Ejaculate

I love this view. My favorite gif or video is one where the guy is ejaculating and you can see the muscles in his taint pumping out that hot sperm and you can see his hole twitching as his sphincter muscles contract. Also notice how high his balls get when he cums. Just imagine how good that feels. Makes you want to take your engorged penis out and beat off because it's making you so horny.

This is why I like gay porn so much. I can relate to all the subtleties that you are seeing, especially a nice hard cock pumping fresh hot sperm into your mouth. That always gets me horny.
