That night it was announced on telly that an alien space craft had hovered over a tower block of flats sending flashes of light into it and that the block was now under full quarantine and sealed off. Scientists were trying to work out  how to deal with the sex mad residents of the block who had developed a strange strong sex urge and were having sex with any body and every body but only fellow residents. July was happy as she saw another spurt of cum having lost count of the amount she had seen.
