Fifteen minutes later after becoming uncomfortably aroused by the moans coming from Molly’s room I decided it was time to head out. I wandered around Campus a bit in the general direction of the Phi Kappa Fum while I sorted out my plan. By the time I got to the door of the imposing structure it had just started to get dark. I knocked, silently praying Kate was not around.

Luckily, another girl opened the door. “Can I help you?” she said.

“I’m here for Priscilla. She is expecting me.” Little white lie one, I thought, starting a tally. 

“Okay, come on in.” She lead me into the foyer and back towards the stairs before turning. “Can I ask you to wait here?”

“Sure,” I shrugged. The girl walked up the stairs and out of sight and I turned to glance around at the sorority’s decadently decorated interior. Seeing it a second time I couldn’t help but feel it was a bit garish. It was the kind of place someone with too much money and very little taste would make. I was trying to guesstimate the cost of the marble statue at the center of the room when Priscilla’s voice startled me.

“Couldn’t stay away I see,” she purred.

“Heh,” I laughed nervously. “I guess not.” I turned and saw an even more revealing dress than the night before. Despite having grown a few inches it appeared to be perfectly tailored to her increased height. A slash at the hip left a scandalous amount of thigh exposed in a fashion I vaguely recognized as oriental. The dress was a bit snug around the bust, I thought, unable to prevent myself from stealing a glance at the large orbs jutting to either side of her cleavage filled v-neck. I noticed a slight humming sound, but Priscilla started talking again before I could identify its source.

“Want to come up to my room?” She offered with a smile. Danger! Danger Will Robinson! I needed to focus on getting her down to the lab, I couldn’t draw blood in her room. “I’ve got a little lab in there if you want to whip up another batch of your… secret sauce,” Priscilla said as though reading my mind.

“Uhh,” I said, stalling for some excuse.

“Come on,” she said, taking my hand. “The other girls won’t bother us.” She lead me up the stairs, her full ass swaying sexily with each step. I wasn’t big on deities, but I started praying to every god I knew to strengthen my resolve. My penis, unfortunately, was more interested in bouncing ass than in answering prayers. 

I was half mast by the time we got to her room and slipped inside. The door clicked shut behind me and I started sweating, feeling trapped. Priscilla pulled me further into a room that was every bit as expensive looking as the floor below- if a bit more tasteful. I forced myself to admire a painting of cherubs dancing around a woman on the moon in an effort to curb my arousal. 

“It’s called ‘The Celestial Madonna’.”

“Ha,” I gave an honest laugh. “I get it. I wouldn’t have guessed you were a comic fan.”

“Genetic mutation has always interested me,” Priscilla answer seriously. “The idea of ‘mutant’ human beings is fascinating.”

“No kidding?” I said, beginning to see her in a new light. “Who is your favorite?”

She wrinkled her nose and somehow even that was sexy. “That’s kid stuff. I don’t even know why I keep this around except that it kind of a clever mash-up of my other love, 17th century art.” 

I didn’t know a thing about 17th century so I stuck to the familiar. “Oh come on. I was really into comics for a while too, especially the classics. Besides, it’s not like I’m going to tell anyone,” I said.

She looked demure, “Promise you won’t tell anyone?”

I smiled, happy to finally have the upper hand in a conversation. “Cross my heart,” I said. 

“My favorite was from the other big comic universe, umm…”

“DC?” I offered.

“Yeah, thats the one. Her name was Giganta.”

“Oh,” I said, “I don’t know that one.” I didn’t like the sound of her name though. 


“Really?” Priscilla said, “She wasn’t a mutant per-se, but her power always fascinated me.”

“No kidding? Its crazy all the stuff those artists came up with huh?” I said, wondering if I should have tried my luck with 17th century art.

“Do you know Giganta’s power was, Dylan?” Priscilla said, closing the distance between us. I took a step back and my heel hit the wall. I shook my head, glancing back at the door. I had a bad feeling about where this conversation was going. Priscilla stopped, her breasts inches from my chest, and said, “She could grow.” The humming noise I’d noticed earlier was louder now.

