*Thanks everyone for the great feedback and comments! Here is another adventure for you all to enjoy!*
Ever since my oldest step-daughter (Krystal) and I had our first sexual encounter, she has been non-stop wanting to try different things. Not that I am complaining, but I find it hard to keep up with an 18-year-old hottie that just has a desire to try everything sexual, all at once! We have talked, and she has had sex before me, however, she complained that most guys wanted to get their needs met, but left her always wanting more. Our encounter was the first time she has ever been fulfilled, so she wanted more... A LOT MORE!
Since that day, Krystal has transferred to a closer school and is living at home with us again. Everyone was happy with that since my wife has her baby girl back, our youngest daughter has her big sis back, and I was able to relive that day in my mind every time I looked at her.
Today started a lot like most other days. My wife went to work, Krystal and her sister went to school and I decided to have a quiet work from home day. It was a very light day for me, only 2 meetings and Krystal only had an hour long class today. She made it very clear that she had something special planned for later this morning if I was "up" for it. Giving me a quick peck on the cheek and squeeze of my hardening cock, she bounced out the door. My cock has been rock hard and twitching since she left me with that thought! I never realized how much willpower I had until that day. Throbbing cock, Internet full or porn and no wanking off for the next few hours as I thought about our next encounter!
I thought that the morning would just drag on, but work became pretty brutal and time passed much faster that I anticipated. I heard Krystal pull up and park, my cock immediately remembered the promise from this morning before my brain even registered and started a huge bulge in my shorts. Krystal came in all smiles wearing a loose fitting outfit which I found odd from her normal attire. She bounced over to me and gave me a kiss while reaching down and grabbing my throbbing cock, and asked when I would have time for her "treat". At a loss for words, I told her to give me 10 minutes and I'm all hers.
With that she ran upstairs and told me to text her when I was ready and then to head up to her room.
I quickly finished up my work and sent her a text bout 15 minutes later. I was shaking from the thought of her waiting for me with a "special treat". She immediately sent a response of "cum on up, knock, close your eyes and enter". I had never played this kind of game and what she had in mind was beyond anything I could comprehend. All I could think about is that I had a hot, sexy, horny 18 year old sex-pot waiting for me to rock her world!
