Alex was a reclusive girl. She was never very interested in seeking relationships with those around her. She only had a couple friends who were very close; they could both vouch for her shyness. She was awfully cute, with soft, short, golden brown hair that fell to her jaw line and eased a little on the boyish side.
In fact, her entire being was a bit on the boyish side, but her face was still pretty with large, green eyes and a nice, albeit somewhat awkward smile that she rarely displayed. She had a small nose and a sprinkling of freckles across her cheeks. She was about 5' 10" and lanky, sporting a petite frame. Her pert b cup breasts were somewhat on the small size compared to the other girls at school, but she felt this was a good thing. If they were larger she'd have one more reason for people to look at her, but her tight, toned ass wasn't helping at all. Years of running cross country had honed her body to nothing but muscle that hugged tight to her bones.
She was strong in body and mind, but not strong in will. While she enjoyed being in shape, she disliked the attention it brought her. Thankfully she wouldn't have to put up with it for too much longer, seeing as she was set to graduate college at the end of the year.
Kate was Alex's younger sister who was just about to graduate high school, being about 4 years younger than her sister. Kate had bright blonde hair that fell to her shoulders. She was a bit shorter than her sister, standing at 5' 2", and she was a tad bit stockier, but her breasts were much larger: almost d cups.
Where Alex was pretty and attractive, Kate was riveting and lust inducing. Her face was slender and elegant with a beautiful mouth often stretched in a playful smile. Her icy blue eyes radiated hunger and want, while also showing confidence, and sometimes defiance. Her smooth, silky skin was free from blemishes and her gait was infused with the perfect sway of the hips.
She never, however, dressed skimpily, which went unnoticed by everyone who were instead distracted by her radiated sex appeal. She was the subject of almost every boy's wet dream, but she wasn't slutty... at least not too much...
Alex was still a virgin and she was just fine with staying one, for a little while longer at any rate. She wasn't interested in sex because she wanted to be completely focused on her studies. Biochemical engineering takes quite a bit of studying to excel at.
Though that isn't to say she was completely inexperienced. She had on many occasions masturbated in the safety of her dorm room. Thankfully, she was the only one residing in her room, so she wouldn't have a roommate who would accidentally walk in on her rubbing her pussy before a computer monitor.
Kate was quite experienced in the field of sex. She was a bisexual and had felt both the strong hands of a man and the gentle caress of a woman, sometimes at the same time. She loved sex, but did not often love people. She had never had a boyfriend (or girlfriend) last for a large length of time. This was not for lack of trying, however; she has just never found the right person who could balance the needs of the mind with the needs of the heart.
Kate had joined the LGBT club at her school in freshmen year. She had at first been looking for a place to see the social interactions between the homosexual and bisexual subculture. But as she got more and more curious about her own sexuality, it became a sort of hub for her experiments. She had seduced quite a few members of the group to help her feel pleasure from both ends of the spectrum, and she loved every minute of it.
It was winter vacation and both sisters were off of school for the next couple weeks. Alex returned home from Minnesota to the obvious sounds of sex resonating from her sister's room. Their parents were out buying groceries, but had promised they'd be home not long after Alex arrived. The moans and groans of lustful contact were loud and clear, echoing down the halls and stairs to the foyer.
Alex sighed, dropped her keys back into her pocket, and proceeded to walk back through the front door, locking it behind her. She then rang the doorbell and waited for a response. A few agonizing minutes later, Kate arrived at the door, somewhat frazzled and flushed.
It seemed she had quickly thrown on a pair of pajamas. Bright smiles were met as the siblings embraced, but Alex could not help notice her sister's nipples poking her through the thin fabric of the shirt. She could also recognize the smell of sweet pussy juice rising up to meet her, and she had to fight the urge to look down and see whether or not her sister's panties showed signs of dampness. She also heard, very slightly, the sound of the back door opening and closing. She sighed again at the crazy love life of her sister.
This whole encounter, however, was beginning to make her somewhat aroused and she could not fight back the feeling that she wished she could swap places with her sister at the moment. She didn't often feel these powerful surges of want and lust, but when she did they were enough to make her fantasize about almost anything.
They broke their hug and they exchanged greetings, "Hi! How's school?"
Alex replied, "It's just as exciting as ever, though I'm sure not many people would find growing tissues in a petri dish very exciting."
Kate chuckled at her sister's modesty. She had been very impressed with her ambition for quite some time and had looked up to her as an idol.
"I didn't wake you up, did I?" asked Alex, trying to sell the idea that she had no idea what her sister had been doing only moments before. Kate quickly realized her bedraggled appearance was somewhat suspicious for it being noon, but she went along with it, forcing a fake yawn and saying, "Yeah, I wasn't expecting you home so soon, or I would have woken up and at least gotten dressed."
They both giggled nervously before Kate said, "If you'll excuse me, I'm gonna go take a shower and freshen up a bit. Just make yourself at home!" She winked and with a quick dash up the stairs she was out of sight.
Alex slowly made her way into the kitchen, helping herself to an apple from the fridge. She was starving from her long drive. She resolved to wait to unpack her things until her parents returned. She walked into the living room and removed her shoes, neatly standing them next to the couch. She sat down and grabbed the remote, flicking on the television.
Kate sighed as she heard the TV come on and she knew now she could finish in peace. She made her way into the bathroom, stopping along the way to grab her favorite toy: a dual ended strap-on. She turned on the water and as she waited for it to get warm she quickly stripped down. She poised the strap-on head at her pussy and pushed eagerly.
The entire length of the one side slid up with ease as her pussy had been stretched just moments before with her latest male fling. She loved this toy the best because as she moved the shaft in and out of her dripping wet hole, she would pretend she was a guy and was beating off her pretend cock with the other end.
She stepped into the now-hot shower and continued thrusting with her right hand. Her left hand roamed from tweaking her short brown nipples, to flicking her erect clit, to massaging her soft ass cheeks. Eventually, she reached between and began rimming her tight asshole with her index finger. She moaned with ecstasy, loud and confident she would not be heard due to the running water. But a small doubt crept into her mind. What if Alex had heard? What if she came up to see what was going on? What would she do when she saw her sister, masturbation shamelessly?
