"Wake up, baby."

I felt a gentle nudging at my shoulder. I responded appropriately by burying my head into my pillow with a protesting groan.

"Rachel and Chelsea are here. Do you want to go to the beach or not?"

I sighed, knowing I had no choice but to get up. I never was a morning person, but I

did

want to get to the beach before it got too crowded.

But...why was I in bed? Didn't I fall asleep in Jenny's lap? No, wait. I was holding Mistress in my arms as I dozed off, and then...

Oh. Master must've dismissed Jenny and carried me to bed at some point last night. It was strange having both sets of memories in my head, but they were easy enough to sort through.

Being Jenny was wonderful. I had felt so fulfilled, without a care in the world. My mind had been so restrained that it couldn't contain anything other than my love for Master and the intense pleasure of my big, voluptuous body.

Reveling in those memories, I groped at my huge, massive --

"Why are my boobs so small?" I asked, whining into my pillow.

"Jen, they're still bigger than your head."

I paused, realizing that I was back in my "normal" body. My boobs were still huge by anyone else's standards, but last night seemed to have completely upended my sense of scale.

I turned over to face him, my too-small breasts swinging from side to side. "Can you make them a bit bigger, Master?" I asked, biting my lip as cutely as I could. "Please?"

He kneeled beside me, running his hand through my hair.

"I know what you're doing and I still can't help but fall for it." He smiled, petting me as he twirled one of my nipples. "But what about Rachel and Chelsea? Do you want them to notice?"

"Actually...I was thinking about telling them about the collar today." I looked him in the eyes with genuine apprehension. "If that's okay."

"If you trust them, I trust them," he said.

I reached over and pulled his head to mine, locking my lips with his. As we kissed, I felt that wonderful warmth fill my chest. With my other hand I groped at my boob, feeling it enlarge between my fingers.

Our faces parted, a string of saliva trailing between our lips.

"Is that better?" he asked.

I pulled myself up into a sitting position, and found that my breasts were large enough to rest their full weight in -- and around -- my lap. Standing up, they hung down to my waist, my arms

just

long enough to comfortably reach my nipples. They were so,

so

heavy, yet they brought me no pain or discomfort.

"For now. The fact that I can still walk is a bit disappointing, though," I replied, only half joking.

"We've got all day." He winked and handed me some clothes: a pair of red booty shorts and a light blue t-shirt that was tailored specifically to my...unique figure.

After a brief struggle to get them on -- both pieces of clothing were skin tight, and my swinging breasts wreaked havoc on my balance as I shifted my weight from one foot to the other to slip on the shorts -- I looked myself over in the mirror.

The shorts formed perfectly around the contours of my bubble butt, wedging slightly between my cheeks, and they were so tight in the crotch area that I was sporting some very prominent camel-toe. The shirt was just long enough to hide my nipples, leaving a very generous amount of under-boob on display. The fabric hung loosely over the curve of my breasts, and I was certain that any small breeze would be enough to expose the red of my areolas. The two large tents that had formed over my nipples grew even further as I realized how perfectly my new outfit showed off my body.

"God, you're sexy," Master said before spanking my ass.

"

Mmm

. Right back at you." Master's shirt was tight enough to highlight his lean, muscular physique, and I could see the bulge of his cock even through the bagginess of his swim trunks.

My hand began inching toward his crotch, but Master interrupted me with a cough.

"We, uh, should probably talk to Rachel and Chelsea before we get too excited," he said, obviously as caught up in the moment as I was if the rising tent in his shorts was anything to go by.

I blushed. "Haha, yeah, probably." We were just getting hornier by the day, weren't we?

We entered the living room to find my friends sitting together on the couch, having a quiet conversation. They were both wearing denim short shorts and sandals. Chelsea had on a tight, zipped-up hoodie, while Rachel wore a white t-shirt that was just transparent enough for me to see the outline of her red bikini top. My brows furrowed. There was something different about them, but I couldn't quite put my finger on it.

They both looked up as we entered the room, their eyes widening as they saw my expanded breasts.

"Whoa, you too?" Rachel asked.

"Huh?" I replied eloquently.

"Our, um." Chelsea blushed as her eyes briefly flitted toward Master. "Our chests grew, too," she muttered, crossing her arms over her own rather large assets. Too large.

