During the night, Lisa occasionally felt her other selves, lying atop her mattress-topper form, shift, and she noticed that some of them shrank considerably. At first she thought one had disappeared. She didn't feel any self merging with her, but she thought maybe one of herselves might have merged with another. But then she realized that she did still feel some weight on her surface, where that self had been. Not as much weight, over not as much area. Oh! she thought! That me transformed into a kitten. She'd really enjoyed the kitten form the times she had experienced it, including several times recently as a kitten lying on top of her mattress topper form, as now. So she wasn't surprised if one of her selves wanted to do that.
What did surprise her a bit was that at various times during the night, she experienced the same thing again. By morning, all six of her other selves, previously in human form (but with cocks) had become kittens. She woke up feeling rested, though she didn't know what time it was. Her alarm clock hadn't gone off yet. She said, to herselves, "Wake up now, please, and transform back to human form." Nothing happened, so she had to repeat herself, louder, a few times. She felt a few kittens shift, and heard a few meows, but then she felt her selves transforming again.
"I said we'd merge in the morning," she told herselves, "and we will do that, but if you don't mind, let's please fuck ourselves again first."
"Sure," one of herselves said, and she heard agreement from others, and then started feeling herselves position themselves atop her surface, and start penetrating her. They didn't push things as far as the night before, but it was still a good start to the morning. After she and herselves each had several orgasms, she asked, "Ready to merge?" All of her happily did so, and so in addition to her mattress topper memories, she gained the memories of having been each of her half-dozen other selves, first as human, with cocks, fucking her, crawling inside her, fucking her again from the inside, crawling back out, sleeping, becoming kittens, and fucking again in the morning. It was always amazing merging and having the memories from multiple viewpoints.
With Ty, she had been multiple cocks, when she had been one of his cocks and then he'd duplicated it. He initially hadn't thought about the fact that he was copying her. But he hadn't yet seen how she had taken the ability to duplicate herself, and run with it. He was going to be quite surprised, she thought, but I hope he likes it. I want to do a lot of things with him as multiples.
And, she remembered, she actually still had another self that currently was his cock, which she had secretly duplicated into him a few days ago in the school cafeteria. She wondered how that self was getting along, and looked forward to merging to gain those memories. She started getting a little bit worried about what Ty's reaction to learning about that would be, given that she hadn't asked his permission. But she hoped he would find it a pleasant surprise.
Her alarm went off, so she transformed her now single self (aside from the one other herself in Ty's cock) back into her mundane, boring human form, to start her day. She was happy that the end of her grounding was now a day closer. The end was finally in sight.
