Not only can it. It does. If not people would regularly be walking around with gaping butt-holes, dropping poops out of their tushies like it was their job. In hopes of being too graphic, let me elaborate. Think about your poops. Go on think about 'em. Every once in awhile (if not everyday) you look to the toilet in amazement, "Holy hell that came out of me?" That's because nature built a really elastic anus. A mechanism that expands and contracts with relative ease.
And so, for those who want to engage in anal sex, the same can be said. "Holy hell that came into me?" Yes, Anal Receiver, it did so because your butt-hole went from a size 0 to a size 8. But worry not, like all great inventions: rubber bands, quality sweatshirts, pull out couches - what moments ago seemed impossibly stretched out - goes back to tight form within seconds.
Gawed I really needed to read that right now. Thanks, I think.