I stared at them in shock. Now that I knew what I was looking for, there was no mistaking it: their breasts were definitely bigger. If I had to guess, they had both gone up a couple cup sizes. Rachel's pert C cups had grown to double Ds, while Chelsea's D cups -- which I had been jealous of for so long -- had bumped up to F cups, at least.

"My milk...worked on you?" I turned to Master, and he seemed just as surprised as I was.

"Worked on us?" Chelsea asked. "You knew it would do this?"

"In that case, you owe us some money," Rachel said. "We had to get new bikinis yesterday."

Chelsea frowned thoughtfully. "And I

am

probably going to need to replace most of my tops. Not to mention all of my bras."

We really messed up. To any normal person, growing two cup sizes in a day would

obviously

be terribly life-changing and inconvenient. I could only imagine the embarrassing questions friends and family would ask, once they noticed.

"I'm so sorry!" I said, panicking. "We thought Master's powers wouldn't affect anyone else, but we can fix it!"

I rushed into the kitchen and got a couple cups, ready to squeeze some breast-reducing milk into them. I returned to the living room to find the others staring at me. Master had a hand to his face, clearly embarrassed, and Chelsea's head was swiveling between us so fast I was worried it would come off. Rachel was eyeing my collar with a widening smirk.

"M-master?" Chelsea asked.

Shit.

"I was wondering what was going on with that collar," Rachel said. "Having trouble keeping your bedroom games in the bedroom?" She wiggled her eyebrows while Chelsea just stared at me.

This was

not

how I wanted to start this conversation. I could feel my eyes beginning to sting.

"W-we can talk about that later. First I need to fix this." I looked to Master, and he nodded. I turned to go back to the kitchen for some privacy, but before I could get there Chelsea got up and hugged me from behind.

"It's okay, Jen," she said. "We're not mad."

"You're--" I interrupted myself with a sniffle. "You're not?"

"Honestly, I was going to ask you for more." Rachel joined our hug, intentionally leaning into the side of my breast. "Sorry about the bikini thing. I was just messing with ya."

"I love you, girls," I said, wiping my eyes.

"We love you, too, Jen," Chelsea replied.

"Yeah!" Rachel said. She grinned. "Now, about '

Master's powers

'."

I sighed, knowing for a fact that she was never going to let me live this down.

* * *

"Damn, Jen. You were scrawny," Rachel tactfully remarked.

I crossed my arms over my washboard of a chest and slouched into the couch. "Yeah, well, hopefully this is the last time I'll have to endure being a beanpole."

During my explanation, the girls wanted to see some proof of the collar's powers, and Chelsea was curious about what I had looked like before Master and I owned it. With my permission, Master reverted me to the body I was born with, and

holy shit

was it embarrassing. Before the collar, I wouldn't have said I was

this

unsatisfied with my former body, but after spending over a week as a sex goddess, going back was

thoroughly

uncomfortable. It didn't help that my clothes were so big on me that I might as well have been wearing bed sheets.

"In retrospect, it does explain why guys weren't drooling all over you during high school," Chelsea said. "In fact, I don't remember ever taking much notice of how big you were, even though you were, like, a J cup by sophomore year."

"So it changed your memories of her appearance, but not the actual events in your life involving her. That's interesting," Master said.

He had been fairly quiet up to that point, letting me do all the talking. His statement seemed to remind Chelsea that he was there, and she cast a worried glance at us.

"Um. Can we talk to Jen in private? Without," she pointed at my neck, "that?"

Master sagged, and I could tell that he had been dreading this moment.

"Sure. I understand." He pulled me toward him and unlocked my collar.

Once again I felt that wonderful warmth as my body was returned to its true form. I felt my shorts tighten around me as my swelling ass and thighs fully filled them out. I was annoyed to realize that my breasts were still too small to similarly fill out my top, since the change from earlier wasn't made permanent. I'd have to remind Master to re-enlarge them once I got my collar back on, but until then my T-shirt would just have to drape loosely over my boobs.

Master handed me my collar and stood up to leave, a look of apprehension clear on his face.

"Don't worry, Master. They'll understand," I reassured him.

Rachel snorted, whereas Chelsea narrowed her eyes in suspicion.

"Why is she still calling you that?" she asked Mast...er. Wait, why

was

I still calling him that?

