I was hanging out with my father-in-law at the beach, and things took a wild turn when he started to act a bit naughty. He's always been a bit of a nudist, but this was the first time I saw him get fully aroused. His excitement was directed towards me, and it was clear that he wanted to do something about it. I couldn't resist giving him a little help, and before I knew it, I was on my knees, sucking his big cock. It was quite a sight to behold, his massive member standing tall and proud. I had to admit, it was quite a thrilling experience, and I couldn't help but get a little excited myself. It's not every day you get to pleasure a man with a cock as big as his.
