I suck and swallow the huge and long cock of my bestfriend on my couch.

I cannot swallow whole the cock of my bestfriend. His cock is so thick and so long. He laughed at me thinking that I am a pro but he teased me that an amateur cock sucker. He let me sit on his cock and enjoy it. He told me that i will be his slave and makes me very happy meaning I can always habe the cock of my bestfriend. I want to try something new with him.
