I went down on a mature black guy once. Had a huge dick. He warned me he had never been able to cum from oral. He had to fuck. I went to work on that big dick and within a few minutes he grabbed my head and began fucking my mouth furiously, moaned out loud and blew a massive load down my throat! I drained him and kept working on it while he caught his breath. Ten minutes later he blew another load in me. He changed his mind about oral!
