My mom has always had the belief that what her husband doesn't know can't hurt him. He's her third husband, he came around at the time I was twelve and since I had spent most of my childhood with my real father and a few years with my mother's second husband he'd never really seemed like a father to me, but I still saw him as my mother's husband and an authority figure.
By the time I was eighteen, which is when this story takes place, we'd pretty much just become friends. He and I have always gotten along rather well. We like a lot of the same things, cooking shows, history channel, being outdoors, that kinda thing. I used to bake a lot and he liked my cookies so much he never wanted my mom to bake (something she was rather jealous of). Little did I know at the time that he liked some other things of mine better than hers as well but I am getting ahead of myself.
As I was saying, my mother tends to think that if she wants to do something that my stepdad doesn't like she can easily go out and do it and then lie to him. She always says "What he doesn't know wont hurt him." So how could she really be surprised when he'd eventually start thinking the same way?
Unlike my mother I am very well endowed in the chest region and when I hit my late teens I lost my baby fat and developed a lovely 36, 24, 36 figure. My tits were very large, a D cup at the time, and men always loved to look at them. Sometimes I would wear these little see through camisoles to the store and enjoy watching women get mad at their husbands for staring. I was just learning the power I had over men and had no idea what to really do with it.
Now, my stepfather had a nighttime ritual of brushing out mine and my mom's hair and then rubbing our backs. As can be imagined having heavy breasts often caused me a bit of back pain and I found this rather helpful. Usually he would rub my mother first and then she would go to bed while he was rubbing my back. We would watch a cooking show or something and eventually he'd get tired and go to bed.
Of course usually that was followed by my mother squealing ten minutes later but I never seemed to put the two together at the time.
What he didn't know is that usually afterwords I would pull his navy picture off the wall and take it to my room with me. There I would set it up on the bed, strip for him, and then lie on the bed with his picture between my legs. I would lie back and spread my virgin pussy and gently rub it, teasing myself and imagining him watching me. Maybe a little silly, but I was just 18 and still a virgin.
One night my mother had to work late so my stepfather promised a little extra time to work on my back. As I sat there watching the show and delighting in the feel of his hands on my back he asked if I could take my bra off as that would make it easier for him to get to my back.
"Sure, no problem!" I reached back and unsnapped my bra and proceeded to pull it out of my shirt sleeve. Immediately I started feeling naughty. I wasn't often without a bra around him and the feeling of the shirt on my nipples was getting me excited. I had a man's hands under my shirt, albeit from the back, and I wasn't wearing a bra.
The show continued and I watched it, but I noticed his hands every so often brushing the skin under my arms and just barely brushing the sides of my tits. I battled quickly with myself. This was my mother's husband, however he was also the only male in my life currently and I'd never felt this pleasure before. Besides, how many times did she do things and lie to him about it afterwards? So I lifted my arms away from my body just enough to allow him access.
Slowly he worked his hands around to the front and began brushing his fingers along the bottom slope of my tits. I could feel myself getting wet. I tingled with every brush of his fingers.
"Are you sure you're okay with this?" He asked me. Of course I was!
"Yes!" I replied somewhat breathlessly. He pulled me back against his chest and began fondling my tits aggressively. He cupped them, squeezed them, and began tweaking my nipples. He never did it to the point of hurting me and I've never known another man to touch them so perfectly.
As I scooted closer to him, being seated between his legs, I could feel the bulge in his pants push against the small of my back. I had never seen a cock before and I wanted to so badly but before I could ask I heard a car pull into the driveway. Mom was home!
I quickly jumped off his lap and grabbed my bra, shoving it under the chair I usually sat in. I sat in the chair as my stepfather composed himself. I heard the car door shut and knew she was walking up the driveway.
"Can I see them?" He asked so quietly I had to ask him to repeat himself. "Can I see them?"
Without a thought, seeing the back of my mother's head out the window behind him I quickly raised my shirt and flashed my large D cups at him. The look on his face was priceless. I quickly pulled my shirt down just as I heard the key go in the lock on the front door.
Mom came in. "Hi, guys." I merely smiled. She kissed her husband hello, made some comment about the show we were watching, and then went to her room to change.
My stepfather looked at me and smiled. I smiled back. With a glance toward her closed bedroom door I quickly lifted my top again and rested the cloth above my tits. The possibility of getting caught was exciting me and my nipples were hard but exposing myself was always a turn on for me and I'd never had a proper audience before.
