The TV was still blaring news about the sexual zombie attack downtown. Shelia figures we best gear up and go fight.
"First, you two need to shower," Shelia said, looking at Heather and I, "but probably not together."
Heather and I looked sidelong at each other rather sheepishly. My midsection was a sticky, shiny mess with a (finally) deflated cock. Heather had wiped most of my cum off her face but it still clung to her tits and soaked her sports bra. She had been driven crazy with lust by my pheromone-laden pre-cum and jerked me off until I had erupted all over her. She'd then had a killer orgasm from my drug-enhanced cum being absorbed through her skin, all over her face and torso.
"Heather knows the way," Shelia, the smoking-hot scientist who was doing her best to keep her lab coat closed over her otherwise naked frame, said. "Run along now."
A minute later, Heather and I were walking in an embarrassed silence, side-by-side down a stark-white hallway towards the showers.
"That's never happened to me before," she ventured quietly, looking at me with a side-long glance. "I mean, I've, like, had one before, but never with another person. Do girls always..." she paused, blushing, "cum that hard with you?"
"This is new to me too," I managed to say, awkwardly. "These changes are coming on so quickly."
"Well, here's the guy's shower," she said, stopping by an open door and not meeting my eyes. "See you back at the lab," and with that she started to turn to walk down the hall again.
"Wait!", I said, "My names Rob."
"I like Bull better", she called over her shoulder as she continued down the hall.
I watched her walk away, mentally giving her ass and legs an A+. My cock started twitching slightly so I went into the deserted shower room before i got into any more awkward situations.
I peeled off my clothes to get into the shower when I caught sight of my body in the mirror. Not only was my cock way bigger than this morning and my nuts swinging like two baseballs, I was cut! I had abs, biceps and a wide chest. I'm pretty sure I'd grown a few inches taller as well.
I made a note to ask Shelia about these changes and went to clean off in the shower.
A few minutes later I was wearing just a towel, standing with Shelia and Heather back in the lab. Shelia had gotten back into her clothes after her romp in the showers with Deborah, and Heather was back in her jeans and a new sports bra she probably had in a locker. The wet hair look definitely worked for her.
"Your beach clothes won't do for saving the town," Shelia began. "You need something more, tactical." She opened a supply cupboard, taking out various items.
"Bull, and I do so love the name, you should wear this kit, designed for ranch hands who work around untamed male bovines. Kevlar-lined jeans protect against sharp hooves, with a quick-pull Velcro opening at the top for easy exits in case they get caught up on horns or fences when in a cage with a wild animal. It should work well for you to deploy your... engorged member."
I slid those on, soft & stretchy but looked like legit jeans.
"Now, a classic white T-shirt with our center's stylized logo in the center, a bull's head and horns."
"Both of you, take these black steel-toe combat boots and these black Kevlar vests With plenty of pockets and a few of the flash-bang grenades they use to stun bulls when they get out of control."
We got dressed, and looking down at myself, I've never looked so badass in my life.
Heather, with her jeans, boots, sports bra and vest didn't just look badass, she looked
fucking hot
. My cock started responding and I worked hard to calm down. It's a good thing these pants are designed to stretch.
"Don't I get a shirt?" Heather inquired.
"No, my dear," Shelia answered. "Bull here might need some, ah... inspiration, considering the fight we're dropping into, and your breasts are," Shelia fixed Heather with a smouldering look, "incredible. You should take these thin Kevlar gloves though, they won't restrict your judo skills."
Shelia led us out to the parking lot behind the centre.
"Here's our van, fully replete with the latest in veterinary field medicine and drone surveillance technology for tracking herds", she said. "Hop in."
Heather and I loaded in the back of the van while Shelia popped into the driver's seat, started the engine and peeled out of the lot, heading downtown into a zombie apocalypse.
"So, turns out my... package, isn't the only change to happen to me," I said.
"It appears that the more semen you produce, the more testosterone you will have in your body, and that increases your muscle mass," Shelia theorized. "The reason you look so cut is the fluid in your semen needs to come from somewhere, so your fat cells are all being raided to produce, ah... cum as you boys call it," she concluded.
Just then we approached the edge of downtown and saw our first sexual energy-draining zombie, a woman who's face was all grey, stumbling towards us with her arms outstretched.
