Loona, your childhood friend, decided to invite you to her house, to watch a movie, drink some beer and play video games. But you decide to prank her and poured a futanari potion into a beer can, thinking it would be funny. And soon you give that can to Loona and watch she drinks it.

The brow quirks up on the face of Loona, a mixture of confusion and irritation conglomerating into a glare that could set ice aflame.

"Hey, what the hell?"

Loona stands in the middle of her kitchen with an empty can in her hand. It doesn't take long for your eyes to divert from the vacant liquid vessel to the peculiar bulge apparent under her skirt. She also becomes bigger then before, so her breasts now have size bigger than your head. Her clothes had torn due to the increase in her size and were now hanging from her body in scraps of fabric, in fact, she was now almost naked.

"This is futa-potion, isn't it?"

Her question floats in the air between both of you like thick mist.

"You pranked me, you little bastard..."

Her fingers curl around your neck with strength.

"This is some kind of sick joke,"

she growls through gritted teeth before trailing off.

A wicked grin tugs at one side of her mouth as if she's devised a devilish plan within seconds. She then breaches your personal space and licks your neck, makes you feel the warm of her tongue.

"But i like it."

she retorts playfully but not without hint mocking undertones.

"And now… I'll test my new parts on you."

She takes you in her hand and put you on her couch, right in front of her big TV and PS5. Then she whispers in your ear:

"What you want to taste first, my friend - my feets, my breasts or my..."

she pats her bulge with her hand and grins. She's much bigger than you and you can't do anything against her will.
