My 18-year-old stepdaughter Linda had filled in for her mother for our traditional Valentine's Day date. As usually happened with my wife Jessica, this led to kinky sex. What did not occur was Linda giving me her virginity. It seems she had promised her mother that she would save her vagina for a very special man. Neither the stepdaughter nor I were confident that my wife would consent to me being that guy.
Jess had returned from her business trip, and as usual, I welcomed her home with mind blowing sex. It was made even more special by my recounting the adventures with her daughter. In spite of Jess having asked Linda to pleasure me on our date, Linda and I had not continued our activities in the days before my wife's return.
But I knew that Linda had an itch, so it was just a matter of time until she got up the nerve to suggest that rather than a boyfriend, she wanted me, her stepfather, to have the honour of being the first cock in her cunt.
I was silently a bit sad that Linda's talented mouth and tight young anus were not available in the interim. I loved all sorts of sex with Jessica, and we shared many positions and treats upon her return, but there was a freshness to sex with Linda that was special.
Fortunately, Linda did not tease me by flaunting her body around me, nor did she discuss sex in my presence. However, with Linda having told me that she wanted me to be her first if Jess consented, my libido was elevated, especially so whenever Linda was around. She could have dressed like a nun and still turned me on.
A couple of weeks after Jessica's return, my wife told me that she had arranged a special catered dinner the following Saturday, and that Linda would be joining us.
"To make it special, I asked her not to tell her friends, just to make up some excuse why she was staying home that night."
Jessica's tease made my horniness even more pronounced, and I sprung a hardon every time Linda was around. Jess noticed this, of course, and took advantage of the situation. By Thursday, we were both so horny that Jessica pulled my cock out of my sweatpants and gave me a quick lick while Linda was in the kitchen making popcorn. When my stepdaughter re-entered the family room, her mother swiftly tucked my aching organ back into my pants but remained kneeling at my feet. That got a look from Linda that suggested she was wondering just what she had missed. The rest of the movie was a blur to me, perhaps because all my blood was flowing to my littler head instead of my brain.
When Linda went up to bed, Jess did not even shift. She simply fished my erection free and took it into her mouth. She barely pumped her head down to my root and back up to tease the slit with her tongue before I gushed great gobs of goo. I tossed my head back against the couch as I came and was sure that I saw a quick movement on the stairs. It seemed like Linda was a voyeur along with everything else.
Saturday could not come soon enough.
Jessica was affectionate all week, teasing me with sexy lingerie and by brushing against me. But every time I tried to initiate sex, she said, "Save it for Saturday, big boy."
I noticed that a lot of this playfulness occurred when Linda was around, such as just as my stepdaughter was entering the kitchen, or while we snuggled under a blanket watching a movie with Linda.
You might have expected Linda to also be flirting if Saturday night truly was a set up to achieve her first time. No such luck. I was the one "accidentally" walking in on my stepdaughter when she was changing and ogling that fine young ass which I had already fucked at the restaurant.
Between the two women, I was walking around with a chubby all week.
Finally, Saturday arrived, and the caterers set up the meal in warming dishes, then left. They would return the next day to clean up. It was left to me to deal with them, as the women remained upstairs primping for our "date".
Jessica came downstairs first, wearing a gown I had never seen before, with a slit up the side all the way to her waist, and a lace bodice that made it obvious that she was braless. Her nipples were already excited.
In the moment while I was breathlessly anticipating Linda's entrance, Jessica's cell phone rang. She went into the kitchen to answer, then returned just as Linda appeared at the top of the stairs.
"That was the security company. There was a break-in at the office. I'm on call this weekend to go meet the police."
My disappointment must have been obvious on my face.
"The food is here already. You and Linda should have a nice date. I can eat leftovers when I get home. Hopefully I won't be too long."
My ears perked up at the mention of the dinner as a "date".
Linda was halfway down the stairs. Her outfit was a teenager's version of sexy -- a micro mini skirt barely wider than a belt, and a tank top that displayed her braless breasts. Her legs were made extra sexy by her four-inch stiletto shoes, which also tilted her pelvis in an enticing manner. Like her mother, her nipples were already erect.
Disappointment was also apparent on Linda's face.
"Don't fret, you two. Linda did a great job filling in for me on Valentine's Day, so I'm sure tonight will go smoothly."
I relaxed a bit and noticed that my stepdaughter's beautiful eyes had a naughty glint to them.
"I will do the best I can to fill in for you again, Mom."
"I know that my busy job is hard on both of you, but the fact that you get along so well is a relief."
Jessica already had her purse and car keys out and was walking to the door. Linda continued down the stairs, gave me a wink as she passed me. She gave her Mom a hug and a kiss.
"Hurry back," my stepdaughter instructed Jess, but as soon as her mother exited, Linda turned to me with a grin and a twinkle in her eye.
"Want your cock sucked?"
Not the sort of thing most men expect to hear from their stepdaughter, and not something that had happened since our Valentine's Day date. Like most men, I just nodded my head in response.
Linda unbuttoned her shirt, displaying her excellent cleavage, but not baring her nipples. She was such a tease. It made my half hard cock surge to fullness. Linda licked her lips.
"Is that for little old me?"
She stepped closer, reaching for my zipper. The sight of my cock pushing my underwear aside as it sprang free made her giggle. She looked like a woman but had the carefree spirit of a teen. I had to remind myself that she was eighteen and legal, if incest were legal, and if this was incest.
