Joce grinned evilly. Peter was asleep, he looked peaceful but Joce didn't get a wink of sleep. All she could think about was growing him, making him a beast to fuck her into unconscious, her pussy was wet just by thinking about it.
Time for him to grow.
Peter didn't realise what was happening to him would change him forever. His heart started to thump harder. More veins pushing up against his skin.
Joce knew a way to wake him up, she grabbed his cock which was becoming thick and began to stroke. Peter's hips began to buck. Alright she though and imagined him monstrous.
"FUCK!" Peter shouted, waking up as his body gave a burst of solid muscle growth. His hands went down to his dick and he began to hump the air widely, hormones out of control.
"J-Joce? Uh, can't control, Uh! This. I n-Uh! need you UH UH!!!"
She giggled positioning herself over his cock "Do you want more Peter?!"
"Fuck! YES! FUCK ME!"
Joce moaned sexually at Peter's new commanding tone. This made Peter whimper with lust.
"Understand this Peter, every pump your muscles will grow larger. Don't stop!"
Then with that she pushed herself into his brick hard cock. She screamed as Peter let out a beastly roar. He pumped into her and with each thrust his muscles exploded with size.
"More! Don't stop!!!" Joce cried, flinging her head back in ecesty.
"FUCK! Ugh! UGH!! Yes! YES!" Peter snarled.
This was something else, she had never made him feel like this before, he'd never felt so alive. His biceps were giant, flexing, veins pulsing with growth and power, same goes for his pecs and the rest of his body.
He was becoming a giant that's only need in life was to grow and fuck.
So he kept on, even following her wishes in-till she was unconscious but he kept on fucking and growing.
