I started as an experiment in artificial life using human tissue and DNA. They called me Shifter because they created a way to alter my body so I looked like someone else. What they were doing was both against the federation law and the Imperial law. The station we were on was the base station for a gene corp called New Horizons.

I had a dozen body types I could shift to and had to pick a new one each day. Trouble came in the form of an Imperial gene auditor and a Federation gene review group. They were doing a joint check on the company station. I was sixteen and was pulled out of bed in the middle of the night cycle.

My clothes and the personal items I had been given were shoved into a float carrier. I was led through the station with Dr Mapps pushing a personal comp into my hands, “Have a good life Shifter.”

He turned me and pushed me towards a crowded boarding tube going onto a liner. They had constantly told me that if anyone found out what I was or what I could do I would be killed. I had a ticket waiting for me in business class which was very comfortable. I was afraid and unsure as I went to the suite and unpacked my float carrier.

I hesitated and then went exploring and ended up on an upper deck with a high ceiling that had a holograph of the stars outside the liner. The information I had found said the station was just a brief stop in the system before leaving. I sat beside a clear pool and leaned back before reaching back to unbraid my hair.

A girl giggled from beside me and I turned to look at her. I froze when I saw her naked body, she looked like she was in her early teens. Another was just beyond her and was a little older. Beyond her was a young looking woman and then two more slightly older teens. They were all nude and I looked around to see several more around the pool.

The first girl moved closer, “this is a clothing optional pool.”

I looked up from her perfect nipples and then at her mother who smiled, “need help with your hair?”

I shifted uncomfortably before nodding, “yes.”

She nodded, “help him Taz.”

The girl grinned as she came to sit on the lounger with me and I sat up. She turned me and started upbraiding my hair, “your hair is very soft.”

When she finished she ran her fingers through my hair, “need help undressing too?”

I reddened and stood before slowly undressing and folding my clothes. She gasped when she saw my hard cock and I reddened even more. I turned away and sat again and before I could think of something to say she straddled me and rubbed her pussy on my cock, “you have a big beautiful cock.”

I looked at her nipples and she giggled as the girl that was slightly older came to sit beside me. She bent to suck on her sister’s nipple before grinning at me as her sister shuddered, “the horny little slut has been waiting for a proper guy to fuck.”

I looked up from her nipples and she grinned, “we all are.”

I looked around as their mother smiled while watching us and the other two lay half on her watching me, “I have never...”

Taz laughed and rubbed back and forth on my cock again, “do you want to?”

I bit my lip as I tried to think of a way to explain without giving myself away. Taz stopped and lay on me, “you want to, I can feel you but you are afraid.”

Her sister cleared her throat but Taz ignored her, “quiet Candy.”

It slipped out, all these years and it just slipped out, “I’m a Genie.”

I looked at her with wide eyes as their mother moved towards us. Taz touched my face, “so?”

I reddened and looked away, “I’m not real like you.”

She wiggled, “buster you are as real as they come.”

She pushed her mother’s hand away, “stay out of it Beth.”

I turned to look at her and then at Taz, “they made me in a lab from DNA and...”

She touched my lips, “you are engineered, I heard. Guess what, a lot of people are.”

I looked at her in surprise and she sighed, “people normally have their sperm or egg checked and corrected. If that isn’t engineered I don’t know what is.”

I looked at the other two girls as they joined us, “but they made me so I could change what I looked like.”

Taz grinned, “that would be cool.”

She wiggled, “what is your name?”

I looked at her and her sisters before looking at her mom, “Shifter.”

She laughed, “of course.”

She sat up and rubbed her pussy, “well I’m Taz and my sisters are Candy, Smoke and Grace. My mom is Beth and she is a gene engineer that made us.”

Beth snorted, “I harvested the sperm personally so I didn’t do it by myself.”

The girls grinned as Taz rubbed the head of my drooling cock, “who is your guardian?”

