Your girlfriend comes home a bit distraught saying she got contaminated with the shrinking virus. You try to calm her down but she is very insistent that she has it because she is really horny and her clothes just aren't fitting right anymore. She tells you she want to fuck you until she cant handle your cock anymore as she is overcome with lust. you fuck her in missionary as she slowly shrinks down due to the virus speeding up. She tells you to take it slow at first but tells you she wants all of you in her as she can barley handle it. As she continues to shrink she demands you put all of your cock inside of her even if it breaks her. you cum in the end making her completely full of cum.
