A man, usually black, that is married to/dates a woman but fucks men on the side. DL, or downlow, guys tend to be true alphas (aka real men) and those of us who seek them out tend to be very Submissive. For me personally, i seek out guys on the dl deliberately because it makes me feel less masculine if the guy im serving generally prefers women.
Throughout this video, I envisioned what a nice set of titties seemed to be on that white boy, especially in the beginning. I loved how he pushed them out while sucking his man's cock, and then watching them get sucked so well, It all really made for a nice depiction of a true, submissive white bitch-boy and his masculine and superior black master.
