The Perks of Babysitting Mf, Mfff, inc, oral, anal Summary: A man gets more than he bargained for when he finds himself babysitting his teenage step-sister and her friends for a week. ---- If you learn anything from my story, it's that never underestimate the deviousness of spoiled teenage girls. Oh, I know what you're thinking. You're thinking that your years of worldly experience and maturity make you immune to the manipulations of girls not even old enough to vote. You think that you can maintain your composure even when faced with a creature who is used to getting exactly what she wants and knows new ways of getting it. You may be right. I certainly thought I was capable of managing my stepsister and her two fifteen year old friends for a week while our families were on a second-honeymoon in Aruba. I didn't think anything could go wrong; I thought I could weather whatever whining, tantrums, and cajoling they threw at me. Needless to say, I was mistaken. ____ I was twenty-seven years old when it all began, fresh out of an MBA program at a good school and comfortably enjoying my six figure salary. I had moved out of my parents' house a few years back, settling a few miles away in a new suburban development. I wasn't exactly living in a palace by any means, but it was enough for me and my girlfriend when I bought it. Three bedrooms, two baths, a rec-room downstairs in the basement, and, of course, a pool in the backyard. Served me well up until my girlfriend left me and I was left with too much house to handle. The last feature had made me very popular with my family and our close family friends, the Derricks and the Hendersons. My stepsister, Amy, had been friends with Cassidy Henderson and Ashley Derrick since the three of them were in diapers, and naturally our families were close as well. We took trips together, went to dinner together, and, of course, came over each other's houses damn near every day. And in the summer, more often than not that meant invading my backyard and barbecuing while the girls used my pool. I should probably introduce the little monstrosities before we go any further. My stepsister Amy was unquestionably the leader of the bunch. At fifteen years old, she was five feet, four inches of freckled blonde firecrackers. Curly hair usually perched on the back of her head in a ponytail, and glittering green eyes usually flickered with some diabolical scheme to swindle mall money out of my parents. She was every high-school freshman's dream girl, long toned legs, a tight little ass, and perky breasts that stood out from her chest even when she wasn't wearing a bra. I had more than my fair share of un-stepbrotherly thoughts about her, and I'd be lying if I said I didn't move out to get away from her before I did anything rash. Amy had a nasty habit of walking around the house in only panties and a thin tank top when my mom and her dad were out at work, taking almost every opportunity to bend over in front of me, lean forward so I could see down her shirt, or remind me of a childish crush she had on me before I went to college. I couldn't tell if she was doing it on purpose; I just knew I was going to be in trouble if I had to share a bathroom with her for very much longer. Cassidy Henderson was unquestionably the sweetest of the bunch, an altar-girl at our church and member of the school's 4h Club. At five-eight, she had developed earlier and fuller than her friends, filling out a petite hourglass figure. Her long red hair hung braided down to her firm little ass frequently covered in tight-cut off shorts. Her blue eyes were her deadliest weapon, capable of unleashing Puppy Dog Eyes that could melt the stoniest of hearts. She was also the most physical, frequently surprising me with tight hugs from behind every time she saw me. Cassidy drew the eye of every man I knew, myself included. Unlike my thoughts about Amy, I had no such guilt fantasizing about her pretty blue eyes looking up at me while her puffy pink lips were wrapped around my cock. Finally, there was Ashley Derrick, a brunette whose tantrums were legendary. At five-two, she was the shortest of the bunch, but made up for it with more spunk than Amy and Cassidy combined. She wore her dark hair short, and with a splash of blue across the bangs. Her tits weren't anything to write home about, but her ass and legs were far and away the nicest of the three. Pert, plump, and just enough jiggle to bounce when she ran, Ashley turned heads when she competed in track, and not because of her mile time. She was definitely the brattiest of the bunch, shouting down her parents into paying for her nose stud, her hair dye, and a brand new Gibson Les Paul when she took up guitar. She was also the most aggressively sexual, not even bothering to hide the fact that she'd lusted after me ever since I got home from school. It seemed she was always making excuses to brush up against me, slap me on the ass when no one was looking, or crawl into my lap when I was