My name is Lucy. I’m 5’8″ with long brown hair, pale skin. My breasts are firm C cups, topped with small pink nipples and my ass is firm; the most important detail about me though is I am the obedient slave of my mistress. While I might be considered beautiful by many, my mistress Elizabeth is what I describe as a goddess: 5’11”, jet black hair, perfectly round and firm D cup breasts and an ass to match, the sight of her is enough to make most lust for her.

Both of us are 26 and I have been my mistress’ slave for the past 3 years ever since meeting her in my final year of university.
Today started like any other day, I wake up before my mistress to prepare her breakfast and coffee, and once done return to the bedroom to wait by her side with her silk robe in one hand and my leash held in the other, “good morning mistress. Breakfast is prepared for you, what do you wish from me?” I ask her as she steps out of bed and I wrap her in the robe, “just follow me for now princess.” She pulls on the collar and I follow obediently.

Once we get to the kitchen she sits down to her breakfast “get under the table and eat me out slave” she says “of course mistress” I reply, slinking under the table and begin to slowly lick at her clit, sliding a finger into her pussy making her moan as she eats, “good princess, once you make me cum you may eat.” Her breath comes short and sharp as I attack her clit with my tongue, my fingers going deeper into her pussy and my other hand reaching up from below the table to pinch at her nipple softly “Yes! Good princess, just like that” her food forgotten, she begins to play with her nipples, screaming in pleasure as she orgasms, coating my face in her cum.

“Thank you for the meal mistress, is there anything else I can do for you?” I ask, licking up all the cum that I can. “Just come clean me in the shower, I have errands to run today.” following my mistress into the bathroom, I remove her robe and begin the shower. Once inside I begin washing her body, paying special attention to her breasts and pussy as I clean “you missed a spot slave” mistress says, turning from me and displaying her ass, “lick it clean.”
“Of course mistress” I say as I spread her cheeks and begin to lick her cute star. Her moans entice me to dig deeper with my tongue “good princess, now dry me off.” She says, “Of course mistress” I reply, turning off the water and step out to grab a towel, drying her off completely.
Returning to the bedroom she changes into black lacy lingerie and a tight fitting black dress, “your chores for the day are to clean the house and all the toys, replacing any dead batteries as well. After that you may dress and do as you please, however I want you at the door waiting for me at 5pm exact”
“Of course mistress, I will have everything completed by your return”

As Elizabeth leaves I begin my chores which take me until early afternoon to complete. Once done i dress in a short skirt and tank top, ignoring underwear or a bra. Deciding that I have a few hours to spare, I call up my best friend from my uni days, Jessica. “Hey Jess! It’s Lucy, how’ve you been?”
“I’m great! Better than great actually because I just finished my new formula, you should come over and see what I made” she replies. Jess and I both met when we started university, both of us were studying to become pharmacists with a focus on starting our own company to sell what we dreamily described as Fantasy Cures; formulas to fulfil your wildest desires. I of course met my Mistress and schooling meant nothing to me afterwards, money being no issue either because of Mistress’ substantial trust fund and connections. “What did you make this time?” I ask
“It’s easier to show you, come over to mine as soon as you can”
“I’ll leave right now”

I grab my purse quickly and jump in my car, taking the quickest route to Jess’ house. As I get to the door and knock, Jess appears quickly to pull me inside. When I knew her at university, Jess was a short, curly-haired, flat-chested quiet girl but over the years through the use of her own formulas, she’s grown her breasts to D cups, an ass you could bounce coins off and is now 5’10” with pixie-cut blue hair. “So you know how in uni we got really drunk and fucked with the strap-on?” she asks, “yeah, I remember” god do I ever, even when she had no tits, she was an amazing fuck, “Well I was drinking recently and thinking about those nights, and came up with something: what if we could do that without needing a strap-on?” I look at her quizzically “What, like making us into futas?”

“Exactly like making us into futas” she then pulls out a small vial of blue liquid, “this is what I worked on for the past 3 months, a futa serum. Drinking this will grow you a cock bigger than any man you’ve been with. If I made it right, the serum wears off after you orgasm”
“So I could drink this, grow a cock to fuck you with and be back to normal in time to meet my Mistress?” I see a flash of jealousy in her eyes, Jess never approved of me choosing Elizabeth over her, “Yes you can be, do you want to?”
“YES!” I grab the vial from her hands and down it, quickly feeling the change begin. From beneath my skirt, my clit engorges and testicles form, growing out from underneath and forming into a thick, 11” cock which immediately begins to drip with precum. At the same time, I feel a heat flow through the rest of my body ending in my chest as my breasts begin to expand and I begin to grow, ripping my tank top apart until they reach what must be at least an E cup. With my clothes destroyed beneath me, I look at a mirror nearby to see my new, 6’2” form “I look perfect” I say, touching my new appendage “You are perfect” says Jess from behind me. As I turn around to see her naked and dripping wet, I’m overcome with intense lust. Picking her up with my newfound strength, I take her against the wall, forcing my cock into her waiting cunt.
“Ahhh!” Jess begins to scream in pleasure as I force the entire length of my cock into her, “fuck me harder Lucy, fuck me!” her hands dig into my back as I fuck her. Soon, I feel pressure building in my loins “I think I’m about to cum!” I moan into her ear “wait!” she says, “I don’t know what affects your cum will have”
“well we’re about find out!” I say as I make one last thrust before emptying my new balls into her
“No Lucy! You shouldn’t have done th-” her words cut off as her eyes glaze over “you should’ve have let me eat it all up Mistress” she says as her eyes refocus, “What did you just say?” I ask, unsure what just happened, “I called you Mistress, unless you’d rather a different title?”
Placing her on floor, “What happened to you?”
Thinking for a moment, she responds “My best guess is that the formula causes your cum to have a mind-control effect. I don’t know if it will last, but for now I’m your slave mistress”
Thinking for a moment, I look down to find my cock and enlarged breasts still there “I thought you said it was temporary?”
“I might have gotten it wrong, this hasn’t be tested on people before. Have I done wrong Mistress?” she looks at me sadly, though her eyes still filled with lust, “hmm, no I think this could be interesting.” I glance over at the clock to see that it is already 4:30, “Oh shit! I need to get back or mistress will -”
“she’ll what? Punish you? You’re the big one with the cock now, what can she do to you?”
The realization that I now have control causes a rush of lust, “You’re right slave. Now suck my cock.”
“With pleasure Mistress”
