MILF, Part II

Anne stood in the doorway, her chest heaving with rage. She had every right to be angry – she had caught me with my dick literally inside her mom, whose humongous tits had finally stopped growing, and were settling on comfortably on being the biggest boobs I had ever seen.

Anne was my girlfriend, and she’d always had big breasts – around a large E; they’d always been a great part of our sex life. But as she entered the room now, they were a lot bigger.

They looked more like G or GG-cups, big, fat, round, pert things that stuffed her top to the max. I loved that she was still wearing the same strappy vest that she’d had when she got her breasts altered – now it looked pitifully small, her massive tits bulging out over the top of the cups. Her bra was a joke, creating so much overboob.

“How could you do this, mum?!” She yelled, her massive tits wobbling and shaking.

And I wasn’t sure if she realised, but her tits were growing. Her top, already designed for boobs of a much smaller scale than Anne’s, was really straining now as her breasts expanded out of it, bulging over the top and spreading larger and wider on either side. I’d pretty much just had sex, but I was already getting hard again.

“It’s not what it looks like, Annie.” Janet said, her enormous breasts settling at the rough size of medicine balls – or were they even bigger? – my mind was reeling all over the place.

“Not what it looks like – mom, my boyfriend is literally in you!” Anne bellowed, jumping a little with anger, which caused her huge breasts to shake and wobble. And grow a little bigger again. Had she really not noticed they were growing?

I suddenly had a thought – if Janet could control her boobs with thought, maybe Anne could too – and maybe her anger was doing the same thing. I figured it was probably time to make the best of a very, very bad (and don’t get me wrong – very, very good) situation.

“Look Anne, this is totally my fault – I came over to see you, but you weren’t here, then I got talking to Janet, and she’s got these crazy hot new boobs-”

“Could you at least disengage!?” Anne shouted.

It was a fair point. I eased my cock out of Anne’s mom, who sat on the bed and covered herself with a sheet. Anne’s breasts swelled a little larger. Her boobs were digging like mad into her top. They were getting really big now. I was getting turned on all over again.

“As I was saying, your mum has these crazy-hot boobs, and once I saw them, I kind of couldn’t resist. I know it’s no excuse-”

“Yeah, no shit!” Yelled Anne, her breasts shaking, wobbling and growing all the time. My plan was working. I might just get out of this yet.

“But – as you know – we did it, and I don’t regret a thing.”

There was a gasp.

I braced myself.

“Pete!” Said Janet.

Anne turned red in the face, her breasts swelling larger. “Are you fucking kidding me?!”

“Sorry, but huge-boobed sex is the greatest thing in the world, and Janet offered me something you never could. Your boobs just aren’t big enough for me, Anne.”

This was fast becoming untrue, but it was also having the effect I wanted – Anne’s breasts were getting really large now. As her angry chest heaved up and down, her boobs expanded outwards and to either side, blowing up like huge balloons. Her spaghetti strap top was starting to buckle under their strain.

“I got these for you, Pete. And you cheat on me with my mum?!”

I didn’t really have a response to that, but I did my best. “And look how big they are now.”

Anne looked down and for the first time realised how big her tits had grown in the last few minutes.

“Oh my fucking god! They’re huge!” She cried, feeling her massive tits with both hands. “It looks like a butt!”

It really did – a massive, gorgeous line of cleavage ran down the middle of Anne’s phenomenal breasts, which curved out like two huge cheeks, resting on her slender frame.

“The doctor didn’t say I’d get this big.” She murmured, poking one of her massive balloons with a finger. It made only a little impact. “So full.”

“Exactly. The only way to make them really huge was to make you angry beyond all belief. That’s how you unlock their true size.”

Anne looked at me. She wasn’t stupid.

“Really, Pete. Really.”

“It’s true!” I continued. “Look how big they’re getting now!”

Her breasts were growing again, taking up more and more space. Her top was going to shatter soon, her enormous breasts were practically pouring out of it.

“So what do you say? We have the greatest, huge-boobed sex of our lives, get these babies as big as they can get, and never speak of this again?”

I paused, waiting for a response. This was the craziest gamble I’d ever made.

Anne looked at me. She looked at Janet. Janet looked at me.

I looked at Anne.

And one of Anne’s spaghetti straps popped off, as her huge tits slowly started to burst out of her top. The rest of her boobs soon followed – they were enormous now, huge J-cup monsters that swelled and bulged with every breath she took.

“Um, is that a yes? I genuinely don’t know if you’re agreeing or just consumed with rage.”

Anne started pulling off her jeans, but her huge boobs got completely in the way. She rolled to the floor, her massive shuddering jugs wobbling hugely in the air.

“I was going to say something clever about it being both, but then I fell over.” She said from the floor, in a tone of both deep rage and unwilling amusement. “Take my pants off and make me come like never before, and I’ll think about not killing you in your sleep.”

