Babysitting for my Aunt and Uncle

I’ve always loved babysitting for my auntie Tammi and uncle Taylor. Although, if I’m going to tell this story properly, I guess I should be precise; we aren’t actually related, not officially. But Tammi’s been my mom’s best friend basically forever, all through middle and high school, roommates at university, maids of honour at each other’s weddings. Our families are closer together than to any of the people we’re actually related to. And I’ve been their go-to babysitter since just after baby Cassie was born (Mom and Dad got started on having kids quite a bit earlier than they did, obviously). Cassie’s an adorable and very rambunctious three now, and she was always thrilled when her big cousin Lizzy came over to take care of her during her parents’ twice-monthly date nights. It had become habit for us to brush our teeth and change into our sleep clothes early, then cuddle up on the couch together watching kids movies until she passed out. I’d carry her to her room and tuck her into bed, then watch some more grown-up movies by myself or play around on the computer until either Tammi and Taylor got home or I was ready for bed myself, at which point I’d go crash in the guest room until morning when they’d drive me home after breakfast.

But about six months ago I discovered an entirely new reason to enjoy babysitting for them. I’d been messing around on the computer after Cassie had gone down, bored out of my mind but not yet tired enough to sleep. The game I’d been playing had been acting kind of slow, and I’d been trying to figure out why—that was when I noticed the huge, hidden folder that was taking up so much space on their hard drive. I new I shouldn’t go peeking… but my curiosity got the better of me, and I opened it up to find tons of video files. Picking one at random, I was shocked to discover a video of my aunt Tammi dressed up in a slutty little schoolgirl outfit, her long, blonde hair done up in bouncy little-girl pigtails, down on her knees and sucking uncle Taylor’s enormous, swollen cock!

I must have forgotten to breathe for a solid thirty seconds, I was so enraptured by what I was seeing! He had to be at least nine inches long, and so thick around, aunt Tammi’s fingers couldn’t even reach her thumbs as she wrapped it in her hands! She was jacking him off at his base as she bobbed up and down on as much as she could fit into her mouth, gagging loudly as it pushed against the entrance to her throat!

I’d never really masturbated before that night. I knew the theory, of course… and I’d tried, a little bit, just to see what all the fuss was about, but I’d been thoroughly underwhelmed by the limited results I’d managed to achieve. But that night, sitting there in the computer chair, watching aunt Tammi obviously enjoying herself so much, her huge, round titties nearly bursting out of her skimpy little outfit, and seeing the look of pure bliss on both their faces… I felt a warmth like I’d never felt before. My hand started moving before I’d even realized what I was doing, reaching up under my oversized sleepshirt, and down inside my panties.

I sighed loudly, trembling, as I began to explore, shocked by the moisture I could feel seeping out to coat my lips. It all felt so much better than when I’d tried before! Uncle Taylor started using his hands, too… one on the back of aunt Tammi’s head, encouraging and controlling her, the other reaching down inside her shirt to squeeze her breast. My shirt had to come off completely then, as I started using my other hand, going back and forth squeezing my titties. Mine were so much smaller than hers, or my mom’s… but it felt incredible, my nipples like firm, fiery little pleasure buttons as I squeezed myself in time with what uncle Taylor was doing to aunt Tammi on the video. I started picturing myself in her place… I even opened my mouth, letting my tongue hang out, imagining how amazing it would feel to have that huge, hard cock plunging between my lips!

