So my wife and I have been married for a year, and our marriage is great... Besides in the sex department. She loves sex to be sensual and slow and vanilla for the most part, but I love being absolutely primal and filthy and naughty in public... So sex is less frequent than either of us wish.
Then came Thanksgiving and her sister Claire's 18th birthday.
My wife and I are just sitting on the couch when I get a text from Claire. It's a mirror selfie of her in a tight red corset on her knees, with the caption "just begging for a little attention"
I freeze.
Then a moment later she sends back "oh shit! Sorry, wrong person!! Don't tell Alice!"
Thank God. I genuinely thought she was trying to flirt with me. That would've been bad... Right? I start to think about what she looks like under that corset and find myself thinking about her like I never have before.
I text back "worse things could happen! Your secret is safe with me!"
Still fantasizing about Claire, I walk over to the bathroom to shower. After stripping down I get another text from Claire.
"What if I actually sent it to the right person?"
She is flirting with me... And my unrestricted cock is becoming rock hard at the idea of fucking her.
I step into the shower and jerk off imagining her body. I cum thinking about finishing in her and the clarity hits - I can't do that to Alice.
I text Claire back, telling her I can't do that to my wife.
But Claire had different plans.
The next week I wake up to increasingly thirsty texts and pictures. I tell her it can just stay a virtual affair - an easy compromise to hide.
But it seems like that wasn't enough for her.
Home again for the holidays, I'd catch Claire looking me up and down and touching my body when we were alone.
One evening we were setting up the Christmas tree when I was asked to go find some ornaments in the basement. I venture down alone and start to look when I hear footsteps down. As I'm looking I mutter "I can't seem to find them...". Yet no one responded. I turn around to see Claire with her shirt dangling from her fingers and her petite breasts out. Without words she walks over to me and grabs my hands. She guides mine to squeeze them and I see her eyes roll back. She grabs my neck and our lips finally meet.
It's primal, it's filthy, it's risky.
And I'm immediately hard.
The moment of euphoria escapes us as we hear more footsteps. In one swift motion her shirt is back on and the moment disappears, but the tension doesn't.
We spent the next week making out whenever we could, yet it was never enough. We needed more.
So we came up with a plan.
My wife had a 2 hour appointment on Christmas, a window of time perfect for what we needed.
The appointment day came and Alice and I were getting ready to leave. I tell Claire to hide in the trunk as I "warm up the car". Alice walks out aloof to her sister and we drive there.
Alice kisses me goodbye and as soon as she's in the doors of the hospital I get Claire out. We climb in the back seat and put the car blinds up as the snow does the rest.
Within minutes her top is off again. It's going to happen! She grinds on my hard cock through my pants and I feel her eager.
She undresses completely and I'm too stunned by her body to realize I'm about to fuck my wife's sister on Christmas. Claire's perfectly tucked pussy is dripping wet and she grinds on me, leaving a layer of her grool all over me.
Before I realize it, I'm naked too and she's teasing her pussy with my cock. She makes eye contact with me and slowly puts just the head in... She's so tight already. What I think will be a long penetrative process gets cut short when she slams her hips down and my whole cock slides in all at once.
"Jesus Christ... Claire." I mutter, feeling her throb on me.
"Merry Christmas to me!" She says in moans as I grow bigger in her.
She starts to fuck me and before I know it she's nearly ready to orgasm. I feel her grip my edging cock even more tightly and I know I'm moments away.
"Claire I think I might..." But suddenly her hand goes over my mouth.
"You'll cum when I say you do!" She asserts, fucking me harder with muffled moans.
She starts begging as she nears another orgasm, yet I'm much closer.
I try to tell her I'm about to cum, but her hand keeps the words in. I feel her pussy tighten one last time as I cum inside of her. A week worth of cum inside her pussy.
She starts fucking me again, saying "if you're going to take my virginity, I had to make sure I got the full experience!"
I took her sister's virginity. The reality set in as I came inside her again and the clarity came through. I see a phone call come from Alice and pick it up with my cock still in Claire.
Alice tells me it went way faster and she'll be out in 5 minutes.
In a rush, Claire pulled me out and shoved a toy inside her, not a drop of cum escaping. She climbs back in the truck seconds before I see Alice walk out. I hear Claire turn on the vibrator and turn up the music to mask it.
The whole drive home I couldn't stop thinking about her pussy, how I took her virginity, and how I may have put a baby in her... Even Alice and I used condoms.
After we get back, I let Claire out and see her pants are soaking wet. She tells me she squirted in my trunk as she goes through the back door and up to her room.
That night, Alice and I are hooking up and I can only think about Claire.
I need her.
