" He feels Mark moves about getting more comfortable. "Yes, thats the unique part about my tail is its holding sack. Its very comfy in there. I have had people how have enjoyed it so much they have spent days in there." He chuckles." Don't worry, I will not keep you there that long. I will let you shortly." He closes his eyes and murrs deeply feeling Mark move around some more. "Your getting sleepy, good, that  will make the next part easier." He chuckles ."Thats about it. Yep, she was watching with great interest. She will be in for a bigger surprise with what I am going to do next and that is letting you out." He rubs his belly some more. "The last part of the initiation is for me to reform you. Its quite painless. Your just going to fall asleep and when you wake up you will be back outside, alive and quite well. How does that sound? " He sighs getting moe comfortable. "When ever you are ready, I will begin. Just let me know."
