My wife's cousin is a Native American girl with long dark hair, a decent body with somewhat small tits, but she has a nice big butt on her that makes me lust every time I see her (which is quite often).

She walked into our house for the first time of the summer with a plate of brownies and personally handed me one as I sat in my rocking chair watching tennis on TV. Our hands touched, which may seem like a small thing, but every time we touch, sparks fly (at least on my end).

The cool thing is, my wife and this cousin of hers are really close and they like to do a lot of things together. Which means she comes over a lot. On this particular day, she had planned on staying the night.

The three of us swam in the small pool in our back yard that afternoon and I caught glimpses of her ass and tits every chance I got (without my wife seeing).

That night, she changed into the thin, silk nighty shorts that are so loose they leave little to the imagination when she sits on the couch with her legs crossed. I never actually see anything, but I see almost everything. I wonder if she wears panties under them, but I'm pretty sure I know the answer since every time she bends over, the silk sucks up into the big crevasse of her bottom and I see no underwear lines. It's possible she wears a thong.

When she stays over, she has her own bathroom in the back of the house that connects to the guest room, and the next day when she and my wife went out shopping, I snooped in her bedroom and found those skimpy silk shorts tossed into a corner.

Hands shaking (this is the most intimately close I'd ever been to her, and I prayed she left a scent behind), I sniffed in the ass of her shorts, and let's just say I got my confirmation that she does NOT wear underwear beneath them—That was some nude booty at its finest! I felt my cheeks flush as I inhaled her scent (blood ran to my head) and my cock rose to full mast beneath my shorts.

Alone in the house, I took her shorts into her bathroom and began to masturbate leaning over the bathtub. I had a crazy idea. I've always had exhibitionist fantasies, but I'd never done anything as bold as I was about to do.

I kept my nose in her ass as I continued to stroke my cock, and imagined it right there in front of me, clapping to the beat of my strokes. When I felt the warm climax building from deep within after only a few intense, heart-pounding seconds, I stepped over the edge of the tub and ejaculated (short desperate bursts) onto the hot water knob.

I knew she would put her hand in my jizz later, and that thought turned me on so much that my cock didn't want to return to its normal prone position. It was fool-proof—There was no proof. I could deny everything, but at the end of the day, she would know what it was. And even if she didn't, she would at least be thinking of my cock.

I returned her silky shorts to the corner where I had found them and waited for them to get home.

The next morning, she asked me if I wanted another brownie, but the way she said "brownie" seemed a little forceful or mocking, like there was something behind it. Maybe it was just my imagination. We swam again that afternoon and drank a few beers in the garage, and no one acted weird in the slightest.

A few weeks passed, and she invited us over to her apartment to swim in the pool one afternoon. By now it was mid July.

She kept finding reasons to climb out of the pool in front of me, her crack showing every time, and she would tug her bottoms up into her crack before pulling them out again. All I could think about was her ass. With my wife so near by, it was exhilarating!

She kept dropping things and bending over to pick them up. I imagined her brown eye staring out at me through her bikini bottoms, keeping an eye on me and the effect she was having, like her own private spy.

Had her bottoms ripped up the middle, we would have made eye contact. Maybe it would wink at me.

Such were my horny thoughts as I treaded water and thought of little else...

A week or so later, I decided I would play with her like she was obviously playing with me (or maybe it was my imagination).

I walked into the living room once and stretched while she was sitting on the couch on her phone, and I had made sure beforehand that I had a semi hard cock that stuck out from my leg. I acted like it was no big deal, and I definitely heard her chuckle. When I looked at her, she was smiling a little, still looking down at her phone, and shaking her head.

Later that afternoon, in the kitchen, she set her phone down on the counter near where I was standing in front of the coffee pot, and I saw an ass pic she had taken (it was just her naked butt cheeks as she looked back over a shoulder). I only saw it for an instant before it went to the lock screen, but she jumped back for it like I had seen something on accident.

"Jesus Christ," she said, or something like that, as she glanced back over her shoulder at me on her way to the back door.

It was that afternoon that we were sitting out in the garage, having a few beers, when my wife decided to make a coffee run.

I remember that I had commented how smooth her legs looked and she'd asked me to feel them in a small, somewhat shy voice (Which was weird, because she is not a shy person). I had felt them, and then, knowing my wife wouldn't be gone long, I just asked her straight up if I could see her ass for real.

She grinned shyly and looked down, then right back up at me. We held eye contact for a long time after that.

She stood and took my hand, guided me through the door to the side yard.

She dropped her drawers, bending all the way over as she yanked her shorts and panties all the way to her ankles.

She placed both palms on the hot brick wall of the house as the afternoon sun blazed down on us, and I fell to my knees to get my first sniff of the real thing.

My cock rose to attention.

Without thinking (we probably had 5-7 minutes left), I tugged down my own pants and my stiff cock flung up over my underwear band.

I squatted up into her (she's shorter than I am) and thrust up between her ass cheeks; she yelped when my cock head nipped her butthole on the first thrust.

I didn't have any lube; I just squatted there thrusting upward into her crack again and again, feeling the friction, feeling the softness of her little eye (that was even darker than the rest of her, by the way) as I pushed against it again and again.

We were both sweating, humping, knowing my wife would be home any minute, desperate to cum.

Looking back, I know I could have put my cock in her—I know she wanted it—but there was something even hornier about dry humping her butthole, and when I felt the orgasm coming, I let go completely.

I thrust up into her crack a few more times and then shot the most powerful, desperate bursts of my life straight up her back and into her hair.

I wiped my ejaculate off the small of her back as my wife pulled into the drive, and then ran around back while my wife's cousin went back into the garage as if nothing had happened.

I immediately went and masturbated to the smell of my wife's cousin's ass on my cock and busted again all too soon.
