Got a message from my ex yesterday morning, asking when I was up for my next poz dose. I quickly replied and headed over. I only made it through the front door and closed it. He ripped my pants down, planted his toxic poz cock deep into my hole without any lube and proceeded to fuck me like there was no tomorrow. After a few minutes he growled into my ear "take my toxic pox load" and then I felt that familiar sensation as he flooded my neg ass with his toxic load. I went home, my neg boyfriend, who has no idea I'm chasing, told me to go wash, I knew I was full of toxic cum. I quickly rinsed and presented my ass for it's next load. He too fucked my ass and left his neg load behind to mix with the nasty load already in there. The thought of him getting pozzed up by the toxic load in my ass makes me so horny
