Author's Note: All characters depicted in this story are above 18 years of age, and are purely fictional. Furthermore, this is my first submission, and while this is conceivably part of a series, I currently am not sure how many chapters it will have or where it will go. It has some back story but in general I would categorize it as fast-paced.

Eric stretched his arms and leaned toward the small airplane window to his right. The flight attendant's safety routine was a faint hum in the back of his consciousness. Eight hours on a plane, he thought. It would be a miracle if he was alive when they got there. Of course, there were things around to occupy his attention. He turned his head back to the left and met eyes with his sister, Kim. As the flight attendant was saying that smoking in the bathrooms was illegal, that familiar smirk he had grown to appreciate in recent weeks crossed her face, and he couldn't help but grin.
Kim was 18, a year younger than his 19, and was quite a looker. He hadn't always been aware of it, but like that smirk of hers, many of her attributes had grown on him over the preceding month, and he found himself casually admiring her petite, 5'2" frame, flaxen blond hair and athletic build. Her tanned legs were pulled up to her chest, pressing her perky B-cup breasts together. She used to be a gymnast, and while her interests had changed in high-school, her flexibility remained excellent, as he had witnessed. He was looking at her glossed lips when they began to move.
"At least it's first class," she commented.
He nodded, never the type to engage in small talk. First class was a bonus, but there were complications. His parents, seated in the row in front of them, were very gracious to have provided the tickets, and the accommodations at the lavish hotel in Florence they were headed to. His father Dave, inheritor of a sizable family wealth, was never parsimonious with his assets; unfortunately that same generosity had led to the presence of the woman seated across the row from Kim.
Nadia was his mother's younger sister, and at 34 years of age he had to admit she was quite stunning. Like his mother, Katerina, she was Czech, and like his mother she had black hair, an olive complexion, dangerously high cheekbones and dazzling blue eyes. She also was quite curvy, as the stranger sitting next to her was finding out by a few not-so-casual glimpses down her blouse. Eric had to guess her tits were at least 36D, but obviously couldn't come up with a reasonable way to verify his suspicions.
Yes, she was pretty, he thought, but why did she have to be here now? This trip had been planned almost a year in advance, and with the hotels crammed full, Nadia had been invited along, now meant to share the two-bed hotel room with Eric and his sister. His sister wasn't happy when she heard either--more so because she knew it meant sharing a bed. Eric would have been fine with the development if it hadn't been for the events that unfolded earlier this summer.
The plane started down the runway, and he relaxed as he felt his body pushed into the squishy seat. This is going to be tricky, he thought.

Eric woke from a doze, momentarily forgetting he was on a plane. He peeked out the window and saw it was still dark outside. This red-eye business was no joke. He grunted uncomfortably as he felt his cock strain against his shorts, rigid from the nap, a frequent problem for him; his 9" cock was difficult to manage or hide in pants at full mast. His thoughtful sister had gotten a blanket, though, so at least he didn't have to worry about showing too much in public.
He inspected his reflection in the window from the dull cabin lights and rubbed his jawline, his stubble showing under his slightly-shaggy brown hair. He had gotten some of his mother's ethnic features, and was quite handsome-- his brown eyes sucked girls in and he knew it. He had already had a few victims his first year in college, though none of them lasted. Maybe they just couldn't handle this, he thought with a chuckle, absently rubbing his still-hard shaft. He had a 6'0 frame, slim but muscular thanks to a healthy combination of running and weights.
He had closed his eyes again when he felt a slight pressure on his dick. Looks like his sister was up as well. Her eyes were still closed, but under the blanket covering them both, her hand was riding his shorts up his leg and then gripping his monster shaft right under the head. She began to gently jerk him off, eyes still closed, but a smile playing across her lips. Eric began to return the favor, reaching his hand over to her seat where her legs were still bunched up, sliding it in between her warm thighs to rub on her crotch through her skimpy jean shorts.
Until several weeks ago, this kind of behavior would have been unfathomable, but it had now become almost commonplace, and his sister leaned over to his ear and whispered, "I'm going to go to the bathroom."
Eric waited a couple minutes after she had left, then tucked his still-throbbing cock up under his belt and made his way to the "occupied" restroom. He rapped his knuckles against the door like he said he would, and quickly the door opened and he entered casually without being noticed. His sister was sitting on the little sink, still dressed but legs spread wide and inviting.
"So how long did you wait before getting up to your old tricks again? Two hours?" Eric asked playfully as they both fiddled with the buttons on his cargo shorts.
"Oh, shut up," Kim retorted, "you know this week is going to be frustrating, and once the plane lands I don't know how long it's going to be till we can get our hands on each other again." With that, she pursed her lips and spit heavily on the end of his cock, both her hands wrapped around its considerable girth, and smeared the saliva up and down until his prick was proudly glistening. "What with Auntie-Big-Boobs mucking up the works," she griped, then let another glob of spit trail from her tongue down to his dick, expertly aimed from two feet above. Eric was always amazed at how much spit she could produce.
"What, you jealous of her tits?" Eric quipped, one hand sliding aside her jean shorts while the other played with her shaven pussy.
"Oh, that's right," she said with a sarcastic grin, "I just wish I had those big melons that nearly make me fall over and make every creep in a hundred feet hang their tongue out of their mouth." Her breathing became heavier as Eric slipped his index finger up her pussy, his thumb playing with her clit. She slid off the sink counter down to the floor, saying, "You can do me when we get back to our seats, I need to take care of this before someone actually needs to piss."
His cock looked massive next to her pretty face, and Eric groaned as his sister opened her mouth wide and took in about half its length. She began ardently moving back and forth, sucking his cock deeper until it was in her throat. He could see her left hand fingering herself below while her right worked the spit covered shaft in front of her lips. She was staring right into his eyes as she took all but an inch of him into her throat, her throat muscles gripping his shaft while her blond hair dangled around his hips.
