When I was a kid, I spent a lot of time around my aunt. She was a very pretty and shapely young woman at that time...rather busty. I remember her bending over in front of me at the refrigerator or when she was doing laundry. I'd see right down her shirt. Around the age of 15, I started fantasizing about her all of the time. When I was 16, I spent part of the summer with her and my uncle. She didn't work at that time, so we spent every day together.
It seemed to me at that time, that she was bending over in front of me more often...or perhaps I was just noticing it more. She'd catch me staring at her boobs and laugh. After being caught, I'd stammer and apology, but she'd smile, ruffle my hair and tell me it was normal. Once, I was in the garage. I'd found my uncle's Penthouse magazines. My aunt was in the house. Being 16, I couldn't help myself. I unzipped and started jerking off. Suddenly, the door opened. I heard my aunt's voice behind me. Well, I couldn't turn around all of the way, so I twisted at the waist to turn and see what she wanted. My cock was in my hand in front of me.
My aunt was wearing a bikini top and shorts. She gave me a strange look and asked if everything was ok. Totally embarrassed, I stammered that it was. She stayed there a moment looking at me, then closed the door. I hurriedly finished and zipped up. A few days later, I was in the shower in my aunt and uncle's room because the shower in the hall bathroom wasn't working. My uncle was at work and my aunt was off somewhere. I was alone.
Long story short, I was whacking off, imagining my aunt naked. I had the shower door open, as well as the bathroom door...knowing I was alone. I was going at it...about to cum. When I opened my eyes, my heart stopped in my chest. My aunt stood there, in just her underwear, watching me. Her hand was busy between her legs. Being 16, I quickly got over my shock and came hard...really hard all over the place.
My aunt orgasmed as well, then ran out.
Well, after that, we never talked about it. But she would give me this look and smile every so often. When I tried to bring it up, she would just shake her head and say "no."
