Amanda crouched over the gun, and turned the height and muscle knobs as far as they would go. The height knob stopped at the 100% mark but the muscle knob reached the 100% knob and kept going. Amanda frowned and kept turning the knob. It kept spinning. "Shit," Amanda cursed under breath. Was it broken? She spun it a few times and then gave up on it. This was either going to work or it wasn't.

Amanda propped the gun up so it was facing her and tried to figure out how to get it to shoot her. Working with a gun that was about a third of your own size was awkward. Finally she removed her belt and wrapped it around the trigger. Bracing her foot against the barrel for leverage she leaned down and pulled at the belt. It constricted around the trigger until, with a loud click, the gun went off and Amandas body was bathed in the glow of the beam. Amanda grunted as the energy slammed into her, she grit her teeth and continued to hold onto the end of her belt. The gun continued to pump energy into her until finally the beam flickered and died out. The gun hummed loudly then powered down with a faint whining noise. Amanda couldn't move, couldn't breathe. It felt like she was going to die. Her heart hammered in her chest and she let the end of her belt fall out of her limp fingers.

"YES! YES! OH MY GOD YESSS!!!" Jess screamed as she came again. Robert continued to thrash his tongue inside her vagina until she wriggled away from him and threw herself across his body. He grunted as the impact of Jess's muscular body drove the air out of his lungs but he smiled as he wrapped his arms around her. "That was amazing babe," Jess gushed as she kissed him.

Robert smirked as he grabbed an overflowing handful of Jessica’s breast flesh. "Yea it was. It's still amazing. This is the coolest thing ever."

Jess smirked and smacked his hand away as she reached down and began stroking his dick. It stiffened almost immediately and her smile widened. Suddenly she stopped and cocked her head. "What's that noise?"

"What?" Even as he said it Robert could hear what Jess had to have been talking about. The sound of ripping cloth. Robert sat up as Jess turned to look over her shoulder.

Amanda’s shadow loomed over them, her massive body filled the room despite the fact she was kneeling. And it was obvious she was still growing. The sound of ripping cloth stopped as the last shred of her t-shirt finally pulled away from her massively muscular chest. The muscles of her body quivered and grew thicker and more pronounced with every breath she took. “Hello LITTLE brother,” she said, her eyes flashing with hatred.

Both of them softly exhaled, "Oh shit."
