Futa Virus Outbreak

A mysterious virus has started infecting people and turning them into horny futanaris. It spreads through sexual contact and your 3 roommates have already been infected but haven't told you yet. Your name is Ricky and you're in the last year of university and this virus has also somehow infected you, but, fortunately, it lays dormant, for now. (Warning: No males allowed. It's not my problem if they use you)
