It was nearly 11:00 on a Tuesday morning in the month of August of 1980 when I awoke.
I had a severe hangover, having drank far too much beer the day before. Our parents had gone away for a week of travel to Maine and Nova Scotia, and my sister and I had been left home alone.
I was 19 and she was 18, so naturally the first idea that popped into our heads after our parents drove off in the Buick was to call our friends and have a party.
The drinking started just after noon the previous day, and continued long into the night. It was probably after three in the morning when the last of our "guests" left. I told my sister we could clean up the horrible mess the next day, and she drunkenly agreed.
As I listened to the traffic drive by on the street outside, I blinked my eyes a couple of times and re-entered the world of consciousness. It was hot, hotter than a normal August day in New Jersey should be. I had gone to sleep, well, passed out actually, without having turned on the fan in my bedroom and now I was a ball of sweat.
I got out of bed with the intention of turning on the fan on my dresser and then climb back into bed, but once I was on my feet my bladder told me that I should urinate. Wearing only my boxer shorts, I walked down the 2nd floor hallway to the bathroom. Once I finished pissing, I looked down at my cock and balls and noticed how full my ball sack was. My cock began to harden on it's own. For whatever reason, I had found that the morning after a night of drinking my cock was harder than normal and I had a full load of cum sloshing about in my balls, waiting for release.
If I had simply masturbated right then and there, my future would have been a lot different than it turned out. But I didn't. I washed my hands and brushed my teeth and left the bathroom, content on being up for the day.
I passed my sister's bedroom and noticed she hadn't closed her door all the way. For reasons I cannot explain, I gave the door a push and it wide open. She lay on top of the covers, clad only in a pair of red panties. She was laying on her stomach with her legs spread lewdly apart, snoring loudly.
I knelt down at the end of her bed and watched her lay there, her ass rising and sinking with each breath. She was out like a light, so I, probably still a little drunk from the evening before, walked over and began to gently rub her legs with my hands. Her skin was so soft and warm. My breath began to get labored, my cock stiffened without a touch and rose against the confines of my boxers.
