Before Dan began, Kat made a suggestion. “As much as I’d prefer it... I don’t think you can use your telepathy to cast this.”
“One stray thought and we might turn inside out...”
“Alright...” Dan answered with his mind.
It would be his last mental response for a few minutes. Kat held the book still as Dan spoke from their pussy. Vibrations sent shivers down his legs, making it hard to read. Dan forced himself to focus. At one point Kat couldn’t help stifling a moan. Dan ignored her quiet squeak and continued. After nearly twenty seconds of continuous stimulation, the spell was cast.
“Did it work?” Kat breathed.
Dan could feel wetness on the edge of his lips and switched back to his telepathy. “I’m not sure...”
“Wait... I feel something...”
Kat replied, “Oh... I feel it to. Like that pin prick feeling you get when you leg goes numb, but not as painful right? I feel it at the bottom of my stomach...”
“We’d better get into position.”
As they rearranged themselves, Kat noticed that her underside, along with the prickly feeling, felt really sticky against the bed sheets. She managed to pull herself free without leaving any sort of residue. With some effort she made herself comfortable at the head of the bed.
“Alright Dan, get in front of me and I’ll help you get centered.”
He scooted into a seated position just below his sister and laid back. She reached down and held either side of his waist to guide him into the sticky flesh. Once aligned she had him gently push himself up the bed until they made contact. Their separate parts almost felt magnetized as they came together with an abrupt slap. Kat was whole again, but there was a visible line around her waist. As it was, they could still be pulled apart with little effort.
“I guess that’s it... Now we just have to wait for it to finish.” Kat said as she stretched her arms and yawned.
“It’s almost midnight... We might as well sleep.”
“Yea...” Dan replied. “Goodnight Kat.”
“Night Dan...” Kat echoed.
She reached over and pulled a blanket across them, then cast a basic spell to turn off the lights. Dan felt a little funny as his body slowly merged into Kat’s top half. He was sad to lose his freedom, but knew that it was a necessary step towards recovery. The tingling subsided and he began to feel numb around his waist. He tried not to think about it and soon fell asleep. Kat felt her legs relax. It wasn’t long before she dozed off as well...
