I heard the moaning the minute I opened the door and, I'll be honest, I was pretty sure Helen was upstairs having sex with someone that wasn't me. You know how your brain immediately jumps to the worst case scenario, even though somewhere inside you know that what you're thinking is almost statistically impossible. But your brain doesn't care. It always thinks the worst thing first.



And that's what I thought when I opened the door. I thought she was having an affair. I had no idea who it would be with, no one came to mind, but the way she was moaning, I was sure there was someone up there going to town on her.



Now, some people might have become immediately angry. They might have slammed the door and thrown their briefcase across the room before trudging upstairs like they wanted to kill someone. Most people would have lost their shit immediately. But not me.



No, I didn't fly off the handle. Instead, I went the other way. I shut the front door as quietly as I could and crept up the stairs carefully trying to remember every spot that creaked.



And then I was in front of the door. I heard the bed creak and then another soft moan. I stepped closer. I heard a slurping sound. I bet she's giving him a blowjob. And then, like my mind was one of those fast-forward movie montages, my brain showed me a thousand memories of my wife's blowjobs. God, she was good at giving head. Always had been.



Then I had another thought. What if it's a woman? Then I realized that I hadn't heard anything that led me to believe there was anyone else in the house. I got a sense that I was wrong. Something didn't make sense.



I took a deep breath and reached for the door handle. Whatever was going on, I was about to find out. I opened the door and found Helen. She was sitting up against the headboard, naked, and holding onto a trunk of flesh so large, she actually had the glans in her mouth. Yes, it had grown large enough that she could suck it and was apparently enjoying the new found sensation.







It had been two days since her cock had somehow manifested. We had originally thought that we would go to the hospital about it, but then, we hadn't. Neither one of us had any idea why it had happened. It simply had. At 2:30 in the morning, she woke up with a cock between her legs. She still had a vagina, still squarely nestled away under her engorged clit that had somehow evolved to expel more come than I had ever seen.



Naturally, the last few days had been interesting. We had both done in insane amount of research, you know trying our best to figure out what had caused the strange protrusion. And we had talked about it nonstop.



But I think the reason that we hadn't told anyone else about what had happened is because we both liked it. We hadn't said it out loud, but I think we both knew it, right from the start.







So, standing in the doorway watching my wife suck her own cock, I was both relieved and excited.



My brain shifted gears. My worry and fear about an affair were gone. No, as soon as I saw her, the first thought that crossed my mind was...Oh my God, that is so fucking sexy. And then I thought that I should probably tell her how I felt about her new accessory. I mean, I had been very careful when her clit expanded. Every time she had gotten a boner over the past couple of days, I had made sure that I had abstained from everything but scientific curiosity.



But in reality, I couldn't stop thinking about her cock. Every time I thought about it, my own dick would thicken.







It took her a second to realize that the door was open and I was standing there. I mean, it would have taken me a second too.



She turned her head and our eyes met. I saw fear, embarrassment, and something else, something I had never seen in Helen's eyes before. I don't really know how to describe it, it was like strength or confidence, maybe it was arrogance, but whatever it was kind of intimidating.



"Lucas? I..." she sputtered holding onto her cock with one hand while a copious amount of precum dribbled over her fingers. "...it came back. I was at school." Her hand continued to slide up and down her length while she spoke. "I don't know why. I don't know what happened." Her voice was a hoarse whisper.



And my cock was instantly hard. I looked down at hers. It was impossibly big. I mean, it was half the girth of my forearm and a solid ten or twelve inches. It glistened from the pre that she kept rubbing up and down.



There was a traffic jam of words in my head. Every nerve in my body was jangly. I wanted to tell her that ever since it had originally happened, I had been excited.



I don't know why I was so instantly attached to the thing. I mean, I had never been excited about another man's cock before, but when she had one? Oh, my god, it was all I had thought about. I can't tell you how many times I masturbated during those first few days. Every time I took a shit, I masturbated. To be honest, I was a little disappointed when it disappeared. But now that it was back. My mouth watered.



"I couldn't stop it. It just kept getting bigger." Helen's hand kept sliding up and down. "I don't know what to do? I can't seem to...it feels too good." Her breath came faster and I could tell she was getting close to the end.



