Futa potion? Count me in!

"Y-yeah... I choose this one." Kruya looks at you with a serious face: "Are you sure? This only works if you do not have a penis prior use." You realize that she must know and look at Pearl who has her mouth open: "M-March, I'm ok with this, please let me drink it, please?" She sounds almost **** and you gulp as you start thinking about it.

"I-I have a penis Pearl, is that ok?" You manage to say it and breath out already exhausted. "Yeah, yeah. I'll drink it, ok?" You are surpised by her reaction and just give it to her. She stops and looks at Kruya who is blushing. "Hey, Kruya... What if I don't drink it all, but only half?" Kruya fixes her glasses and answers: "Well, the total mass of the organ will be half of the total, but it should work just fine, are you implying something?"

Pearl is bright red and mutters: "Wanna try it with me?" Kruya almost trips as she backs away and hits one of the various boxes strung about. "F-for science, yes!" She says beaming and Pearl looks at you happily. You give her an unsure smirk and she takes a gulp of the pink liquid.

She hands half of the bottle to Kruya who downs the rest of it. You feel nauseous and sit on the same couch you sat in at the very begining with Pearl. Pearl smiles and sways around waiting for it to take affect. Kruya pulls her pants down and panties too. You watch as Pearl suddenly winces and doubles over. "Nggghh! It hurts, oh fuck, it hurts so bad!!" She screams and holds her lower abdomen and cries. You take her and hug her on the sofa as she cries and a little bit of a buldge starts to form on her pants.

She pulls them down while Kruya is panting and ass up on the floor on all fours. There's a little tiny bump on Pearl's panties and you can't believe it. She is crying and pulls her panties down making the one inch micropenis reveal it self. It's thickly covered in foreskin and it doesn't even look like a propper dick. She screams and hugs you again as the penis starts shaking and Pearl's moans turn exhausted. Pearl whines as the penis grows an inch and you gasp.

Pearl holds your breast as her limp body shakes again and another inch makes the cock start to look like the real thing. "It hurts so baaaad!!" She cries and holds you tightly as her wet face ruins your shirt. She screams and the penis grows and inch again. While all of this is happening Kruya is panting and grunting to get her penis out all the way - she doesn't react to the pain as severily as Pearl does.

"It's coming out, oh fuck, hold me March, AAH!" She wails and the cock grows another inch, now at 5 solid inches it starts to ease down and settle. You are almost as out of breath as she is and her breathing starts to get easier. "M-March, I have a p-penis..." She touches her erect 5 inch dick and it reacts as you would expect. "I-it's so sensitive, I can't take it March, ah..." She moans and hugs you again.

Her penis brushes on your thigh and splurts out a load on your skirt. Pearl is whining and shaking as her penis starts getting flaccid. "I-I'm sorry March! I ruined your dress with my... oh god!" She runs away and you get a quick look at Kruya who is just about to cum with her 7 inch cock on the floor.

"Oh no! Don't looook!!" She ejaculates and white spunk dirties the floor, she is bright red and her breathing is sharp. You are painfully hard yourself and just go, just follow Pearl, who is running her soft penis flailing. She runs in the bathroom and washes her face. "Don't you dare say anything! I'm sorry ok? Sheesh..." She's mad for some reason. And you just pet her back.

"I-it's ok. It's hard to realize the fact that you have a penis, when you are obviously a girl. I know that too well." You say it like you're her grandmother and cringe. "I-I am a girl... M-my penis is just... It's just..." She takes her hardening cock in her small hand and rubs it. "It's funny feeling, and really hot too... I want to use it."
