I’m so obsessed with my wife but if there’s one other woman who has always caught me eye, it’s her sister. They’re like the best of both worlds. My wife has dirty blonde hair, stunning green eyes and incredible natural DDs. Her sister has dark features, more supple breasts but a really tight ass and nice full lips. She’s also much more “put together” than my wife is. My wife has more of that broken, party slut energy .. one look at her and you can tell she’s a dirty little whore who has had her share of cocks. Her sister is a bit more buttoned up. I’ve always wondered how she is beneath that facade.
There’s definitely always been some very subtle flirtatious energy between us. We’ve always been open when it comes to talking about sexual shit. When we hug I pull her in nice and close so it’s less of a family hug, and more of me pressing my cock against her pussy with my hands on the small of her back. When I brush past her, I place my hands on her in suggestive ways. We lock eyes from across the room sometimes in that certain way. One time, during another family visit, we were hanging out late and then when we finally turned in, I was stroking it to pics of her on IG and accidentally hit like and i think she has an idea of what I was up to.
But at the end of the day, she was always loyal to her husband and I was always loyal to my wife. But that all changed this weekend.
We flew in to visit her family for her dad’s birthday and we stayed with her sister’s family part of the time. I couldnt stop checking her out. Her skinny little legs with that thigh gap and her tight little ass in her leggings. Her big eyes and nice full lips every time she smiled at me. Her long straight hair and just how she carries herself really.
The tension between us was definitely a bit higher than usual. Inexplicable but just a strong energy that made me decide I needed to have her.
One day, we were all getting ready to go out for their dad’s bday celebration. My wife and brother-in-law took our little ones outside to play and my sister-in-law and I were starting to get ready. She offered me the shower in the master bath connected to their bedroom bc it’s a lot nicer. She knocked on the door and poked her head in while I was in the shower.
“Sorry - I just need to grab some things.. not looking!”
She was rustling though some drawers when I decided to go for it. I opened the shower door and just stood there for a moment. Her eyebrows raised in shock as she looked at me through the mirror as I stood there with my hand on my cock.
“Did you want a turn?” as I gestured behind me to the shower.
She blushed and laughed “Oh my god, what are you doing? Stop!” and tried to play it off like she was embarrassed and leaving the room.
I grabbed her by the waist and pulled her in without saying a word. I placed her hand on my cock as it began to grow and our lips got close. “Come in with me” as I went in and kissed her neck. She responded with a firm grasp around my pulsing shaft. She was in some skimpy little PJ set with short shorts and a loose shirt with her tits hanging freely. I unbuttoned her shirt slowly as I kissed her neck, and then ripped her shorts down quickly.
I went in and kissed her lips passionately as I palmed her beautiful tight ass with both hands an gave a nice good squeeze, picked her up an brought her into the shower with me.
Our warm wet bodies pressing up against each other felt amazing. I stuck my cock right up against her pussy lips and slid it back and forth.
“Mmm I fucking want it” she moaned.
She pushed me back against the wall and wasted no time. She immediately took all of me in her mouth. She looked amazing with those big brown eyes, and those beautiful full lips wrapped around my cock. The water soaking her as she slurped on my dick was a beautiful sight. I closed my eyes for a brief moment to really concentrate on how it felt. Comparing her mouth to my wife’s, comparing their technique and skill. Then I opened my eyes to continue witnessing this amazing little cock sucker in action. I reached down and squeezed the nipples on her supple little breasts and she let out a moan with her cockfilled mouth. I reached down to smack her ass and shoved my cock a bit deeper down her throat.
“You’ve been waiting for a turn with this cock haven’t you?” I said as I smacked her ass one more time.
“Mmhmm!!” she tried to speak with her mouth full as she picked up the pace. She put her fingers in between her legs and started playing with herself.
Fuck it felt so good. I just stood there and let her continue on until I was near the end. Once I was there, I knew how it had to go down. I took my cock out of her mouth and smacked it around on her face and tongue a bit. She knew what was coming. She opened her mouth wide, stuck her tongue out and patiently waited for my nut, looking up at me with those big beautiful eyes. I couldn’t believe I was about to cum on my wife’s little sisters face. That thought, and that sight, made me unload one of the biggest loads I ever shot off in my life. I covered her and she loved every second of it. She washed it off, stood up, rubbed her ass against my dick an left the shower.
Now I know that my innocent looking sister-in-law is just as much of a slut as my lovely wife, if not more.
