Invasion of the Grannysnatchers

A parasitic virus has been going around infecting every woman over the age of 40. Turning them from dutiful wives into lust crazed zombies.

You return home from work to find your roommates hot Japanese Grandmother squatting on your bed. She’s been infected, you can see it in her eyes.. glowing red/pink with want and desire. She was waiting to surprise you. She’s ready to pounce. She’s unnaturally fit and nimble for someone her age. The virus enhances the hosts body and sexual capabilities.
