Swallow your cum/his cum

I watch a lot of porn, and see many guys cum an incredible amount. But to date I never had a guy cum in my mouth "a lot".
It seems to be a genetic thing, lol. Some guys are heavy cummers, some aren't. The first time I sucked off a heavy cummer, I lost a lot of his cum down my chin and to the floor. He told me I needed to swallow as he was cumming. The second time I sucked him off (a few days later) I got it all into my stomach.

It was awesome. I could actually feel the pool of his cum in my stomach and I understood why women like that so much, lol.
