to see a shoe sliding back to hide behind it.
I tried thrusting the cock into my pussy faster, arousal taking over with the knowledge that my own uncle was again watching me masturbate.

After a few thrusts I was became frustrated because with the trouble I had balancing in the running shower. So, with a big grin for my uncle, I slid the cock out of my pussy and stuck the suction cup onto the ledge. I positioned myself above the dildo and stroked it before sliding my cunt slowly down the full length as my hand rubbed my clit hard. In this position I was able to ride the cock, I fucked it faster with each stroke as my large round ass slapped against the cool tiles.

I was lost in my own pleasure and as I began to moan louder my 28E tits bounced against my chest as I roughly rode the sleek dildo. I heard muffled noises at the bathroom door and I couldn’t help but moan louder and pound my pussy onto the cock harder. I wanted my uncle to know how much I wanted him; I was so aroused I didn’t care if I got into trouble so I began to moan his name.

“Mmm Uncle Andy…Mmm you like my pussy uncle Andy? Oh yes fuck me please Uncle Andy!” I couldn’t help but moan at my own words as I felt my orgasm build up inside me and explode out of my cunt.

My whole body shook and trembled on the dildo, hurting my insides a little as I bounced up and down with the force of my orgasm. My large breasts swung in front of me slapping against my chest and adding more pleasure. As my orgasm subsided, I stood shakily, still impaled on the dildo as I turned up the water and let it wash over me. I slid my cunt up and down the shaft of the dildo slowly and enjoyed the sensation of being stuffed before I finally let it pop out of my cunt so I could finish off my shower.

Just like the night before I heard the bathroom door click closed and I wondered what would happen tomorrow. I knew for a fact that my uncle watched me masturbate, and I hoped he was jerking his cock too. But would he tell? Would I be in trouble for such a display?
