Elena sat up with a groan of annoyance. It was Monday, and like most people she hated Mondays. She'd barely seen her son, Jason, all weekend as he was either off with his friends, or in his room playing video games with them online. She sighed and blew a lock of her blonde hair out of her face and chuckled to herself. He was 18 after all, and would be off to college soon, better to let him have his fun before he'd be away at school.
She got out of bed and headed across the hall to the bathroom to take a shower. Just before she turned the water on, her cell phone, which she had left in the living room to charge, started ringing.
"Shit," she mumbled, "Of course just as I'm about to step into the shower."
She grabbed her bathrobe and tried to tie it closed while grabbing the phone. She utterly failed and left the robe hanging open as she saw the call was from her boss. Her boss wouldn't be calling this early if it wasn't important. She sat down in the desk chair as she answered the call.
Jason woke up slowly, and looked over at the clock.
"Seriously?" he mumbled to himself. Despite school being over, and having been up late last night, he still woke up at the same time he would have if it had been a normal school day.
"Well fuck it," he said to himself, "I'm awake now, might as well get something to eat."
He opened the door and stared in shock as he saw his mother sitting at the desk, her bathrobe open and her body exposed to him. Elena for her part was glancing out the window as she listened intently to her boss but looked toward Jason's room when she heard the door open. She saw the look on his face and then looked down and realized her robe was open. She quickly turned away pulling the robe closed with her free hand, and Jason, for his part slammed his door shut, his heart hammering in his chest.
"Holy shit." was all he could think to say.
He knew his mother was good looking, and that she had a killer body (all the women in his family did), but he never thought he'd get to see it. He could feel his dick getting hard as the sight of his mother's perfect tits was burned into his brain, along with the little tuft of blonde hair peeking out from between her legs. He had never thought of his mother sexually, and now he had just seen her naked, even if only for a few seconds. He couldn't help but think about her sexually now.
Elena finished the call and secured the robe around herself. She headed back to the bathroom, and had to pass Jason's room. She stopped outside the door and almost raised her hand to knock before she thought better of it and headed into the bathroom to take her shower. How much of her had her son seen? She wasn't expecting him to be up so early, but maybe he was just used to being up this early and he woke up out of habit? No time to worry about that, she had to get to work.
Jason couldn't keep the image of his mother out of his head, and now he could hear the shower running. The thought of his mother running her hands over her gorgeous body as she washed jumped into his head, and he lay down on his bed as he pulled his cock out and started slowly stroking it replaying the brief moment of nudity over and over in his mind's eye.
Elena finished her shower and got dressed, the moment of Jason catching her all but gone from her head. She fixed her hair and checked her makeup one last time, and figured she'd let Jason know she'd be leaving for work. She opened his door a crack and this time it was her turn to catch him.
"Jason, I'm-"
Jason was lying on the bed, eyes closed, and his cock in hand. As soon as he heard his mother's voice he quickly covered himself and turned on his side facing the wall.
"Jesus mom! Don't you knock?" he yelled in shock.
"S-s-sorry honey," she stammered, closing the door and trying to catch her breath, "I just wanted to let you know I'm leaving for work." she said, raising her voice to be heard through the door.
"Ok, bye." Jason said rather curtly.
Elena paused for another moment, thought better of saying anything else and left. Jason let out a breath he didn't realize he was holding as he heard the apartment door close and lock. Well, that killed the mood. He tucked his now limp dick away and got out of bed. After grabbing something to eat he called a couple of his friends to see if they wanted to hang out, and then hopped into the shower.
Despite his mother interrupting his masturbation a few minutes earlier, he again found himself thinking about catching her naked, and then her catching him, and wondered exactly how much she saw before closing the door. His dick got hard again as he also thought, for the first time, that she was naked in this very same spot a few minutes ago. Running her hands over her body. However the image in his mind wasn't of her washing up, but feeling herself up, running her hands over her tits, down across her stomach, and between her legs. He grabbed his cock and started masturbating again, as the image of his mother started masturbating as well. In a matter of minutes, Jason felt his orgasm approaching and groaned in pleasure as he fired several loads of cum against the shower wall.
"Fuck," he mumbled, "Did I just jack off thinking about my mother? What the fuck is wrong with me?"
He tried to put the thought to the back of his mind and washed up so he could go hang out with his buddies.
At work, Elena was distracted, the image of Jason masturbating burned into her mind. The sight of his hard cock in his hand as he stroked it (thinking about her?) wouldn't leave her mind for more than a couple of minutes at a time.
"Elena?" one of her coworkers asked, "You okay?"
"Yeah, why?" Elena asked, quickly regaining her composure.
"Because you've been staring off into space for the last couple of minutes."
