I do the same, when I'm about to cum I push deep inside right before I let loose. I want her to know that she's going to get soaked inside.
I agree I say go deep into to her pussy and enjoy the feeling of cutting loose.... Im huge fan of leaving my DNA inside a woman's body. Its one of the best feelings in the world.. My wife found that out 1st time having sex with her.. Surprise came to her weeks later.