I looked at them, “I don’t know... I... they put me on this ship and said to... have a good life.”

Beth hissed, “cowards.”

Candy swatted at her, “blame them later.”

Taz nodded, “so you are alone.”

She looked around before lifting and moving my cock and pushing down and shoving my cock into her tight pussy. She shuddered and looked at her mother, “his cock is really stretching my pussy.”

I closed my eyes and groaned at the feel of her warm pussy around my cock. I could almost feel her heart beat as she sat there. Candy rubbed my chest, “you can stay with us and fuck us if you want.”

I opened my eyes and looked at Taz as she wiggled and shifted while her pussy kept grasping my cock. I took a breath and thought about my hair and changed the color. They were silent but Taz suddenly grinned, “that was cool. Your hair contrasts better with mine now.”

I smiled and reached up to cup her beautiful breasts, “you are nice.”

She bent to kiss me before starting to rock, “what else did they do?”

I shuddered at the feel of her pussy and dropped my hands to her hips, “besides shifting shape?”

She spasmed hard and moaned and Beth leaned over to suck on a nipple, “yes besides that.”

I started to lift my hips and thrust into Taz, “My body regenerate very quicky.”

Candy and Grace moved to hold Taz as she twisted and convulsed while her pussy kept gripping my cock. I jerked and thrust up as my cock erupted suddenly. I peed a fountain of cum through her cervix and she started to scream as her mother covered her mouth. I shook as her tight pussy kept milking sperm out of my cock.

When I was done I relaxed and sighed as Taz slumped and then laid on me, “oh man, that was better than the sim.”

Her sisters laughed as her mother chuckled and lifted her hips, “we better take this to our suite.”

I shuddered when my cock came out of Taz and Smoke giggled before bending to lick the cum off my cock. I groaned and they laughed before helping Taz up and then Beth pulled me up. Candy grabbed my clothes and Taz took my hand, “thank you Shifter.”

I had been trying to think of what to say and blinked, “but... I... wanted to thank you.”

She grinned and pressed against me and gave me a passionate kiss. The large suite we went to had a large central room and four bedrooms off it. Taz grinned as she looked around, “Candy and I were sharing.”

The other girls grinned and Grace pressed against me, “maybe we can put all the beds in here and share you.”

I blushed as they laughed and Beth turned my face, “you are safe with us.”

Taz grinned, “take Grace to her bed and fuck her while we move things around.”

I looked at her and then at Grace as she began to pull me after her. The bed wasn’t large but it was big enough I guess. She turned me at the bed and caressed my chest, “lick my pussy first?”

I smiled as I looked down and then back into her face before nodding. She laid back on the edge of the bed and I knelt while she spread her legs. I looked at her pretty pussy and leaned in to lick through her slit. She had a hint of berries that I liked and I pushed my tongue into her before I nibbled.

As she shuddered and moaned I captured her clit and used my tongue on it while sucking. She humped and jerked as I kept it up and moved back and forth between licking her, pushing my tongue into her and teasing her clit. It was a few minutes before she began to wail and spasm jerkily, “aaahhhh!”

She covered her pussy and I looked up as she wiggled back into the center of the bed. I stood and she held her arms out as she panted. I moved onto the bed and between her legs before pushing into her slowly. She groaned as her tight pussy squeezed and I sank into her deeper. She put her arms around me as she began to hump and I started to fuck her.

I used long thrusts that hit the back of her pussy and pushed. She began to howl a couple of minutes later as she jerked and thrashed around. I buried my cock so I could feel her warm pussy around my cock and started to hump and jab with short thrusts. Grace lifted and spread her legs as she convulsed while her wonderful pussy went to work massaging my cock.

I started to kiss her as she struggled and a minute later she was yelling and screaming as her pussy tightened almost painfully. I had to move more and began to fuck her a little harder with deep thrusts. The others sat on the bed but I felt my balls churning again and didn’t stop. Grace was thrusting up each time I pushed her cervix open.

