I do both, depending on the situation. One friend was such a huge cummer I could not swallow it all and it would run down my arm. Sometimes I wanted to watch him cum. I miss him. Otherwise the few guys I have been with seem to absolutely love it when you stay on him and suck the last drops out. I realized that with my third girlfriend in high school. She only let me out to watch and rub her hands all in it and over me. Otherwise she swallowed and always smiled so sweetly. My wife has never swallowed that I recall. I will take it either way, thank you.
