I also agree with most of the comments below. When he was ready to unload, I would have taken that lovely cock as deep as possible and felt it throbbing and spurting straight down my throat.
I agree with the other commenters. If I had the good fortune to be sucking that beauty, firstly- I would have taken a lot more time working him, caressing with my fingers, teasing with my tongue, edging him, keeping that cock straight up and smilin' for a good long time. When he said "I'm close", that was the perfect opportunity for the sucker to back off. I think the "suckee" might even have been hoping for it. And when I finally allowed him the bliss of release, you can bet that not a drop of that thick load would have escaped. Even if some errant drop managed to get away, I'd track it down.