Not having any prior experience, it’s no wonder my orgasm came as such a surprise. I nearly fell right out of my chair… and I did give myself a solid whack right on the bone of my shin, as my legs started flailing uncontrollably and I kicked the desk! I managed not to scream and wake up Cassie, thank God, but only just. I sat there in the aftermath in nothing but my cute little pink panties, quietly whimpering and rubbing my shin where it hurt, blinking tears from my eyes. And still… the video kept playing. I bit my lip, knowing I shouldn’t… but I started touching myself again, mewling and twitching at my sensitivity, but I just couldn’t stop myself, not when aunt Tammi was still devouring that enormous, perfect cock! I came again, under a little better control that time… or at least, with a better appreciation of the sensation of welling heat that warned me that it was about to happen, so I was able to push my chair back first and not smack my shin against the desk again. I was maybe half-way to a third, when uncle Taylor got there ahead of me; he pulled away a little, taking over stroking himself, holding the end of his cock about an inch away from aunt Tammi’s luscious red lips, her long, sinuous tongue dancing over them in anticipation. The first jet, impossibly huge and thick looking, shot directly into her waiting mouth. She moaned loudly, clutching and squeezing at her tits through her outfit, as he followed it up with more and more, finally squeezing out the last few drops directly onto her tongue. Only then did she close her lips and swallow, before opening again, wide and proud, displaying her empty mouth. Uncle Taylor praised her as his ‘good little slut’, stroking her cheek with his hand, Tammi purring and nuzzling happily into his touch, before he stepped away to the camera and ended the recording.

I whined in frustration, clawing clumsily at the mouse in my desperation to cum again, backing up to the point of that first, enormous shot of cum bursting into aunt Tammi’s mouth. I paused it there, concentrating on that one frozen moment, and returned frantically to my masturbation. I had my best orgasm yet, imagining that huge, thick load bursting into my mouth, instead of hers! It left me sweating and panting in the chair, my panties absolutely soaked in my juices, not to mention what I’d just done to my fingers! I slowly regained enough control to exit out of the video and put everything back the way I’d found it, picking up my shirt and stumbling into the bathroom for a much-needed shower. It was a good thing I kept some fresh clothes in the dresser in the guest room, that’s for sure! I crawled into bed, exhausted, a little bit damp from the shower, but clean. Or at least, physically clean… after what I’d just seen, and done, my mind was anything but! I rolled onto my side, clutching a pillow to my chest, absentmindedly licking my lips as I ran through it all again and again, a low but stubbornly persistent heat pulsing like a second heart between my thighs as I slowly, fitfully drifted off to sleep.

Needless to say, babysitting hasn’t been the same ever since. And the next time I went over, I was prepared! My special little thumb drive lives inside of a rolled-up sock buried in the toe of an old tennis shoe in my closet, now. It’s a bit paranoid of me, I know… but Mom is way too big a snoop for me to trust leaving any of my pilfered videos on my actual computer! It travels back and forth with me to Tammi and Taylor’s place, as well, since every time I come over it seems like there’s at least one or two new videos to add to my collection.

I was laying in bed in their guest room, eyes closed, hand in my panties, still thinking about their most recent video that I’d just finished watching for the third time that night, before I’d finally closed down the computer and stumbled my way into bed. It had been another in what I thought of as their ‘basement collection’; this one had aunt Tammi tied standing up, starfish-style, with soft red ropes at her wrists and ankles attached to the support pillars down in the unfinished basement, while uncle Taylor had done her hard and fast up her ass from behind! I moaned quietly as I thought about it, about the look of ecstatic pain and pleasure on her face as she took that enormous cock up her sexy, round little butt, until he came deep up inside of her ass! It wasn’t the first anal video I’d seen… but I’d worked my way through watching all their videos by then, and anal was something they only did very occasionally, so it was a special, extra-naughty treat for me to see. It made me feel so hot and dirty, just thinking about it! And especially knowing, since it was a new video, that she’d taken it up the ass like that sometime in just the two last weeks, since the last time I’d been over!

My thoughts were interrupted by the sound of the front door opening and aunt Tammi’s drunken giggling. I smiled briefly, then forced my expression to go slack. Sure enough, not a minute later the door to my room opened slowly, Tammi checking that I was asleep. The door closed again, and I allowed my grin to return. They’d be having sex after date night either way, I’d come to realize over the intervening months, but if they thought I was sound asleep it meant they wouldn’t concern themselves as much with trying to stay quiet while they did it, so I’d be able to hear more while I was listening in.