"Hey," I loosened my tie and slipped it over my head. "It's fine, listen it's going to be okay." I moved toward the bed. I was worried she was going to panic. I tried to unbutton my shirt as fast as I could. This was my chance, I could feel it. I didn't take my eyes off it. It was mesmerizing watching her stroke herself. And I wanted in on it. I wanted to play too.



I gave up on the buttons and climbed on the bed.



Helen was sitting up against the headboard, her knees spread, her pussy had already left a wet spot on the blanket.



I stared at Helen, at the whole scene.. I couldn't believe how incredibly hot she was.



I reached into my pants and straightened my rigidity, I pointed it up to get it out of the way. My fingers came away wet and shiny.



"Lucas?" Helen looked at me and then at the protrusion along the front of my khakis. "Are you hard?"



It felt like time stopped, like everything suddenly just slowed to nothing. My brain froze. I couldn't think. I swallowed hard and glanced at her dick again. All I wanted to do was touch it, wrap my fingers around it. The fact that she was on the very edge of an orgasm was driving me mad. "I, um, you know, I mean you're obviously excited."



"This doesn't bother you?" She pushed her dick toward me and a drop of clear pre fell onto the bed.



I swallowed hard again. I could feel a cool sweat along my forehead. What if she didn't like my answer? There were so many ways this could go wrong. I was suddenly embarrassed and ashamed and terrified of losing her. "Sweetie, I mean, you know, if..." I looked at the throbbing cock she was holding onto and my own ached to be touched, "I love you no matter what." I said.



"Even if I have a cock?" she looked down at the tool in her hands, but I was sure I saw the trace of a grin across her lips. She liked it too.



"Sweetheart," I crawled closer, "I don't care." I reached out and wrapped my fingers around hers. "I am yours thick or thin." Her fingers were warm. She kept her grip and slowly moved her hand up and down.



But the increased pressure of my hand, made her shudder slightly. I looked over her body again. My cock had already left a wet mark on my pants. I couldn't believe this was happening.







Helen was the most beautiful girl I had ever dated. We met in college, she was studying education and I was studying architecture. I met her at a sorority function, she was a guest of one of the sisters. We has both been standing on the sidelines of the party when the quarterback for the team took a flying leap into the pool with all of his clothes on. Helen had leaned over to me and said: I never saw that coming. And that was it. We had been together ever since.



We were best friends. We did everything together. I had never had so much in common with another person or such a cool time hanging out with them. She was the best thing that had ever happened to me.



"Oh my god," she pulled her hand away and suddenly I was holding her new, giant cock.



The skin was hot. The tissue as hard as my own. "Don't stop!"



I cannot explain how amazing it felt to hold my wife's cock in my hand, to stroke it, or to see the look on her face. I don't think I had ever brought someone such pleasure in my life.



Another stream of clear pre oozed from her tip and rolled over my fingers. I used it like lotion and kept rubbing her dick.



"Oh, my God," Helen put her hands over her head and arched her back. "Yesss..." she whined.



I watched the pre surge from her hole again. I wanted to taste it. I moved closer to her, straddling her leg. I reached forward and slid a finger through the drop at her tip. I lifted it to my nose. I mean, what kind of pre did she have? Was it like mine? It looked like it.



With one hand stroking Helen's length, I wiped the finger across my tongue. The taste was sweet, almost like honey and it had a slippery texture, just for a second and then it was gone. "More," Helen reached over, took me by the wrist, and brought my other hand to her throbbing dick. "Don't stop," she moaned as I ran the palm of my hand over her spongy tip.



I looked down at what I was doing and then back at my wife's face. It didn't seem possible. How could she have a cock like this? And what else was happening to her?



She was different, even though I really couldn't put my finger on it. She seemed stronger, leaner maybe, like she had been working out and I hadn't noticed it before. Her breasts looked larger too.



I thought of how many times Helen had given me a hand job, how she had stroked me, her grip and how she concentrated on exactly what I liked. I glanced back at Helen's face. She was lost in ecstasy. I kept moving my hands sliding them up and down. All I wanted was to please her.