"Heather! Take that one down and drag her into this van!" Shelia shouted.
"On it," Heather said with determination and kicked the rear doors open, hopped down and sprinted over to the zombie. She reached out her left hand above her head, snapped her fiangers which caused the woman to look up, then smoked her with a vicious right-cross to the chin, laying the zombie out cold.
"Holy shit," I thought, "that girl kicks ass".
Heather dragged the zombie over to the van and I helped lift it up onto the medic stretcher in the back. When either our bare arms touched the zombie woman's bare skin there were blue sparks and a slight feeling of being drained of something.
"Shelia, I don't feel so great," said Heather.
"Fascinating! Those sparks must be the zombie draining away your sexual energy," said Shelia as she moved to beside the zombie. "I surmise that your recent orgasm is providing some protection, but it will be limited."
I was staring at the zombie woman, who, now that her face was still and not a grimace of anger or horror, I realized she was probably a college student, likely a sorority girl by the Greek letters on her jacket. Kinda good looking, actually.
Just then the zombie woke up and grabbed at Heather with her left hand and Shelia with her right, contacting skin. Blue sparks were flying, and both women were stunned and groaning.
"Bull..." stammered Shelia, "pre-ejaculate... now!"
"I can't just do that on command!" I said, and grabbed the zombies hands trying to break their grip, blue sparks flying off my hands as well.
Shelia lunged over the zombie, tore it's coat off and ripped a button-down shirt open to expose a lacy bra over some luscious 32B tits. She one-handed the bra's front clasp (Shelia had skills in the bra department) and out popped a beautiful set of boobs.
The red haze crept into the side of my vision as my eyes zeroed in on those tits. My cock was pushing at the stretch fabric of my new jeans, so I tore the front flap open and out it sprang. I stepped one leg over the stretcher so I was straddling the sorority girl's stomach, and started stroking my cock.
In no time my cock started drooling pheromone-laden pre-cum all over the sorority girl's stomach. After dating a girl with a cum-phobia, I admit I'd suddenly had enough of being treated like cum was disgusting and I was driven by an overwhelming desire to soak this chick down with my pre-cum. I wanted to see her tits glistening and watch it pool in between them. I wanted to spurt my pre-cum all over her chin, cheeks and watch it run down the bridge of her nose. I wanted to fucking explode my cum all over her face and hair, I wanted...
"Bull! Stop, breathe deep!" Shelia shouted. "It worked!"
As I eased off the throttle I realized the effects had been instantaneous. The sorority girl coughed, let go of Heather and Shelia and tried to sit up. I stopped straddling her and sat, trying to calm down. My balls were aching for release.
"Where am I?" the girl asked, her complexion returning from grey to normal. "Last thing I remember was this nun with a grey face grabbing me."
"You're fine now," said Heather, who then fixed me with a predatory look. "Me on the other hand... I could make great use of that cock right now", and grabbed my vest in two hands, pulling me towards her.
"Heather, hold back," said Shelia, gasping. "These pheromones in such a small space, so strong! Bull overloaded and destroyed the negative energy sapping this, very hot, girl's sexual drive! Keep as aroused as possible to ward off zombie attacks or else they will drain you and you become one of them."
"Now if you'll excuse me, I'm going to see if this young lady would like to have sex with me," Shelia said. "Run along now! Go find that nun and take her out!"
As Shelia crawled on top of the hot sorority girl and they began to make out intensely, their faces smearing my pre-cum around, Heather breathed deeply and fought to centre herself while I stashed my cock away in my rancher jeans.
With an enormous effort, I turned my back on Shelia, who was wriggling out of her clothes. The red haze kept to a dull roar at the side of my vision.
"Time to go," I said as I went to open the back doors and snapped them right off their hinges. Wow, that was new. "Seems being horny has side benefits for me too," I said as I flexed my new muscles. "Let's find that nun."
Heather and I strode downtown, trying to stealthily avoid the zombies where we could and taking down individual ones where necessary, trying not to use too many of our flash-bangs.
"I want to fuck you so badly right now it's hard to think straight," Heather whispered as she scanned an intersection filled with zombies who were grabbing fleeing people, turning them into more of them. She held up her hands and you could see the occasional blue spark flicker off her.
"It's like an incredibly powerful zombie has some aura that is causing me to lose energy even without being touched," she said.
