Meanwhile, Kelly had taken a break from emails. She decided to gather up the tail that had been laying on the floor. She folded and put it back in the box. There she found a sheet of instructions. She skimmed over it looking for the important information.
"Pull the tail up to your waist to start the transformation. Transformation speed will vary by temperature of the air and material."
"Orgasms may cause further changes."
"To return to human form, avoid orgasm for 24 hours."
"If transformed for 7 consecutive days, changes will start to become permanent and will be completely permanent after 14 days."
"Pregnancy can occur while transformed, with a human or another lamia. Egg-laying may occur even after returning to human form. Hormonal changes caused by pregnancy may prevent a complete return to human form."
"The tail is intended for female use. A male triggering the transformation will become female for the duration of their transformation. Males will take 48 hours without orgasm to return to human form. If impregnated, a formerly male subject will remain female after returning to human form."
Kelly took a moment to process all of this. She had Jake would be human again if they avoided sex for a day, which they needed to do within the next week. Since they were both female pregnancy didn't seem to be an issue, but it would be something Kelly would have to watch out for next time she transformed and Jake didn't.
She sensed something unusual and tasted the air. Jake was very aroused! Then her door opened and there was Jake. She could see the scales around Jake's cloaca area glistening with moisture. His face was red and shirt seemed tight.
"Kelly...I need you...pleasssseeee..." Jake panted.
She slithered over. "Exciting meeting?" she teased.
"I'm changing further" Jake said and began slowly unbuttoning his shirt to reveal his slowly-developing breasts.
Kelly got excited and immediately cupped and caressed the two fleshy mounds. "I bet these will be even bigger after you orgasm."
"I want you to go down on me with your ssssnake tongue, like I did for you earlier."
"With pleasure. Let's go to the bedroom..." suggested Kelly
"Or we could do it right here..." replied Jake, not wanting to wait any longer.
