Jake thought he'd probably have some time before Leon was over with his thrilling experience of milking, so he had time to explain things. However, a gut feeling was bothering him... Or more likely a groin feeling. "What the hell?" Jake felt his crotch build up pressure, and he started panicking. "Wait, me too!? Why would I-" Than it hit him like the milk sprayed in his face earlier. "His milk landed in my mouth... And my snout..."
Jake acted quickly and slipped his pants off. He pulled down his drawers to see his udder was already spreading to his legs. "Oh... This is weird..." Jake's udder started inflating, filling up with his own milk. He rubbed his growth to try and calm himself, but it was only making him moan louder. His tail was swishing erratically as his teats developed. Spurts of milk came squirting out of his udder as he let out a vicious screech.
Leon finally calmed down only to see Jake rubbing an udder of his own. "Woah... Did I do that too?" Jake had already recovered from his udder developing only to look up to a confused bovine Leon.
This was gonna be tough for Jake to explain, even for himself.