I leapt off the bed and started pulling off her jeans. Anne’s massive tits wobbled high and free in the air, the remnants of her top falling to the side. They were so huge, that once I was by Anne’s crotch, pulling her jeans off her slim figure, when I looked up, tits was all I could see. They were like two huge zeppelins, sailing into the sky. I grew fully, legitimately hard this time. So quickly after sex! In fairness, I really loved big boobs.

“What about me?” Asked Janet, looking a little sheepish under her blanket.

“You can watch.” Ordered Anne. “Seeing your daughter get the fucking of her life will be the first step towards your punishment.”

“Creepy.” Said Janet, but nothing more. She closed her eyes and started to focus.

I removed Anne’s jeans and her underwear and leapt onto her, kissing her and stroking her massive boobs.

“On the bed”, she grunted, clearly having difficulty dealing with being on her back with such humongous breasts resting there.

I got up and jumped onto the bed, where Janet was still sitting there, her eyes now closed. What was she doing?

I heard a cough from the floor.

“Little help?” Anne asked, lying there like a turtle on its back, her phenomenally large boobs weighing her down to the floor.

“Looks like I’m going to have to start working out if these get much bigger.” She noted, as my erection grew harder. She was so huge. Was she even going to be able to function in society with boobs this big? Did they go down in size? How big were they going to get?

This last question dominated my thoughts as soon as it entered them – Anne’s breasts were as big as her mum’s had been at their biggest, and showed no signs of stopping.

I grabbed Anne’s wrists and pulled her to her feet. She leant into me and placed her palms on my chest, the rest of the space being taken up by her gargantuan balloons, which were approaching the size of small beachballs. I kissed the tops of both of them, and started sucking on her nipples.

“The bed…” Anne groaned, getting more and more turned on as her boobs slowly groaned bigger.

The creak as Anne lowered her huge form onto the bed was deeply arousing, belying just how heavy she’d become with this tremendous growth of hers. She lay on her back, letting the softness of the bed compensate for the massive weight on her chest, which was now wider than she was, and still growing.

“Now, fuck me while she watches.” Anne ordered, smiling as I placed my big cock between her legs.

“You sure?” Came a voice from my right. Janet pulled down the blanket, revealing a stupendously large pair of boobs. “I’ve not been slacking, you know. And these babies get much bigger.” She hefted a large, beachball-sized breast, rubbing a rock-hard nipple. “Interested?”

“Mom, fuck off!” Anne shouted, anger flaring up in her.

This was perfect.

As I started to fuck Anne, her breast growth increased with her rage, and her boobs expanded even more. They were titanic now, almost twice as big as her head, and they wobbled and shook like made as her body was rocked by the fucking I was giving her. Her tits threatened to smack her in the face, they shook so much, I was finding the whole thing beyond arousing.

All the while, Janet was watching us, playing with herself and growing bigger and bigger, trying to compete with her daughter. I was so confused by how turned on this was all making me, so I decided not to think about it too much. Every time I looked over to Janet, Anne reached an arm up and slapped me in the face, drawing my attention back to her. But it made her boobs grow a little bigger, so it was all worth it.

As Anne’s tits swelled to the size of beachballs, I knew I was going to come. It was too much. They were too big. I mean, not actually too big, (was that possible?) but too big for me to handle right now. And the look on her face as we both came closer to orgasm, combined with how huge she’d becoming in such a short space of time…it was driving me wild.

And so, as her breasts reached comfortable beachball size and a little beyond, I felt my dick hardening, preparing to cum, and I shot a massive load of jizz straight into Anne’s cunt.

All the while, I heard Anne coming, Janet moaning, and both of them still slowly growing while we all shared a massive group orgasm – and for me and Janet, that was the second one in a very short space of time.

And as soon as it had begun, it was all over.

I felt raw, exhausted and drained. And deliriously happy.

Anne lay there on the bed, looking up at me from beneath her tremendous, beachball-sized breasts, resting her hand on my arm.

“I’m still going to kill you in your sleep”, she smiled, “But that was phenomenal sex.”

“Well, guess I’ll leave you two to it”, said Janet, awkwardly getting up off the bed. I’d assumed the awkwardness was due to her embarrassment, but it seemed to be just her getting used to the sheer scale of her enormous breasts. They were just slightly smaller than her daughter’s, which I suppose was a return to order of sorts.

The thumping moved across the carpet, and the door closed.

Alone, at last. We looked at each other.

“Wanna have a quick sleep?” Anne asked, with a yawn.

“What, so you can kill me?” I responded, with a laugh.

Anne laughed too, for a moment, then abruptly stopped.

“Yes. You fucked my mum, you know.”

“I know, I know! Just…calm down.”

“Don’t tell me to calm down! You had sex with my mum! On my own bed!”

“Only because you weren’t here!”

“Oh, so every time I’m gone you get to fuck whoever you want?! This is bullshit!”

And, slowly but surely, as the argument escalated, Anne’s breasts started to grow again. I wondered dimly if this was part of her plan. I didn’t want to ask.

That would have ruined the moment.
