She giggled, running her hand lightly over it’s length. “It’s a little something we whipped up at the meeting. I’ll show you in bed. I think you’ll like it.”

My wife’s a witch, so I know what a ceremonial dagger looks like, although I had never seen one so ornate and studded with gems. She’s not the evil kind of witch from folklore with a wart on her nose – she’s actually really nice looking, with large firm breasts and a beautiful face. Nor can she make things appear when she twitches her nose – magic doesn’t work like that, although I’ve known her to accomplish some amazing things at the weekly meetings of her circle. Which was where she’d been today, incidently.

“In bed?” I asked. “It’s magic for sex? But I’m not having any problems.”

She laughed again. “I know that, silly. This will make it even better.”

I generally have dinner ready when she gets back on her meeting days; she’s always hungry afterwards, and sometimes she can be pretty tired out, too. I put the dishes of food on the dining table and started cutting the roast.

“How’s a knife going to make sex better, honey?” I asked.

She was digging into her salad vigorously, and I had to wait a moment before she could answer. “Well, I guess I ought tell you a little about it so you won’t freak out.”

She paused a moment, thinking, before going on. “It’s enchanted. Those stones on it are actually controls. It can be made so that if you use it to cut something off, it grows back almost immediately, but as the opposite sex. So if I cut off you penis, it would grow back as a clit. Or I can adjust the settings so it heals up like you’d been born without one, and then make it grow back later if I want.” She grinned.

It took me a moment to fully understand what she was saying, and I felt my cock harden abruptly to it’s full length as I saw some of the possibilities. I swallowed with a click.

“Is it safe?”

She took another mouthful, chewed and swallowed, before answering me.

“Oh, yes. It’s made so it can’t do any serious damage – if you tried, it would just regenerate. I’d like to start somewhat slow with it, though. I’ve got a fantasy in mind I’d like to do with you tonight, then tomorrow we can try some other things. Okay?”

I nodded eagerly.

I barely noticed the rest of dinner, my penis remained rock hard and throbbing, and there was a feeling of giddy excitement in the pit of my stomach. I kept on snatching glances at the knife while I ate.

Soon my wife finished, and picking up the knife smiled seductively at me and walked off toward the bedroom. I followed eagerly.

She set the knife down on the bedside table and turned to me. “Lets start off normally. Try not to cum too soon, okay? You’ll know when I want you to.”

I nodded and started to undress her. As I said, my wife is really nice looking. Five feet nine inches, one-ten pounds, blond hair and green eyes, nice big breasts, narrow waist above good hips and a nice ass, and a really pretty face. Even without the thought of the knife the sight of her really turns me on, and as she pulled down my pants my penis popped out erect and purple with bulging veins, at least nine inches long.

She grinned at the sight and ran her hand down it’s length, then looked up at me as she guided it into her wet pussy.

“This is the last time you’ll ever put this inside me,” she said, and I felt my cock get even harder at the thought.

I held back and controlled my urge to ejaculate as I thrust into her, and after a bit I felt her stiffen and moan in her orgasm. I started to cum, then, too, but she reached down and pressed my urethra closed at the base of my cock.

“Wait,” she grasped. “One moment more.”

She moved her other hand over to the table and grasped the knife, then brought it down and laid the edge against the base of my throbbing cock. Oh my god! I thought. She’s really going to cut it off! Her other hand felt like it was red hot on my cock’s flesh, and knew I was seconds away from an orgasm.

“Quick!” I gasped.

She looked me in the eyes for a moment, then passed the knife through the very base of my cock. It went through without resistance. There was no pain or blood. I felt my cock suddenly go numb, the feeling of her hand gripping the throbbing shaft gone, and as she pulled it away from my body I saw the skin around my suddenly exposed pee hole heal up in an instant. My groin above my balls was perfectly flat. I came a secondly later, whitish sperm shooting out of the small hole in my crotch onto my severed penis in her hand, the orgasm oddly spread out and defuse. She dropped the cock on her stomach with a wet little thump, and wrapped her legs around me and gripped me tightly against her as she also orgasmed again, the pressure pushing the head my severed cock into my bellybutton.

