Wife's sister comes to visit

My wife’s always been the only one I’ve really had eyes for. The one exception? Her sister. They were cut from the same cloth, just stitched differently. They mirror each other but are also different in so many ways.

My wife is a tall, skinny, busty blonde with sharp green eyes — a bit of a wild card. That party-girl edge never really left, even after two kids. She’s chaotic and unpredictable in all the best and worst ways. A slightly unhinged stay-at-home mom who drinks a little too much, hair always a mess, constantly five steps behind but somehow still making it work. Disorganized, emotional, barely holding it together most days. But on the other hand, she’s also a freaky, fun-loving filthy drunken slut.

Her sister? Total contrast. Brunette. Brown eyes. Smaller tits, but with a tight, round ass that definitely edges out my wife’s. More polished, more composed. She’s the kind who’s up at 5 AM, dressed to the nines, makeup done, house spotless.

It was 4th of July weekend and my wife’s sister and her family were visiting from out of town. Our neighbors were on vacation and let our family use their pool in exchange for bringing in the mail. We took full advantage - enjoying some sun, some food, some drinks… of course, what I was enjoying the most was sitting back and admiring the beautiful view — my wife’s sister’s ass in her one piece. Even with her husband and my wife standing right there, I could not take my eyes off her.

We realized we needed some things back at the house so I started heading back to get them and my wife’s sister volunteered to help me out. We walked together and made small talk. I opened the door for her and followed her in. She went up the stairs in front of me, that tight round ass teasing me with every step.

We gathered some stuff. She bent over to grab something out of the fridge, and I had to squeeze by. I placed my hands on her waist, brushed against her — my bulge clearly pressing into her. She felt it and popped up a bit, then froze. Then turned her head with a playful smirk.

"Watch it, big guy."

I grinned and leaned back against the counter, watching her move around the kitchen.

She came over toward me, reached up for something, lost her balance slightly, and I caught her by the hips. Her body pressed up against mine a bit. Her hand landed on my chest. We paused there and my hand slid down to her ass and I held her there. Tight.

"Oops," I said with a smirk. "You alright?"

She didn’t answer at first. Just ran her fingers down my torso, right to the bulge in my swim trunks — now fully hard. She palmed it through the fabric and looked up at me, biting her bottom lip.

"Yeah thanks. You doing alright there?" as she gestured with a head tilt down toward my cock.

"Just fine." I smiled as I got a bit more handsy with her.

"You’re so bad." she said.

I said nothing. Instead I pulled my bathing suit down and placed her hand on my bare cock. Her eyes widened a bit with shock. She started kissing on my neck and then dropped down to her knees and before I knew it, she was taking me in her mouth.

Her big brown eyes looking up at me were familiar but different. Her lips were a lot fuller than my wife’s and looked amazing wrapped around my shaft. I popped her bathing suit straps down to get a look at her tits. Smaller than my wife’s but a bit perkier. I squeezed them together and pinched her nipples. She let out a moan with a mouth full of cock.

I couldn’t believe this was happening with the rest of our families 50 feet away and able to walk in any second. I felt myself getting too excited and needed to stop her.

I picked her up, turned her around and had her lean over the counter. I slid the rest of her bathing suit off. We were now ass naked in my kitchen. I kissed her shoulders and reached around with one hand to grope her tits while my other hand slid down and started to play with her clit.

She let out a moan and told me she wanted me inside her. I pushed myself in slowly and she tensed up as she took my cock in her eager pussy. Her ass and curves looked incredible as I took her from behind.

There was no build up. I took her fast and hard. It wasn’t long before she came hard for me and squealed in pleasure.

She asked me where I wanted to cum. My mind raced with all the different options. Should I slut her out and cum on her face? Her supple tits? Her big beautiful ass?

Too late. The decision was being made for me. She picked up the pace, throwing herself back on to my cock skillfully and I couldn’t take it anymore. I unloaded deep inside her raw married pussy.

We let out some laughs, got dressed and went back over to my neighbor’s.

"What took so long?" her husband asked.

She smiled at me. "He got a little handsy."

Everyone laughed. No one had a clue.