I finally shoved all the way into her and kissed her. She spread her legs extremely wide as I peed warm sperm through her cervix, “yyyeeeessssss!”

I was shaking and shuddering as I pumped huge spurts into her and held her tight while kissing her. It was awhile before I was done and lay on her as we caught our breath. Taz rubbed my butt, “pull out.”

I looked at her and then at the others before looking at Grace as her pussy continued to grasp and squeeze. She grinned and hugged me, “its okay.”

I nodded and pulled out reluctantly before starting to move away. Beth laughed as she reached between her daughter’s legs to rub her leaking pussy, “he put a lot of sperm in you?”

Grace smiled in satisfaction, “just enough.”

I looked at them as they laughed and Candy crawled onto me as she pushed me back, “so when you regenerate does that include your sperm production?”

I blinked and shrugged, “I don’t know.”

She grinned at the others, “we should find out.”

Taz laughed as she bent to kiss me, “want to eat first?”

I hesitated as I looked at them and my stomach growled. Beth laughed as the girls giggled and pulled Candy off, “let him eat before you try to drain him.”

Taz slipped her hand into mine and I looked at her before smiling and holding it. We had to get dressed before they pulled me through the ship and into a dinning area. It was while we were eating that the ship announced that it was leaving the station. I looked around but Taz scooted closer and leaned against me, “its okay.”

I looked at her before nodding and going back to the large meal on my plate. Beth was across from me and smiled, “do you always eat that much?”

I reddened, “It’s the shifting and if I have to regenerate it is worse.”

She nodded, “That makes sense. Did they hurt you to make you regenerate?”

I looked down as I remembered the pain, “sometimes.”

Taz bumped me, “no pain now. We are just going to drain your balls and see if...”

The other girls laughed as I smiled at her. After eating they pulled me around the huge ship to look at anything and everything. They kept me distracted the whole time and finally we closed the door to their suite. The center room had two large beds pushed together in the center of the room.

Beth smiled as she began to undress, “good, they were able to do what I asked.”

The girls grinned as they began stripping and Taz turned me before undressing me slowly, “Candy likes it doggystyle so after you lick her roll her over and lift her hips.”

I looked at her sister and she grinned, “long deep strokes.”

They laughed and I smiled, “after I lick you.”

She laughed and backed onto the bed, “yeah, after you lick me.”

Taz pushed me, “I get to sleep on you after everyone gets a turn.”

I smiled at the thought and moved onto the bed after Candy. She was laid back with her legs spread and I leaned down to look at and smell before licking her pussy. She sighed and shivered as her hips lifted, “finally.”

Beth laughed as she laid beside us, “pour baby only got to experience this in a sim.”

Candy smiled but didn’t respond as Grace crawled onto her mother, “hush and let her enjoy him.”

I licked and pushed my tongue into her before nibbling and then sucking on her clit. She shuddered and thrust her hips up, “ooohhh!”

I kept licking her and wiggling my tongue but went back and forth, pushing my tongue into her. She began to breath harder and shake as she hump up and moaned. It was several minutes before she wailed and spasmed as she twisted and pushed my face away, “aaaahhhh!”

I looked up as Smoke and Taz giggled and moved before helping Candy roll onto her stomach. I lifted her hips and spread her knees wide as I moved up between them. I felt her warm pussy and shifted and slowly sank my cock into her. She shuddered and pushed back to get my cock deeper and I held her as I started to fuck her with deep strokes.

Her pussy was almost hot and very tight as my cock stretched her. She sighed and moaned and kept pushing back as I fucked into her. It took a couple of minutes for her to shudder and then she went wild. She wailed and twisted and kept slamming back onto my cock while her pussy grasped and tightened, “aaaahhhh!”

I tried to hold her hips but she writhed around so much it was hard. Grace pushed me down so I was on Candy with her hips tilted. She started kicking the bed as I fucked her hard and deep. She howled and thrashed while wetting me and the bed, “oooohhhh!”

