SUCKING A STRAIGHT GUY

I was drinking pretty much with my good friend Mark, who had been Anita’s boyfriend before we get married.
During a nice discussion, the main subject was finally about blow jobs…
Mark said that girls were good giving head; but I insisted that the best head could only come from a guy.
We went back and forth on the subject and Mark eventually confessed that no girl had ever made him cum from just giving head, including my sensual wife Anita, who was not a good cocksucker, according his opinion.
Sensing the opportunity was coming, I told him that I could make any man cum in less than ten minutes, just sucking on his cock and giving him a proper blow job.
After Mark protested my claim a few times, I told him I could prove it.
So, he unzipped and dropped his jeans and settled back on the couch. He was sporting a nice semi-erect bulge right there.

Then he clicked the stopwatch on his phone to start the counter and I got down on my knees between his legs. I started by putting my mouth to the growing bulge in pants, kissing and sucking over the thin fabric, It only took a minute before he was fully erect and I slid his undies off to get better access to his throbbing cock.
He was really massive, nine inches and it was not even hard yet.
I licked the head, running my tongue around the girth of his cock. It tasted a bit salty and I knew I had to have that cock deep in my mouth. I slowly put the tip in my mouth, my lips firmly around his shaft as I flicked the head with my tongue.
A soft moan came out from Mark’s lips. I could feel his already hard cock harden up a bit more, as he thrust slightly upwards. I knew he was going to enjoy this as much as I was. I sank my lips about halfway down, slurping and coating his cock with my spit. His cock tasted so fucking good.

I pulled up till just the head was in my mouth; then slammed his hard cock all the way down to the base. He let out a gasp as I held my head down on his cock for about twenty seconds, loving the feeling of his entire cock filling my mouth and throat. I slowly came back up halfway, before ramming his cock down my throat again.

With my eyes watering, I started to slam his cock in and out of my mouth, from the head all the way down to the base, gagging and coughing as I furiously fucked my mouth with his now rock hard cock.
Mark then started to thrust a little as my mouth engulfed his cock, pushing his massive dick further down my throat.

After just five minutes sucking, I felt his dick stiffen and got as solid as steel. He screamed in pleasure.
And then the flood was released, I could feel his cock pulsate as he unloaded straight down my throat; so I tightened my mouth around his shaft, as to not spill a drop of that hot, thick juicy load.
It took him at least another thirty seconds to stop blowing his load into my throat. I looked up at him, his head tilted back to the ceiling, open mouthed, breathing hard. I reluctantly pulled my mouth off his cock, and swallowed that hot load of cum down my throat.
I got up off my knees and stopped the stopwatch, eight minutes and twenty seconds. I turned the display to show Mark. He said I was right.
I knew that he would be happy with that and that he would be back for another cock sucking session sooner or later. He said I was even a better cocksucker than my lovely wife…
