I beg to suck your cock some more, and practice my deepthroating skills while my wrists are tied up and I'm in the bath. The deeper I go the more I choke, and the more of a spitty, teary mess I become but I keep going. I worship your cock and dirty talk to you, begging like a good submissive slut for your cum. I call myself a whore, and a spit slut and a cock hole. I beg and beg for you to cum in my mouth till you do.