I continued to fuck her with long strokes as she jerked and spasmed. It was a long time before I pushed into her shaking body and tried to go deeper as I peed cum. Candy shuddered as her pussy clenched and started milking my cock, “MOMMA!”

I shivered and grunted as I kept spurting and pumping sperm into her and Beth moved to caress her daughter’s bare shoulder. When I stopped cumming Candy sighed and I pulled out and moved to lay beside her, “you okay?”

She turned her head and grinned, “In heaven.”

Her sisters laughed and Taz crawled onto me and kissed me, “need a break?”

I caressed her hips and sides and shook my head. She kissed me and looked at her sisters, “Smoke likes it on top.”

I looked at the one sister I hadn’t had sex with and she grinned, “cowgirl.”

I smiled as Taz moved off me and Smoke came to straddle me and lift up. She wiggle down my cock, “you can play with my titties.”

I grinned and reached out to cup them before starting to knead them and rub the nipples. She wiggled and rubbed her pussy on me before starting to rock. Her tight pussy grasped and squeezed my cock as she began to bounce and twist while moaning louder, “mmmm!”

I tugged on her nipples and she started convulsing as her pussy spasmed and became a lot wetter, “fuck!”

The other girls laughed as she thrust back and forth almost desperately. She began to roll her hips while her pussy grasped and tried to milk my cock. I held her waist and began to thrust up into her and she started wailing and howling, “aaaahhhhh!”

She was completely incoherent as she fell onto me and I rolled before fucking into her with long thrusts. She was bucking and thrashing around as I fucked her slowly but with long thrusts and began to grind. She kept wailing and clutching me as she wet me every other minute until I finally pushed into her and held her tight.

She tilted her hips and grunted when I pumped the huge spurt of cum against her cervix, “YES!”

I spurted again and again until I was done while Smoke panted and hugged me. I looked into her face to see her eyes closed but she had a smile on her face. I gave her a kiss before I pulled out and moved to lay beside her. Beth moved around until she as laying beside me, “nice and slow while I am on my back.”

Taz giggled, “do her Shifter.”

I turned to feel and caress Beth’s body and bent to kiss and then suck on a nipple. She shuddered and moaned as I moved over her and kissed her. I slowly sank my cock into her tight pussy. She spread her legs as she lifted them and I began to fuck her with long thrusts while still kissing her.

She sighed and hugged me while her pussy rippled and kept grasping my cock. It wasn’t long before I was burying my cock and pressing against the back of her pussy. She jerked and shook harder as I fucked her steadily while kissing her. Her pussy was squeezing my cock and tightening each time I pushed into her.

She was moaning and began to writhe around and hump up harder. I buried my cock and began to jab and grind. Beth spasmed and screamed as she wet me and clung to me. She started thrashing around and bucking as I went back to fucking her with long thrusts. I would press and grind each time I pushed into her and it wasn’t long before she howled and convulsed.

She struggled and kept jerking and shuddering hard as I finally began to fuck her long, hard and deep. She was constantly wetting me as she spread her legs wider and her pussy was gripping my cock. I lasted several minutes longer before I shoved into her and tried to push deeper as I pumped and spewed cum.

She screamed as I grunted and spurted again and again to pump sperm through and into her womb. She jerked with each spurt of cum and hugged me as her pussy milked my throbbing cock. When I was done I hesitated before pulling out. Taz pulled me onto my back and straddled me before impaling her pussy and laying on me.

She gave me a kiss and put her head on my shoulder, “perfect Shifter.”

I hesitated before hugging her and slowly relaxing. Some days I would fuck them ten times and some days just a few. Taz was with me constantly and led me off the ship when it reached their home. That was years ago and before I got each of them pregnant, including Beth. We work together now and I became a gene engineer like Beth.

Taz is still my constant companion but the other girls are also my lovers.
