Having just masturbated to the same erotic audiobook chapter that his mom had earlier, Matt laid there, replaying the events in his head. After deciding it would be a one-off occurrence, and decided to keep his mind off it. He cleaned himself up with his t-shirt, buried it in his hamper, then grabbed some clean clothes and took a shower.
That evening at dinner they had their usual banter. Matt had cooked, as he did from time to time. Deb was pleasantly pleased with the food as always.
They chatted about her work, how she was easily able to shift her responsibilities, while Matt talked about what he learned in his morning class. Matt avoided bringing up the audiobook, and his of course mother didn't mention it.
While cleaning up dinner Matt asked his mother, "so what are you up to this evening?"
"I don't know really. I'm starting to realize how boring things are without being able to read social media," she laughed. "I'll probably just take a long bath then go to sleep early."
"Yeah, I'll probably go play some games myself. Do you need anything?" Matt asked.
"No, but if I do I'll have my trusty iPhone voice thingy message you," she laughed, waving her phone around.
Matt watched as she carefully got up from the table and left the kitchen, feeling her way with each step. He noticed how she was getting more comfortable with her temporary condition. He wondered how she would manage taking a bath, turning the water on, knowing how full it was, getting in and out... He thought about secretly keeping an eye on her, just in case she slipped or needed help. Some part of his brain told him it was for innocent reasons of course.
He quickly finished loading the dishwasher and crept upstairs to his mother's bedroom, knowing she never kept her door entirely shut. It was, after all, on the complete other side of the house, and she was never concerned about privacy before. He tip-toed, thankful that the upstairs had wall-to-wall carpeting. There at the bedroom door he watched her fish through her dresser for some clothes by touch, picking out a couple of items he couldn't quite see.
Then she turned and went into her bathroom. He followed her quietly and from the door watched as she set her clothes down, and busied herself getting her bath ready. She felt around for the faucet controls, the drain stopper, even feeling around until she found some bubble bath she liked. All this he quietly observed from the doorway.
He kept watching, his mother adjusting the temperature, retrieving clean towels from the closet. Without notice his mother pulled her top off, then undid her pants, slipping them down and stepping out of them, and carefully setting them on the counter where she would later be able to find them easily.
So there, before him, stood his mother in a see-through bra and panties set, with mismatched colors. The top was blueish see through, and showed off her amazing breasts and nipples. The bottoms were somewhat orange tinted, also see through, and showed off a bare pubic mound underneath. Matt's heart thundered in his chest, and he felt another erection growing.
