Warning: the following story contains graphic descriptions of very casual sex. If that is not to your taste, I would suggest you read something else. This is all complete fiction. I would never condone or tolerate in real life the behavior described in this story.
All characters are over 18 years of age.
I would recommend reading the previous parts of the Evolution series before you continue, as you may enjoy it better if you know the full backstory.
-----------------β-------------------------------------------------------------------------------------------------------
Ben returned home just as Carla and I were walking down the stairs after our shower together. Carla has dressed in her blue and white summer dress again, and was still fixing her white bra straps back into place over her shoulder as we came into the kitchen.
I have just spent the last 30 minutes screwing my son Ben's 19 year old girlfriend in the shower. It's not the first time I've fucked her, that was last Monday in the gym. But she was just a stranger then, when I had no idea she was dating Ben.
To my credit, I thought she was at least 25, maybe that was due to the dim lighting in the gym. When I discovered yesterday that she was just 19, I was in shock. I have never had anyone that young since our world changed 3 years ago.
At first I was mad at myself, a bit grossed out even. I mean, I have a 19 year old son, and an 18 year old daughter. The idea of fucking someone the same age as them, didn't really appeal to me. But let's just say I've come around to the idea, especially now that I've tested Carla out again knowing her age.
Carla and I go our separate ways in the house now. Carla goes and sits down on the sofa with Ben to watch some TV and chat. I grab some coffee and breakfast in the kitchen. Laura joins me shortly after, and I ask her if she would like one too. She does, so we sit down on our high stools together. I'm a bit apprehensive about Laura's reaction to what happened with Carla. I've never had sex with anyone else in the house before apart from her. She has though, many, many times. Not with her son's girlfriend, but still....
There is silence between us for a minute or two, but then Laura starts talking about the usual things we chat about every day, like what we will have for dinner that evening, news about our neighbors, general stuff like that. Everything is back to normal, as if nothing happened.
-------------------------------------------------------------------------------------------------------------------------
"It's almost 1pm," Laura says. "Jean and Pete will be here soon. I better make a start on lunch."
"I almost forgot they were coming over," I say. I didn't almost forget anything.
"Hey Ben, will you and Carla be staying around for lunch? Dad's work friend Jean and her husband are coming over at 2," Laura raises her voice so Ben will hear her.
"No thanks Mom, I'm going to drop Carla home soon, so I might hang out there for a little while. But I'll be back later. I can say "Hi" to them then if they are still here," Ben answers.
"Have you seen Claire today?" I ask.
"No, I haven't actually. She must be studying in her room again," says Laura.
"I better go check on her, see does she want something to eat," I say.
-------------------------------------------------------------------------------------------------------------------------
I knock on Claire's bedroom door, and wait for her to answer.
"Come in," she says a few seconds later.
"Hey Claire, just checking you're OK?" I say as I open the door.
"I'm fine Dad. Just getting some work done for the test tomorrow," she says.
"We're having lunch at 2pm when Jean and Pete get here. Will you take a break from your studies and join us outside then?" I ask.
"Yep, sounds nice Dad. Count me in," she says.
"Perfect, I'll let your Mom know. See ya then," I say as I close the door behind me.
I walk back to the living room and notice Ben and Carla have left.
-------------------------------------------------------------------------------------------------------------------------
Jean and Pete arrive at 1.50pm. I've worked with Jean for the past 11 years. She's 51, and her husband Pete is a little older at 54.
"Hi guys, thanks for coming over," I say when I open the front door before they knock, holding a hand out for Pete to shake, which he takes.
Then I give Jean a hug and a kiss on the cheek, as Laura stands behind me in the hallway.
"Hey Jean," Laura says, and gives her a hug. "Hi Pete, great to see you again," she says then, giving him a hug too.
"Laura, you look amazing. I love your outfit," Jean says to my wife.
Laura is wearing a pair of white knit short shorts, and I mean really short short. On top she has a pale blue spaghetti strap top, that just about covers her tits. She looks amazingly hot. Laura is dressed like this on purpose of course. She is showing Jean what she has to compete with, and is laying down a marker. Pete will have to sit down soon I would imagine. His eyes are glued to Laura, and I'm sure he is struggling to hide his erection already.
Jean obviously knew the game plan for today, and she came dressed to impress too. She is wearing a short and form fitting cream colored casual dress. It's sleeveless, with a nice plunge down the front. It's made from a light stretchy material that clings so tight to her body, it leaves very little to the imagination. The way it sticks to her little pot belly is unbelievably sexy. It shows how confident she is in her body, and is turning a part of her that other women might try to hide into another asset. Her tanned legs are on show as usual, with her snug fitting dress coming to just above mid-thigh.
I'm so accustomed to Jean in her business-like clothes she wears to work, what she is wearing today is rare for me to see. I like it. If she intended to make an impression on me, it's working. But I suspect it's more for Laura, Jean knows I would screw her in a bin liner. Jean is intimidatingly hot. You just know by looking at her that she could chew you up and spit you out. And you would love every second of it.
Laura leads Jean and Pete out to the back yard and they all sit around the outdoor table. I get the drinks after asking everyone what they want. There's a lot of small talk about how nice the weather is, what the kids are doing, shit like that. I've relaxed a little bit, as Laura seems to be very at ease with Jean. They're getting on really well, and it doesn't seem to be an act, by either woman.
