"Oh my God!" Jess exclaimed as she could feel the energy rushing into her body. "Yes! YESSSS!!!!" Robert grinned as he watched his girlfriends body changing. If she was buff he wouldn't have to worry about hurting her, and he had made her taller, hopefully tall enough so she could take his monster cock, but not anywhere near tall enough for him to have to worry about her overpowering him.

Jess ran her hands over her body, feeling the changes, watching the changes; she had never been this horny in her entire life. "Oh God, this is amazing!" She shrieked as her breasts pulsed outward, overflowing her hands as she kneaded at them. Her biceps quivered, become ripped and vascular in seconds. Her shoulder widened, swelling outward as her delts grew rounder and thicker. Her abs were rock hard and her legs looked like marble columns, and still she was getting thicker and harder.

"Robert," she yelled, "Fuck me. Fuck me now while I'm still growing. I want to feel you inside me!"

Robert moved to her, taking her into his arms and wrapping his arms tightly around her, he could feel her body getting harder and larger, pushing against him. His massive cock twitched as her body rubbed against it. "C'mon baby, put it inside me, c'mon." Jess breathed in his ear, her breath hot and damp against his skin. She got on her hands and knees, raising her dripping pussy towards him. "Take me from behind, take me hard."

Robert grabbed her hips and rubbed this tip of his penis against the lips of her pussy, making her squeal with anticipation. Then he started pushing; slowly he pushed himself into her. She was big enough to take him, barely. It was the tightest, the hottest, and the wettest fuck Robert had ever had. Jess screamed with passion and lust as she was filled to the utmost, her pussy stretched to its limits and then some. "Yes, baby, yes! Fuck me!"

Robert held her hips tight and fucked her. He thrust into her hard and fast, still feelling her muscular body fill out under his hands. Jess’s brain was overloaded with the feelings from the sex and the growth. She screamed as she came, a primal release of emotion. And she kept coming as Robert continued to pound her like a jackhammer. His huge rod rushed in, it’s thick veiny sides rubbing hard against the walls of her vagina and his balls slapping against her as he bottomed out, the tip of his penis pressing into her so hard it was painful. But the pain was nothing compared to the rest of what she was feeling. She screamed again as she could feel Robert blowing his load inside her. Without warning she got up and turned towards her titanic boyfriend, grabbing his still pulsing dick and placing it between her breasts as she began to tit fuck him. He moaned with intense pleasure and fell back onto the bed while Jess squeezed his dick between her breasts and sucked at it, his tick jizm running from the corners of her smiling mouth.


“This was it,” Amanda thought to herself as she watched the two of them fucking like crazed animals in heat. This was her chance to get the gun from the middle of her brother’s floor where he had dropped it. Amanda slipped into the room and silently began stalking towards the gun.
