Trained some years ago from a local mistress to become a good c*meating sissysl*t for her. One of the last sessions we did before covid while she still worked as a mistress was to train me to get use to cleaning used condoms from her other clients. Was the most humiliating session I ever did been tied to a chair and ring gagged while she slowly fed used condoms for the next hour and half.
She told me how addict c*m is and that I learn to love the flavors from other mens used condoms.
