I've licked my own cum, mixed with my wife's juices, out of her pussy. She enjoyed it so much that she came again while I was licking. Although I couldn't cum again so soon I know I enjoyed it as much as she did!
Totally agree... your cum, his cum her cum.... is beyond erotic and to kiss her after you or someone else has cum in her mouth before she swallows is orgasmic on its own.
I'm a male slut. There is no better way to feel true sexual catharsis than to kiss a girl that has your cum in her mouth. The depths of my soul have never felt more relief. I am a very very bad boy. So so bad. Shame on me at last.
