Since I can remember, I always had a huge crush on my aunt, Lucrecia. She was born in Madrid, and had come to the States with my uncle Mike when he was in the Navy. When I was much younger, my mother disappeared, leaving my father to raise me. Since his work often took him away, I spent much of my time growing up, with Tia Lucy.
We had a special relationship, which I guess I can only describe as the type that sometimes develops between a younger man and a mature woman. Perhaps it was a cultural difference between my Tia and the rest of the family, but she was very open-minded; she always told me that I could talk to her about anything...which I often did. I owe much to her caring insight.
The summer before I started college, I was visiting my aunt and uncle in their home. My uncle was gone to work for the day, and I had decided to clean the garage for him.
After sweeping the floor and hanging his tools, I turned my attention towards his work bench. Pulling a drawer open, I was about to fill it with a handful of small tools scattered on the bench, when I discovered, quite by accident, a magazine at the bottom with a picture of a naked man kissing a fully clothed woman on the cover.
I hadn't known that my uncle looked at books like that. Alone in the garage, I glanced back at the closed door leading into the kitchen. I could hear the sound of the vacuum in the living room, and knew I probably had some time.
Laying the magazine on the bench, I flipped it open, feasting my young eyes on pictures of fully-clothed women in various poses with totally nude men.
One of the darker-skinned models reminded a little of my aunt. She had jet black hair that reached her waist and deep, brown eyes. Her tits were enormous, just like my aunt's, packed under a tight sweater that stretched across them.
In the picture, the model was standing in front of a naked man who was holding his hard cock in his hand. She smiled down at it.
Like any young man, I'd thought about my aunt hundreds of times, making her the subject of many of my masturbatory mind-movies. She was a decade and a half my senior, but still hot as hell. She usually dressed to show off her curves, and it was hard not to stare, sometimes, at her enormous cleavage spilling over the tops of her low-cut shirts and dresses.
Opening my jeans, I quickly took my swollen cock in hand and stroked, looking down at the picture on the workbench. The contrast between the nakedness of the man, and the fully-clothed woman was so different, so hot.
I imagined that it was me in the picture, standing completely naked in front of my full-clothed Tia Lucy, stroking my hard cock while she smiled down at it.
Pulling on myself, I flipped the page over to the next picture. In it, the same models had now changed positions. The naked man was squatting, knees wide apart, as he stroked the length of his huge, hard cock. The fully-clothed woman bent forwards over him. Her giant breasts hung in his face beneath her sweater.
I saw my Tia in the same pose, her huge, sweater-covered tits in my face, as I jerked, squatting totally naked in front of her.
"Sobrino?" my aunt's heavily-accented voice suddenly ripped me from my fantasy.
My back faced the door. Turning from the waist up, I twisted to look at her, cock still in hand, trying to hide it in front of me.
Tia Lucy stood on the doorway looking at me with a concerned expression. Her hair was pulled back into a long ponytail. She was beautiful.
"What are you doing?" she asked worriedly, "are you okay?"
With my heart pounding in my chest, I struggled for something to say. My gorgeous aunt had just caught me jerking off to a mental picture of her...although I was sure she couldn't actually see what I was doing.
"Just cleaning up the garage Tia" I answered meekly, hoping she would buy it.
Standing a moment, she took in my strange position, while I sweated bullets. Her eyes fell to the magazine on the workbench.
Then, what looked to be the light of understanding spread across her lovely face.
"Okay querido," she said, smiling sweetly, "dinner will be ready when you are finished." With that, she closed the door.
I was in shock. I had just come about as close as you can come to being caught. My heart raced, and I was trembling. Judging by her reaction, I didn't know for sure if she knew what I was doing, but I had a pretty good idea that she had figured it out.
Stuffing my still-hard cock back into my pants, I put the book in the drawer and went in.
Tia Lucy stood by the sink, washing the dishes when I came through the door. I'm sure I was red-faced, but tried to act normal. Turning her head, she smiled at me. "Hi," she said, "did you have fun?"
"Huh?" I stumbled, shocked.
"In the garage, sobrino," she laughed, now standing to face me with her hands on her hips. I noticed again how large her breasts were. "Did you have fun cleaning the garage?"
"Oh, yeah," I mumbled...maybe she didn't know after all.
"Well, dinner is ready now, go wash," she said in her thick accent. Smiling, she turned back to the dishes.
Still feeling embarrassed, I hurried down the hall to the bathroom, relieved to be away from the subject for the moment.
My uncle came home, and we sat at dinner.
"Who cleaned the garage?" he asked happily.
"Your nephew," Tia Lucy answered, smiling with a wink at me.
I froze.
My uncle smiled, and thanked me for a job well done and the conversation turned to other things. I was again relieved.
The rest of that evening passed with no more mention of the garage until bedtime.
Stripping naked, I crawled under the covers and went to bed happy about it. But the thought of my aunt catching me wouldn't leave me alone.
My cock hardened under the blankets and I stroked myself to the mental image of my Tia Lucy.
In my fantasy, I was standing in the garage, stark naked, as she walked slowly towards me. She was fully clothed, and her huge tits swayed under her sweater. My cock pounded and throbbed for her...looking down at it she smiled. The idea of being totally naked and hard in front of her was so exciting, as I beat myself beneath the sheets.
"Hi sobrino," my fantasy aunt whispered, smiling into my eyes.
I came hard, under the covers, soaking the sheets with sticky warmth. When my orgasm subsided, I fell asleep to the fading image of my aunt watching me jerk off naked.
