What can i do if what makes me horny is my friend's cock and not my girlfriend's ass?

Video provided by richard.xxxi'm meeting a good friend of mine to tell him about the problems i'm having with my girlfriend. he is a married man and one of my best friends and he knows that he will understand me well. i explain how hard it is for me to get hard when i'm with my girlfriend. when i ask him if he thinks i have a problem he laughs and he tells me that he knows how to fix it. he suddenly pulls out his dick and starts jerking off in front of me. it's amazing how hard i get just seeing him and how crazy i get when i start sucking him off.
