Hi, my name is Keri. I'm eighteen and I live with my mother and her new husband, Derick. My mother divorced my father three years ago and he lives across the country in New York where, since I live in California, Pomona area, I don't see him very much. I guess now that I'm eighteen I could move back east and stay with him but he's always busy working and I probably wouldn't see him much. I like California anyway, the weather is so much nicer all year around. We have a house that looks over the valley and I like to get on the roof at night and look at the lights and enjoy the cooler air. My mom doesn't know I do that, but it's pretty easy from my bedroom window.
She met Derick about a year ago and they got married a few weeks back and now I have a new stepdad. He's pretty cool, handsome and has kept himself in good shape for his age. Mom seems quite taken with him and is probably the happiest she's been in ten years. After their honeymoon we all moved in together and I started to have to worry about what I wore around the house or to remember to lock my door and the bathroom. It was kind of odd to have Derick in the house now and having to change the way I lived slightly. I obviously knew he and Mom were having lots of sex. I could sometimes hear them going at it but that's what headphones were invented for.
I was doing pretty good to not get in their way or interfere or be a distraction to them until last Thursday night when I was on the roof at about 11PM. I started hearing noises from below and realized Mom and Derick were going at it again. I turned my head and looked behind me to where I heard the noise and spied the bubble skylight that opened into my mother's room. I don't know why I did it but I snuck on my hands and knees for a look. Every so carefully I moved my head and looked down through the clear Plexiglas. My eyes widened big time with what I saw. Mom was on her hands and knees with Derick taking her from behind but it was the size of his cock that shocked me so much. It was huge, the biggest cock I had ever seen. His body moved at least eight or nine inches away from my mother with each thrust and I could tell he was leaving a good two or three inches still in her. I couldn't turn away or even blink as I watched him pound his huge cock into my mother's body over and over as she moaned and clenched the bedsheets in her fists. She finally had to put her face into her pillow to keep from being too loud as I saw her start to shake and tremble from what looked like a massive orgasm.
I could feel myself getting wet and my nipples pressing out in my braless night shirt I had on. What I was watching was so wrong but had me all sorts of turned on. Derick's huge cock was coated in Mom's juices and he pounded her all the way through her orgasm until she couldn't take anymore and fell limp onto the bed. That's when I finally got to see the entirety of his cock. When Mom fell forward he flipped out of her. It was spectacular and my mouth fell open. His head was purple and ready to burst, the length and girth was un-paralleled to anything I had even imagined before. Large veins were clearly defined along his shaft, pressing out among the hardened flesh. It looked longer and bigger around than my forearm, granted I'm a tiny petite little thing but still it was fucking huge. It only got better when he took hold of it in his large hand and stroked himself off onto my mother's trembling back.
Huge bursts of thick white semen exploded from his purple head and splashed onto Mom's back. It had to be seven or eight giant ropes before he began to dribble down onto her butt. I had never seen anything like it before and suddenly realized I was grinding on my clit with my right hand through my panties and night shirt. My mouth had fallen open, my breathing and heartrate had increased, I had to force myself to turn away and calm down.
Climbing back into my room, I pulled off my sweaty night shirt and stripped off my wet underwear, before getting into bed. I was so horny I couldn't stand it. That cock of Derick's was so amazing I couldn't stop thinking about it and imagined it inside me as I masturbated in my bed. I teased my clit and fingered myself with as many fingers as I could fit, pretending it was his cock. It was so wrong so dirty but I couldn't stop and brought myself to a massive climax as I pretended he was cumming all over me with that huge cock in his hand. I fell asleep soon after and slept naked and wet but deep all night.

The next morning at breakfast I'm sure I was acting weird. I was quiet and reserved and tried not to make eye contact with either of them. I was a little ashamed about watching them having sex but couldn't blame myself because of the spectacle it had been.
"You're awfully quiet this morning," my mother said.
"Must be tired," I lied.
"Didn't sleep well?" Derick asked.
"Guess not," another lie.
