Ok ladies.. need some tmi advice when it comes to his "precious jewels"

Sabrina • My first love, my son, is 4 years old and now I am pregnant with a baby girl due 12/23/15!!!

My bf has never had anyone suck his balls or play around with them in general. I have never done that to a man either.

Well he wants to try and i love the idea of experiencing it together.

BUT..

I have no idea what to do or how to start or how to do it and im freaking out.

So anyone with experience can you give me some pointers please. 👍😉
