Katie is my step daughter in her final year of high school. Her mother & I got together when she was 8 & 10 years later, she has grown up in to hot young woman. I mean long blond hair, slender, curvaceous body & E size boobs that defy gravity.
I never really took any notice of her in that way until a few months back. I noticed doing the washing, some new bras & panties, that were pretty sexy & grown up looking.
I asked my wife if they were hers & I just hadn't noticed & she said they were Katie's. She decided to buy herself some more grown up clothes.
Katie used to get dressed in the bathroom after a shower. But a couple of months back, started coming out in just a towel, grabbing her clothes out of the laundry basket & then heading off to her room to get dressed.
One night when she went to grab her clothes, her towel came undone & half fell off her. I pretended not to notice & made no mention of it to her. However I did notice she was completely shaved. I also saw her size E boobs for the first time. They just sat there, no sag at all. Just nice & pert.
She quickly covered herself again & ran to her room.
I caught a few glimpses of her new underwear, as she wears baggy singlet tops & loose short shorts around the house. I started taking more notice of her.
One day I had to go to the bathroom, whilst she was in the shower. I announced myself, as we always do, to let her know I was coming in. The shower curtain wasn't pulled across completely & I saw her whole body, naked & wet. I instantly felt a tingle downstairs. I was annoyed at myself for thinking what I was thinking. I mean this girl calls me dad for Christ's sake.
I told her the shower curtain was open & said sorry. Katie just said, 'That's ok dad. Don't stress. I didn't realise it wasn't shut.'
One night I walked through the house to lock the doors before bed. As I walked past her room, I heard heavy breathing coming from there. The lights were off in the hall, so she didn't see me. But her door was slightly open & her bedside light was on.
I couldn't help myself. I looked through the 5-6 inch gap in the door & saw her. Legs spread, playing with herself. I had never really thought of Katie doing that, but there she was, one hand playing with one of her breasts under her t-shirt, whilst the other one worked her pussy & clit.
I stood there for about 5 minutes watching in the dark hall. My dick had gotten hard & found myself stroking it through my shorts. I watched as after a while, her back arched, she closed her legs around hand & she started to shake a little. I knew I just watched my step-daughter have an orgasm.
I quickly scurried off to my room, forgetting about locking the door & climbed into bed next to my wife. She was already asleep naked, laying on her side. I grabbed some lube out of the side drawer, rubbed it over my dick & pushed it straight into my wife's sleeping pussy. She woke up pretty quickly, with me fucking her from behind. 'What's gotten into you?' she said, as she reached back & grabbed my arse to pull me deeper into her. After watching Katie & stroking my cock, I only lasted about 3 or 4 minutes, before a slammed my dick deep into her pussy & exploded. Kassy pulled away from me, rolled over & cleaned my dick of both of our juices, with her mouth, then said goodnight & went back to sleep.
The next morning, I said good morning to Katie, she smiled a cutsie smile & then left for school.
A few days later, I gathered all the dirty washing up out of the bathroom to take to the laundry. On top of the pile I picked up was one of Katie's new bras. I leaned my head down & smelt her worn bra. Such a fragrance. I knew I was home alone, so I dropped the bundle of clothes, except for that sexy, sweet smelling E cup bra. I pulled down my shorts & started stroking my cock, why holding her bra over my face & breathing in the sweet aroma. I masturbated harder & quicker, until I felt that urge come on. I held her bra up to my cock & blew into one of the cups. It looked hot seeing my load soaking into her bra. I quickly cleaned myself up & took the washing to the laundry, being sure to have that bra in the first load that went into the machine.
I always pick Katie up late at night, when she works her casual job. Plus I take her on all of her driving lessons. So we talk a lot & sometimes she confides some pretty personal stuff to me. Like I knew she was a virgin, as she told me the one boyfriend she had last year, hit her up for sex, she said no & he dumped her next day. She hasn't had a boyfriend since. She told me, 'when I'm ready I'll know. But not yet.' Good girl.
About 2 weeks after the hallway incident, Katie asked if I could take her for a night driving lesson for the night practice. I agreed & we grabbed the keys & headed off. She'd been driving for about half an hour with general chit chat, when Katie says to me, 'You know how I haven't had sex with anyone yet?' I was a little taken aback, but said 'Sure & good on you for not rushing into anything.'