watching TV. Needless to say, I tried not to be alone with her for too long; out of more fear of what she would do than what I would do. Unfortunately, I wasn't going to have much of a choice in the matter as summer approached... ______ "It'll only be for a week, Mikey," my mother insisted, counting out a series of bills and handing them to me as she lingered in the doorway. "You act like this is the first time you've babysat them." "I babysat them when they were little," I reminded her, taking the wad of bills and stuffing them in my back pocket with a resigned sigh. "They're..." "I know they can be a handful," Mom clucked, patting my arm. "But it won't be for long and you work during the day anyway!" "I guess," I sighed. As a business consultant, I mostly got paid to appear in the office and make senior management feel good about the way they ran the company. I got paid a hefty fee to spout off words like "new-synergy" and "vertical mobile paradigms" and then correspond via e-mail until they needed me to come in again. Soulless work as it was, it paid very well, so I didn't complain much. "Just drop them off at the mall if you don't want to hassle with them then," Mom said, as the Derricks' car pulled into my driveway. "I guarantee they're going to spend most of the day lounging around the pool anyway, so it isn't as though you're going to have to entertain them." "I guess," I sighed, rubbing my neck as my charges for the week stepped out of Sue Derricks' minivan. Amy hopped out first, toting a duffle bag and wearing a tube-top and short-short combination that made a passing mailman stop and stare for a brief moment. Following her was Cassidy, balancing a floppy sunhat on her head while trying to keep the hem of her thin yellow sundress from blowing up in the wind. Finally, Ashley jumped out, dressed in only a pair of bikini bottoms and a faded, sleeveless rock-tee. I shot a warning glare at the mailman who had looped back, sending him scurrying off as the girls passed me in the doorway. "Thanks for putting us up, bro," Amy said, lightly bumping into my shoulder as she passed. "Beats staying with the grandparents for a week, that's for sure," Cassidy giggled, looping her arms around my neck in a hug tight enough that I could feel the contour of her bikini covered breasts through the sundress. "We promise not to trash the place too badly," Ashley laughed, bumping her hip into mine with a small wink that my mother failed to pick up on. "You have our numbers if you need anything," Mom said, shouldering her own duffel bag as Sue honked from the driveway. "Remember; firm hand. Let them know who's boss." "Because you and Mark have been so good at that, right?" I muttered. "What?" "Go before you and Dad miss your flight," I said, hoping that my mother didn't hear anything. She looked suspicious for a moment, but the lure of Aruba pulled her away with a small wave. I stood out on the porch for a moment, watching her go with a smile that dropped the moment Sue's car rounded the corner and left my neighborhood. Behind me were three of the most unruly teenage girls I had ever encountered; my charges for a full seven days and six nights. As unruly as they were, I wasn't about to let my stepsister and her friends walk all over me; I had to be firm, otherwise I would be picking up after them all week. "Alright, ladies," I said, turning back into the house. "Let's get a few ground rules out of the wa-" My carefully planned out list of rules and courtesies seemed to go out the window as I returned to find all three girls stripping in my living room. Stripping may be a harsh way to put it, since they had their swimsuits on underneath, but I was still confronted with the sight of my stepsister and her friends tugging their t-shirts and dresses over the tops of their heads, throwing them on the couch as they undid their bottoms while they chatted. Even Ashley stripped off her modest bikini bottom, revealing a scanty black thong-bikini that would have been right at home on the beaches of Rio. Amy wore a slightly more modest tube-top, but her bottoms left almost nothing to the imagination, exposing her firm, freckled cheeks to the cool living room air. Thankfully, Cassidy was wearing a more modest floral one piece, otherwise I may have very well ripped a hole through the front of my pants. Amy noticed me standing there as she tied her hair up into a curly ponytail. "Hey can you take our stuff up to our rooms, please? We wanted to get a swim in before it got too late." "I...hey, wait a minute!" I called after the girls as they charged towards the back door. "Thanks," Ashley said, turning around with a small wink. "We owe you one." I watched her go, thong hugging her tight teen ass as she skipped out the back door and joined her friends splashing and laughing in the pool. I blinked, letting out a deep sigh as I began to gather their discarded clothes and baggage. Ten minutes into our time together and I already knew it was going to be a long week.
