Everyone in your village is passing from the plague. You’re good and trusted friend sends you to a doctor who has interesting ways of healing people. You get there and she ominously asks you to follow her. You’re confused as she starts to undress, but explains that she has a magical pussy that can only heal a small few from the plague & that there’s a reason you’ve been chosen to live. You have a wife and kids, you don’t want to cheat. She explains that your wife and kids would be happier to have you there to be a father and a husband. She needs you to consent so after agreeing she starts riding your cock and you feel your strength slowly coming back the more she rides you. Once you cum inside of her and all the illness has been sucked out, you feel cured. She asks you to leave before anyone sees because this must remain a secret, no one can know of her special gift.