She moaned and spasmed a few more times, then after a minute her grip relaxed and gradually her breathing grew calm. She was asleep. The meeting must have taken a lot out of her.

I pulled gently out of her grip and stood beside the bed, looking from my severed penis lying on her stomach, which looked even bigger now that it wasn’t attached to anything, to my crotch, where my stomach extended down flat past where my penis had been, until my balls hung alone between my legs. There was no sign I had ever had a penis, just the tiny round pee hole.

The sight brought a surge of lust and excitement and I lowered and hand and rubbed the skin around the pee hole. It felt no more sensitive the rest of my body, and after a bit I squeezed my hanging balls in frustration, feeling the dull ache of pain.

I needed to take a leak. Perhaps that would release some of the hornyness.

I started to walk towards the bathroom, feeling only my balls move between my legs, nothing from my cock because I didn’t have one any more, then paused and went back to my sleeping wife. My cock was still lying on her belly, huge and purple, the skin at the base all healed up around the hole, so that if you didn’t know better you’d think it was perfectly natural and had never been attached to anything. It was at least ten inches, thick and covered with steams of white cum. It must have engorged even more with the excitement in the moment she cut it off.

I picked it up and turned back towards the bathroom, turning it in my and examining it as I walked. I had never seen it like this, of course, and it looked new and strange, the large purple bulbous head shiny and stretched, the foreskin held back by the lip of the glands, and I had never seen the seam on the underside so clearly. It was growing cool to the touch, but still looked alive, the veins in it’s surface bulging, the color a healthy pink and purple. The knife must have some sort of preserving affect, I thought.

I washed my cock off in the bathroom sink, feeling another frustrating surge of excitement as I rubbed it in the warm water without feeling even a twinge of sensation, then set it beside the sink and sat on the toilet to piss. It was impossible to stand, of course.

I started to let go, and a dribble of warm fluid arced out of the hole where my large cock used to be attached, and down onto my ball sack.

“Damn!” I said.

I didn’t like pissing on my balls. It annoyed me. They annoyed me. They throbbed with blue balls, a frustrating pulse, and I couldn’t seem to get off without my cock attached. I wished I could...

An idea came into my mind, and I shook off my balls and stood, wiping them with toilet paper, before walking back into the bedroom. She had said it was safe. It took my eyes a moment to adjust to the dimness, then I saw the knife and picked it up, being careful to touch none of the jewels, and walked back into the bathroom with it.

There was a way to get rid of the frustration in my balls, and be able to take a leak without the indignity of dribbling all over them. It would be kind of cool, too.

More throbbing of blue balls, and I winced in frustration and pain. They weren’t much use attached. Totally useless in fact.

I pulled my nut sack out away from my body as far as I could, my hand looped around it above my balls, placed the knife against the base, and sliced it off. As before there was no pain, and pulling the sack away from my body, I saw the cut ends heal together turning the ball sack into a rough oval. I set I down on the counter beside my penis and looked at my groin. It was now empty and smooth, the only sign of my balls a slight depression in the skin.

I chuckled and ran my hand over it. It felt very odd, as though my cock and balls were totally numb, but the truth was much weirder. My genitals were completely gone, sitting on the counter top in front of me. It solved my blue balls problem, anyway.

I sat and a took a piss, the feeling strange because I wasn’t going through my penis. I would never piss through the penis I was born with again, the organ which had grown large between my legs as I became a man. Never have sex with it again, either. Damn this was odd. Exciting though, too. If I’d still had a cock it would have been rock hard. Just like the one lying in the counter, I thought, and laughed.

The flow of urine was uncontrolled and raged, more of a spray than a stream. After I finished I stood and wiped, feeling the strange numbness feeling in my groin again, then picked up my penis. Hmmm, I thought. There’s one thing I’ve always wanted to do with my dick, but couldn’t, that I can try now.

I brought it slowly to my mouth, and pressed the great dark head between my lips into my mouth. It nearly filled my mouth. I had washed it thoroughly, so there was no taste. It was hard and slightly rubbery between my teeth. I ran my tongue around the knob, wishing it was somehow still attached so I could feel it. When I sucked a stream of air entered my mouth. through the urethra from the cut end.