Mom was just in her robe and Derick had on some sweat pants and a tee shirt. I stole a glance at his crotch and was surprised I hadn't noticed it before. You could tell he had something big under there. I knew first hand now that's for sure.
"Well, you can take a nap today we don't have much planned," Mom said.
I smiled politely and looked at my mother's body in her robe compared to mine. She was taller and had much bigger hips and breasts. I must have gotten my tiny frame from my Dad's side or something. I couldn't stop thinking she was built more ideally for a cock like Derick's. It got me thinking and wondering if he'd even fit inside me. I wasn't a virgin, not even close. I've had several boyfriends but was in-between one at the moment. My last decided to break things off since he was going to college in a different State. I'm sure he wanted to screw other girls while he was there and I couldn't blame him for that.
I had never seen an older man's cock and I wondered if they just keep growing and that was why Derick's was so big because none of my boyfriends had anything near the size Derick had. Or maybe he was just endowed more than others. Whatever it was it was enormous and I couldn't for the life of me stop thinking about it. I might have stared a little too long at his crotch during breakfast thinking about it. I wasn't quite sure if he noticed or not. I excused myself and went back to my room after eating.
About a half hour later, Mom knocked on my door and said she was running some errands and would be back in a couple of hours. I assumed Derick was going with her until I heard the shower turn on in their master bathroom. I was bored and my mind went to places it really shouldn't since he was my new stepdad but I thought about him in the shower soaping up his giant penis and making it get hard and long with the soap. I worked myself up enough to do something stupid. I got off my bed and went out into the hall. Mom's door was open slightly leading into their room. The bathroom is further back with its own separate door. I knew Mom wouldn't be back for a while and decided to sneak in because the shower was still running. I didn't know what I might see if anything but my arousal was apparently in control of my actions. Inside the room I looked up at the skylight above the bed and smiled as I walked toward the bathroom door.
It was slightly ajar, giving me a tiny glimpse inside. The shower glass was mostly fogged up by then but I could still see the blurry outline of Derick's long flaccid cock wobbling back and forth between his legs as he washed himself. It was another deer-in-the-headlights moment for me and I couldn't turn away as I watched him shower. I wanted a better look because the crack in the door wasn't big at all. I don't know why I did it but I parted the gap a little bit more with my fingers and continued to watch. Suddenly, Derick looked out of the fogged glass at the door and must have seen me because he said.
"Babe? That you? You already back?"
I didn't answer, instead I turned and practically ran back in my room. I cursed myself for being really unwise. He had to know someone was watching him and he wasn't stupid. He'd know it was me. I was busted big time. I could just see him telling my mother and then her confronting me. My life was over. I dreaded the next hours, locked in my room. The shower had turned off and I didn't hear from Derick assuming he was waiting for my mother to come home. When she did I expected the knock on my door and the angry confrontation that would come with it but it never happened. Derick had apparently never told my mother or maybe he thought he imagined it or something. I tried to act normal around her and him and thought I was in the clear for a few days.
About a week passed and I was out on the roof enjoying the evening once again when I heard them making love. Since nothing had happened since the bathroom I thought I was in the clear so decided to take a peek again. This time Derick was on his back and Mom was riding his big cock, holding her breasts in her hands and riding him like a pro. I couldn't see what I wanted to see and was hoping they'd change positions so I could get a glimpse of his massive dick. Problem was, he was on his back and I must have moved too far into view because his eyes suddenly locked with mine and he smiled as my mother was riding him. For that split second I didn't move and I knew he knew everything. He knew I had spied on him in the shower and he knew I was spying on them now and he liked it and smiled.
I quickly pulled my head away and quietly returned to my room, my head a whirlwind of thoughts. He was keeping my voyeurism to himself. What could that mean? He didn't want to tell my Mother because he knew I'd get in trouble and apparently he didn't mind me watching or he would have told her. That was kind of creepy but then again I was the creepy one. I wondered if he'd ever confront me or just let it go and call it curiosity of a teenager. I got my answer a few days later.
