This happened when I was 18 (I’m 19 now). I used to blow my boyfriend (now ex) pretty much everyday and I loved it. I wanted to master the hability of making someone cum with my mouth, and after a lot of practice I got really good at it. My bf never came from a blowjob before me and I could make him cum in less than 5 minutes.
He was pretty proud of me and one day he jokingly said ” Someday I’m gonna have to share you to let somebody else feel how good you are at it” I’m not bragging, those were his exact words haha, but then he confessed that the idea of me blowing someone else just to show how I good of a slut I am was really hot, and asked me if maybe I would be open to try it someday, to which I said that I’d think about it, and I’m not gonna lie, the idea sounded really hot to me too.
