Jen hated her body now, all she could do is rub against her massive cocks with what little mobility she had. But there seemed to be a blessing, her now massive balls hid her equine pussy. She had been there for eons it seemed, sitting by that field, her monster cocks always erect, always begging for more. She had managed to fall asleep after a day or so.
Then she was awoken by a tingling on her balls, she wrenched her body to look back and screamed "No!" Snakes, four of them, were working their way toward her pussy. She kicked and wiggled but they managed to get into her and disappear. She felt relived when she saw that nothing had happened, but then she felt her cocks move slightly, they were starting to wiggle and writhe like snakes. "Oh no, no, No!" Her cocks started moving her body forward, screaming under the inability to control them she got motion sickness as her neck started to lengthen like from the fourth snake.
Her cocks were speeding in one direction, cumming again and again as they rubbed on the ground, as if to torment her or even punish her, they were headed for the zoo.
