When I left home after college, my parents sold the house, and had moved into a small condominium.
I knew I had crowded them by moving back home, but it was only a temporary arrangement, and they enjoyed the cramp crowded company of their daughter more than they thought about the tight temporary living conditions.
The second bedroom was being used as office space, so I typically crashed on their couch. Often though, like tonight, we were in the living room watching TV, and being how the couch was occupied by each of them, I had to comfy-up with some pillows on the floor.
They enjoy televised sports, and while I enjoy attending futball (soccer) games, its excitement of the game and crowd is lost on television. I got up to pee and upon returning, I hesitated, placed a hand on the door knob of their bedroom, pried it open a bit, took a small step into it, then peaked out telling them "I am calling it a night", then completed my entry into their bedroom. I was indeed tired ... also ... I made it a habit of offering them alone-time which they had grown accustomed to ... and early-to-bed had always proved to be an easy way to accomplish it.
I closed the door to their bedroom turning on a small lamp in order to downturn the bed covers to complete my simple undressing routine of dropping out of my robe and losing my pajama pants. I typically sleep in the nude, but when I sleep in their bed, I keep attired in my night shirt and panty. Besides, I had just peed, and since I am habitually careless when tired, I had not been real careful at my douche ... I knew it best to keep them donned. So, I was drip-drying away assuming my padded crouch would suffice in not marring the sheets.
As, it turned out, the weekly laundering of their bed covers had not been completed, and even through the dim light, one could make out the beautiful earmarks of their passion-stained-sheets. My eyes darted to a rather large spot ... looked permanent, possibly produced from a past pool of both of them, and then splattered about were smaller more recent seminal emissions on dad's typical side of the bed that were clearly male in appearance ... daddy's as he probably jerked himself or from a hand-job from mama during the week.
I extinguished the lamp.
Shimmying into the bed, I laid on my back waiting for the Sandman who apparently took the night off probably due to the noise of the television as well as the sudden roars of the crowd emanating at unpredictable times. Still awake for at least 15 minutes, the familiar teasing tempting thoughts of "Should I?" entered my brain. My reply ... I hooked the elastic on both sides of my panty with my thumbs, raised my butt a bit, rolled down the panty, and led it down to my ankle so I could retrieve them when I had finished myself.
I moved my legs ... my knees now pointing to the ceiling as I am prone to do when I masturbate when lying on my back. It would not take long as I spread my labia with my left hand, finding some girly-oil readily available with my right index finger, and waved it towards my clit. It is a comparably small clit, nothing to "write home about" ... one might need a map to find it ... but I was well aware of its hiding place and my favorite fantasies soon began racing through my head as I circled the wagon. Typically, I would put a towel beneath me; however, I was not worried about soiling the sheets as I figured any emissions, once dried, would simply blend in with those already present.
My girly-goo was performing admirably and I knew an orgasm was imminent. As I was nearing the completion of my secretive self-play, I heard dad's footsteps nearing the door. Apparently, the game had been decided and he was coming to bed as well. Mom, apparently, was a bit more hardcore and was watching the game to its conclusion.
