Puppy Milking Reward - Ruined Orgasm

I was in the mood to play puppy with my slave.. So I put his puppy mask and collar on and walked him around for a minute..  Puppy was well behaved and listed to me, so he deserved a reward..  He gets teased and milked by my skilled hands, but he better not get any cum on me.. Puppy gets to cum, but his orgasm is ruined..
