my wife really doesn't mind kissing after oral.she doesn't like to swallow(weak gag reflex),and it's more stimulating if she just uses her tongue and lips when i cum.i'll kiss her.it really is very sexy.she likes to watch me cum,and i've even lapped some up and put it in her mouth when we kiss.penetration,oral penetration,makes it last.yum!of course we've been married 10 years.works for us.