“Wow, crazy... heh.” I said nervously, “Who would have guessed?”

Priscilla’s proximity seemed to make the temperature rise ten degrees.“Just like you made me grow last night.” A bead of sweat fell from the tip of my nose and landed in Priscilla’s exposed cleavage. We both looked down at her chest as it rolled between her boobs. My erection started sprouting immediately and I turned away. 

“Are you hot?” Priscilla said sweetly. “Would you like some water?”

“Y-yes,” I croaked. 

She stepped back and I heaved a sigh of relief. “I’ll be right back,” she said and walked into the bathroom. I found the nearest chair and slumped into it. I had to get out of here as quickly as possible. The sound of water splashing into a glass came from the bathroom and I knew I had to think fast. Take control of the situation, Dylan, be assertive. I stood back up just as Priscilla entered the room with a glass of water. 

“I need to run some tests with your blood,” I blurted out.

Surprise lit her face and she paused halfway across the room. “For the serum?”

“Yes, I need to make sure your system is synthesizing the formula correctly.”

“I feel fine,” Priscilla said with a shrug and stepped forward to hand me the water.

I accepted the glass and took a long drink, buying myself time to think. “Still,” I began. “That formula was based on a model built for plant DNA, it isn’t optimal for human consumption. The work I did last night was guesswork mostly, it wasn’t supposed to be… consumed.” 

“Worked pretty well for guesswork.” Priscilla said running her hands over her voluptuous curves.

“With who knows what side effects? You’re not going to be very happy if you start sprouting leaves will you?” That was about as likely as her growing a second head, but I was overdue for white lie number two.

“Hmm,” Priscilla’s delicate red lips pursed thoughtfully. “It does make sense to perfect the GTS, unintended side effects could… complicate matters.”

“Exactly,” I said. “And the sooner the better, where is the equipment you mentioned?” I looked around but other than the bed and the furniture I couldn’t see anything resembling a lab.

Priscilla walked past me and picked up a remote. A moment later a whirring sound emanated from the wall as a chair recessed into and a lab rotated into view. Priscilla noticed my incredulous stare and said, “Isn’t it neat? They’re very convenient.” It was like a secret lab, I thought. How much money did these people have?

“Great, just come over and sit down please,” I said, not wanting to lose momentum.

Priscilla complied, seating herself next to the lab table with an arm stretched out. “I’m ready for my treatment, doctor.” she said coquettishly. I attempted to maintain a physician’s demeanor as I brandished a syringe. “Be gentle,” she cooed.

Leaning in I noticed that buzzing hum again. What the hell was that sound? “Don’t worry. With a nano-needle you wont feel a thing but...” I said while beginning to draw blood. “You already knew that.”

“Your bedside manner would benefit from a bit more intimacy,” Priscilla suggested as I withdrew the now-full syringe from her arm. 

“I’ll uhh, keep that in mind.” I said taking a step back. The plasma cylinder slid easily out of the syringe and into my pocket.

“You’re not going to stick a girl and run are you?” Priscilla asked, standing. She was between me in the exit, I noticed with dismay. “Come on Dylan, last night was fun right? I’ve been so bored being here all day by myself.”

So that’s why no one knew she had grown, Priscilla hadn’t left the building. She took a step toward me and slipped. Her body came tumbling forward and I caught her before losing balance myself. We toppled backwards onto her bed, her voluptuous weight body pinning me down. Her heavy breasts squashed against my stomach and I tensed. Was her body vibrating? To my surprise, she rolled off of me almost immediately and laid face down on her bed.

Stunned, I managed to sit up. Lying next to me Priscilla’s body was shaking slightly. “Priscilla? Are you okay?” I said.

“You think I’m a slut,” she sobbed.

“What? No! Of course not.” White lie three was almost easy.

