It was over a year ago and it was with my first girlfriend, she was quite a few years older than me and had tons of experience. she went down on me a couple of times and it blew my mind (although I had had guys go down on me before that, but it didn't compare). i was nervous when she asked me to go down on her, but i was also so excited and it made me sooo horny just thinking about doing that it was my first gay sex experience i guess. her pussy was gorgeous, and i devoured it. i've never looked back...