I slid my hand down between my legs, feeling a shock of surprise as I found only empty air where my penis and balls should have been, even though I was sucking on my severed cock. Damn, this was weird. Awesome, but weird.

I took my penis out of my mouth and wiped the saliva off on the sparse hair of my groin, feeling a thrill of excitement as I rubbed my dick head on the skin where the base of my penis used to be attached. Then I walked back into the bedroom and climbed into bed with my wife, setting my cock down on the night table. The feeling of walking without nothing hanging between my legs, no swaying or movement, was also strange. She mutter sleepily and turned towards me, pressing her breasts into my chest. I kissed her lightly and pushed my empty crotch into her’s. Nothing touched her pussy, of course. I had nothing projecting down there that could push into her. My crotch was now as smooth as hers was. Smoother, in fact.

I woke up the next morning to find her already in the shower. She came out as I was still stumbling out of bed, feeling a sense of unreality as I saw my penis lying on the table beside the bed and ran hand over my smooth, empty crotch.

She was holding my balls in one hand. “Got frustrated and decided to make it better, eh?” she asked.

I nodded, grinning slightly.

“I’d say, ‘bad boy,’ but I guess I can’t with any accuracy, can I?”

“Nope,” I said. “Not a boy any more.”

“I have to run down to my circle and help them get another knife ready,” she said as she threw on some clothes. “I’ll be back in a few hours, and we can try it out some more, but for now I’ve got to take it with me. I don’t want you getting frustrated while I’m gone, though, so let me give you a little something.”

She picked up the knife and pressed her thumb into a blue gem in the hilt until it glowed softly for a second, then walked over to me and drew the point down over my groin, penetrating the skin deeply in places.

“Ow!” I said, not because it hurt, but from surprise. A delicious tingling sensation spread from the cut to cover the my whole body. It felt like I was being stroked all over with feathers, only better, and I lay back on the bed as a wave of dizziness passed over me.

“Don’t worry.” she said. “It won’t hurt you. Have fun. See you soon!” She paused for a moment to tweak my penis where it lay on the bed table, then walked out the door carrying the knife.

I barely noticed. The dizziness had mostly passed, and the tingling feeling had centered in my waist, hips, and chest. As I watched, my chest expanded into a pair of large breasts, and looking down I saw my hips expand and my waist narrow. My groin dimpled inward where my balls had been, and a slit formed, it’s top a tiny nub extending almost up to where my penis used to be. My skin became smooth and silky, and as I touched my long flowing hair I saw my hands were small and feminine. I was a woman.

I slid my fingers down to my crotch and felt the slit there, lightly tweaking the nub of my clitoris at the top. The feeling was wonderful, encompassing my entire body, flowing up to my breasts. It was much better than any sensation I had ever had from my penis.

The thought made me look at the side table, and I reached out my hand, missing on the first try due to my shorter arm, and picked up my penis. It was cold, but still looked just the same as last night, healthy and erect. I put it in the space between my breasts, pressing the breasts together on it and breathing down between them to warm it, then brought it down between my legs. The head seemed too large to fit inside me, so I pressed the base into my pussy a few inches and squeezed the muscles in my groin to hold it.

The feeling of being penetrated was amazing, an empty, aching space inside me being filled. I looked down at my erect severed cock poking seven inches out of my pussy, the head huge and purple with engorged blood, and stroked my hand up and down it as though masturbating, holding it firm with the muscles of my vagina. I got up off the bed and walked over to the full length mirror, my severed cock still held between my legs, and looked at myself.

I looked amazing. I was a beautiful woman, with large breasts and a stunning body, and between my legs, poking out of my pussy, was the largest, most erect penis I had ever seen. I could say that if I still had a penis it would have been erect, but I did have one, and it was. It just wasn’t attached, completely numb as I gripped it and moved my small hand up and down it’s length, trying to jack off.

I pulled it out of my vagina and dropped it on the floor, then looked at my empty, female groin in the mirror, imagining grabbing the woman in the mirror and thrusting my huge erect – and still attached cock – into her. God was I hot! Without a doubt, completely female, and beautiful.
