Lieutenant Elaine Seabrook

“You are not going anywhere, alien!” I cried, holding the dickgirl-slime to me, her massive cock buried in my pussy, all that DNA filling my teat. “You are the property of the US Government.”

“Rurururururu?” she asked in that strange language. There was a smile on her lips. A smirk. The world grew dark.

“What?” I gasped, fighting to stay conscious. I squeezed her to my naked body, her breasts spilling over mine. I compressed her gelatinous body. “What did you do to me?”

“Rurururururu! Rururu! Rurururururururururu!”

It made no sense. Something was wrong. I was so tired. Everything swam around me. My mind swirled. I had to keep conscious. I had to fight against this drowsiness. I blinked my eyes and shook my head. But I had been up so long.

“No, no, not again!” I gasped. “This isn’t happening to me again! What have you done to me? What have you ... done ... to...” My words slurred. It grew so hard to think. The world swam around me. It was growing so dark. It pulled me down and down into the shadows. “You can’t ... I ... I ... I will ... hunt you ... down...”

“Rururururu?” She smiled at me. I stared at that smirk on her lips then...

BEEP! BEEP! BEEP!

The rhythmic beeping sound reached through the darkness. I groaned, rising out of sleep. I fluttered my eyes. I felt so weak. So exhausted.

BEEP! BEEP! BEEP!

That sound drew me out of this heaviness crushing me. I fluttered my eyes.

BEEP! BEEP! BEEP!

My eyes opened. I was laying in a bed. I felt something in my arm. An IV led to a saline drip. There were EKG sensors on my chest leading to the machine monitoring my vitals. I was in a hospital. Of course, I was in a hospital. I came here because ... because...

The alien.

Pink. Slime. Smirking. She had a cock. She fucked me with it.

“You’re awake,” a pleasant woman said. A nurse with auburn hair and blue eyes set in a motherly face. “I’m Nurse Nora, Lieutenant Seabrook. You gave us quite the scare.”

“Scare?” I frowned, struggling to think. I had come to the hospital to chase the alien. “Where is she?”

“She?” the nurse asked, arching an eyebrow.

“The alien?”

A smile split her lips for a moment. “Alien? What alien?”

“The one with the dick that ... that ... violated me!” I gasped, sitting up. I wore a hospital gown. The sensors on my chest pulled on the lead, the sticky tape biting at my skin. I fell back. “What happened to me?”

“You passed out in the middle of the hospital,” said the nurse. “Ranting about some alien making Danielle Seymour into a woman. I mean, she was a woman.”

“She used to be a man, right?”

“Before she transitioned,” said the nurse, shaking her head. “You were dehydrated and exhausted. How long did you go without sleep?”

“I ... I don’t know,” I said. “I was drinking lots of coffee.”

“Caffeine leads to dehydration,” she said, nodding. “You pushed yourself too hard. I’ll let your commanding officer know you’re recovered.”

“But the alien...” I whimpered.

The nurse laughed again and headed out the door. My cheeks burned. There had to be an alien, right? I hadn’t dreamed that. She had a dick and she fucked me.

Colonel Powers came in a moment later in his uniform. He stared at me, shaking his head. “I heard about your rant.”

“Rant?” I asked, my heart quivering.

“Seems you had a mental breakdown.” He sighed. “Something about aliens turning a man into a woman.”

“Wasn’t he a man?”

“Yes, weeks ago,” said the colonel. “I saw the medical records. Had the surgery performed to transition. Well, mostly. There’s still some ... er...” He swallowed. “Well, it doesn’t matter, he—she!—is not something an alien did. You just ... got overworked.”

“Overworked?” I swallowed. “But I was tracking something from space.”

“Something, yes,” said the general. “Something entered the atmosphere. We think it burned up. At the speed, it was going and the size, it wouldn’t have survived. We’re just lucky it was a small extrasolar object. If it was much bigger, it would have caused damage. One in a trillion chance that it hit us. A fluke. Not alien.”

“But she ... she was in here. She was pink and made of slime.”

“A dream,” he said. “Or a hallucination. You’re ... injured. Overworked. It happens. You’re on medical leave.”

“Okay,” I said, so confused. I felt like I had been so close, but ... She looked so human. Only made of slime. It was surreal. It felt so real. And she had this big dick that made me cum really hard. A good cum. I still felt good.

“They want to hold you overnight,” the colonel said. “Get some sleep, lieutenant. You’ll be on two weeks medical leave. You’ll have to speak to some counselors. Make sure there’s no underlying problem.”

“I’m not crazy,” I protested. “I just...” I swallowed. “I guess I had been working hard.”

“You have to remember to take care of yourself,” he said, nodding. “I’ll see you in a few days. Check in on you.”

“Yeah,” I said and leaned back against my pillow. Just ... overworked? I guess that made sense. It was a shame. She felt so ... so...

