Miss Patriot's powers desert her!

Alex loved the feeling of that big black cock inside her little pussy but she knew she shouldn't. 'Oh god,' she moaned, bouncing on her breasts. 'Do you know who I am?'
'I know exactly who you are,' he said, clamping his big hands around her throat and thrusting hard from behind. 'You a dumb little blonde girl who about to get a black baby in her belly.'
Alex's eyes opened wide with horror as he choked her: her superpowers required a steady flow of oxygen into her bloodstream! She struggled feebly against the onslaught but was powerless to resist him. She realized she was reduced to nothing more than a schoolgirl... one who was about to be bred!
