Monica screams at Brendon, “Let me down…let me go!! Something is happening to me!”
Brendon puts her down, his monster cock still hard and throbbing. He looks to his girlfriend as another shiver runs through her.
She looks down at her hands and flexes them, turning them over. They both watch in amazement as her forearms and then her biceps swell and tighten with each flex.
“Your cum…it’s changing me somehow” Monica gasped as she reached to feel her breasts swell to the size of volleyballs, standing hard and firm on her chest.
She turned her head to one side, then the other as her shoulders and delts grew larger. Muscle after muscle on her beautiful, petite frame grew and flexed in sequence but not under Monica’s control. Brendon’s seed was controlling her transformation.
Monica’s body continued to flex, her abs becoming totally ripped, her waist nipping in impossibly and her gluts and quads thickening and growing out massively. Her calf muscles were the last to grow and then oddly, Monica bent over in pain. The muscle transformation had not been particularly painful, just very weird to experience. But this was different and coming from her crotch. As Monica doubled over, the pain was accompanied by a strange sucking and ‘gushy’ sound. She opened her legs slightly allowing Brendon full view of her pussy lips growing thicker and longer, her slit started to lengthen up to her belly button and her pubic mound became more pronounced and almost…muscular? Her clit poked out of its hood by a good 2” as it too expanded. Pussy juice dripped down her leg as her massive cunt pulsed, hungry again for the full extent of Brendon’s 16” cock.
The pain subsided and gave way to immense feelings of pleasure.
“It’s massive”, Monica chuckled to herself. Her new body looking like an ultra feminine version of Brandon’s muscular mass. Her nipples stuck out 3” from the huge gravity-defying boobs and she circled them with her small, muscular hands.
“Do you want to try again Brandon?”
