[MF] Becoming a certified throat-fuckable freak: why do I squirt when gagging on cock?

I have officially topped all my kinky freak charts. I went over to see my Daddy for a cute non-sexual time together but of course I should have known better. We were going to put on face masks and just relax next to each other.

 “Just 15 minutes” he said as he put a Korean sheet mask on my face. Little did I know, Daddy decided that while I enjoyed my face mask he was going to make me cum. While I kept still to avoid the wet mask and all it’s (oil? Moisturizer?) Getting in his couch He went down on me and fingered me. I was only allowed to cum when He said I could, which of course meant I squirted all over his couch. 

Then it was His turn. I’ve really been into being a good service sub for him so I started by giving Him a foot massage. I make an effort now whenever I see him to take off his boots and have started kissing each toe after his socks come off. Lost in subspace I ended up sucking his toes while massaging his feet. I licked from heel to sole- moaning as I was pleasing him- it was so sensual. I worshipped both of his feet before finally moving on to his cock, he was already dripping precum.
