My first cock sucking experience Black CD/Transsex

Then I knew. This thought raced through my head. Oh my god, you love this. you love sucking this cock. Are you gay? Does it really matter? I knew that this would happen again in my life because I had never been more aroused and in sheer lust that I can remember before.
I asked her if we could 69 not knowing anything about this two cock scenario and she said yes. I got down on the bed face up, while she pulled one leg around and straddled my face from above. I remember feeling her thighs and thinking how tight they were as I was used to womens softer body. But the cock drowned out my judgement and soon her cock was in my mouth and pushing through my lips downwards into my mouth.
It wasn't long though and I remember my urge to cum came up on me so quickly that I told her that I didn't want to cum yet so can we change postions and she said yes.
So she laid down face up with her legs open wide enough for my body to rest in between her legs as my cock just lay against the bed. It was throbbing and I felt as it the slightest movement was going to take me over the edge. I sucked on the cock from this new angle and again loved the velvety smooth cockhead skin and the cockhead seam and folds of skin. I remember just moaning with pleasure as I felt like I was breathing in years of cock lust for the first time and going for it.
I continued to suck as best as I knew how and began to feel the urge to cum. I tried to hold still several times over and over again while sucking, but the minimal movement of my head bobbing and neck and the sound of my mouth all slippery and splashing saliva into my mouth. hearing my mouth open and close around this beautiful cock and hearing my breath around it. The sound that emanate from my cheeks and mouth as I sucked a cock further reminded me of the porn I had watched so much. Watching blowjobs of girls sucking cock always secretely wanting to be the girl. There is a sound to a blowjob that could get me off alone. Here it all was in front of me. My mouth starting to tire a realization also , knowing how much cock sucking I have watched realizing that cock sucking takes effort as much as I loved it.
