"Damn right they don't. What's happening with your neck?"
"What do you mean?" I turned my head to look at my own neck, before realising that I'd never looked at my own neck before, because biology normally prohibits it. But my neck was now long and flexible enough to allow it. "How strange. Whatever it is, it looks like it's the same thing that's happening with your cock."
Patrick's cock was still growing in length while maintaining the same thickness. It was now as long as his forearm. It rippled and undulated like a snake.
"Is it doing that by itself, or are you controlling it?" I asked.
His cock wriggled over and poked me in the boob.
"Does that answer your question?" he giggled, rhetorically.
"This is fucking weird," I mumbled, though taking a peculiar enjoyment in being able to move my head around on the top of my serpentine neck, weaving my way around the back to get an unfamiliar view of my shoulder blades for the first time. "I can definitely see how some people might find this disturbing. Definitely not for the unadventurous."
"It's a bit silly really," he said, wriggling his cock over and trying to nuzzle it into the palm of my hand like an eager puppy. "The question is," he asked, glancing at the clock and seeing scant minutes remaining until midnight, "are you feeling adventurous?"
While it's true that I did miss that feeling of overwhelming calmness that accompanied the usual use of the collar, I was still getting some of the benefits. I still felt devoid of inhibition, and that familiar craving for pleasure was making its presence known. The bed was now covered by two intertwining tentacles - Patrick's narrow, robust cock, and my pale neck - and it was impossible to estimate how long they had reached. Amongst the undulating flesh, I spotted the tip of his cock, and possessed by an insatiable hunger, I darted my head towards it. I opened my mouth to take it into my throat, and then began the long journey of chasing along its length in search of its elusive base.
Pleasurable as this was, I wanted more. As my head continued to make its way further and further down, I climbed to my hands and knees and rotated to position my pussy above where I thought Patrick's face probably was, though it was impossible to confirm this as I no longer had any sense of where my body was in relation to my head. As I lowered myself gently, I felt the tip of his tongue touch me, and knew that I was in the right place. Just that first touch sent jolts of pleasure sparking through me, and so I straightened my arms and allowed my backside to drop a little further so that he might go deeper.
Suddenly my head collided with Patrick's crotch. Our bodies had stopped changing, and my long sinuous neck was now filled end-to-end with his tentacle. I was, by now, more neck than body, and so I felt more filled by him than I ever had before. His cock inside me was strong and flexible, and I could feel myself being pushed around as it lashed about. I moaned with pleasure as he slurped at my wet pussy, and I could feel the first lights of an orgasm peeking over the horizon.
Suddenly there was a cut in my perception of the world around me, like the moment when you wake up after having been under a general anaesthetic, and are unable to establish continuity with the time you existed in before. I felt that glorious calmness hit that I get when the collar first goes on. My face was no longer pressed against Patrick's balls, and I was now staring at the bedroom wall, frozen in position. I could still feel Patrick industriously working away with his tongue, enjoying the taste of my pussy, though I was now forced into immobile silence. But even if I had been able to speak, there would have been nothing I could say that would do justice to the supernatural sensations that made my body now feel like a star going supernova.
After a little while Patrick stopped licking and pushed me easily to the side.
"It's a very convenient side effect how you get so much lighter when we both have our collars on. Otherwise I worry I'd be at risk of getting suffocated under there. Oh, and you probably knew this already, but it's past midnight."
