BJs y'all

Destani
Okay so I've recently been talking to this guy. I'm into him and he's into me. Either way, I want to suck his dick and he wants me to too.. But the problem is my first experience with someone else was so very bad that I couldn't finish. (The guy I first did it on didn't wash his balls.. 😖) I'm nervous that I'll mess up or something.. Any advice???
