John was a forty-year-old partner in the largest law firm in town, with three hundred attorneys and twice that many paralegals, secretaries, and IT staff. He was attractive enough to have almost any female he wanted and over the years a few had tried. John always deferred.
It wasn't entirely due to his undying love for his wife, Julie. They were in love once, fifteen years ago, but now they made good partners. Julie, a college history professor with a PhD, saw her husband's indifference as an opportunity to take advantage of any number of cute college guys. She had fucked a few who wanted, or needed, passing grades. She had fucked a few who simply enjoyed sex as much as her and took pride in seducing a cute middle-aged professor.
They had no children of their own. But they had the twins, Jason and Emma, their nephew and niece.
No two twins were ever less identical than Jason and Emma. Jason was an introvert, happy to be alone reading a book. Emma was uninhibited, attention-seeking, and artistic. Having just turned eighteen, the twins were preparing for college. But first, their parents--both physicians--were leaving on an overseas vacation and dropped the kids off at Uncle John and Aunt Julie's house.
This was never a problem for the twins as they lived in a big house and were being sent to a mansion. The kids were used to luxury and, while this was neither here nor there for Jason, Emma thrived in this environment.
John and Julie knew Emma would succeed in whatever she did. The high school prom queen and cheerleader captain had the looks, body, and brains to do anything she wanted. John quickly found out just how true that was.
Julie and Jason were out of the house on an excursion that interested neither John nor Emma. John was going to work in his home office most of the day, so it was he and Emma holding fort. John was beginning to believe it was going to be easy having the kids around as he had not heard a peep out of Emma for the longest time. Eventually, he made his way down the hallway to his luxurious office.
John took two steps inside the office door and stopped. Emma stood by his desk, her body speckled with Post-It Notes of various shapes and sizes. She was very obviously naked otherwise. John shut the door and faced Emma again. Looking more closely, he could see that the notes roughly took the shape of a bikini, but with far less material.
"What are you doing, Emma?" he asked.
"This is modern art, Uncle John," she replied with a grin. "Actually, it's modern erotic art. I think it might be what I major in."
"It's...um...different," he said, striding toward her. "But not something a niece should be showing her uncle."
"I didn't do it to seduce you, Uncle John. I have a business proposition for you," Emma said. "I want you to be my agent."
"Why do you need an agent?"
"I'm going to make a fortune from stuff like this. For instance, I'd have someone take a picture of me like this. It will go viral. Then I'd sell the individual notes."
Once John got close enough, he saw that a few notes had writing on them.
"Like this one says 'ELT'," Emma said. "Emma's Left Tit."
John watched as Emma peeled off the large square note covering her left nipple.
"I'll bet you anything someone would pay five hundred bucks for this note," she smiled.
John's eyes raced back and forth from Emma's face to the hard, pink nipple just exposed. Only three smaller notes covered the rest of her full, firm breast.
"Imagine what I could get for this one," Emma said, slowly peeling off the one between her legs with 'EP' on it.
She moved forward until they were almost touching. Emma reached out and put her hand on John's crotch.
"I thought so," she told him. "You think this will work, too."
Emma rubbed her hand up and down her uncle's thickening cock.
"Go ahead, Uncle John. Lick my tit."
When he didn't move, she put a hand behind his head and guided it down to her tit. John reluctantly slid his tongue across the nipple. Emma peeled off another note. John countered by putting as much of the tit as possible into his mouth, sucking on it while Emma stroked his cock through his pants.
John moved one of his hands around to Emma's luscious ass, feeling a few notes barely covering her soft cheeks. He moved back a step when he felt Emma opening his pants. He studied the notes for a second, noticing how she used tiny round notes to represent the strings on her make-believe bikini. But his mind was back on Emma again when she pulled out his nearly full erection.
Emma ran her fingers along it before kneeling. John watched her lick him from his balls up to the tip, and then open her mouth. She lowered her head onto his throbbing cock and closed her lips tightly. Emma began a blowjob that John neither expected nor asked for but was never going to interrupt now.
John gazed at her incredible body and the thick, perfectly styled hair that hid most of her face. Emma was probably right, John thought silently. People might pay a fortune for anything associated with this dream girl.
Emma used one hand to stroke the bottom of John's cock while frantically sucking on the rest. He imagined this was not her first blowjob. But he was damn glad it was her first time with him.
Emma clearly had no intention of stopping, so John prepared himself for the fact his niece was about to make him cum. He put his hand behind her head and pulled her closer, ramming his cock into her mouth with ever-increasing force. She tasted his precum and sucked harder.
John saw a couple of notes fall to the floor. Emma's flawless body was all but there for his viewing pleasure. His cock pulsed until it ached. John fucked Emma's mouth with abandon, caring little whether it was right or wrong.
"Oh God, Emma. Yes. Yes! Now!"
A stream of cum hit the back of her throat. Then another. John's grunts echoed in the office as he came again, cum beginning to leak out the side of her mouth onto her chin. John thought he would never stop cumming as Emma wrapped her lips even tighter around him. He groaned loudly with his final orgasm and Emma looked up with a huge smile on her face, along with some cum.
She looked down at a note with a drop of cum on it. "We could make a mint," she sighed.

As a college professor, Julie was used to being around kids of Jason's age. She found them to be fun, energetic, and occasionally stimulating. Though she had never had sex with a student, there were plenty she often thought of in that way. Jason would have been one of them.
It wasn't as if some of her students wouldn't have consented. Julie and John were both very fit 40-year-olds who jogged regularly and ran in 5K races. Julie was cute, though not supermodel gorgeous. She kept in shape and her body showed it.
Jason's first chance to see it up close was a Saturday afternoon when John had to work at the law firm's offices and Emma was shopping. Julie saw Jason get into the hot tub in the Florida room and she hastily changed into her favorite two-piece bathing suit.
Jason watched as his aunt stepped into the tub across from him, settling down into the bubbling water with a smile. They chatted for a while with Julie learning very little about Jason she didn't already know. No, he didn't know what to major in at school. No, he wasn't dating. Yes, he had dated before.