"Fuck, Lucas. Oh!" She looked at me with mad, crazy eyes. "Don't stop." She moved her hips in rhythm with my hands. "Oh, that feels so good!" She threw her head back and her cock jerked another stream of precum.



I kept moving, sliding my hands along her skin. Then I wondered what it would be like to be fucked in the ass. I wiped my palm through the clear liquid and lathered her pole as she fucked my hands.



And then she froze. She took a breath and I saw it catch in her throat. Her eyes closed and her jaw clenched.



I looked down just as her whole body trembled and the first bolt of cum surged into the air.



"Oh!" her eyes opened. "Oh fuck!" Her fingers dug into the blankets like she was holding on for dear life. Every muscle in her body flexed at once.



I aimed her cock at my face like it was a fire hose. I don't know why. It was selfish, but I wanted to feel her hot, sticky bliss, I wanted to be covered in her pleasure. Another stream splattered across my open shirt. The liquid was warm and there was a sweetness to the smell. And I was in heaven. I couldn't believe how much she came, but I was lost in the moment. I watched her face as she came, every sticky rope was accompanied by a moan and a look of excruciating pleasure. I wanted it. I wanted her to never stop. "Yes," I whispered as I ran my hands through the goo and continued to milk her cock, "give it to me."



She moaned and threw her head back. "Fuck!" Another torrent of cum sprayed across my neck.



My cock ached to be touched and I saw a huge dark spot in the fabric where it was pressed, but there was no time to think about my own orgasm. Helen was in the middle of hers. My hands squeezed and tugged. Helen writhed. Cum covered my shirt and pants.



When it was over, she leaned forward and kissed me like I had been gone for weeks. Our tongues moved back and forth into each other's mouths. The soft pillows of her breasts were pressed against my hand. And her cock was still throbbing and jerking.



I leaned down and ran my tongue along the nape of her neck. I let go of her penis and squeezed her breasts together. I ran her nipples across my open chest and the mess she had made.



And that's when I saw it for the first time, the shimmer. It was just for a second, maybe two, and it was faint, like faint enough that I wasn't sure it was real. I mean, it could have just been a trick of the light and we were both so high on what was happening. But I am sure that was the first time I noticed it, there was just a hint of blue along her shoulder, like a henna tattoo that's almost gone, but blue and in some strange pattern. But it was so faint, I didn't think I saw it.



We kissed again. And it took everything I had not to lower my head down on her cock.



It was so close, and I wanted to so bad. But I didn't. I didn't know how comfortable she was and besides she had just let go. Then I thought of her pussy, the glistening slit below her still rigid tissue.



"Here," Helen reached into my pants and wrapped her hands around my cock. "It's your turn," she bit my earlobe.



I did. No sooner had she gotten her fingers around my dick and I was spraying my ecstasy into the waistline of my khaki's. I couldn't help it. I don't know that I had ever been more turned on then I was right then. The entire experience had edged me for almost an hour. I was fuck drunk.







We kissed and fondled each other for another few minutes before I got up, got undressed, and got a damp towel for the both of us. After I got back into bed, we kind of both decided that it was time to talk.



"Are you still afraid?" I started. We were lying on our sides face to face.



"No, for some reason I'm not." Helen's cock had disappeared a few minutes after I had cum, it had simply slowly deflated and returned to a normal clit, little, and hooded in the shroud of skin. "Are you? I mean, you have to tell me what you're thinking." She tilted her head. "I'm serious."



It was her teacher face and I almost laughed. "Are you kidding me? I mean, Helen," I reached over and tucked a stray hair behind her ear. "I kind of got excited the first time it happened." I felt myself blush. Why was it so embarrassing, why did I hesitate to say it?



Helen looked at me for a second like she wasn't sure if I was telling the truth or not. "What do you mean?"



I swallowed. This was it. This was the moment where I told my wife that I was excited about the fact she suddenly had a penis. I took a breath and braced myself.



"I mean, when it first happened, I thought: Oh, that's interesting." Interesting wasn't the right word and I immediately regretted it.



"You mean..." she stopped herself like she wasn't sure she wanted to finish the question. "I mean, you aren't, like, worried?"