Master gave a nervous laugh. "I, uh, removed that compulsion a couple days ago. I wanted to see how long it would take her to notice."

Rachel giggled at my expense, and even Chelsea couldn't stop a small smile from breaking into her otherwise serious expression.

It really shouldn't have been so surprising. Calling him Master felt so natural to me at this point that I wasn't even thinking about it. Though I had to admit that it probably wasn't healthy to think of him that way

all

the time.

"Well, uh, I'll be in the bedroom," Mast-...Travis said, leaving me with my friends.

"Are you sure about this, Jen?" Chelsea asked as Rachel calmed her snickering. "If everything you said is true, that thing is literally turning you into his...his sex slave."

"Yes, I'm sure," I replied. "It...excites me. I don't know how I can explain it to you, but when I'm in that position, it makes me feel

so good

...and not just physically." My shoulders slumped. "You must think I'm some kind of freak."

Rachel gently grasped my shoulder. "You're not the first sub on the planet, Jen."

"I don't think you're a freak!" Chelsea said defensively. "It's not about that. And I, um, certainly can't hold it against Travis for enjoying it as well."

Rachel and I raised an eyebrow at that, but Chelsea didn't seem to notice.

"It's about the fact that you're giving up

all

of your control. What if you wanted to take it off and he just said no?"

"He wouldn't do that. I trust Ma-...

Travis

completely. He loves me and I love him, end of story."

Chelsea looked like she wanted to say more, but eventually relented. "Well...if you say so," she said, sighing.

"And if he ever steps out of bounds, you'll always have us to set him straight," Rachel said, slamming her fist into her palm for emphasis.

I smiled. They really were my best friends for a reason.

"Now," Rachel started, eyeing up my breasts while groping her own, "about that milk..."

* * *

"I think my milk can affect others because it's still a change that you're making to

me

. It's part of my body, and you're just changing it's properties," I said.

"I see what you're saying, but can it do

anything

? That really seems to fly in the face of the collar's rules," Travis replied.

He had reentered the room and was relieved to find that Chelsea and Rachel didn't object to our use of the collar. I had put it back on and let him regrow my breasts. My shirt was once again taught against my boobs, and poor Rachel was having a rough time focusing on anything else. Honestly, I found the attention somewhat arousing, and the fact that I could feel my nipples stiffening against the fabric of my shirt probably didn't help matters.

Going back to the matter at hand, I contemplated Travis's argument. It was true that this development seemed counter to the intention of the collar's rules. Was it just an unintended loophole, or were there more restrictions to it than we thought?

I nodded to myself. Only one way to find out.

"Let's experiment!" I said.

Chelsea sighed. "And I suppose we're going to be the guinea pigs."

"If that's alright?"

"Sure!" Rachel said, matching my enthusiasm. Chelsea shrugged.

"C'mon, Travis. We need to plan our methodology." I made my way to the kitchen, while Travis simply smiled and followed behind me.

* * *

"We're ready!" I called to the girls.

They entered the kitchen and were greeted by two rows of plastic cups on the table. Each cup was marked with a number, and contained a sample of my breast milk. If our assumptions were correct, each sample of milk would cause a predetermined change when drunk.

Rachel whistled. "Really digging the headlights, Jen."

I groped my breasts just below my nipples, emphasizing the two damp splotches on the front my shirt. "I'm glad you like them," I replied with a wink.

After I had milked myself for the experiments, I had simply pulled my shirt back over my breasts, intentionally letting the errant traces of milk on my nipples stain into the fabric of my top. When Travis pointed them out, I had asked him to make my breasts continually leak just enough to keep my nipples wet indefinitely. My milk was one of the things that made my body special, and I wanted everyone to be aware of it.

Speaking of, my teasing left Rachel speechless. Even Chelsea was blushing, and I noticed with satisfaction that she couldn't manage to tear her eyes away from my little show.

"W-what do you need us to do?" Chelsea asked when she finally managed to focus on something else, namely the cups on the table.

"You're both going to drink each cup in sequence, and we'll observe what happens. Simple."

"We don't get to drink from the tap?" Rachel asked. I think she had meant it to sound playful, but I couldn't help but hear a tinge of disappointment.

Chelsea's blush deepened, and I was reminded of our brief tryst in the bathroom yesterday.

