You’ve had this fantasy for years. Being helpless, small, with a sexualized body that no one will be able to ignore. Dependent on men, both in your normal life and in your sexual one. A captive of your own body and urges, an animal in heat. That is what you’ve always dreamed of.

The witch didn’t even blink when you gave her the money and told her what it is that you wanted. She’s probably heard hundreds of similar requests across the years, you think.

“The potion.” She said, giving you a small vial. “Take it at night and you’ll wake up in your ideal body. When you’re satisfied, come visit me and I’ll give you the antidote.”

When you wake up you instantly feel different. Your posture is all wrong. Your body feels weird. There’s a heavy pressure in your chest. You don’t even have to look down to see them. Two magnificent breasts, each capped with a perky pink nipple obstruct the view of your lower body, even when laying down. You try to get up and struggle. Your pendulous orbs swing from side to side, and you almost fall back down before catching your balance. Your shoulders feel tense. A small price to pay for the most perfect pair of breasts you've ever seen.

You look into the mirror. A short pixie cut of mousy brown hair. Small, button like nose. Brown eyes. And you’re so tiny (except for your breasts, of course!). What are you, 4' 11? There’s no way you’re five feet. Getting things out from the pantry will be almost impossible.

A heat in your crotch follows that thought. You feel yourself getting wet. The helplessness is turning you on. How many things that you were able to do easily as a man will be impossible now? Your breath gets short, you start to sweat. There’s an emptiness in your stomach. A shakiness in your hands. You try to calm yourself but it’s impossible.

You need a man. Now. There’s nothing more important for you. How can you live, how can you even survive without a big, strong man taking care of you? You need a pair of big, strong hands hugging you, caressing you, moving from your neck to your collarbones, down to your breasts, making circles around your puffy little nipples, getting hard as diamonds, down to your stomach, where the fire grows and grows, until finally it reaches the treasure between your legs and…

You catch yourself with a hand caressing your labia. Did you ask for this level of horniness? Surely, it must be a mistake. Maybe the potion was faulty. You need to correct this. You need the witch. This is too much.

Unfortunately, you didn’t think about the fact that you lived in an apartment with a roommate.

Your first time is pure ecstasy. Bent down on the coach, taken from behind. Your big, sexy naturals making it so it is impossible for you to lay flat. He takes you hard and the roughness makes you lose your mind. Your breasts are rubbing nonstop, getting chafed and red. When you think you can’t take it anymore, he slaps your pillowy ass and you scream. So good! Your moans encourage him to continue with the spanking. Being the mischievous little slut that you are, you try to cheer him on with actual words.

“So good! Spank me! Spank me! Pinch my nipples! Rub them! Oooohhh.”

You feel him coming inside you and you faint.

Months have passed now, and you know how helpless you really are. You are the perfect, devoted girlfriend. When you’re not pleasing your man, you’re thinking on new ways to do it. You live to serve, nothing more than a pair of breasts and a pussy to feel pleasure.

And what a pair of breasts you are! While fun during sex, they are much too big for your tiny frame. Your back aches constantly and you need to get your bras from special shops on the internet. Even if your sex addiction let you out from your house you would not be able to walk more than a block before you were exhausted. And it’s not only how tiny you are, but also how weak! You are sure that other girls your size do not have the trouble you have lifting objects or trying to complete your chores.

And still, after all this time, it’s still you. Behind the uncontrollable urges and the ditzy, giggly airhead, it is still you. A man. You cry when you’re alone. There’s a void that needs to be filled, constantly. Being left alone scares you. You whimper and sob and cry in withdrawal. There’s only one person for you. You would never, ever think about cheating or leaving your boyfriend. Or about changing yourself back.

You were never able to contact the witch again. The thought never left your head, but it became an impossible task. Being alone leaves you a whimpering mess and being with your boyfriend means constantly trying to please him while trying to satisfy your never-ending lust.

And when you hear that door open, all fear and sadness will leave you. You’ll lay on your back, empty smile on your face, hands on your giant breasts, waiting for him, a plethora of sexual noises coming out from your mouth. You know what you’re made for, and there’s no escaping that.
