give gemma a boob job

“Hang on, Gemma.” You say. “I’ll help you out.”
You dropped to your knees in front of Gemma and you pulled off your shirt. Your breasts bounced freely in front of Gemma’s cock. You then took hold of both your breasts and pressed them on each side of Gemma’s boner.
“Ohhh.” Gemma moaned.
You then moved your breasts up and down and gave Gemma a boob-job.
“It’s fine.” You thought to yourself. “She’s only going to cum on my breasts anyways.”

Gemma quickly took hold of your shoulders and moved her hips in tune with your breast-movement. He was fucking your tits and you, being extra horny due to the spell, loved it. Before you have only ever had hands touch your breasts to get you off. The feeling of a hard phallus in between them was something new, something exciting.
“Lick it.” Gemma suddenly said.
You look up at Gemma and saw a tortured look on his face.
“The head … lick it.” He said again.
You turned your head down and stared at Gemma’s cock. You saw the purple head disappear into your boobs then reappear from them. On and on, it pushed up, trying to get to you.
You opened your mouth and imagined it trying to jump into your waiting orifice. There was a little drop of precum on it. Somehow it felt inviting, like something you wanted to lick.
You put out your tongue and licked the cockhead. Gemma moaned. You giggled.
You quickly licked it again. You quickly got into the rhythm of licking Gemma’s cock every time it pushed towards you, but it wasn’t enough. You needed more. So you opened your mouth wide and went down on Gemma’s virgin cock.
A shocked Gemma stopped dead in his tracks. But you continued moving.

You wrapped your lips around it and bobbed your head up and down. Added with the continued pressure of your bosom, you could sense that Gemma was getting close to orgasm.
“Good.” You thought. “Better to quickly turn Gemma back into a girl, then to let her remained guy during the night.”
When Gemma got over the shock of you sucking him, he went back to moving his hips. He was now fucking your mouth and it only made you hornier.

Then, without warning, a warm liquid shot out of Gemma’s cock. You wanted to pull away, but Gemma had put his hands on your head and prevented you to pull away. Quickly more and more of Gemma’s sperm filled your mouth. You couldn’t quite think but your automatic response was to swallow … so you did.

You swallowed all of Emma’s salty essence until he let you go. Both of you fell backwards and caught your breath.
“Oh god.” Gemma said. “That was amazing.”
You would have said something similar, but you noticed Gemma remained a guy, and his cock stayed hard. Just like you, he’ll be needing several orgasms to turn back into a girl.
