Damn, That felt great!  I have not shot my load in four days, so my nuts were full. It’s OK that you were not able to swallow it all, I understand that was a lot of cum shooting into your mouth all at once. Since this was your first time sucking cock, we will let it slide.  

I must say you did a pretty good job getting all ten inches into your throat, and no teeth scraping, you are a natural at this. With a little training you will be able to take it all, with no spillage.
