My mate's cock is extremely big

Oh yes, my mate's cock is soooooooo hot big and is perfect for riding !!! but let's start at the beginning: I've known my mate for a few years now and he's always been a loyal and funny boyfriend, but a long time ago I found him so incredibly sexy. He just looks good, what else can I say! Whenever we went swimming, I would always check out his body or when we went to the cinema to watch a good horror film, I would "accidentally" touch something on his body. And when his best boyfriend confessed to me that he knew he fancied me and found me at least as sexy as I found him, we started fucking. I love riding him and I love how gentle he is at the beginning and then how hard he gets. Not much changed in our long friendship, only that we became a bit friendlier to each other. just like today! First I rode him - that's my favourite position, then he took me doggy, when that didn't give me the right kick we changed rooms and I rode him again and at the end I asked him to squirt in a glass. Several users had already expressed this wish, which is why I wanted to fulfil it. What would you have done to me if you were my best boyfriend and in this situation? Kiss Ruby
