Multiple Cumshots

Recently turned 18 and open for more sexy ideas. 22yo bf and i talked about the idea of having guys jerk off to me and cum on my face. If multiple partners aren't readily available then we would find more men with the sperm still on my face. I'm a very petite girl (4'10) and i already feel intimidated being on my knees in front of a guy, the idea gives me butterflies. The good kind!
But whenever he's not watching... I plan to even stroke and suck their cocks whenever possible. He didn't agree to that but i will do it anyway.. when he's not looking.