Amazing.

As Nurse Nora came back to check on me, I closed my eyes and fell into dreams of a pink slime with a huge dick fucking me so hard.


Shannon Mathers

I squirmed with Ruru in my pussy. The hospital was back to normal. Everyone was acting like they were supposed to. The Seymours thought that it was natural that they were both women, though one had a big dick.

It was a shame she had to forget all about our fun today.

Morgan and Mommy Stephanie were sitting with me in a waiting room. The colonel strode by without giving us a second glance. Why would he? We were just a family waiting in a hospital. It was such a commonplace image.

“I hope this worked,” Ruru said in my pussy sending a naughty tingle rushing through my body.

“Yeah, me, too,” I said.

Then Mommy Nora, my other futa-mother, appeared. She wore her pink scrubs and rushed over to us. She looked so happy. The three of us bounded to our feet and embraced her, squeezing her tight as my pussy clenched tight around Ruru.

“Your heartbeat just went up as you stood,” Ruru gasped. “Is it good news or bad news?”

“Good news,” I said in delight. “It worked, Ruru. It worked.”

“Yes, it did,” Mommy Nora said. “The colonel bought that Danielle Seymour had a sex change a few weeks ago, though she hadn’t had her penis removed. My little addition. He also believes that Lieutenant Seabrook had a nervous breakdown from dehydration and lack of sleep. Her behavior today, from what I gleaned, had been a little ... erratic.”

“I’m safe?” asked Ruru.

“She’s safe?” I asked, my heart beating fast.

“The colonel seems to think that Ruru was just some extrasolar asteroid that burned up on re-entry. That she never landed.” Mommy Nora smiled. “No one is looking for her!”

Morgan whooped in delight. My pussy clenched down on the futa-slime as tears gathered in my eyes. I held my two mothers and my little sister tight. Then the four of us met for a naughty, incestuous, four-way kiss. It was a wonderful delight. Such passion swept through me.

“We have got to celebrate,” Mommy Nora said. “Let’s get home. Ooh, maybe Kylie is awake. I very much want to make love to my new daughter.”

“Me, too,” Mommy Stephanie said, this wicked twinkle in her eye. “We have quite a few daughters we have to share.”

“Yes, we do,” Mommy Nora said.


Nora Mathers

I was flying high. My job was safe, I had a futa-dick, a hot futa-wife, two sexy futa-daughters, and a gender-swapped daughter to love. Plus Ruru. And Kaylani, from what I had gathered. Kylie’s girlfriend was into all of this.

“Mmm, let’s go, Mommy,” Morgan said. She was riding in my car. We couldn’t go home in the same vehicle or one of them would be left behind.

I glanced at my youngest daughter. Fourteen and with a wicked smile on her lips. “You’re going to suck my futa-dick as I drive,” I said, already unknotting my scrub bottoms and letting my clit grow. “That’s just wicked of you, Morgan. Just wicked. I can’t believe you would do something unsafe.”

“Then why are you shoving your bottoms down and growing your clit-dick, Mommy?” she cooed.

“I don’t know what you’re talking about,” I said and looked down at my futa-dick thrusting up to my steering wheel. “How did that get out?”

“I don’t know,” my futa-daughter purred. Morgan ducked down and suckled the crown of my girl-cock into her hungry mouth.

I groaned as she suckled on my mommy-dick. I shuddered and backed up my car in the parking garage. People were moving around, heading home or coming to the hospital. I had my naughty daughter bobbing her head.

She worked her mouth up and down my cock, sucking with just such passion on my girl-dick. She nursed with hunger on me. I groaned, savoring every moment of her hot mouth bobbing up and down my futa-dick.

My pussy clenched. My ovaries drank in the incestuous delight of my futa-daughter’s hot mouth. She suckled with passion. I loved the taboo thrill of being suckled on by her in public. I approached the gate guard, going for the automatic ones where I could use my pass.

My futa-daughter suckled with such wild abandon. She held nothing back as she worshiped me. It was an amazing delight. I groaned, loving this wonderful moment. I shuddered, my back arching as she suckled with such rapture.

I groaned, my heart racing as I waved my pass before the sensor at the gate.

The guard in the booth two spots over waved at me.

I waved back, trying not to show the pleasure on my face. My futa-daughter suckled with such wanton delight on my mommy-cock. She loved it as the arm rose, bending in the middle to lift over my car. I drove through and out onto the street. My heart beat so fast as my orgasm rose.

Then her hand shoved into my scrub bottoms. Her fingers parted my curls and found the wet folds of my pussy. The naughty minx stroked my cuntlips as I turned towards the freeway. My hands gripped the steering wheel as the naughty Morgan nursed hard.

“You little scamp,” I whimpered as she swirled her tongue around the crown of my dick.

She suckled hard and nipped my shaft with her teeth., though not hard.

