It had been a long week. After several days of working at the office past 8:00 pm, Julia Winger thought she deserved some rest and relaxation. A warm soak in the bath and some wine would do for starters, she thought idly as she pulled into the garage. And maybe some intimate time with her battery-powered friend. After all, David had been out of town on a business trip for the past week, and their son, Nick, was out with friends. She could use a little release, and she had the house to herself.
Julia let herself into the house, and humming contentedly, walked into the kitchen and dumped her handbag on the bench. It was only then that she heard the soft moaning and grunting coming from the living room. What was that, she wondered suspiciously, and quietly crept up to the living room door and peered in. She was not prepared for what she saw.
Nick stood shirtless, pants unzipped and sagging, as a slim girl knelt before him, her head bobbing energetically. He had one hand entangled in the girl's long brown hair, with the other clinging to the couch headrest for support. As Julia stared, shocked, he suddenly pulled his dick out of the girl's mouth and, with a hoarse grunt, blasted his cum all over her face.
"NIIICK!!" the girl squealed, springing backwards, and Julia suddenly recognised her as Amber, the daughter of the neighbours three doors down. "I've told you I don't like that!" Amber was clearly pissed off, frantically trying to get cum off her face and out of her hair, and Nick made the mistake of laughing.
"It's not funny," she snapped, grabbing the tablecloth off the coffee table and using it to clean her face. "I've told you before I hate it when you cum on my face, and I'm sick of it."
Realising he'd gone too far, Nick attempted a conciliatory tone. "I'm sorry, Amber," he tried. "I couldn't help it. There's just something about cumming on a girl's face that turns me on. It's so hot."
"Well, I hate it, and I'm done putting up with it," Amber said, and Julia heard the steel in the girl's voice. "We're done. Don't try to call me." She stormed out, and Julia barely managed to dart out of the way and avoid being seen.
"Amber!" Nick called, but he heard the door slam and knew she was gone. He hung his head dejectedly. It had taken weeks for him to build up a friends-with-benefits relationship with Amber, and now it was all gone. He knew it would end eventually, but he'd hoped that they'd at least last the rest of the summer. Now he had over two months until university started back up again, and no guarantee of getting laid during that time.
He didn't think it could get any worse. And then his mum walked in.
While Nick had been bemoaning how he'd ruined his relationship with Amber, Julia was busy thinking herself. She understood completely why Amber stormed out, and was actually annoyed at Nick herself for how he treated the girl. She had raised him better than that. But at the same time, Julia did understand how Nick felt too. As much as she loved David, he was very vanilla in the bedroom, favouring missionary position and only mixing it on special occasions (and typically only upon repeated request). Julia, on the other hand, was a bit wilder sexually, and before she met David she'd loved to experiment in the bedroom, the dirtier the better.
So Julia was torn. Ultimately, she decided to have a serious talk with Nick about sexual etiquette, and figuring sooner was better than later, walked into the living room to confront him. She was not expecting his pants to still be halfway down his knees with his dick hanging out.
Mother and son froze, staring at each other. Inadvertently, Julia's eyes dropped downwards, and she found herself momentarily transfixed by the sight of her son's penis. It was still slick with saliva, and although it had softened, it still looked a respectable five inches long and deliciously thick. Julia unconsciously licked her lips, and although she tried to suppress it, she couldn't help but wonder how big it would be hard. As mortified as he was to be caught post-blowjob by his mother, Nick couldn't help but notice where her gaze fell before he managed to recover and shield his crotch with his hands.
"Mum!" Nick exclaimed, stumbling backwards. "What are you doing here?"
