He was laying on his back and I slowly crept between his legs with my torch. There they were again. The biggest balls I've ever seen. With the torch b...eing so close I could see a lot more detail and I instantly got another boner. I carefully ran my finger over his scrotum and it was very squishy. That was when I realized the long, thick bulge running under his boxers toward his belly button. I placed my hand on top of the bulge and felt his hard pulsating cock, which was leaking precum at the. I heard Shelley cry for more as they pulled out of her gaping holes. She had become a huge-cock slut and a cum dumpster.As I slumped against the rail, I was vaguely aware of the other cucks draining their cum into the bowl as I had done.

But it was his first time and I had expected.
