no cum in mouth

Is there a specific position that will make this easier?
Easier to encourage him to cum in your mouth? Don't think so but I really enjoy straddling a woman's face having her suck me and cumming on her face with her arms pinned down. It's a bit aggressive but hot. Especially with a vibrator in her pussy so we both cum together.
 
Ok, I might be missing something. You are a hotwife correct? That means you are married. Why can't you just suck his cock and have him empty in his mouth?
