For about half a year Sir will only finger me while his cock is in my throat so I had to learn to cum while gagging on his cock and now I can't cum without it! Even when I masturbate by myself I have to jam fingers down my throat to cum.
Got turned into a Gag-Stool recently! Sir had me chose between getting my throat fucked and getting my ass fucked with a massive dildo. Sometimes he did both at the same time and I came with his cock buried in my throat!