I didn’t have to wait long, Tammi’s giggles and squeals, punctuated with an occasional loud slap on her ass and the accompanying shriek, telling me they were doing it doggy-style; I knew from their videos that uncle Taylor really enjoyed spanking her in that position, more than in any other. I started playing more intently, my pillow nearby and ready for when I’d need to muffle myself. It was hard not to speed up, especially when I could hear Tammi starting to cum… but I’d already made up my mind that I was going to try stretching it out and denying myself that night, going for one really strong orgasm to coincide with Taylor’s, rather than several weaker ones alongside each of Tammi’s the way I normally did it. I could already feel it building, making me back off until I was just barely teasing my clit, hovering on the edge. Taylor’s final loud grunt, and Tammi’s shrieking, trembling wail as she felt that hot, thick seed bursting up inside of her, pushed me over the edge. I rolled over, burying my face deeply into my pillow, legs trembling as I vibrated my fingertips across my clit beneath me, the pleasure crashing over and through me in wave after wave.

I finally had to stop, unable to take any more. I rolled back over gasping, bringing my fingers to my mouth, smiling as I licked them clean, loving how naughty and dirty it made me feel! I readjusted my panties and pillows, quickly settling down, certain the endorphins I’d just flooded myself with would soon have me drifting off to sleep the way they always did.

But no sooner had I gotten my heartbeat back down to normal than I heard what I could swear was the sound of the tv out in the living room. That couldn’t be right, could it? Not at that time of night. Maybe I’d already fallen asleep after all, and hadn’t even noticed that it was morning now? Cassie was a devious little monkey; it wouldn’t be the first time she’d woken up early and gone out to watch cartoons while she waited for everybody else to wake up. I sighed, but rolled over and forced myself out of bed. If I was going to be the babysitter, it meant that at least occasionally I had to do some actual babysitting. I just hoped I could convince her to go back to bed, so I could do the same.

I stumbled down the hall, yawning and rubbing my eyes, the dull gleam coming from the tv screen confirming that I hadn’t been imagining things, though the volume was low enough now that I could no longer hear it. I stepped around the corner, an annoyed reprimand for the little imp ready on my lips… but what I saw froze me in my tracks.

I sank back around the corner, quiet as a mouse, peering out at my uncle Taylor sitting on the couch. I couldn’t see what he was watching, since the tv was mounted on the same wall I was currently skulking behind, but I could guess; his robe was wide open, his huge, hard cock pointing proudly skyward as he stroked it slowly up and down.

I strangled a moan, my hand instinctively finding its way under my sleepshirt and into my panties. God, he was big! Seeing it on a screen was one thing, but now, in real life… he was using both hands, one above the other, and still he wasn’t covering the whole thing! What I wouldn’t give to be my auntie Tammi in that moment, so I could just go join him and take over…

I don’t know how long I stood there, barely peeking out around the corner. I new I didn’t dare let myself cum, there was no way in hell I could keep quiet if I did! But I was so close already, swallowing reflexively as I salivated at the sight of it, dreaming of taking it into my mouth, of tasting it, my panties already soaked straight through and clinging wetly to my skin.

Then, suddenly, his eyes glanced over, meeting mine, and he jerked in shock. I gasped, wishing I could vanish, or flee, or anything except stand there stupidly with my hand in my panties as he stared at me. He should have yelled, swore… he at least should have covered himself back up under his robe. But he did none of that. And what he absolutely, positively should not have done, was to continue slowly stroking his magnificent cock as he stared directly into my eyes.

“Come here,” he whispered, his voice low and gravelly, trembling with command, and making me tremble in places better left unnamed.

I shook my head slowly, biting my lip, knowing I should back away… but it was already taking every ounce of my control just to stop myself from rushing forward.

“Come here,” he repeated. “You should at least see what I’m watching before you decide if you want to leave.”

I swallowed nervously, took a step. Then another. Before I knew it I was at the side of the couch, gasping at what I saw on the screen.

“You found our videos,” he said, and all I could do was nod in shock, realizing my guess had been wrong after all. He wasn’t watching a video of himself and Tammi… that was me on the screen! I was on the chair in the office like always, my sleepshirt on the floor beside me, my firm little titties fully out on display, my panties down to my knees as I furiously masturbated my pussy.
