After I finished high school my family moved to a city near my college and dad's new workplace. Our stuff hadn't arrived yet and we were sleeping on a mattress on the floor. Though we had two bedrooms we had to use only one.
I had just turned 18 and started college. My dad is 48 and mom 42. Dad was dark, fat but strong. Mom was fair, smooth skin, curvy but not too much. She had good waist to hip ratio with modest boobs. Dad had a belly, big forearms and strong legs.
In one of the first few nights, dad entered bare chested in pyjamas late at night in the dark bedroom where mom was sleeping and me on other end of mattress, trying to sleep.
I was lying on my back but faced turned slightly towards their side. There was little street light or moonlight coming through the window curtains and it was enough to see their bodies.
Dad put his hands inside mom's nightwear neck and groped both boobs for few seconds. Then maybe put his hand down inside the blanket. Next thing I saw mom whining a bit but slowly get up on her knees with her ass up, back arched, supported on elbows, head down on the pillow.
Dad stood up behind her on his knees without the pajamas. In the dark I couldn't see his exact privates but I could make out he put two fingers on each side of mom's panties and swiftly pulled it down midway between mom's knees and ass. Then he started pushing his thing behind mom. Slow swinging motion at first but his speed was increasing gradually. Grabbing mom by the hips, he kept banging for well over an hour. Midway he stopped his thrusting for few seconds and pulled back mom's hips forcefully towards him. There was a wet farting noise of the remaining air coming out of my mom's seasoned pussy. Then continuing to thrust deeper and faster, making lot of weird noises.
