I was at an ABS a couple of weeks ago. Went into a booth and less than 30 seconds a guy came into my booth and dropped his sweats. I sucked him hard, turned around and had a load in about a minute. Less than a minute after he walked out another guy walked in. I sucked him hard and asked him what he liked. He said he liked to eat ass. I didn't tell him I had a fresh load, I just bent over and let him feast. God, it felt great. He ate me for a couple of minutes and then fucked me too. After a bit he stopped and said he didn't want to cum yet, pulled up his pants and left. He came back later and ate my ass again.
I haven't had the opportunity to felch someone else, but if I get a load, I'll get some out with my fingers and suck it off. As mentioned above, cum tastes better this way. Less bitter, sweeter.