"Do you...want to?" I asked.

"Yes!" Rachel said immediately.

We all looked at Chelsea, and at that point she had gotten so red that I was beginning to worry about her health. She looked up at me, and then darted her eyes toward Travis.

Rachel followed her gaze and smirked. "Is that alright, 'Master'?"

Travis mirrored her expression. "As long as I get to watch," he replied.

"This guy's got his priorities straight!" she said. "Chelsea?"

We returned our attention to the blushing brunette, and after a few long seconds she nodded.

"You remember the sample order?" I asked Travis.

"Yep."

With building excitement, I pulled up my shirt, fully exposing my huge, leaking tits. I walked to the living room -- my breasts bouncing with each step -- and sat myself in the middle of the couch. I gestured at my friends to sit beside me, and they silently complied, their eyes glued to my chest.

"Experiment number one!" I hefted my breasts to my sides, offering each of them to my friends. Rachel roughly grabbed my left tit and quickly latched on to my nipple, while Chelsea gazed reverently at the other, licking her lips before latching on as well.

I felt twin pulls on my teats, followed shortly by the release of milk. I gently hummed in pleasure. Both of them were being even bolder than yesterday. Rachel was vigorously twirling my nipple with her tongue, and I could feel Chelsea making tentative licks as well.

I was caught in a trance, once again enraptured by the two beauties suckling on my teats. After a few minutes, though, I was brought out of it by a polite cough.

"Sorry to interrupt," Travis said, "but I'm not sure how big they wanted to get."

I blinked in surprise. That's right, the first experiment was just to confirm what happened yesterday. They were only supposed to drink half a cup, which should've been just enough to confirm that their breasts had grown.

Oh. Wow.

I put my hands under their chins and gently pulled them away from my nipples. For a moment they still looked dazed, but as they came around they shifted uncomfortably. Chelsea was the first to notice.

Her breathing quickened, a look of astonishment on her face. Ignoring everyone else in the room, she unzipped her

very

tight hoodie, revealing two huge breasts that had slipped out of her now inadequate bikini top. They were just as big as my "normal" size, each boob dwarfing the size of her head. She lightly ran her hands over them, brushing her engorged nipples with the tips of her fingers, before softly groping herself. She made an adorable little squeaking noise when she pinched at her pink nubs. I made to get her attention, realizing she probably wasn't going to stop without intervention, but before I could, I was interrupted by a loud, astonished gasp coming from my other side.

"Oh my god! My tits are huge!" Rachel shouted while grabbing said tits through her shirt. They were about the same size as Chelsea's, maybe a bit smaller but no less impressive.

Where Chelsea's absentminded breast-play was slow and sensual, Rachel's was rough and frantic. She was absolutely

mauling

them, her hands squeezing so hard that they almost seemed buried into her pillows of flesh. She made a show of lifting them up in front of her face and dropping them, letting them sway and jiggle for only a moment before returning to her enthusiastic groping.

"This is awesome!" she said, her voice trailing into a loud, seductive moan.

"You didn't happen to add an aphrodisiac effect, did you?" I asked Travis.

He shook his head in amusement. "Nope. Looks like we're not the only one's here with overactive libidos."

I turned back to Chelsea. It seemed that Rachel's display had brought her out of her trance, as she now had her hoodie zipped up and was pointedly looking away from us, red as a tomato. Though I did catch the occasional furtive glances toward Travis's crotch. He wasn't even

trying

to hide the massive tent that had formed in his trunks.

"Okay!" I loudly declared before clapping my hands together.

All eyes turned to me, though Rachel was still absently fondling her tits.

"Maybe we should go back to the cups for the rest of the tests," I suggested.

"Probably," Travis said.

"Y-yes," Chelsea agreed, though I suspected it was only for propriety's sake, going by how she licked her lips while peeking at my still exposed breasts.

Rachel pouted.

* * *

Things progressed relatively quickly without the distraction of direct breastfeeding. We established that my milk could do practically anything. Body changes, mind control, mind alteration -- even our control of external perception could be replicated. We could even tie the changes to a trigger -- such as "Chelsea will raise her hand whenever she hears someone clap" -- as long as the trigger wasn't initiated by the person it affected. As far as we could tell, the only thing it

couldn't

do was bestow the drinker with their own magical powers.