“Morgan Mathers!” I gasped as she did that. “You wicked, little daughter!”

She giggled around my cock and suckled again.

I shuddered, slowing for the light by the freeway on-ramp. She thrust her fingers into my cunt. My back arched. Her fingers filled my cunt. I groaned at how amazing that felt. She had such long digits. They worked in and out of my pussy as she suckled on my cock.

The light turned green.

I accelerated as I made the turn onto the on-ramp. I head up it, going faster and faster as my futa-daughter bobbed her head. She worked her mouth up and down my cock. I loved it. My pussy clenched around her fingers. The pleasure swelled in me.

I hit sixty mile per hours and kept accelerating. I glanced over my shoulder, signaling for the merge. I found a spot and slid into it while Morgan suckled on my cock. The ache built at the tip of my dick. I groaned, focusing on driving.

This was so insane.

“Yes, yes, yes,” I moaned as I hurtled down the freeway, my futa-daughter sucking hard. “Morgan!”

My mommy-cock throbbed in her mouth. Her fingers thrust into my pussy, churning up the hole that had birthed her. My orgasm built faster and faster. My ovaries brimmed with all the cum that would fire into her naughty mouth.

My sweaty palms clutched at the steering wheel as she kept suckling at me. She nursed with such passion on my cock. I groaned, my head tossing from side to side. It was an amazing delight to have her sucking so hard.

I shuddered, my face contorting with building pressure. She jammed her fingers into my cunt and suckled hard. My back arched with the pleasure of this moment. My ovaries burst with the pressure. I erupted.

“Morgan!” I squealed.

Stars danced before my eyes as I pumped blast after blast of cum into my futa-daughter’s mouth. She squealed and gulped down my cum. She swallowed it with hunger. I loved the way she gulped that jizz down. She swallowed it all.

“Yes, yes, yes,” I gasped, my body bucking.

My pussy convulsed around her fingers. I bucked, my cunt sending bliss flooding through my body. Euphoria rushed from my cunt. It washed over my mind. That delicious pleasure flowed over my thoughts.

I trembled, my orgasm hitting that wonderful peak as I...

Drove at ninety down the freeway.

“Shit!” I gasped and let off the accelerator, firing the last blast of cum into my daughter’s mouth. I panted as I slowed to eight and down to a reasonable seventy. I looked back in the rearview mirror. No red lights flashed behind me.

I let out a sigh, my body trembling with the delight. That was so insane.

Morgan slid her mouth off my cock and her fingers out of my twat. She leaned back in her seat and suckled my pussy juices off her fingers. She trembled as she did that, her futa-cock tenting the front of her skirt.

“Buckle up,” I told her.

She rolled her eyes. “Yes, Mom.”

She grabbed her seatbelt and pulled it on, buckling it up. I breathed in a sigh of relief. That was so dumb. This futa-cock made making rational decisions hard. Just like it made me act when I got horny, then I was seducing new mothers and fucking my sister in a hospital room.

I had to be more careful. But it was a lot of fun being a futa.


Shannon Mathers

“Wow, Mommy Nora is driving fast,” I said, my pussy clenching down on Ruru.

“Eager to get home?” Mommy Stephanie asked, glancing at me.

“Maybe,” I said. “Don’t lose her. I want to be the first one to fuck Kylie. That will be so hot.”

“Why not me?” Ruru asked. “I made him into a her. She’s only a girl because of my amazing cum.”

“Tag-team her?” I asked.

“Yes!” Ruru gasped.

“Step on it, Mommy,” I groaned, glancing at Mommy Stephanie. “We have to beat them home. Ruru and I are going to make love to Kylie first.”

“What’s in it for me?” asked my gender-swapped futa-mother.

“A yummy creampie,” I said. “Mmm, all our cum licked out of Kylie’s new pussy.”

“I’m stepping on it,” groaned Mommy Stephanie.


Kylie Mathers

I felt something warm around my face. Boobs. Big, soft boobs. I groaned, snuggling into them. I hugged the woman in my bed. Kaylani? It felt like Kaylani. My sexy, Hawaiian girlfriend. The cheerleader’s big and perfect boobs felt amazing around me.

My dick...

My dick wasn’t hard.

Instead, I felt this wet slick between my thighs. I groaned, shifting around. My nipples rubbed into Kaylani’s stomach. I gasped at how sensitive they were. They shot down to that wet ache between my thighs. I groaned, something clenching.

A hole I never had before. I shifted, my chest jiggling.

Jiggling...?

“Mmm, morning, Kylie,” purred Kaylani. “You’re starting to wake up.”

Kylie!

I gasped and bolted up, ripping my face from between my girlfriend’s big boobs. My tits heaved beneath me. They bounced and quivered. I stared at them. My nipples were fatter and thicker. I groaned, feeling long, brown hair dancing over my shoulders.

