When I met Sir A., an incredibly dominant alpha male with a thick, uncut cock, I knew I had found someone who would truly challenge my limits as a submissive bottom guy. One of the most memorable moments from one of our encounter was when he decided to test my deepthroating skills - something I'd never attempted before and was honestly terrified of.

As I opened my mouth wide and began to take him in, I could feel my heart racing with a mix of fear and anticipation. Sir A.'s cock is just too thick for me - or so I thought at first. The sensation of his erect member sliding against the back of my throat was intense, almost overwhelming at times, but it was also incredibly arousing.

But as the minutes ticked by and my determination never wavered, I realized that this was going to be much more challenging than I had anticipated. My throat got sore from the gagging, and there were moments when I struggled just to breathe with his cock blocking my airway.

I pushed myself harder than ever before, determined to please Sir A., even if it meant suffering and struggling in ways I never thought possible. And while I wasn't able to take his whole cock in my mouth - not yet, at least - the effort and dedication I put into this experience proved to him that I am not only a submissive bottom but also a determined and committed one at that.

This experience was both humiliating and incredibly rewarding - just like any good deepthroating session should be. It showed me how far I was willing to go to please Sir A., and it proved to him that I am up for any challenge he throws my way.

I can't wait when we'll push the boundaries even further and explore new depths of pleasure and submission together.
