With a slam of the car door, 18 year old Scott arrived home, having been working away for a few weeks in a remote area, and happy to be home. He saw his Mum's car was there, and he was glad as he'd missed her. He picked up the mail, checking for his name, but it was all for Natalie, his Mum. It was a big house, with the bedrooms on the second floor, and he grabbed his bag and headed for his room. He climbed the stair and entered the hall on the first floor, left the mail for Natalie, then made his way up the next stair to his room.
At the top, he heard a moaning sound, and he quietly moved closer to his Mum's bedroom door, which was open. There was a dresser across from the bottom of her bed, and he looked at the mirror, seeing his Mum, naked on the bed, her legs open, rubbing her pussy, and fingering herself frantically. He stood, bolted to the spot, not believing what he was seeing.
She writhed around on the bed, rubbing her breasts and bringing her fingers up from her pussy, then sucking and licking them. Scott's cock was solid, and he slipped his zip down, letting it out so he could play with himself. He had often secretly admired his Mum when she was wearing a bikini, but he never thought he'd see something like this, and he was awestruck.
She looked so beautiful, and how lucky the men were who'd been with her, he thought. He moved closer, quietly wanking himself as his mouth watered watching his Mum pleasuring herself so beautifully. He watched as she began to come, shuddering and jerking her body on the bed, rubbing furiously at her clit, and as she was lost in ecstasy, he felt himself about to come. He must have made a sound and his Mum sat up, startled, and gasped as she saw him, come shooting from his cock, landing on her bedroom carpet about four feet ahead of him.
"Oh, God, I'm sorry Mum, I couldn't help it!" he cried while still finishing his ejaculation.
"Where did you come from Scott, you weren't supposed to be back until tomorrow." she yelled.
"No Mum, it's today, I just got dropped off."
She was still naked, holding her hand over her breasts, and her legs crossed. Scott moved closer, and she told him to stop.
"I need a hug Mum, please!" he said, "I've been gone for weeks."
"Well, put that thing away for God's sake, I can't believe you just did that."
"Mum, I just did the same thing you did!"
"But you did it watching me Scott!" she said, looking like she was going to cry.
"Mum, you're beautiful, how could I look away once I saw you?"
He sat down next to her on the bed, and he put his arms around her, holding her naked body, tightly against him.
"I've missed you so much Mum, I really have."
She put her arms around him, telling him she was sorry for what he'd seen. He didn't want her to be sorry, he couldn't tell her what he really wanted her to do, and as they held each other, he felt his cock swell once more. He looked down at her, between her legs, wondering what it would be like to touch her, taste her, and to be inside her, filling her with his seed, rather than spilling it on her bedroom floor.
She told him she needed to dress, and as he stood up, she realized he was solid, and she couldn't help but have dirty thoughts too. She looked up at him, and he smiled.
