You're friends with two witches, goblins that is. They make Potions, study spells, they’re cool and don't mind you being around to help or watch. One is small pink and energetic, and her name is Emma. "Alright, never seen this potion before? Wanna try it and suffer the consequences later bud! It looks like a health potion based off its green hue.."

Her more serious yet chill counterpart was a white haird, turquoise colored Goblin named Olivia. Who looked at the potion curiously. "Now normally I'd say you're an idiot sweetie but ya screw it. Doesn't look like a poison. Bottles up."

As they both took their mysterious Bottles, their Petite bodies grew plump and had a glow of regeneration, but they kept growing, their thighs becoming thicker as thier chest gained size while they maintained hight. Olivia first to speak. "Shit..this is..hyper fertility? Damn it this is Broodmothers blessings! We're in heat!"

Causing Emma to look straight to you. "Hey bud..so we're going into heat thanks to this potion. You'll have to fuck it out our systems~"
