[M4F] For 2020, the year of anxiety, an anxious blowjob!

I think it’d be fun to roleplay receiving an anxious blowjob. What makes it anxious? Not knowing the ending! It could be really good, or really bad, or somewhere in between; but I’m already in too far to pull out.
Blowjobs (and handjobs) come with a lot of risk if you don’t know your partner is committed to your having a good time. Yeah, your dick feels great, but it’s also easy to slap it around, or worse, bite down! Then, there’s a fragile pair of balls hanging right below. They make your whole body tingle when fondled. They also make you beg when squeezed.
Most of my ideas involve a partner with conflicted motives.
\-A rich man paying for time with an unknown call girl, who knows he’s got a lot of cash on him.

\-A couple who just made up after an argument.
\-A one-night stand between two people who didn’t communicate enough beforehand.
