Anson turned the knob slightly and frowned at the locked door. He could see a dark shape through the heavy frosted glass.
Professor Ingersol had given him an assignment that would be his last chance to pass the adult writing course he was taking to earn the credit needed to graduate that year. Failing would mean another full year of high school and enduring is parent's relentless badgering. If he hadn't fucked around all year he wouldn't be in this mess and now he was about to screw up this up.
He didn't even know this course was available until his guidance counselor had recommended it. It wasn't open to just everyone and each student had undergo a gruesome interview with the instructor. The class was called Enlightened Adult Writing and didn't sound remotely interesting until he arrived the first day for orientation.
The class was restricted to students at least eighteen years old and consisted of six women and one undecided, the latter sitting in the back to his/herself and never looking at or speaking to anyone else. Professor Ingersol was sixtyish with white hair and black round glasses that gave him the appearance of a wise owl. He smiled rarely and had a deep baritone voice that reverberated off the walls of the small classroom. He announced that the class was dedicated to erotic writing only and that each week a paper was due on whatever subject aroused the author's passions. Those passions were to be put on paper and shared with the class orally, after which suggestions and opinions would be openly shared. Grades on each would be by unanimous consent and so far Anson had failed to empress his fellow bards. With the term ending in only a few weeks Ingersol had given him one reprieve. Anson was to write a story so erotic that it would cause the Professor to get an erection. No erection, no passing grade.
He had worked all night for a week writing the most erotic story he could think of and now was the time to present it. Ingersol had told him to come by his office at 1:30 the following Saturday to present it and receive his final grade.
He pecked lightly on the glass and after waiting for a response, wrapped harder until he saw the shape rise from the desk and walk to the door.
Professor Ingersol was dressed in his customary blue blazer and khaki pants but today his blue button down was open collared and the light scent of his Stetson after shave drifted out the door as he looked at Anson, who had worn his school blazer and tie.
"Right on time. Good!" Ingersol said and opened the door wider. Anson walked in thanking him and jerked back around when the older man closed and locked the door behind him.
"Let's see what you came up with."
Anson placed his backpack on the edge of the large desk and unzipped the flap. "I hope this is up to your standards, sir." he said handing the bound paper to his teacher.
"We'll see." Ingersol replied and gestured to a chair across from his desk.
Anson retrieved his backpack and placed it on the floor beside the chair and waited for the Professor to sit. Ingersol leaned back and opened the folder and began to read:
One Weird Morning
by Anson Weatherby
Glen opened the bathroom door and gasped. His sister Kristy was standing naked at the bathroom vanity applying eye makeup in the mirror. He looked at the reflection of her and stared at her petite breasts with cherry red nipples poking straight out in the sudden chill of the open door. Below, at sink level was the blond pubic hair, above which, obscured a magic place he'd thought about so many times.
He said "Sorry!" and awkwardly started to back out, closing the door.
"My fault, bro. I lost track of time," she said and indifferently began putting her make-up back in the open drawer then shutting it. She slowly reached for her towel and somewhat made a show of draping it around her as though he couldn't have seen her nudity seconds before.
She sashayed across the tile floor towards her bedroom door on the opposite side of the bathroom they shared. Glen watched and she walked into her room and closed the door behind her. His morning wood was now elevated to a complete erection straining the front of his plaid boxer shorts and he cursed to himself as he stripped them off, dropping them into the hamper on this way to the toilet. He awkwardly bent over the bowl bracing himself against the wall with his right arm while bending his penis as far down as he could until at last the relieving stream of piss came.
He flushed, opened the shower door and turned on the water adjusting until it suited him. He stepped in under the steaming water and shampooed and rinsed his hair, then grabbed the soap and began to lather his arms and chest working his way down to the erection still sticking straight up.
'Weird,' he thought as he began stroking himself. This wasn't the first time he'd walked in on Kristy, who had just turned eighteen six months after he had. If fact for the last couple of weeks there had been at least four times he had walked in through the unlocked door on her while she was naked. They had always had a standing schedule for the bathroom in the mornings and she had always been finished and gone by the time his turn came. The first time it happened she had grabbed a towel and covered herself before he could see anything, but each time since she acted less alarmed. It was almost as though she were waiting for him to see her.
He stroked faster as her wondered if she was purposely waiting for him to see her naked. Why? They had never shown the least interest in each other sexually (although he had to admit to himself he sometimes pictured her while jerking off ). Did she maybe fantasize about him too? Why not? He worked out and was on the swim team and they were both attractive with blond hair and brown eyes.
He squeezed himself harder, cupping his balls as he replayed the morning in his mind, this time instead of backing out, he walked up and put his arms around her, cupping those perky tits in his hands. He pinched her hard nipples with his thumbs and forefingers making her moan while he nuzzled her neck with his nose, smelling the freshly applied perfume behind her ears.
She reached around and slid her hands down his slim waist, sliding her fingers inside the elastic of his boxers pushing them down, causing his rock-hard dick to spring up against her ass and he began rubbing against her, sliding it up and down her crack. She leaned forward on the vanity, her long blond hair spilling down along the sides of her face as Glen slid his left hand down her tight stomach across her rib cage and over her pelvis running his fingers through the curly triangle of hair. He alternated kneading her breasts with his right hand while he probed the warm slit with his left, gently running his forefinger back and forth and when she whimpered, he slowly inserted his first two fingers probing lightly until she pushed her ass harder against his cock and then he inserted the third. Her warm, wet pussy acted like a vacuum, sucking his fingers deeper inside her.
Glen pinched her right nipple hard and when she breathed deeply at the sudden pain, he pushed his fingers inside her as far as he could. Kristy bowed her back in pushing her ass out. Glen felt the tip of his dick with his pinky and guided it inside her retracting his fingers. He grabbed her hips with both hands and pushed in as far as he could. Kristy spread her legs wider as he entered her and she jerked her head, flinging her hair over her right shoulder. She looked at Glen's reflection in the mirror and said, "Fuck me hard, bro."
He slid his hands up her back and spread his fingers over her thin shoulders. He adjusted his stance by shifting his feet while pulling back, then pushed in again repeatedly until he gathered a steady momentum. He watched his sister's face in the mirror as she closed her eyes and opened her mouth in a sign of ecstacy. After a few minutes of steady rocking fucking Kristy lifted her left hand from her grip on the vanity and placed it against the mirror. She reached around and grabbed Glen's ass with her right hand, squeezing tight and then slid her fingers over and down his sweaty crack until felt his balls. She fingered his hairy, tight sack and he could feel her becoming wetter, hotter as he fucked faster, watching in the mirror as her tits jerked with every thrust.
