How many guys cum did she swallow in one helping

Yes I have cum while guys are cumming in my mouth. I’m usually rubbing my pussy or getting fucked when it happens in a group situation
I'm not. Hubby likes watching me suck them only. They leave, we fuck. Rarely more than that. I've done two, but want to do a group. Just oral. It turns us both on. Trying to get husband to kiss me in between swallows, but he's kinda hesitant still. Any suggestions?
