Sara had fucked her own son. This wasn't some crazy fantasy she'd had in some guilty dream that had snuck up from her subconscious, she had fucked Sam, her own son. She much preferred to think that he'd fucked her, that she'd try to stop him, but she knew deep down that she could have stopped him if she wanted to, and she didn't. That kept her awake at night, thinking that as much as Sam had forced himself upon her, she trusted him to stop if she asked him to; and she didn't ask.
What she kept thinking about was the fact that there must have been signs before that day, that maybe there were hints or moments she didn't pick up on that led Sam to doing something like this to her. She thought back to the months he'd been back home, and she thought about him and how he'd acted, and that maybe she might had missed a lot more than she realised. All she thought was that he was loving being home again, that he enjoyed living with his mother and father, and all he was doing was showing his appreciation. She was sure that was part of it, her husband, Colin, had mentioned that Sam was loving getting to do things with his father again, and that he was loving getting to know his him as a fellow adult. This echoed something that Sam had said to her, though now she realised that perhaps is might have implied more than she thought; Sam had told her at one point that he enjoyed spending time with her now, and that it was amazing to see her not just as his mom, but as a woman. No alarm bells sounded at the time, but now it had been marked as a missed red flag.
To add to this, she knew that Sam wasn't hiding his looks at her here and there. He had always been a little impulsive like that, it was hard when she was a woman with certain proportions that were very noticeable, as she knew she couldn't keep them always hidden. If she ever wore a low-cut top, there was a lot of cleavage showing, and she knew that whenever she wore anything even slightly revealing that any man's eyes would be drawn to that; or her sizable behind in a bikini, she knew that she had some weight back there, and was proud of it, also knowing the attention it garnered her. With it currently being the height of summer, it was hard to wear clothes that could cover either of her assets and keep her at a comfortable temperature, so Sam's eyes occasionally being drawn to her body was not unusual at all. All that being said, when he came back from college, he had stopped hiding his looks over her, and she'd called him out on it once, but he confidently admitted to it and apologised to her. Again, another missed flag. There were so many things she was thinking about now that she missed, all the small details she thought was just her son growing up and being more confident and mature. But that's the thing, he was more confident and more mature, besides that encounter in the kitchen, she was looking at him as a man more than her son.
The last thing she hated to admit was that her thoughts when she was pleasing herself, or when she was in bed with her husband might have drifted to her son in the past, in the past week, all she could think about was her son's hands and his cock. As she let her husband fuck her, she pictured her son doing it, and she just knew that he could do it better. She was so worried that the next time Sam tried to make a move, she wouldn't be able to say no; though it wasn't like she was able to last time either.

It was an incredibly hot day, and with all the housework done, with her husband still at work, and Sam out with his friends for the day, Sara decided it was one of the only opportunities to have some time in the sun. She had time like this every now and then, but especially in the last week, she'd been nervous to go out and sunbath with her son still in the house. A part of her seemed to want that, that the idea she was outside in her bikini for her son to see would be something she'd like, but the realistic side of her knew that with what happened before, she might feel a little bit on edge about being out there in his view.
It was sometime in the late afternoon, and she'd been out there for about an hour at this point, making sure to keep her body covered in tanning oil as to not burn and make sure she had a nice tan all over. She was even careful about tan lines as well, wearing a small bikini as to cover as little skin as possible. The bikini she was wearing was small for her, she saw younger women walking around in much less than this at the beach, but this was the closest to a thong she ever wore, and while she knew some of the neighbours might get a look at her, she would never wear this outside the privacy of her own garden; and now with the situation with Sam, she'd likely never wear it if he was around either.
She lay there, the sun beating down on her back, in a state of almost nirvana. She had a book she'd read a few pages from here and there, but laying there with her eyes close seemed to just calm everything down for Sara, letting her mind slip away into a peaceful state. She wasn't asleep, but her head was empty, only thinking about the moment and how pleasant this was. She was free from all tension and guilt, as if nothing mattered to her anymore.
She heard a sound from in the house, not opening her eyes to see what it was, she was too far gone for that now. She assumed Colin had gotten home, she heard him go upstairs, then a few minutes later come down and then finally come out into the backyard via the sliding door. She heard it run along the runners and then shut again. She then said,
"Honey, do you think you could come and rub in some oil for me?" She held up the bottle, her eyes still closed as to not accidentally look directly into the sun.
"Sure mom." She froze. That wasn't her husband at all, that was Sam. Her eyes snapped open and looked up at her son, reaching out to take the bottle from her. He had a big smile across his face, a kind, warm smile, but with a dangerous twinkle in his eyes that she recognised from all the men she'd had in her life.
"Oh Sam, I... I thought you were your father." She looked back at him, realised that he was topless, only wearing a pair of swimming shorts. He looked good, he wasn't the most athletic guy in the world, but Sam was handsome and charming, and he felt confident in his own skin. Sara then realised far too late that her eyes had basically done an entire sweep of his body, paying particularly close attention to the loose fabric between his legs, looking for something, anything that might give her an impressive visual indication of what she'd previously felt inside her.
"Oh, don't worry Mom, I'll do it for you." He took the bottle from her hand and flicked it open; his smile was that of a man who was out for something, something he knew he could get. She watched him squeeze the oil onto one hand, put down the bottle and spread it over both his palms, "Just relax, I'll take it from here, don't worry." Sara put her head back down, still able to get a small glimpse back at Sam.
"I thought..." she began to stutter, "I'm sure your father will be coming home soon." She was buying time, trying to basically avoid the inevitable.
"No, it's still early, he won't be back for at least another hour, likely longer knowing him." Sam laughed. Sara must have not been here for as long as she thought, meaning it wasn't getting towards the early evening, it was so hard to tell here in the height of summer. She felt her son's hands make contact with her calves, a little jolt going through her as they did, with a regretful moan escaping her lips. She looked back at him again, smiling a little awkwardly; he gave her that kind smile in response, then giving her a little wink. She quickly put her head back down, worried for the afternoon ahead.
