I was really not sure about it, but… it did seem like a good idea.

A research of Jonas Hamesol, centered around keeping separated body parts alive, clean and in contact with eachother, seemed to check out, at least in theory.

Small-scaled test, done with the tip of the tail, seemed to work, more or less (and if it didn't, the tail would've regenerated anyways), so, I've decided to go for the big goal right from get-go.

Getting the runic structure, derived from a "healing" rune, going under my own scales on all three necks wasn't terribly easy, but, with some practice in flesh-shaping, it was done sooner than later. After that, I poured magic into them, until I felt they were ready. And then…

I've picked up a large, enchanted blade, made by Hamesol himself, sharp as a razor and took a long, inquisitive look at it. If everything works well, I won't even feel any pain, as it cleaves through my flesh without doing any actual harm. If not… well, I'll still have two more heads and, hopefully, enough time to call for help. Maybe even regrow the missing head later.

After some more time spent in consideration, I've finally gathered enough courage and hacked my left head off in a single swift move.

Thankfully, it seemed that I've done everything right, because the blade immediately homed onto the runic structure and, interacting with it, somehow separated flesh and bone in space without actually damaging them and without dealing any pain. After I cut my head off, I picked it up and took a good, long look at the separation plane - at the blood vessels, still full and going, at the spinal cord and vertebrae… it was quite the view indeed. Especially since it was also protected against foreign materials by the same magic that made this all possible.

However, it was now the time for the second test. I've put my left head back, feeling the flesh fusing, and tried to pull it off - to no avail, just as I wanted. Moreover, when I've decided I actually wanted it off, it got disconnected from my neck with no problems.

Inspired by this success, I've repeated this all with my right and central heads, making sure to have the cuts be identical and positioning my heads around my body. Weirdly enough, it seemed like a portal connection in the esophagus could be switched on and off at will… but it was something for slightly later.

Right now, though, I've been looking all over myself and noticed how my cloacal vent was a tiny bit swollen, with hemis barely poking through, and got an idea. I've taken a seat on a chair, put my central head against my feminine opening and used my left and right heads to stimulate my hemis.

The feeling was heavenly. As I knew, what I wanted, I could adjust the actions instantly to maximize the pleasure (which I did), allowing my hemis to extend to a full size in no time, leaking salty precum, while my feminine opening also got a very fair share of attention. It was rather peculiar, how I could swallow without having the liquids splash out from my necks (though it could be adjusted), but, as for now, it took a secondary priority to getting myself to the peak of pleasure…

Which I did rather soon, streams of salty precum turning into spurts of cum proper and feminine opening leaking sexual fluids too. And feeling it all from so close… I don't think any other sensation could compare. After cleaning myself up (mostly by licking any spills clean) and re-attaching my heads, I've decided to go with a report… and, maybe, convince someone else to undergo this too.

After all, it was really a good idea this time.

A few days after that event, as well as sharing it with some volunteers and assisting them in it, I've felt a need to experiment a bit more. As well as to try out some alterations I've done to my reproductive system…

After walking into a secluded enough place with a willing partner for this one experiment (Niyra Jesnoa, three-headed wingless copper dragonborn. Three heads, in general, were considered to be just the right quantity for those who wanted more than one), I took off my left and right heads and positioned them to have a good look from the third person perspective, with Niyra mirroring my actions soon after.

As we both undressed, I took a note that Niyra preferred to style hir cloaca vertically, while I preferred more natural horizontal alignment. Still, it was worth trying out at some point…

Once we were both undressed and ready, I flipped a coin on who goes first and smiled, seeing it be me. Niyra, thankfully, seemed to be fine with this outcome too, taking a place on the bed and nodding to me with the remaining central head.

I nodded back, as I felt my hemis emerging. A small exertion of my will forced them to move closer, as I walked closer, though after a small word exchange with Niyra, I've also grabbed one head of mine and one of hirs for what was to come.

As both of my lengths entered hir feminine vent, I sighed, while Niyra moaned. Shortly after that, I nodded and concentrated, driving eggs (smaller than normal, and fully inert) from my uterus to my hemis, which I've made to double as ovipositors. Now here was hoping I did everything right…

Thankfully, it indeed appeared so - not only was the passage of eggs pleasurable to Niyra (though my left head and hir right head keeping hir hemis occupied helped), it was also pleasurable to me, as I felt them passing through my hemis and into Niyra, going all the way through female opening, vagina, cervix and right into hir uterus, each egg accompanied with a fair amount of lubrication.

Just as we both expected, around eight eggs later, we both reached climax, Niyra's hemis erupting with enough seed to splash us both, despite the best efforts of our heads. Shortly after, me and Niyra changed places and I got ready to be on the receiving side.

As Niyra's slick lengths entered me and reached up to my own cervix, I quickly found out that while being on the giving side was fairly pleasant, being on the receiving side was even more so. I couldn't last all eight before climaxing, and even before that, I was all but roaring from pleasure.

And as for what we did for last… Well, that was even more delightful, but that's a story for later.
