I love slapping my cock on my slut's face! It sounds sharp and I get to dominate her. Plus it's a quick break to work back into an explosive cum load all over her face and mouth. The best part is when she does exactly what you did - keep sucking while holding my thick load until she drools it back on to my red twitching hardon. Then comes the ravenous cleanup and the passionate cum kiss. Whew! All from a little slap on her face!
