Humiliation and domination. It's a perfect way to display their dominance, by hate-fucking our mouths and asses. And we submit, first without serious resistance, then willingly, then eagerly. My Ex's big bull boyfriend, after making me suck his cock with her as an audience of one, then took great delight in fucking me brutally, again, with her watching, and laughing at my reaction; pain, discomfort, then moaning to an orgasm after 15 minutes of his long black cock massaging my prostate and ramming into my colon. I was hooked, but after three Saturdays of torturing and humiliating me, he lost interest. He invited his 63-year-old uncle to participate, and turned me over to him. That's when the real fun began. Uncle had been recently released from a 12-year prison term for assault, and had become an expert at fulfilling his desires for sex, and revenge, upon same sex partners.
