Ty decided that the best way to gather the four billion Lisa shards, one from every human cock in the world, was going to be to make four billion copies of himself, one in each cock. In fact, that wasn't just the best way he could come up with. It was the only way. He knew that he had to be careful about the details. Unlike what he had done with Lisa, at her request, he very specifically needed to make full copies of himself, not split himself into parts. Doing that to Lisa was what caused this disaster!
Secondly, although he was going to become every cock, he had to be careful not to displace the Lisa fragments already in them. That should be easy, since each one was only one four billionth of a Lisa. He would become the rest.
Once a copy of him was in a cock, it would find the Lisa shard, then merge back into his own cock, carefully pulling the Lisa shard along.
Finally, when all the Lisa shards were in his own cock, and all the Ty copies had merged back together, all he'd have to do would be to reassemble the Lisa shards into the complete Lisa, and transform her back to human form.
It would be a piece of cake!
He thought about this plan, trying to identify any flaws or weaknesses, or any ways to simplify or improve it, but after several minutes he didn't come up with any changes. OK, Ty thought to himself. It's show time! He set Lisa's alarm clock back to normal time.
He transferred himself, his consciousness and essence, into his own cock. The whole process he had planned should only take a few minutes, and the rest of his body would be fine on its own for that long. He verifed that his mental metaphorical imaging system still let him find the Lisa shard in his own cock. Here goes, he thought. He duplicated himself into (most of) every human cock on the planet.
