A magical visit to my first gloryhole visit

my first glory hole was by accident, i loved dressing up as aslutty girl and going in the toilets to wank off. i was leaning back getting near to my cum shot when a big black uncut cock came through the hole in the wall. i was scared but couldnt resist touching it and the pre cum got on my fingers , i licked it off and it felt so exciting i started to lick the head like a lolipop. i soon had as much as my little twink mouth could hold , it felt so good and then the cock started to throb and my mouth was filled with black seed , so much that i had to swallow to avoid choking . i was in a sort of sexual ufforia and continued to suck this beautiful cock when i felt a little warm trickle in my mouth and realised i was drinking his piss too. i have been a cock sucking faggot ever since.
