A thought came to Jake's head that he didn't initially think of. Than he realized and looked down at Rex with a grin on his face. "What ya thinking down there?" Jake asked. "How about we make this more interesting. Get on the laptop." Jake walked over to his laptop waiting for Rex's instructions.
Rex insisted that their cum change people into half animals. On top of that, they'll have grown heads on there dicks. Even females grow their own dicks with heads. They added that cum only needs to make contact for the change to take effect. When changes occur, they'll get lustful, shooting out cum that can change people the same way. Jake added all the changes will be normal to everyone so no one gets freaked out. "This could be fun." Jake smiled at Rex and hit enter.
Jake didn't feel any initial change, however he did notice his balls slightly grew in size, probably because of his new cum which made Rex spit some out. "Alright. Now all we need is to find an oprotunity to use this." Rex said. Jake thought he knew exactly the place to do it.
