At fifty I'd felt incredibly lucky to meet a beautiful forty year old woman such as my new wife, Catherine. She was smart and sexy and when she agreed to marry me after just a few months I felt like the luckiest man alive. Our sex life was off the charts and I'd never been happier. The only snag was her eighteen year old daughter, Marie.
Marie was every bit as beautiful as her mother and smart as well but she had a devilish streak and loved to push her mother's buttons. They argued a lot over grades and curfews and such and I just tried to stay out of it.
Marie was a terrible flirt too and I often wondered if she flirted with me just because she could or just to try and piss her mother off. I suspected it was the first reason since her worst offenses usually took place when her mother wasn't home or at least not in the room.
Catherine was tall and statuesque with large C cup breasts, pale skin, and light reddish brown hair. Marie had inherited her father's more swedish coloring and she was the epitome of ever male's beach blonde, California girl. She was tall and thin with a long torso, high and round, firm breasts that were even slightly larger than her mother's C cups. Her ass was a perfect full heart shape and her skin was smooth and blemish free. Her hair was long and silky smooth, white blonde and a smattering of light freckles across the bridge of her nose gave her just a hint of that girl next store appeal that the boys all loved.
Marie was not often without a boyfriend but none of them lasted. She was somewhat of an exhibitionist and loved to parade around the house in the skimpiest of costumes. I couldn't help but notice but I kept my opinions to myself, only chiding her jokingly if things got too out of hand. Lately, she'd taken things to a new level. She'd walked in on me in the shower last week and then paused there, staring and smiling. Casually, she'd begun caressing her bare stomach beneath the tube top she wore and slowly licked her lips. I grew hard in an instant and did my best to cover myself with the washcloth.
"Privacy, please, Marie," I prompted.
She didn't budge at first, continuing to rub tiny circles across her flat, tan stomach.
Finally she tore her gaze from my barely covered package and made eye contact.
"If you insist," she drawled with a pouty smile.
"If you change your mind, you know where my room is."
I wanted to chalk this up to simple teen-aged teasing but I have to admit it got part of me wondering... what if?
I'd be crazy to act on this, I told myself. I already had Catherine. I loved her and our sex life was great. If only Marie weren't so amazingly beautiful and sexy in her own right.
Lately, Catherine had been having trouble sleeping and she'd taken to using a prescription sleeping pill to help her get to sleep. The medication worked like a charm and she now slept deeply for at least six hours. I'd tried to wake her to take a phone call a few nights ago and was unable to even wake her long enough to take it.
We joked about it at dinner and Marie got the strangest look on her face. I caught her eye and she gave me the same pouty little smile she'd flashed at me in the shower the week before and winked subtly before excusing herself to do some homework.
Catherine and I made love quickly that night, just after she'd taken her sleeping pill. It was satisfying but not one of our more adventurous nights and I was still slightly horny and left thinking about Marie after Catherine was breathing deeply beside me.
I tossed and turned for another twenty minutes or so and then finally felt myself drifting off to sleep.
What seemed like only moments later, but a quick glance at the clock confirmed was an hour past, I felt my cock being softly stroked beneath the thin sheet that covered my lower extremities.
Amazing, I thought, Catherine must not have been satisfied either.
In the split second it took for me to think this I quickly became aware of two things. My wife's deep breathing was unchanged beside me to my right and to my left, softly backlit with the light from the hallway streaming through our bedroom door, was my step-daughters face, inches from mine, where she kneeled beside the king-sized bed.
"Marie," I hissed, reaching down to pull her hand away.
She tightened her grip though and I only found myself squeezing her hand tighter around my now awake again, cock.
"Shhh, Daddy. You wouldn't want to wake Mommy, would you?" Marie teased. She never called me Daddy in our day to day life but apparently this fantasy was all part of the turn on for her.
"Go back to bed, Marie, you've got to stop this."
My breath caught in my throat as she loosened her grip slightly on my now engorged cock and began stroking it, ever so softly.
"I love your mother, Marie. This can't happen."
"I love my mother too, Daddy. But, you make me so horny and she never has to know. Did you fuck her tonight?"
When I didn't answer Marie flicked the sheet off of me where it landed across Catherine's bare hip and leaned over me where she ran the flat of her tongue up the length of my rock hard shaft.
"Mmmmm... you did fuck her tonight," she murmured and sounded satisfied.