“Yes you do,” Priscilla said and rolled over. Her mascara was smudged by tears. “I made you get me off within ten minutes of coming in the door last time.”

“You didn’t exactly force me.”

Priscilla propped herself up on an elbow, pushing her breasts together in a breathtaking display of cleavage. The erotic visage was slightly marred by the tears still running down her face. “Come on, Dylan. I’m not stupid. I know how I must seem to you.” 

“You are a bit forward I guess,” I conceded, bringing the lie tally to four.

“I humped your leg last night.”

“Okay a lot forward,” I said, not sure where she was going with this.

“I didn’t ask to be like this you know?” Priscilla said, fresh tears forming in her eyes. “Its a condition, a genetic defect. A ‘nympho’.”

“You seem to manage it well.” I deployed white lie five with conviction.

“Really?” Priscilla said and sat up to reach reach under her dress. I turned away as her hand fished around between her legs. A moment later a buzzing sound filled the air and I turned back to see a small black device pressed between her fingers. “Does this look like I’m ‘managing it well’ to you?” The vibrator flung miniature droplets of her juices everywhere until she snapped it off. Priscilla stared at it for a few moments before her shoulders began shaking again. A tear splashed against her palm and my heart went out to her. 

I moved to her side and wrapped my arms around her. It’s okay,” I said. Her head pressed against my shoulder and shook vigorously. “I mean it Priscilla, you’re not a slut,” I said surprising myself with sincerity. The girl clearly had a wildly overactive libido and it wasn’t like I had put up any protest. If anything I was the one who should be ashamed for taking advantage of her. “It’s not like we slept together,” I said, for both our sakes. 

Priscilla sniffled and looked up. “You really don’t think I’m a slut?”

“Well, I guess that depends on how many other boys you’ve had on your bed today,” I quipped, trying to lighten the mood.

Priscilla half-laughed-half-sobbed in response and looked at the ceiling. A slight smile brightened her face as she wiped her eyes, further smearing her make-up. “Just you,” she said. 

“Well, there you go. As your doctor it’s my responsibility to release you with a clean bill of health.”

Priscilla looked at the black smudges on her hands and said, “God I’m such a mess. Still... thank you, Dylan.” 

“Anytime, but...” I hesitated, not sure if it was a good idea to press my luck.

“Yes?” Priscilla said with uncharacteristic vulnerability.

“This whole growing thing. It’s dangerous. And we could get in a lot of trouble.”

“Don’t worry about that,” Priscilla said softly, “Mom won’t let anything jeopardize my future... or my friend’s futures.”

“So we’re friends?”

Priscilla slapped my arm playfully, “Duh.” 

There was something incredibly out of character and endearing in the way she said ‘duh’ that I couldn’t help but smile. “We can put this whole GTS thing behind us then?” I asked, brimming with hope.

“Dylan. I already told you we’re not going to get in trouble so what are you worried about?” Priscilla demanded.

“Disease, mutation, I dunno- ethics!” I exclaimed, losing my cool.

“Being a mutant sounds sort of cool though,” Priscilla said, smiling.

“This isn’t a comic book Priscilla! You could get seriously ill- even die!” 

Priscilla took my hands in hers, infusing it with the warmth of her delicate touch. “Or you could make me perfect.”

Her words hit too close to home. “What if I fail? If something happens to you your family will bury me alive. And I… I couldn’t live with myself,” I said, my voice breaking at the end.

Priscilla fell silent. 

After a long period of contemplation she finally said,“Okay. We’ll let the tests decide. If you see anything dangerous happening in my DNA we’ll call the whole thing off and I’ll tell my mom everything that happened.”

“Its my call then?”

“Your discretion,” Priscilla agreed.

This was better than anything I could have hoped for. “Deal,” I said, relieved. I reached out my hand to shake on it when Priscilla suddenly embraced me. 

“Thank you,” she whispered. 