I sat there with my top up, my eyes locked on my stepfather who simply stared. I tweaked my nipples a bit and ran my fingers lightly over the soft skin when I heard the doorknob to their bedroom squeak. I quickly lowered my shirt and went back to staring at the TV. Mom was in her robe and was off to brush her teeth before bed.
As soon as she was in the bathroom my stepfather turned to me and said, "She can never know." Well, duh. What kind of idiot did he take me for? I blushed a little, though.
"Do you like them?" I asked, fondling the hem of my shirt but not lifting it.
"You have no idea," he said, trying to adjust his cock in his pants. "Now I just need to calm this down a little before your Mom gets suspicious." I watched him make his adjustment and then my eyes met his and he was grinning. I blushed and looked away.
"Hey," he said, a little quietly, "I forgot... it's supposed to be 'you show me yours I show you mine', right?"
I glanced up at him and he was grinning. I probably went beet red. I knew what he meant and I was so curious. He glanced over to the bathroom door again, then to my surprise he undid his jeans and fished his cock out of them.
I was transfixed. He'd always joked about having a small cock but it looked big enough to my inexperienced eyes. It also looked weird but I kinda liked it at the same time. He quickly tucked it away again, much to my dismay, but it was for the best as my mother came out of the bathroom soon after.
To this day she is the only person I've ever known who can go to sleep right after getting home from work. In her defense, however, she'd just worked a shift that kept her up way past her normal bed time. She mentioned this to my stepfather, pointing out that it was past his bedtime as well and he assured her he'd be joining her soon. She said goodnight, told me to turn the TV down so it wouldn't keep her awake, and went to bed.
After a minute or two my stepfather got off the couch and came over to my chair. He whispered, "Hey, I gotta go fuck your Mom now, she's expecting it. I don't know why she always tells you to turn the TV down first, like you want to hear that. But, I'll be thinking about you this time." and to my surprise he took my hand, looked me in the eye, and kissed it like something out of a movie or something. Then he followed my Mom into the bedroom.
That night while I fingered myself to his navy photo all I could think about was the excitement of his looking at me and that lovely cock he'd showed me.
I had really enjoyed myself and I knew I wanted more. As I lay there I thought about how often I was actually alone with him. It was mid summer and I was out of school. Usually they both worked weekdays but not long ago mom had been put on a new schedule. Now she worked days three nights a week and nights on Tuesdays and Thursdays. Also, in the morning she usually left about twenty minutes before he did.
Today was Tuesday, so that meant tomorrow I would have twenty minutes before he left for work and then Thursday we'd have all evening. My mind started spinning with thoughts of ways to get that wonderful excited feeling again. While I tried to sleep an idea occurred to me.
I had to set my alarm in order to get up on time, what self-respecting teenager is up before noon in the summer? So I set my alarm and fell asleep dreaming up a plan.
At 7:45 the alarm went off and I was groggy but when I remembered what I had set it for I snapped right awake.
I could hear them getting ready, talking to each other, making plans for the day. I slipped out of bed and began searching through my drawers for something to wear. I settled on a pair of dark blue boyshort panties and a matching camisole. Now, for those who don't know, camisoles, at least the ones I buy, tend to be a very tight fitting stretchy material and this one, once stretched over my chest was practically see through. It was only the darkness of the blue that kept anything hidden.
I would normally never dress like this in front of him. I was very shy, and while very sexually minded I never wanted anyone to know that side of me, until now. Everything I'd learned about sex I'd learned from the internet. I learned to shave my pussy, wear sexy lingerie, buy dildos, and even read a manual about how to properly suck a cock. I guess I was just waiting for the right guy to try them out on. I never would have guessed it would have been my stepfather!
I checked myself out in the mirror, running my hands over my flat tummy and the swell of my hips and breasts giving me a nice hourglass figure. Depending on the way I stood the light would either shine through my top, showing off my breasts and my dark nipples, or merely a shadow of them covered in blue.
It was perfect. I sat on my bed, trying to ignore the tingling in my pussy at the idea of a man seeing my like this for the first time, when I heard my mom say goodbye to him and shut the door. I listened harder. The car started. A few minutes later it had pulled away. I hoped she didn't forget anything.
Slowly I opened the bedroom door. He was in the bathroom just one door down and I waited until just the moment when he opened the door, took a deep breath and dove in, or rather stepped from my bedroom.
