Definitely my favorite way to finish. When i jerk off watching porn and I'm finally ready to make myself cum, I always do so to a man breeding a woman...
My favorite touch -- the guy is fucking the woman, says he's about to cum, and right before he shoots his first stream, he pulls out and lets the first shot go on her pussy/ass, and then puts it in and immediately goes as deep as he can as he finishes.
Absolute favorite? All that I mentioned in the lead-up, pulls out right before he cums, first shot goes on her pussy, then sinks it deep and lets another shot go in her pussy, then pulls out and immediately sinks it into her ass where he finishes unloading. Then he pulls out, she's a good girl and cleans him off, and then she gets cleaned up somehow...I'm a fan of holding a shot glass and catching creampies as they run out so that I can feed it to her.
