My wonderful, sexy wife and I have been married for over a decade now, and have had an amazing sex life throughout our marriage.
Erin has a lovely daughter named Katie. Now, as much as I'd like to say that Katie and I have always gotten along, that would be a lie. When she was young, we had an amazing relationship, but that went sideways unfortunately.
Katie's biological father "lurked in the wings" for lack of a better term. Katie and I would get along fantastically, then dear old Dad would show up and poison her mind with lies, slowly driving a wedge between us. As a result of his meddling, our relationship deteriorated over the years, eventually ending up in her moving out at 15, and us hardly ever speaking.
Fast forward to now. Katie has grown into an interesting 18 year old. She's opted to be a fairly dark individual, dressing in the "goth" or "emo" style, and avoiding sunlight. I've jokingly called her our little vampire, as she's extremely pale, inheriting her mother's fair ginger skin. She's also very petite like her mother, although much shorter, having stopped growing when she hit 5'0" tall.
Katie wanted to continue her education, and with the cost of living these days, she realized that working and going to school simply wasn't feasible. She spoke with my wife about possibly moving home with us to go to school and we agreed that this was viable, and her best solution.
When Katie moved back in, things were pretty awkward between us. We didn't really have the closeness of a step-father and daughter, but also didn't have any animosity, just a strangely awkward relationship. We were polite with one another, making small talk and eating together, but not really hanging out together unless my wife was present. As time progressed, we became more comfortable, but still not as close as we once had been.
Katie kept to herself for the most part, but hung out with us during and after dinner each night. We had a bit of a routine where we'd eat, then watch a movie or show in the evening while having a drink or two, before eventually calling it a night. Katie enjoyed her hard liquor, usually having a good buzz by the time she'd go to bed.
I've always been attracted to petite women, and as much as I hated to admit it, I did notice that Katie had developed nicely. She had a tiny flat tummy, perky bum and a tiny chest with perky little nipples which could be clearly seen through her tight tops. When we hung out at night, she'd wear pyjama pants and a tight shirt. She rarely wore a bra in the evening and I couldn't help but notice her breasts jiggling and nipples poking at the straining material.
At one point, after Katie had been living with us for a couple of months, my wife had to leave town for a big company seminar for a week, leaving Katie and I alone together. The first night together, Katie ate with me, making small talk, then stayed and watched a movie with me. We had a few drinks and Katie got a bit of a slur to her speech, and was far chattier than she had been up to that point. I assumed the alcohol was lowering her inhibitions and making it easier for her to be friendlier. The movie was nothing special, and eventually Katie drifted off to sleep on the sofa. I pulled a blanket off the back of the sofa and draped it over her to keep her warm as I continued to watch the movie.
After 15 minutes or so of Katie falling asleep, I heard a faint moan. I was sure at first that what I'd heard was the TV, but then I heard it again and realized the noise was coming from Katie. I looked at her, noticing her beautiful, pale freckled skin and admiring her beauty. While I watched her, I heard her moan again, then noticed the blanket move slightly.
I whispered, "Are you awake?", but got no reply other than another quiet moan and more movement.
Dying to know what was going on, I gently pulled the blanket back to the side and noticed that one of Katie's hands was between her legs, moving gently. She was having a dirty dream and was touching herself. My cock instantly hardened to the point of almost being painful. I'd never looked at Katie in a sexual way until that moment. Now I stared, noticing her black dyed hair in harsh contrast to her perfect, pale complexion. Every feature on her was petite, and nearly perfect. For a moment, I wondered how I had never really noticed her sexual beauty.
I tried desperately to ignore what was happening beside me, and to focus on the movie, but it was futile. Katie's hand moved more, she moaned more, then suddenly trembled, panting like a dog in heat. Katie's cheeks were suddenly full of rosy colour. My cock strained and ached and for a moment, I was concerned that I might actually ejaculate as I felt it begin to twitch. My concern and excitement ended quickly when Katie started to stir, woken by her own climax.
I dropped the blanket back over her and pretended not to notice anything, turning my attention back to the TV just in time. Katie removed her hand from between her legs, pulling both arms out of the blanket, then cleared her throat, "I must have dozed off, sorry." She then noticed the blanket, "Thanks for covering me."
I told her that it was fine and assured her that she had no reason to apologize for falling asleep. A moment later, she excused herself and went off to bed.
That night, despite my best efforts to remind myself that she was my step-daughter, I kept fantasizing about Katie and masturbated twice before I could settle myself enough to go to sleep.
The next day was like any other, except that I couldn't stop from becoming aroused repeatedly and noticing just how tight Katie's black stretch jeans were, and how her tiny waist transitioned to her large chest.
Katie went out that afternoon and I masturbated again, trying to relive my sexual frustration. My wife Erin rang and we had a long chat about her conference. I couldn't believe that she'd only been gone for 1 day of the 7 she was to be away for.
I'd barely hung up the phone before Katie rang, "Are we watching a movie again tonight?" she asked.
"Yes, if we can find something worth watching" I replied. My heart immediately pounded in my chest as I wondered if she would repeat her performance from the night before.
"Good. I noticed we're out of whiskey. Want me to grab some while I'm out?" she asked.
"Yes please!" I replied, perhaps too eagerly as my mind flooded with images of her dirty dream. I was immediately turned on at the possibility of it all happening again, feeling my cock harden again. I hadn't been this easily aroused since my teen years. I don't know why, but I soon found myself standing in Katie's room, day dreaming. I noticed something on her floor next to the bed. I picked up the fabric and discovered that it was a pair of black, Lycra panties. Without another thought, I brought them to my nose, inhaling her musky scent deeply. The panties didn't smell of sweat, but of womanly juices and I was sure they were likely the pair she'd worn the night before. I started to open my jeans, and was about to wrap her dirty panties around my hard cock to jerk with the soiled garment when the sound of the front door closing snapped me out of my trance.
"I'm home!" Katie hollered.
I rushed to the kitchen to begin dinner. Katie promptly grabbed us each a glass, clinking an ice cube into each, then poured us each a hefty drink. We drank through, and after dinner, having multiple drinks each. It wasn't long before her tiny body's resistance to the alcohol was overcome and she started to slur again. "I'm going to get changed into something comfy so we can start the movie." she announced, then left for her room.
When Katie returned, I think my jaw visibly dropped. She'd changed into a long t-shirt which was only about 6 inches longer than the bottoms of her panties. It was the first time I'd seen her bare legs, and they were perfect. Pale, slender and smooth, with light freckles. She sat at the opposite end of the sofa as usual, but grabbed the blanket and draped it over her legs, for which I was grateful as I didn't think I could resist staring at her bare legs if they were exposed, nor resist trying to look up under her shirt.
We watched the movie and drank more. I made sure to pour large drinks for Katie and soon she was slurring, then she dozed off again. I stared at her gorgeous face again, taking in her beauty as my cock hardened once more in hopes she'd have another naughty dream.
