This reminds me of an encounter with an older Asian man in my youth. It was the first time I swallowed an Asian man's cum. He asked how I liked it and I honestly told him I loved it. I remember how he sneered at me when I begged to meet again.
This was a beautiful video where you can actually feel the passion these two shared. The bottom tells the top to 'keep it in' which is so beautiful. But the ending is so sensual as the bottom does ass to mouth and tastes his own ass on that sexy penis that was just inside his asshole. He obediently swallows any semen left in the penis that hasn't gone inside his ass. This is what I would want to do in my first Bi sex encounter with a guy.
