Sex confession — My hidden thrist to suck

I was asked by a friend if I would suck him off! He came to me, because I’m the only guy he knows who would suck him off, considering my past with giving blowjobs to various strangers! He just broke up and needs some “attention”! I mean I love sucking so much so I can’t pass up an opportunity to suck him off! I mean he has a whopper so….. yes I just don’t know if I should go for it! and what to do.
