Sub gets fucked to the limits

Is masochism the inability to enjoy other thain in pain, or the ability to derive pleasure from pain? I love it when I’m pushed to my limits. Being fucked long after I already had several orgasms…. until I can’t take it anymore. Like a obedient sub I lay down and allow you to do with me everything you want. Would you punish me with orgasm denial or will you fuck me until I scream your name?…
