[MF] Family Vacation and my M(36) sister-in-law F(28)

****EDIT****

*I wanted to address the situation of accusations of me being a pedophile and stalking a 13-year-old. This story is loosely based on a true story. I’ve taken the liberty to change names, dates, and timelines in this story especially. What I didn’t do was some simple math and with years and such. I “met” my sister-in-law AFTER she graduated HS when her and my BIL began dating. They had been together for about 10 years or so the first time my SIL and I hooked up.*

*Maybe I shouldn’t have let the comment bother me as much as it did, but child predators hits a sensitive spot for me and I was actually pissed off about the comment….not at the person for commenting, but at myself for being so careless in my writing and potentially developing a very bad scenario.*

*Down vote if you will….it would be well deserved and I’m taking this as a lesson learned*

I can’t deny being keenly aware of my attraction to my sister-in-law since day one of meeting her, even though she was eight years younger. And in the 15 years I had known her she was always slim, with long legs, long dark hair, and a bum that just craved to be squeezed. In her younger years, she was never blessed with big boobs. They were petite B-cups at the most, but they seemed to fit her slim frame marvelously.

Things between Tammy and I changed during a family vacation. A couple years ago, my wife and I decided to take the kids back “home” and spend a week at my mother-in-law’s who lives in the middle of nowhereville, not to mention her installing a pool a couple year prior to that.

What my SIL and I have in common is that neither one of us were ever really accepted into the family and we sort of bonded with that fact of being the outcasts. The difference is that my wife and I moved out of state when we married and my poor SIL lives 10 minutes from my overprotective and obnoxiously meddling MIL.

My SIL and I always joked around, and mildly flirted with both of us rolling our eyes when our MIL would dictate or make comments. Or we’d wink at each other when the other was getting ridiculed about something.

One day while on this vacation, Tammy came poolside wearing a modest bikini and I noticed that the years, and a kid later were kind to her. Her small apple sized titties had grown into a fine pair of softball sized breasts. I couldn’t help but appreciate the view from behind my sunglasses and my cock also took notice and grew in appreciation admiring her from head to toe.

It was later that afternoon, when her and I were at the pool with the kids while our spouses remained inside talking to our MIL that things “changed” shall we say…

We began playing a game of basketball with the kids, and hands seemed to find their way underwater and accidentally graze over bare flesh or our bodies were smashed together while playing.

It became apparent to me that she could possibly entertain the idea of something more happening when she backed into me, “trapping” me against the side of the pool. Her ass pressed into my groin and moved in a flirty yet seductive way. It was then when my hands found and gripped her hips pulling her back. I was rewarded by her pulling forward just enough before she allowed me to pull her back into position.

With my hard cock being pressed back and forth against her ass, we kept this simulated fucking motion up for a couple of minutes until I finally took a deep breath, pushed her away from my groin and said I needed a break to cool down, “or else.”

She followed me out of the pool and asked me about what I meant about “or else.”

I told her if she and I would have been alone in the pool she would have felt what I meant, to which she replied “Promises, promises.” before wrapping herself up in a towel and going inside.

Later that evening, my wife, MIL, and me were sitting in the house when my SIL called. Since my brother-in-law worked nights, she was home alone and evidently her son came down with swimmers’ ear. She asked my MIL if she had any drops for it. After my MIL scolded her for not having proper meds in the house to take care of things like that, I volunteered to run to the drug store and pick some up.

I get to my SIL’s and I’m greeted with a hug and something along the lines about what a life saver I am. She grabs me a beer before heading back to tend to my nephew, and then her and I sat on the couch. Neither really brought up the events that unfolded earlier in the day, but there was no mistaking the unspeakable sexual tension that hovered over us.

We had been on the couch for about 20 minutes or so when she went to check on Larry, my nephew, again. Coming back a short while later,

“He’s sound asleep. I think he was exhausted after playing so hard today.”

“I completely understand that. It was a pretty exciting day.” There was a silence that followed. We both looked at each other.

“Want another beer?” She asked.

“Nah, I’m good.” I replied and our eyes never blinked while we continued to stare at one another pondering on the comment I had made.

My SIL began making her way to her seat on the couch, and when she passed in front of me, I grabbed her by her wrist, stopping her in her tracks. She looked down at me and all I had to do was nod my head up and down.

Tammy straddled me where I sat. Our mouths met and tongues wrestled. Over the next couple of minutes, nothing short of unabandoned lust could describe what we were doing to each other. Having two handfuls of the ass I had always admired from afar, Tammy gyrated her hips, grinding her crotch into the hard bulge in my shorts.

Panting and soft moans could be heard before Tammy slithered off my lap, kneeling on the floor in front of me.

“You have to be quiet. He shouldn’t wake up but…” My SIL let her unfinished sentence trail off while her fingers unbuttoned and unzipped my shorts before she took ahold of the waistband and pulled them down my thighs.

The next moment my head fell back, and my eyes closed enjoying the warmth of Tammy’s mouth descending my shaft. For the next few minutes, my SIL’s head bobbed up and down taking me to the edge. When I was at the breaking point, I reached up and regrettably pulled her up and off my cock.

We switched places, and I pulled the gusset of her loose-fitting shorts to the side since it was my turn to enjoy the sweet flavors of my SIL. I devoured Tammy’s wet, bald cunt causing her to writhe in pleasure.

It wasn’t long before I heard “I’m cumming” in a whisper, and I doubled down on my efforts attacking her clit with my tongue. Tammy’s body went taught and she gripped the edge of the sofa cushions tightly.

I continued licking the results of her orgasm slowly until I felt she had calmed down enough. When her breathing slowed, I moved my hips between her open legs and again I felt the heat around my cock as I penetrated my SIL.

“Oh my god I need this.” I heard her say in a low and sultry voice.

My hips moved back and forth, thrusting in and out of her body and our mouths met again in a heated but short kiss. I pulled Tammy’s tee shirt up and over her head exposing her bra. I quickly reached around and found the clasp, removed the garment completely, and dipped my head until my lips found her hard nipples and I suckled another trail of moans from Tammy.

By this time, carnal heat was taking over. I reached down, grabbed the backs of her thighs, and pulled her legs up, hooking the back of her knees into the crook of my elbows. I opened her legs wide to prepare for the fucking I was about to give her.

Flesh slapping flesh caused a steady cascade of grunts and moans and a few “oh yes, oh fuck yes” statements while we hurled our way to the inevitable.

When Tammy began her climax, I could feel her pussy tighten around my shaft. The noise she made started low but built into a crescendo that matched what her body was screaming.

“I’m going to cum.” I grunted in gasped breath, and she wrapped her legs around my waist and pulled me in tight.

Still inside her, we laid in silence with my head resting on her naked chest, breathing heavy from the intense orgasms we shared.

When our bodies and minds calmed down. I pulled my still semihard cock from her filled hole. The results oozed out, down her ass and across the edge of the couch before pooling into a puddle on the carpet of the floor. “I’ve got to get me, and this mess cleaned up.” Tammy said.

“I probably should get back to the Dorothy’s before she accuses me of something I might or might not have been doing.” Tammy slapped me before pulling her tee shirt back on.

“See you tomorrow?’ she asked as I was leaving.

Probably tomorrow and any time after while we’re visiting if you’re up for it.”

“I’d like that” Tammy said before she wrapped her arms around my neck and kissed me goodbye.
