Personally, I love kissing my wife after I've filled her mouth with a nice load. I remember reading an article by a very well respected sex columnist that suggested guys whose gf's are put off by the taste/smell/consistency of their ejaculate should grab a spoon and dig in themselves to see how they like it. :D After reading that I realized I should never ever belittle the act that someone has been so kind to perform on me by refusing to kiss her afterward. I didn't expect I'd like it so much tho. :)
We do a routine where my wife basically gives me a bj, then right as I'm cumming and after I've sent 2-3 solid spurts in her mouth, she changes positions really rapidly to jump on top and get me inside her and rides me really really hard and fast while I'm still cumming (gets her off immediately). Usually, while she's riding me hard she's kissing me hard and - because it really really turns her on - she hasn't swallowed a drop yet. To her it's almost like a 3some that she has cum inside her and in her mouth simultaneously, and it drives her wild. This is just a little personal game we play, but I thought I'd share with those in this thread who are on the same wavelength as us. :)
