I've been with black men many times. The first was 9" and a fantastic lay. He bred me on two different occasions and I was in heaven both times. The second top who bred me was 13". I didn't think I could take it, but he was gentle and ended up riding me balls deep. Just when I thought he was done with me, he put a collar on me, tied my arms behind my back and chained my collar to the floor. My ass was in the air and he called his buddies to come over....four other black men. The smallest cock was 10". I didn't like the helpless feeling and was scared shitless about what was going to happen to me. They fucked my brains out for the next several hours, five black guys taking turns mercilessly fucking my ass and cumming in it over and over again. When they let me go, I understood what the walk of shame felt like. My ass was leaking cum for two days. I think about that day over and over again and wish it would happen again. I love being a cumdump.
So, to answer the question, yes, black men are awesome tops.
