"Ooh God wait your too big. Ooh shit!!" she screamed. It was true, his cock was stretching her pussy so much it must have hurt like hell, I could see ...er lips stretched tightly around his black shaft but he pushed on relentlessly."OOOOhhh GODDDD, OOOh Christ your splitting me in half!!" she said in a high pitched voice in real pain but he humped harder until unbelievably he had his whole 10 inches imbedded into her wet pussy.
