Yup, I seen this in real life. First time I seen it, I was also surprised. I busted nut all over wife's pussy after plowing her. Hub had asked me not to cum in his wife so I busted all over her pussy after pulling out. What I did not expect was for hub to come over immediately after I was done and start licking up my cum off wife's pussy like it was ice cream. It was actually my first time with a wife so I was surprised and shocked by it and I turned away. But since then, I've seen more hubs do this a few more times, and after I busted inside wife's pussy too, not just on top, so not surprised anymore when they do that.
