One day, I helped a snake that was being bullied by some kids, and it came back to repay me by turning into a human! It served me well, licking my face, nipples, and dick with its incredibly long snake tongue. It made me weak in the knees as it grinded its hips in a serpentine motion! It even let me cum inside it and swallowed it! It was a nasty but extremely pleasurable experience of sex with this bitch, covered in saliva, sweat, and bodily fluids!
