Joe walked into his apartment. He was carrying a box full of what sounded like bottles of liquids and placed it on the kitchen table. He had just returned from the post office and was given this box, despite not ordering anything.

He opened the box and saw it was full of bottles filled with different, multicolored liquids. Jo also saw that there was a note taped to the inside of box, which he read aloud.

"Dear Sir and/or Madam,

I have randomly selected you to test out these potions I have just created. These potions have a variety of effects, so don't be afraid to try them all (or even share them with a couple friends of yours). There's a sheet for you to fill out at the bottom of this box. Enjoy~

Sincerely,

Dr. Tomoko

Joe placed the letter on the table, giving the box of multicolored potions the stink eye. "Well, it wouldn't hurt to at least humor myself." Joe said as he grabbed the first bottle that caught his eyes: a circular bottle filled with a pink liquid.

Joe uncapped the thing and downed the pink potion without hesitation. Joe placed the bottle down and smacked his lips. "Tasted like strawberries." He said. As if on cue, Joe began to feel something. A tingling of sorts

The tingling started at his feet, which began to shrink a bit, becoming more feminine. The same thing happened to his shins and legs which slimmed down, his thighs plumping in the process.

Joe then felt his hips crack and widen to a more feminine size, his butt filling out to match that femininity. Jo then felt the most strangest (and, oddly, most pleasurable) change.

He felt his genitals beginning to tingle. Joe placed his hands on his groin and felt that is was sinking into him. His rod and balls pushed themselves into him, a slit forming where they used to be. His testes changed as well, becoming ovaries, the slit that formed where his manhood once was becoming a vagina. Joe was now a girl.

Joe was understandably shocked by this; but, for whatever reason, she didn't mind it.

Joe then felt her waist pinch inward, giving her an hourglass figure. Her torso, arms, and shoulders gradually lost their mass in order to better fit her new gender. Said mass redirected itself to Joe chest, which began to balloon into a pair of D-cup breasts.

Joe began to grope her new breasts, feeling just how soft and squishy they were. She also felt her new ass which was fairly plump. She also noticed how her new figure made her clothes seem a bit more bigger and more baggy.

This wasn't the end, though. Joe felt her face change to become more female and cutesy. Joe's throat also slimmed down, her Adams Apple vanishing as her vocal cords rearrange.

The final change came to her hair. Her hair elongated a bit, becoming more rounded. The hair on the back of her head lengthened, reaching to her cute derrière.

Joe looked at herself. Because her tits were the size of medium sized cantaloupes, it was a bit hard for her to see her feet. She ran to the bathroom and looked at herself in the mirror. She looked like she came out of some ecchi anime. And she... liked it. She really did.

In fact... she loved it.

...

Joe sat on her sofa and sifted through the box of potions. She was currently wearing an extra large red t-shirt and had her hair tied in twin tails.

She grabbed another potion out of the box. The bottle was in the same shape as the potion she just drank, the differences being that the bottle had a crease in it that made it look like a butt, and the potion was an orangish red. Joe spun the liquid a bit as she examined it. "Maybe this will make my ass bigger?" She asked herself in her new feminine, slightly sultry voice.

Joe uncapped it and downed the entire bottle. As she placed the bottle on the table, Joe felt her butt tingle. She placed a hand on her ass and felt it beginning to grow. It grew to become more plump and squishy, just perfect for someone to grope it. Her thighs thickened as well in order to match her new bubbly ass.

Joe bit her lip and let out a light moan. She groped her ass and thighs, giving it a nice spank. "Now that's what I call an ass," she said as she grinned lustfully, eyeing her tits. "Now let's see if I can make these girls match this butt."

Joe sifted through the box again, looking for a potion that would make her breasts grow. She eventually pulled out a potion that was milk white (fittingly inside a bottle in the shape of a small milk carton). She uncapped and drank the potion.

Once again, she felt a tingling, this time in her breasts. She placed her hands on her boobs and felt them grow. They went past DD's to F's, then H's. Her breasts stopped at I-cups, which were otherwise impossible to have naturally. Joe stared at her gargantuan tits, some drool coming out of her mouth. Joe also heard something. A sloshing sound.

Joe groped her left breast and heard it slosh. She did the same with her right breast and confirmed that the sloshing sound came from her giant tits.

Joe's breasts were full of milk.

"Holy shit, this is amazing!" Joe exclaimed as she groped her giant milk jugs. She removed her shirt (revealing that she wasn't wearing any underwear) and started rubbing her boobs. Her skin felt so soft, the warmth of her fingers making her coo.

She placed a finger on her hardened nipples, rubbing them and making herself moan. She was starting to turn herself on, her breath becoming ragged as she continued to tease herself. Joe then placed a hand on her vagina, inserting two fingers into her slit.

Joe moaned as she began to finger herself, pinching her left nipple to increase her pleasure. She moaned and yelped, tongue out and licking her right nipple. She then started sucking on her right nipple, massaging and squeezing her left.

She started fingering herself again, this time harder and faster, muffled moans squeaking out of her mouth. As she did this, little drops of milk began to drop from her tits. She continued suckling her right breast, tasting her own breast milk. She rather liked it.

Joe could feel her climax coming. She let loose, sucking both other breasts and using both hands to finger herself. She moaned and squirmed and played with her snatch, and then she cummed. Joe opened her mouth, yelling in pure ecstasy as she released her love juices and streams of milk poured from her breasts.

...

Joe walked into her bedroom, placing the box of positions on a table next to her bed. "Well, now that I've had my fun," she said as she placed her large shirt back on. "I should probably go to bed. Should also buy some proper underwear and bra tomorrow." Joe then looked at the box of potions and a lustful smile creeped upon her face.

"Maybe it wouldn't hurt to share these."
