My very favourite thing has always been having oral sex. It transports you outside of reality and causes you to forget everything. Oral ecstasy is partly dependent on the individual giving you the blowjob. Some are more seasoned than others. As a result, they are unable to make it more satisfying.
My favourite moment is when someone blows you off when you are lying. As though you are in your most comfortable position while the other person is working. Then someone rubs their lips on the head of your cock and when they move deep down to touch her innermost portion of your throat, it feels as though you are outside of time and space. Damn, that is so fantastic. And the most mind-blowing thing is when the other person is lying on the bed with her head slightly lowered and you are fucking her mouth like a pussy, just like when you are doing it back and forth as you are entering the vagina or anal.
I found it to be more fulfilling and exhilarating than sex itself when I experienced it for the first time. Lol. Wonderful experience, that was.