“That’s… don’t mention it,” I said awkwardly. She continued to hold me until I became acutely aware of her ample breasts squashed up against my ribs and the steady rise and fall of her chest. My own breathing quickened and I started to pull away.

“Don’t go,” Priscilla implored, meeting my eyes. “At least let me treat you to dinner.”

Feeling like I had a much better handle on the situation I nodded. “Okay, I am pretty hungry.”

“Good!” Priscilla exclaimed. She released me and stood up. “You’ll have to excuse me while I…” she glanced sheepishly at the vibrator still in her hand. “Freshen up.”

“Oh!” I said and made the mistake of standing straight up. My erection was obvious.

“Ooo, looks like I’m not the only one all hot and bothered,” Priscilla said gleefully.

“Gimme a break,” I said shifting my pants uncomfortably. “It’s not like I’m used to sitting with a girl in her bed especially not-” I stopped myself from saying something embaressing.

“Especially not what?” Priscilla asked expectantly. 

I muttered a response.

“Come on, we’re friends remember? Just tell me.”

“Sexy okay? You’re sexy.”

“Aww, that’s really sweet Dylan.” Priscilla said, “You know maybe we could…” She looked away, blushing. “You know… help each other out.”

I could scarcely believe this shyness coming from the aggressive girl I’d met the night before. It made me feel a bit more confident and I said, “Like last night?”

“Well,” Priscilla looked sheepish, “Maybe not exactly like last night.” Her tone changed. “Ugh, I hate this, I’ve been running this stupid thing all day-” she shook the vibrator “-and I just can’t. I need…” 

“Its okay,” I smiled, enjoying the role reversal. “We’re friends, you can tell me.”

“Please don’t make me say it.” Priscilla said pleadingly.

My penis was as hard as ever but for once I wasn’t fighting it. It felt good to be in control a bit. “Your wish is my command, your highness.” I said, giving a slight bow.

Clearly not amused, Priscilla spoke through gritted teeth. “Oh is it now?”

“Well,” I said, my confidence crumbling. “I-”

“Oh don’t back out now.” Priscilla said advancing on me, “You like seeing me squirm?”

The bed bumped the back of my legs. “A little, maybe,” I admitted.

“Then that’s what you’re going to get.” She pushed me back down to the bed with surprising force. Had she been this strong last night? A wicked smile was painted on her face as she bent over the bed and I watched her panties slip down to the floor. Her hand reached over my crotch and I tensed but it passed over me to the opposite side of the bed. She pulled herself onto the bed and straddled me. The familiar sweetness of her sex assaulted my nose as the damp heat of her crotch pressed against my stomach.

“Ready for your appetizer?” Priscilla said without any trace of her previous shyness. My breath caught as she began sliding up my chest. Her breasts jiggled and bounced as she moved up my body. Her naked sex suddenly filled my vision in the half-darkness under her dress. “Bon Appétit,” she declared, and sat on my face.

The glistening wet lips of her sex greeted me with a sloppy kiss. She was shaven except for a light fuzz that tickled my nose. The overpowering sweetness of her musk threatened to drown me. Tingling with excitement and wielding only the most cursory knowledge of cunnilingus I tentatively stretched out my tongue. The moment it made contact with her nether region two things happened. First, I tasted an incredibly sweet, musky flavor. Second, Priscilla moaned heavily and gushed girl-cum all over my face.

Her body twitched spasmodically for a few moments before she said breathlessly, “You have no idea how badly I needed that.”

Recovering from my shock of having elicited an orgasm on contact I mumbled, “Glad I could help.” from under her dress. 

“Oh you’re not done,” she giggled. “That just took the edge off.”

I opened my mouth to reply and her pussy dropped back onto my face, pre-empting any response. Despite feeling self-conscious over the rough treatment I was harder than I’d ever been in my life. The voluptuous orbs of her ass bounced against my chin as she shifted above me and I thrust my tongue to back inside her now soaking wet slit. Priscilla moaned again and returned with a thrust of her own, then another. She began to grind against my face, clutching my tongue in the powerful muscles of her vagina. 

