The video proves the title point very well, but it would be nice to see more of the guys than just their genitals and cum. It's difficult to relate to detached genitals without faces.
Yes, it IS a wonderful feeling! Although, as a vers guy, I slightly prefer to be the one to plunge into a guy's ass, that already has a few loads inside - it's such a great turn-on to see the cum squirt and ooze out when I drive my cock inside!