I thrust my hand between my thighs and felt no cock. Instead I found a thick bush and a wet slit. A pussy. I was a woman now. I groaned and fell back on my pillow. I rubbed at my cunt in delight, sliding my fingers up and down it.

Kaylani lay on her side, her big boobs jiggling together. She had this hot look in her eyes as she stroked her golden-brown hand between my pale boobs. She made me shiver with her touch. She was such a sexy girlfriend.

“Mmm, Ruru did it,” I said. “I’m a girl.”

“You’re a sexy girl,” moaned Kaylani. “I just want to go down on you and—”

The door burst open and Shannon flew in. My sister was ripping off her dress while from between her thighs spilled something pink. Ruru fell out of her pussy and landed in a large blob on the ground. Shannon’s round boobs jiggled, her red hair flying.

“No, no, I’m going to fuck our new sister first!” Morgan shouted from outside the room.

“Sorry, Ruru and I beat you,” Shannon cried, her futa-dick swelling from our shaved pussy.

Beside her, Ruru grew into a clone of Shannon made of pink gelatin. Her body jiggled as she formed pigtails like Morgan wore. Her face, wearing an identical look of lust and delight to Shannon’s, stared right at me.

“Ruru and I are going to fuck you so hard, Kylie,” my futa-sister said, her girl-dick thrusting from her shaved pussy. “How does that sound?”

“Amazing,” I moaned.

“I’ll go take care of Morgan,” said Kaylani. She kissed me. I trembled as my soft lips kissed my girlfriend’s. We were both women now. This was so hot.

She broke the kiss and rolled off the bed. I trembled as her golden-brown ass swayed towards the door. She snagged my little sister and pulled her off. Morgan protested, but not that hard. I bet Kaylani had grabbed that little slut by her girl-dick.

Shannon and Ruru flowed into the room as our two futa-mothers stood in the doorway watching. This was so wild. The futa-slime slid onto the bed before me. They would sandwich me the way a slut deserved.

I was a slut now. A naughty, whorish girl that would have so much fun with her new pussy.

“Mmm, Kylie,” Ruru moaned. “We’re going to have so much fun, aren’t we?”

“Yes, we are,” I panted, so ready for all the fun to happen. It would be amazing. Just the best thing in the world to have their girl-dicks fucking me.

Shannon moved in from behind me. A dick in my ass and pussy. That was so hot. And one of them would be my futa-sister’s. This was so wild. Ruru stretched out on her side, her face so cute. She cupped my face and kissed me.

I groaned as her round breasts pressed against my larger tits. I shuddered at how nice that felt. She kissed me with hunger as her futa-cock nuzzled into my stomach. I grabbed her shaft and shoved it down my body. I was so ready for her to fuck me. I wanted it so much.

I nuzzled her into my pussy. She rubbed into my pussy lips. A wave of heat shot through me at the feeling of her girl-cock pushing against me. This wave of heat rushed through my body as she entered me. My cuntlips spread around her thick shaft.

I whimpered into her kiss.

It was so amazing to have a futa’s cock entering my pussy. Just a treat. This was something that I had wanted to experience for such a long time. I was so eager for this delight. I wanted that big dick to make me squeal. I would cum so hard.

Ruru’s thick futa-shaft stretched me out. This was all my fantasies come to life. Being fucked by a futa. Being a girl with a huge cock in me. I groaned as Ruru’s big dick bottomed out in me. I trembled in delight, loving this heat. It was amazing.

Then Shannon pressed into me from behind. My sister’s tits rubbed on my back, her nipples hard. They felt so wonderful against me as I kissed Ruru. My tongue danced with hers as Shannon slid her futa-dick down my spine and into my butt-crack.

I clenched my pussy down on Ruru’s thick shaft. What a way to lose my girl-cherry! A futa-dick in my cunt and asshole.

The tip of Shannon’s futa-cock slid down to my asshole then kept going. I broke the kiss with Ruru as she nuzzled into my pussy lips stuffed with Ruru’s big cock. What was Shannon doing? Did they both wanted to have their dicks in my pussy at the same time?

“Shannon?” I gasped as she pushed against me.

“Don’t worry,” Shannon purred. “Ruru’s cock is going to compress and...” She thrust and popped into my cunt. “See?”

“Holy shit!” I gasped, spasming between my futa-sister and the futa-slime.

My boobs rubbed into Ruru’s as Shannon’s girl-cock sank deeper and deeper into my bowels. I trembled as she sank to the hilt in me. It was such a thrill to have her filling me up. I groaned, loving the way her girl-dick stretched me out. It was an amazing rush to have them both inside me.

My pussy clenched down on the two futa-dicks. It was a thrill. A pure delight to have them squeezing about me. I shuddered, trembling at the feel of them both in me. Then I groaned as Shannon drew back.
