There have been a lot of facial pics on my blog recently. I don't know why. I guess it's because I really enjoy making them. They excite me. The ejaculation IS the ultimate visual expression of sex.
I enjoy a blowjob as much as the next guy, and coming in her mouth is exciting, but mostly on a psychological level; what could possibly be more sexual than coming in someones mouth? What could possibly be more submissive than opening your mouth and let someone release himself?
But all said and done, when it's time to spurt, I prefer coming inside my woman, letting my seed go in her pussy.
And that's very difficult to portray visually.
