Another old thread brought forward here... but it allows me to answer... YES!
My first experience to satisfy my "bi curious" side was a threesome with a gay couple. I was their boy-toy gay virgin, and they were excited to show a "straight" guy what male sex is like. It was an evening of pleasure focused on me.
I was massaged, caressed, licked, sucked over every inch and orifice of my body. I got to feel and suck my first cocks, one of them was a meaty, thick one. I will never forget the feeling of it swelling in my hand as I stroked it to erection! It felt amazing compared to my own slender shaft... a mighty oak compared to a sapling! I loved the feel and look of a big cock! I still crave it!
I had my first blowjob to completion. One was very talented and was able to easily deepthroat me. I never had that done before! It was cool to see my shaft disappear in his mouth down to my balls! He sucked me to climax and sucked and swallowed every drop of my cum.
I was eventually fucked by the thick guy. He pounded me mercilessly! I was happy when he finally came because he had me bent over the bed and his body slammed me so hard with each thrust, it was uncomfortable! Not inside, just the body slamming externally!
It was quite an experience! I had another MMM threesome some years later, but the first is the most memorable for so many reasons!
