Its form and functionality are similarly titillating. The pointed, very slightly flared tip allows for easy entry without being completely smooth, and while perhaps not as visually exciting as the glans of a human, certainly gets the job done comfortably and efficiently. The size when fully erect tends to be very impressive in proportion to its owner, often being much thicker and somewhat longer than the average human penis. However, most people aren't fully aware of that, because of another handy trick the canine dick can perform.
When the action begins, it's much smaller. Very thin, and a bit shorter. Once it's in, or played with sufficiently, it inflates to its full, throbbing size, allowing for the receptive partner to adjust more comfortably. No inflatable dildo I've ever seen has such a wide range of widths as does our best friends' tackle. They usually just seem to start at "too big" and get "slightly bigger." A dog's penis is much more friendly, allowing even the novice to enjoyably accommodate something really fat and juicy.
And juicy it certainly is! One of the best things about wolf wang is the precum. There is so much! And unlike ours, which merely drools when we get close to the end, theirs begins squirting almost constantly, nearly as soon as the fun begins. The result is a satisfyingly messy taste sensation that is truly without compare. On the other end, this also serves a practical purpose, contributing greatly to the fact that a dog penis is self-lubricating, a trait I'm sure we've all wished we could share at some point.
