My name is Dave. I'm in my late 40's and live with my late wife's 26 year old stepdaughter, Katy. My wife passed away 5 years ago and it was a difficult time for both Katy and I. Katy was 10 when i got together with her mum, and 18 when we married. I never used to have any inappropriate feelings for Katy, but that started to change about 18 months ago. I'd found my libido starting to return after the loss of my wife, but having been out of the dating game for so long, I had no outlet for my building passions other than the internet and my right hand. I'd also started to notice how Katy had become a fine, young woman who dressed to show off her incredible body. I started to find myself straying into Katy's room whenever she was out of the house. I loved rummaging through her lingerie drawer, she had lots of very sexy underwear, all sorts of types of panties in every colour and material that you could imagine.
One day I found a pair of crotchless panties at the back of the drawer, that was probably the tipping point for me, as I realised that not only was she sexy as hell, she was also slutty too. I spent more and more time in her room, using her underwear as masturbation aids and imagining what she looked like in them. Whilst wondering around her room one day, with a pair of her panties wrapped around my cock, I decided to look in her bedside drawer. I opened it and wasn't surprised to see a 6 inch silver vibrator laying on top of a pile of paperwork. I listened carefully to check there was no sound or movement in the house and reached for it. Many thoughts went through my mind. I knew I'd already crossed a line, but could I cross another? I really wanted to, but I knew that I shouldn't. My mouth was dry, my palms were sweaty and my heart was racing as I brought it up to my lips. Before I knew it, my lips had parted and I was sucking on her vibrator. As I realised what I was doing, my cock started to twitch, this was all too much excitement for me. With trembling hands I was quickly able to get her panties away from my pulsing dick and catch my cum in my hands. A close one! I would certainly have struggled to explain why I had cum all over her knickers. Now I felt guilty, I quickly ran to the bathroom to clean up, before returning to her room to put everything back where I had found it. I carefully checked to make sure there was no possibility that I'd left anything out of place before leaving the room and closing the door behind me. I spent the next week trying to put the experience out of my mind, but I couldn't, it had been so exhilarating, if anything I wanted more. My opportunity came on a Friday evening when Katy told me that she was going to meet a friend on Saturday morning and they would be going to Manchester for the weekend. I hardly slept on Friday night, my mind was full of thoughts of how I would spend the weekend.
After sleeping fitfully, I awoke around 7am with a raging erection. I'd normally stay in bed and have a long weekend wank, but not this weekend. I wanted to make sure I was horny for what I had planned. I lay on my back, closed my eyes and visualised Katy in her lingerie as I gently stroked my cock. It only took a few minutes of edging before I was at serious risk of blowing my load. I jumped out of bed and went into my ensuite bathroom for a cold shower before heading downstairs for breakfast. I was half way through my toast when Katy breezed into the kitchen.
She looked at me and said, "Good morning, I'm heading off to Beckys soon, we'll have breakfast at hers before setting off to Manchester. I'll be back on Sunday afternoon at the earliest."
I replied, "No problem, you go and have a great time." Little did she know that I planned to spend most of the weekend in her bedroom jerking off with her panties. I impatiently fidgeted and aimlessly scrolled on my phone as I finished my breakfast while wishing she would hurry up and leave.
"Ok Dave, I'm off now," she called cheerily from the hallway, before I heard the front door close behind her.