"Worried?" It was an honest question. I wasn't worried in the least that my wife had a twelve inch dick that was a solid three or four inches in diameter. I wasn't worried at all. I don't know exactly why I wasn't but the fact was - I was excited about it. But how do you say that without sounding crazy, right? "I mean, I would like to know what's going on, but if that's the way...I mean, if you are going to have a..." I didn't know what to call it. I hadn't thought about it – did she think of it as something different? What did she call it in her mind?



"A cock?"



I liked the hardness of the word when she said it. My own began to plump. Cock.



"Yeah," I tried to smile but it felt crooked, "you know what I mean. I love you and if you have a cock that's great, right?" I tried not to sound nervous, but I was terrified. I felt like I was walking on ice as thin as paper and that everything was going to break in the next sentence or two.



Helen took a second. She just sort of stared into my eyes like she was running over her response, making sure it was exactly what she wanted to say.



"Are you saying you like it?" Her voice was monotone and I couldn't tell what she wanted. Did she want me to be excited or did she want me to be weirded out? Which one was going to make her happy? I knew where I stood. But could I tell her?



"Yes," I looked down between us. Her breasts were half-covered by the blanket, the cleavage between them was dark and inviting. I thought of the way her penis could lay between them, how she could titty fuck herself anytime she wanted.



And then I realized that she hadn't said anything and I looked back up at her eyes.



"It's so strange," she sighed, "it's like I don't know how to feel about it, like there's a part of me that likes it." She looked down at mine and smiled. "I kind of always wondered what it would be like, and I only seem to have it when it's really, really," she paused and grinned, "enjoyable? Is that the word I want?"



I leaned against her. What was happening to us? How wonderful was this going to be?



"I mean, part of me wants it. Part of me really wants it, but that part is like a new part of me. Like a part of my personality that I didn't know I had. I don't really understand it. I just know that when it wants, I can't seem to ignore it. I give it what it wants?" She looked at me and shrugged. "Does any of that make any sense to you?"



I laid my hand over hers. "I think it does. The penis can't be the only change, right? There have to be some other physiological changes. It ejaculates like a regular penis, but you don't have the right...equipment." I was struggling but I did remember a fair amount about my junk from science class.



She scooted closer and I felt her nipple against my arm. It was hard and a little shiver went through me. I was so glad it was Friday. I had a feeling it was going to be a late night.



I kissed her softly. "I'm with you no matter what."



"Have you found anything that makes any sense of this though?" I could tell that part of her was still curious about the science of what was happening. Even if some part of her accepted it, she still wanted an answer. She had always had a keen sense of curiosity, she liked to understand things and how they worked.



"No," I scooted back a bit on the bed and looked her over. She was so beautiful. Her long legs and perfect thighs. "You?"



"No," she shook her head and kind of stared up at the ceiling. "What if it's one of the myths, like one of those stupid legends we keep stumbling over?" She looked at me seriously.



"Like the stories with magic and goddesses and stuff?" It was all either of us had found, a million websites devoted to futanari and transgender. I had spent hours on them, flipping through the main galleries of hentai and futa, reading the stories posted across the internet.



"What other explanation is there?"



I couldn't believe she was serious. She was a professor, a natural skeptic. She didn't believe in anything but art and science. And now she was talking about what if there was magic? But she was right. There wasn't a medical journal article ever written that described what was happening to Helen. Trust me, I had spent hours searching.



"I mean, we find new things all the time, right? And the Eastern religions and mythology, there has to be some validity to those legends, right?"



"I know what it sounds like, but I kind of just want a reason. I want to understand it, even if it's magic. I don't care, I just want to know."



"Magic," I chuckled, "That's exactly what that thing is," I looked under the blankets, "magic."



Helen threw the covers back and rolled on top of me. "Give me another hand job," she pressed her lips against mine and I felt her cock twitch to life.



***



I think it was Sunday morning, early. I woke up and felt Helen's cock against the small of my back. It wasn't fully erect, it was probably six or seven inches, plump but not hard. We were curled up in bed, her arm draped over me, her breath at the back of my neck.
