Chapter 6

Zach was getting the hang of it. Blake’s body, while familiar, felt very distinct from his mothers. What caught his attention the most was the smell. While his mother had been clean that morning, and had only started to smell of sweat as he used her during the early afternoon, Blake had spent the day at a gym, so every moment he spent in her body, he was accompanied by her own body odor.

He hadn’t thought about it before, but when he was in there, it was a distinct reminder that she had spent the whole day doing all sorts of stuff, and he could easily just take it for himself to use as he wished.

While he was inside her, feeling the mix between her perfume and natural musk had made him so horny that he could hardly believe he waited that long before starting to masturbate.

But he held on, trying to do things before beginning to pleasure himself. If his predictions were correct, like his mom not wearing a bra today, if he consistently acted a certain way, his hosts would eventually adapt said behavior for themselves. Fortunately, he had a lot of time to play and experiment with it.

After leaving Blake’s toned body, Zach masturbated once as himself, before playing some games, waiting for dinner to be ready. Beyond everything he did today, waking up with his sister’s used underwear was definitely not something he was expecting to do today, but he made good use of it while pleasing himself.

Still he had to sleep properly tonight, so he’d have tomorrow’s entire day to play with his family, so he dutifully went down and ate with his mom and Blake.

His mother warned him that she’d be making his cakes tomorrow, meaning he’d have a very brief window he could spike the ingredients with his nanobots. He didn’t know much about how baking’s chemistry worked, but he hoped the nanobots wouldn’t stop the cake from working out.

Later, after everyone went to sleep, but before Charlie arrived from whatever she had gone, Zach snuck downstairs and mixed the nanobots with the sugar, flour and the milk his mother had bought to make the cakes and the frosting. Once he delivered them, by this time next week, he’d have at least 5 more nodes in his network.

It was a little after noon when Zach woke up the next day. He could barely believe that he had spent a not insignificant amount of time as his mother and one of his sisters yesterday. Before leaving the room, he checked the server, and saw that Charlie was already home. His first instinct was to jack in her head, and have some fun, but he held himself. He had done a lot yesterday, so he wanted to check the lay of the land first- seeing if his mom or Blake had any noticeable effect from his time inside them.

As he went down to the kitchen, he bumped into his mom.

“Oh, good afternoon, Zach. I was just going upstairs to wake you up. Lunch is almost ready.”

“Oh, thanks mom.”

Zach did notice that his mother’s eyes lingered on his crotch a bit when she first saw him, but after catching herself and blushing, she quickly averted her eyes. Once she turned her back to him, he also noticed she lacked a bra strap. Zach quietly smiled, his actions already making a noticeable change in his mother’s actions.

Downstairs, he helped his mother in the kitchen, setting the table, and cleaning some of the remaining dishes in the sink. Half an hour later, his sisters also came downstairs to have a family lunch.

It was a pleasant time, all four of them making small talk. Blake talked about her work, while Charlie talked about her last few classes and internship. Alice told Zach that his cakes only need frosting before being ready. After they were all finished, Zach and his mom went to the living room to watch a movie on the TV, while the sisters washed the new dishes, and stored any remaining food.

Zach really enjoyed seeing how close his mom was sitting to him on the couch, her hands caressing his legs every so often. After 15 minutes, Zach’s sisters finished their chores, and sat down to see the movie too.

Zach noticed that Blake seemed a little uncomfortable. She would every so often try to discreetly sniff herself, her face blushing every time she thought she got away with it.

On the other hand, Charlie was as normal as she could be. Zach noticed that she also realized something weird was going on with their mom and sisters, giving them silent looks every so often.

Knowing that he was the reason for both his mom and Blake’s unusual behavior, was very hot for him.

Once the movie finished, Alice informed Zach that she would be finishing the cakes, so he could deliver them in two hours. Charlie and Blake both went to their rooms, and so did Zach.

He checked the server, named the only remaining node as Charlie, and got ready to jack in. He had some fun to have with his remaining sister, and he could barely wait to decide what he’d try to program her into liking.
