RUN JOSH RUUUUUUN

As josh wriggled on the tremendous cock head of his little sister he noticed her let out a little moan.

“Mmmph, Joshy, I’m trying to focus on these enormous nipples right now but you are just moving around too much!”

Liz began playing with the tips of her nipples, as larger flow of milk came spraying out, sharp and focused, like a hose that was blocked, her former pant legs making stretching noises as the nipples got even harder. Watching her brother, who was once, to her, imposingly huge, struggle to sit aloft her penis that was now a couple feet taller that him, was causing her to get increasingly turned on. She loved being so big, and unfortunately the prospect of getting bigger was the biggest turn on. Her blood started pumping, her pulse quickening, and her dick started throbbing.

“L-Liz! You hafta calm down!” Josh said, slipping slightly and having to scramble back up, the throbbing of her 8 foot dick was making it very difficult to stay aboard, and his foot movements along her tremendous girth was making things worse. He was now grappling with the glans, gripping the opening of her cock head.

Mistake.

Liz gasped, and a spurt of cum shot out, spurting her upward 4 inches. Her muscles bulgin slightly, and her breasts inflating.
