Working your hands up and down your disconnected shaft didn't help at first. It only looked more painful, the harder you pulled at the flaccid rod, to no avail. It continued to fall back down limp the moment you let go of it, lifeless like the rest of your detached lower body.
To try this, you'd have to figure out another way.
Luck had it that you were still holding onto the magic sword that made all this possible in the first place. Perhaps you could figure out another way to get what you wanted. You were over-eager to experiment with this new pair of womanly legs attached to your manly upper half. Sticking your own dick inside your new opening didn't sound half as strange as painlessly and effortlessly slicing your own body in two.
Mulling over your situation for a moment, sword in hand, you suddenly had an epiphany. By slicing off the skin from the small of your back, would reattaching your own lower body there have the same effect as attaching a completely alien bodypart to yourself?
You brought the sword behind you, making good use of the mirror to see where you were placing the sharp end. For a moment, you admired your newly improved ass, and the wetness of your new inner walls seemingly seeping out from your exposed crotch. You made a crevice on your back, and used your thumb and index finger to get in between the flap of loose skin you just managed to separate from the small of your back. Peeling further down, you finally sliced off the skin at the other end and, almost literally, threw the skin off your own skeleton. But again, there was no blood, and where the skin was peeled off, now appeared new skin, slightly off-colour.
The legs were still heavy in your arms, as you settled on picking them up and trying that way, to get them to reattach. Though no simple feat, when the top of your detached bottom half finally connected to the small of your back, you felt another surge of pleasure, and your second pair of legs reacted with jerks and spasms as you suddenly regained feeling of them.
Once that was over, you peeked over your shoulder and looked behind you. Your old ass was jutting further outward than usual, and you could actually feel your own hairy thighs slide over the smooth and shapely ass from your newly acquired lower body.
Sitting down, you found out that new, unfamiliar movements seemed to come almost naturally, first landing with your masculine butt on the bedside, and then letting your feminine hips rest on top of your own lap.
It felt really strange. It was as if your spine had elongated to account for your reshaping into what could essentially be called a centaur, albeit lacking the horse-parts, so a quadruped instead.
The sight was disorienting, though still very enticing.
And besides, you wondered, thrusting your feminine hips back and forth over your masculine legs, was that your own hard-on your pussy was rubbing up against?
