It was a sunny Sunday afternoon. The big family meal was over and everyone had retired to their rooms to rest. This was an old tradition in our family. The week's stresses and duties were all forgotten during this three or four hour period and we would just slumber the afternoon away and recharge ourselves for the week ahead.
Invariably, the bed springs in our parent's room could be heard squeaking as they slowly bounced up and down as my father was giving it to my mother again this afternoon. She always lay back on the bed towards the centre and stretched out her legs as she spread them wide, sort of pushing my father over a bit, and then he would roll over on top of her, fumble a bit and then start thrusting. My mother's legs would rise up of course, and sometimes she locked her ankles around his waste. They always did it in the missionary position, sometimes with a pillow under her ass. You could hear their bodies slapping together as he pistoned his cock into her, and you could see his balls slapping her ass as they bounced against her when he slammed into her.
This rhythm seemed to go on for a long time until my mother would start to gasp and her breathing would get shorter and shorter. She would sometimes make these funny squeaking sounds as she tried to muffle her moans so we wouldn't here them fucking. This was sort of funny to us because all of us grew up hearing them in the tiny bungalow that we lived in. Nudity and nakedness was common in the house but all of their fucking was done behind closed doors in their bedroom. Sometime during the summertime when the temperature was hot, they would leave their door ajar, or it would swing open and when they were in the throws of passion and oblivious to their surroundings, we could watch them fuck and sometimes even masturbate while watching.
My father had this average size, uncut dick, and usually he would fuck my mother until she came and then he would shoot his load. This used to take 10 to 15 minutes and happened four or five times a week. After fucking, he sometimes would walk into the bathroom while he held his cock with one hand and he would hold his cock and balls over the edge of the sink and wash them with soapy warm water.
My mother was very curvy, with a few extra pounds. She had beautiful thick fur on her pussy, and as I was able to observe one time when she was bent over, knelling down, had the chubbiest pussy lips that needed to have a cock shoved up between them. Usually after fucking, she just rolled over towards my dad, and let her heavy mommy breasts with her big brown nipples lie like soft pillows where my dad would place his head when he returned to bed.
All of this bedroom activity excited my sister and me on a regular basis. When we were both seniors at high school we used to compare notes, when we were walking to school and talk about how hot it made us feel. We described in detail how we stroked ourselves and made ourselves cum while our parents fucked across the hall. I must say that we got pretty good at it and we could time our orgasms so that they erupted at the same time mother was gasping and wheezing and dad would groan.
About this time we both began sleeping in the nude, and when we would hear the talking stop across the hall, we would know that the fondling had probably begun. That would be our clue to turn off our lights and open our doors quietly and then lie down with the covers pulled down and then we could begin stroking ourselves and keep time to the bed springs across the hall. When my sister and I got a little bolder, we would prearrange during our walk home, who would watch the other from the darkened doorway. I loved to watch my sister get off. She would raise her hips as her legs stiffened, and she would pull a pillow onto her face to muffle any sounds she uttered. Watching her and hearing our parents at the same time made it impossible to hold back. Cum would shoot out of my cock so hard, and as the precum dripped out and lubed my shaft, I would struggle to catch the creamy white cum so that it wouldn't get all over.
My sister and I obviously progressed to where we lost our cherry's to each other. Many times we would fuck with wild abandonment when our parents were away and had left us alone.
