Your life is changed forever.

Heather goes over to Simon's house, and you stealthily follow her. She goes inside, and you see a few friends of hers and Ms. K waiting for her before the door close. You sneak around the back of the house, and carefully spy them all going upstairs. You wait and confirm that the rest of the rooms are empty of people before you enter through the backyard.

But you only manage to make halfway to the staircase before suddenly Ms. K grabs you from behind!
"Welcome, John, I've been waiting for you."
You suddenly feel very tired, barely capable of standing. The black MILF walks over to the living room sofa and sits you down.
For some reason, she immediately starts pulling your pants and underwear down. You can't stop her, you don't have the energy. She giggles as your miniature willy is exposed to the air.
"I knew it! You never tried anything with Heather because you can't satisfy her, right?"
"...Yes..." You admit in defeat.
"Then I guess this won't be much of a loss, since you weren't much of man anyway!"

Ms. K snaps her fingers and that is when it all starts...
You suddenly become blinded by a bright light as a great wave of pleasure wrecks your body.
You pass out for a minute, and when you come to, Carl is standing in front of the both of you...naked! In between his legs stands a meaty and long monolith, and a big pair of veiny balls. For some reason, it makes your mouth water...
"So who is this lovely lady, mom?"
Ms. K stifles a laugh, "Her name's Penny. She's our newest recruit!"
"She a virgin, too?"
"Yep. Give her that big black cock, son!"

Suddenly, you realise your body has changed...into that of a well-stacked woman!
Not only that, but her pussy is hot and wet, ready for action! Carl shoves his erection straight into your face.
"Suck it!" He commands.
You...you can't resist. You lean into his crotch and try to swallow it all whole. The heat and pre-cum fill your mouth. You lick and suck for half a hour, but he still doesn't cum, despite moaning up a storm from the pleasurable worship.

Eventually, Carl pulls out of your mouth and flips you around. He angles you just right, and...
He slides the tip of the head up and down your soaked pussy lips, you yelp with excitement. Then, he stops at the mid-point and begins slowly advancing forward. Your labia momentarily resists his advancement but quickly yields, the outer lips folding inward as he advances.
You moan this time, a deep guttural moan, as Carl's dick goes past the labia and enters your vagina. Carl rocks the head of his cock just inside the opening, your soft lips disappearing with each short stroke. You respond with short deep barks in rhythm to each of his strokes.
You can feel the vibrations of that monster all throughout your body. Your boobs jiggle frantically as he shoves in and out of you. He's taking you, making you his bitch.

Carl inches himself in deeper, allowing your pussy time to stretch and accommodate his huge, thick weapon. Your moans grow loader and longer accordingly. As soon as he reaches a new depth and your pussy is ready, he pulls out to just beneath the tip, then drives it straight back in one quick thrust. He does several of these thrusts before stopping inside and pushing slowly in another inch. He repeats this the entire time. By the time he's half way in, your breathing has become much shallower, like animal panting, as you grunt and whimper. Carl begins a series of strokes half the length of his cock.
Ms. K cheers him on as he plows you into the stars.
"Make her forget all about those pindick whiteboys! Show her what a big dick can do!"
That does it. Your stretched pussy shudders as it squirts, utterly charmed by this black stallion. Carl follows suit, creaming your pussy utterly.

Just as Carl walks out, satisfied with his work, Heather comes in, wearing little.
"Heather! Come over here, meet our newest recruit!" Ms. K cheerfully pats the spot besides her.
"Another girl, huh? Nice big tits. Let's see if your pussy tastes as sweet as the others..." She purrs as she drops in front of you, ready to lick at your pussy.
"Heather, it's me! John!" You plead, shocked.
"What?"
"John tried to sneak in. I caught him, and...adjusted him, for everyone's sake." Ms. K explains. "Heather, he had too little a prick to be your boyfriend...so he's your girlfriend. And a member, just like you."
She looks at you quizzmatically. "Is that true..?"
You nod.
Heather grins ear to ear. "Perfect."
Ms. K hands her a large and jet-back strap-on. "Why don't you two enjoy your first time together..."
"Oh, this is wonderful, honey!" She squeals as she puts it on, "We can fuck huge cocks together! You're gonna love it!"
Heather strokes the huge black strap-on as she prepares to penetrate your cunt. Not only has she had more women than you, she has a bigger dick than you did as well.
"I love big dicks, John, and now you will too."
You scream that you love her as she fucks you. In and out, the plastic cock goes, as you kiss her with lots of tongue. It's not what most people would call making love, exactly, but it is a full hour of hot, tender, juicy action, ending in you both licking deep into each other.

When you're finally done, Ms. K claps her hands together, "I have one more gift for the both of you..."
"What is it?" You ask.
"This." She says as she snaps her fingers and a bright light fills your vision for a few seconds.
When the bright light fades, you joyously grope your chest to find that your boobs are now even bigger - they're massive, soft and round. And so are Heather's. You pull her in close and tongue-kiss her passionately, your cantaloupes rubbing deliciously against hers. What a sexy, stacked duo you are!

From now on, you and your girlfriend serve Ms. K and The Mandingo Society as their resident big boobed sluts - titfucks and double blowjobs on demand for the well-hung men, and pussy licking for the chicks. Ms. K provides the happy couple with room and board at the club's manor in the mountains, to better pleasure the members' members. Your love only grows stronger now that you're both bisexual busty babes blowing big black (and Asian) willies! Every day starts with a 69, before you spend the morning sucking huge cocks and feeling them jizz in your deep cleavage. Every night, Ms. K fucks your pussy and Heather's with a strap-on. Simon comes by the most, he really digs it when the two of you get all four hands on that gigantic 12-incher, and coax multiple loads out of it. Who knew that a short Chinese guy like him had such a massive dong? He even manages to completely coat your titties with sperm, despite them being large enough to completely swallow his tan pussy-pleaser when you tit-fuck him! The other girls come by occasionally, too. Heather was right, getting fucked by a hung stud is awesome!

Two years later, Ms. K tells the two of you nymphos that she needs you both to carry out a special duty to the Society. Do this, she promises, and the reward will be great.
