I should have headed to the first day of my new job at Dynamic Medical half an hour ago, but just getting out the door was proving far more difficult than I'd imagined. Sure, nothing was physically stopping me from going.
But when you have a trio of the hottest women on the planet all eager for your cock and a near limitless supply of stamina and what might be a limitless libido egging you on to breed them...well, you'd be a better man than I if you could resist it any better than I could.
"Mmmf...Charles, sir...you're so big...fuck! Oh my god, slow down, Daddy, or I'll...nnnngh...!!" At the moment, Mia was on the receiving end of my cock, yet another orgasm forced out of her. The petite blonde was pushed up against the wall, one flexible leg raised up to rest her ankle on my shoulder, her other on tiptoe because of the stark difference in our heights. Not the most practical position, but perfect for letting me slam into her with just as much power as I wanted.
Just a few days ago, Mia had been Mark, my good-for-nothing father. Thanks to the scientific breakthrough of a new kind of viral agent delivered via CRISPR-based gelatin capsules—I called them blue pills—he'd gone from being an overweight and balding man in his early 50s to the hottest piece of female jailbait I'd ever seen. She had the face of an angel, the perkiest B-cup breasts, a firm, round ass, and the tightest cunt I'd ever stuck my cock into.
Best of all though, her mind was mine to mold as I pleased. Originally, I'd made her think she was my daughter, taking a perverse thrill in hearing her call me Daddy. I still loved that, but the more I thought about it, the more I figured that could attract the wrong kind of attention.
So even if she was still calling me her Daddy while I fucked her brains out, in those addled brains, she was instead convinced that she was actually my little sister. Much easier to explain.
"Here it comes. I'm cumming. Gonna fucking breed you!" I squeezed down on Mia's throat, pushed my lips against her with a hard, firm kiss, my tongue dominating her mouth as fully as my cock was owning her womb, thick, sticky ropes of cum firing off deep inside of her.
I held her like that for a long moment, savoring it, my cock slowly relaxing enough that I could pull it out of her. Mia's legs gave out and she ended up on her knees. Her neck was marked red, her cheeks were wet with tears, and her head was rolling on her shoulders, her body totally exhausted.
"Mmm...big bro...you're so fucking good at that..." Mia said while looking up at me with the brightest, most pure smile I'd ever seen in my life.
So damn cute, I was thinking I might go for a round four.
"Master, may I?" Without waiting for permission, my maid Elle joined Mia on her knees, but she had her hands on my hips as she eagerly leaned forward and used her tongue to clean my cock.
Just like Mia, Elle had been transformed by the blue pill. Before, she'd been an out of shape drug addict, her body in even worse shape than my father's, but now she was...well, she was incredible. If Mia had the cutest, most doll-like face, then Elle looked like a goddess. High cheekbones, full lips, long eyelashes...and breasts big enough to fully wrap around and swallow my cock.
"Dibs on Mia's cunny!" My third girl, Kayla, exclaimed as she got on the floor and pushed her face between Mia's legs, lapping up at the cum oozing out like a puppy.
Kayla had been Mark's mistress, the secretary at his old job. She'd been a 7/10 before, but under the influence of the blue pill, everything about her was just better. A thicker ass, a waist that was tight and lacked the muffintop from before, and the largest breasts of my trio. Not to mention her luxurious waves of crimson red hair framing her gorgeous face with those emerald-green eyes.
Just looking down at my three women, my three slaves, I could feel my cock already getting harder. That was a side-effect of the medication I'd given myself. It differed from the one they'd taken: the blue pill formula was aggressive in the way it would repair damaged DNA, and left unchecked, it would "repair" an XY chromosome all the way into an XX chromosome, turning the subject fully female as it had done to Mia. The orange variant I had developed had gotten rid of that side-effect...with the new side-effect that it had nearly killed me.
But since I had survived, I'd reaped all the benefits for myself. I was bigger, stronger, more virile, a total alpha male with a chiseled jaw and biceps that could easily lift all three of my girls up on one arm.
And a sex drive that never turned off, it seemed.
"Nnf, Elle, you're too damn good at that. Get down on all fours so I can—"
Ding, dong.
Interrupting my little orgy was the doorbell. I exhaled sharply through my nostrils with annoyance, then glanced at the clock. I was late. No doubt that was Stephanie, my lab assistant and partner in crime, come to fetch me.
"Mia, go ahead and get that. You two, go ahead and wrap both of those sets of melons around my cock."
"Yes, Daddy," Mia said as she bounced out of the room to answer the door.
"Yes, Master," Elle said as she leaned in close to me.
"Love to!" Kayla wiped the cum from her chin and joined Elle in a heavenly double titjob.
Meanwhile, Mia unsteadily got to her feet like a newborn deer, then went to answer the door.
I put my hands on top of Elle and Kayla's heads, pulled them together so that they could lick the head of my cock together, their tongues intertwining lewdly as—
"Who the HELL are you?!"
That wasn't Stephanie at the door.
It was my Aunt. Her name was Rose, from my father's side of the family.
Aunt Rose was the only good thing about that side of the family. She was the one who encouraged me to get my degree in biochemical engineering. She'd helped me with tuition costs. She'd even helped me out when it came to getting my research position at my old campus and grant from NPC. I owed her more than I did any other person in the world for being where I was today.
She was my father's older sister, and though she kept herself in better shape than him, there was only so much that could be done to stop the passage of time. Her light blonde hair was now white, while her face had heavy lines at her cheeks and a bit of puffiness. Twenty years ago she had been a looker, but now she instead looked like a woman meant to be taken seriously more than anything.
Her seeing a half-naked Mia wasn't good.
I struggled to get my pants zipped up as quickly as I could, whispered to Elle and Kayla, "Stay here. There'd be even more questions if she saw you."
Then I headed out to greet her.
"Aunt Rose. What are you doing here?" I asked with a nervous smile that I hoped didn't look too guilty.
"And just who are you?" Her eyes were focused on me now, "...Charlie? Is that you?"
I smiled. I'd gained sixty pounds of muscle and had the body of a Hollywood superhero now, it wasn't a surprise she might not recognize me, "Yeah. I got really into...uh, the keto diet. And lifting. Lots of lifting."
"I see...then could you tell me who this tart is?"
"I told you...I'm Mia!" Mia said with a pout, stamping her foot on the floor, not something she should have done when she was only wearing a large t-shirt with nothing on underneath.
