The rumors of the Parasol Corporation doing XXX-Virus experimentations send Jill to an abandoned hospital to find documents and possible vials of an experimental XXX-Virus.
Jill is ambushed before she can swallow her antidote that would allow for a few hours of immunity. Without the antidote, she succumbs to the XXX virus and craves cock and cum begging the mutant to fuck her and let her swallow cum. She manages a mouthful but before she is fully taken a masked hero reaches her just in time to silence the Mutant X, it happens to be Clair who helps Jill recover.
Ada wanted them to check the hospital morgue, and when they arrive see two covered bodies on the tables. Claire hears a voice under a covered corpse, thinking it may be a person in need of help the girls lift the sheet, and you guessed it another ambush, this time it by a creature they have never encountered who spits cum out of its parasitic head attached to the Zombie who it controls.
Clair and Jill are overcome by the XXX-Virus and strip out of their clothes and beg for cock and cum, the monsters are very happy to oblige and let them ride their cocks then stuff their ass's cumming in both orifices.
