My boyfriend's friend uses a cock ring on his big black cock to pleasure me and fill me with cum

My boyfriend's friend came over to our place and I was feeling a bit bored, so I decided to spice things up a bit. I teased him with my tight ass and soon enough, he had his big black cock out and ready to go. But something was missing. That's when I spotted the cock ring in his pocket. I knew exactly what he wanted to do with it. He slipped it over his massive shaft and then he was ready to pleasure me. I let him do his thing, taking his hard cock deep into my mouth, savoring every inch of it. But that wasn't enough for him. He wanted to fill me up with his hot cum. And he did just that, leaving me completely satisfied and happy. It was a great way to spend the afternoon, and I can't wait to do it again.