In one smooth motion that never released my tongue from its fleshy prison, Priscilla swung her body around. Now facing away from me, her hand grabbed my dick through my pants. I let out a muffled yelp into her muff. She continued gyrating with abandon, moaning steadily. “Stick out your tongue!” she demanded. I was doing so without her telling me and didn’t understand until she raised off my face for a moment- then impaled herself down on my outstretched tongue. Her juices squelched against my face as she lifted up and repeated the motion. Each thrust bounced and jiggled her pert round ass lewdly.

Holy shit, I thought, she is fucking my face. Lights danced in my vision as I came harder than I ever had in my life. Priscilla massaged my penis while I thrust into the air and a sticky wet spot spread in my pants. No sooner had I sunk back into the mattress than she continued riding me as though nothing had happened. Juices flowed heavily, soaking my face as she plunged downward faster and faster. My tongue began to get sore and her syrupy secretions were making it difficult to breath through my nose. I withdrew my tongue to speak and Priscilla’s hand instantly lashed out to smack my chest. “Keep it out!” she shouted.

Stunned, I obeyed. Forced to swallow to avoid choking the world narrowed to an alternating series of wet darkness and gyrating flesh. Priscilla’s moaning condensed into a single escalating note as she pummeled my face face with her pelvis. My increasingly sore tongue was repeatedly sheathed in the furnace heat of her sex and slathered with sweetness. I began to suck gulping breaths between each thrust, desperate for air. Her hands braced on my thighs and I was shocked to find I was hard again.

“YES!” Priscilla cried, “Oh god, YES!” Her thighs crushed around my head and cum spurted into my mouth as though from a hose. It hit the back of my throat and I gagged, instinctively pushing her aside as I turned and coughed up fluid. 

I was still recovering when fingers twined in my hair and forced me to meet Priscilla’s devilishly glinting eyes. Her make-up was smeared such that she looked like some sort of crazed sex demon. “Oh don’t act like you don’t like it,” she said, squeezing my penis to emphasize her point. “You remember what I like though, right?” 

“Urgh,” was all I could manage to say. My tongue felt like it had been run through a blender.

Priscilla sighed and said, “I like a boy that swallows, Dylan. Don’t waste it.” And with that she dropped her muff back onto my face. 

I didn’t know whether to be terrified or impressed. How many times did she need to orgasm before she was satisfied? I didn’t have to wait long to find out. Priscilla’s fingers buzzed frantically over her clit and she slumped forward to brace herself on the headboard as a third orgasm came pounding down. Hot fluid splashed against my chin and then into my stunned mouth. It was an incredible quantity, filling my mouth and drooling over my lips. Her eyes watched me closely. Dutifully, I swallowed. 

Apparently watching me guzzle her cum was enough to bring Priscilla to another orgasm because she screamed in ecstasy and another jet of hot fluid erupted into my mouth. It was like trying to shotgun a beer, which I’d only ever done once. I gulped and sputtered down a cup’s worth of her juices, gasping for air. Mercifully, Priscilla rolled off and laid beside me. 

“Ahh, what a relief!” she exclaimed happily. “That was great, Dylan.” 

After regaining my breath I said, “Yeah any- I mean, you too.” I wasn’t sure if I was lying or not at this point.

Priscilla sat up next to me, flush with energy. I felt completely drained. “Aww, you’re still hard,” she said sadly. Well, I thought, not completely drained. “Let me fix that for you.” She scooted down the bed, unzipped my pants and had my dick out in an instant. The next instant my member was surrounded by the wet warmth of her mouth. Suddenly, having to swallow a bucketload of girl-jizz seemed a small price to pay for the incredible sensation of Priscilla’s tongue tracing circles around my shaft. 

I didn’t last long and to her credit, Priscilla didn’t miss a drop. 

Then she started to grow.
