FUCK! I had forgotten to turn the flash off!! I instantly dropped down and rolled around the end of her bed, hoping to be out of sight in case the bright light woke her up, seeing as how her face was in the line of fire, so to speak. My heart pounding and trying to stifle my heavy breathing as much as possible I silently prayed that she hadn't woken up or, if she had, she wouldn't notice my presence and would go back to sleep. After a few moments, I ascertained that Kim was still breathing heavy and I slowly crept back between her legs. Turning the flash off, I took several more shots of her pussy - noticing it was shaved smooth, or was as much as I could tell from my vantage and what was exposed - as well as some pics of her whole body sprawled out on her bed. I made sure to capture her smooth, toned legs and ass and her round calves and the curve of her soles. In addition to panties, I'm a huge leg and ass man to include more than a slight foot fetish and voyeur streak. So far, the evening was turning out much better than I had assumed when I found my wife sound asleep.
While taking the photos, my erection had stayed rock solid - encouraged with some casual stroking through my sweats - possibly harder than it had been in a long time, if not ever. When I had taken as many photos as I wanted, I got a little bolder and gently, ever so slowly, lowered myself onto the bed to kneel straddling her left leg that was extended straight back. I knelt down, constantly monitoring Kim's breathing, and placed my face to within mere centimeters of her pussy. I supported myself with one hand on the bed and with the other I gingerly pushed the leg of her shorts open wider, inhaling the pungent scent of her cunt and getting a great close-up view. The view was too spectacular to pass up, so I grabbed my phone from where I had set it on the bed and took several close up shots to enjoy later. She was mostly shaved, but not bald like I had originally thought. She had a slight tuft of hair above her clit; I could see it peeking out from between her pelvis and the mattress. A light dusting of blond peach fuzz also covered her plump outer labia. Her inner lips were a dark burgundy color and were tightly pressed together, peeking out just so slightly.
Satisfied that I had plenty of visual masturbatory material for later use, and really fucking horny at this point, I abandoned my phone and concentrated fully on enjoying the warm, tart scent of her pussy. Now that my right hand was free of my phone I resumed fondling my cock through my sweats while I continued to inhale deeply, savoring each breath. I was getting frustrated trying to stroke my raging boner through thick cotton so I gently got up from the bed and took off my sweatpants, laying them on the bed where I had been kneeling - now fully committed to rubbing out a load and wanting a place to deposit my spunk to avoid leaving any evidence behind.
I climbed back on the bed and resumed sniffing Kimmie's cunt as I slowly began to stroke my now free and naked cock. If I wasn't enjoying myself so much I'd scarcely be able to believe what I was doing! Intoxicated by the incredible aroma of her pussy and stroking my cock faster and harder - I didn't even bother with lube - I got carried away and, without consciously realizing I was doing it, my tongue flicked out and I ran it up the outside of her cunt from her clit to her asshole!
OH SHIT! Realizing that I had actually touched her I froze, fully expecting her to start awake and freak out. After a moment or two that felt like an eternity I was certain that she hadn't stirred. Once I got my heart rate back down to a non-bursting rhythm, I got bolder and gave Kimmie's cunt another lick - although much softer and tentatively this time. After four or five gentle laps I was convinced she wasn't going to wake up so I began licking a bit more aggressively, parting her lips with the tip of my tongue and drawing out her flavor. I was in heaven, savoring the sweet yet tart juice as I ate out my sleeping sister-in-law. Tightly constricting my tongue I probed as deeply as I could, rewarded with thick creamy juice when I withdrew it. I took a moment to savor it and then continued to orally penetrate her.
Obviously not having much sense to this point, I thought to myself "what the fuck, why not?" as I slid my right index finger into her vagina - it was nice and slick from my saliva as well as the apparently natural response to my tongue. I froze again as Kim softly moaned and slightly shifted on the bed, did she wake up?! I managed to keep myself from flinching and yanking my finger out, simply remaining motionless, albeit with a finger up her cunt, until I was sure she was still asleep. When I was, I continued to finger her pussy and added a second digit while I licked and sucked gently on her clit. That was a bit tough to do as it was almost resting on the mattress since she was face down; consequently I had to turn my head and rest the side of my face on the bed, pressing my left ear into the mattress. It would have been comical to see, me kneeling between my SIL's legs - ass up and face down almost in a downward dog, licking and fingering her sweet cunt as I furiously jerked my cock.
I couldn't take much more, my stroking became intense and my grip tightened as I began to reach the point of no return. I was vaguely aware of light moaning as my balls tightened and cum erupted from my cock as I tried to stifle my orgasmic vocalization, uttering a muted grunt rather than my normally much louder release. I spewed what must have been the biggest load of my life, but only partially on my sweat pants as intended - the first couple of ropes landed on the inside of her thighs, on her pussy, and a few splatters even hit me in the face.
Spent, I managed to resist the urge to collapse on top of her and lifted myself up and off the bed. Noticing the strands of cum on her legs and pussy, I went to wipe it off with my sweatpants but decided against it; still fearful that might wake her. Instead, I leaned back over and gently licked my jizz off the inside of her thighs and from the outside of her pussy. Even though I was still terrified of her waking up, at this point I really wasn't paying very close attention - no longer listening to her breathing or watching her face.
Satisfied that I had eliminated all traces of my spunk, and very satisfied that I had gotten to unload my balls to the sight, scent, and taste of my sleeping sister-in-law, I quietly turned off the light and opened the door to make my escape. As I was gently closing the door behind me I imagined I heard a muffled giggle. Or did I?
