Blowing a Much Younger Guy for the 1st Time

A lot of you had asked if I would consider blowing either a much younger guy or at least a guy with a bigger dick. I discussed it with my long time friend and he left it up to me. So I went for it. This guy is 24 years old just a bit older than my own kids and he has a bigger dick. What was annoying was that he felt that he had to keep pushing my head down with both his hands. He probably watches too much porn. I know how to give a blowjob. All he did was expose my grey roots. He was very horny as was his young friend who took the photos. He only lasted about a minute or a little more and he definitely had a lot larger load than I have been used to swallowing for the last several years. He wanted me to blow his friend also but I am not into that stuff. I did agree to let him film in the nude and he made himself cum anyways. It was different feeling someone so excited in my mouth but I am not sure that I would do it again guys.
