I know we must already have innumerable threads on this. But the ejaculation in a canine breaks down into three fractions: 1) preseminal, 2) seminal, 3) post-seminal. The preseminal is the first few shots of clear, starting immediately when he begins thrusting. It flushes / cleanses the male urethra and vaginal canal of the bitch. Second or middle fraction, seminal, also short-lived, is the cloudy-white and sperm-rich fraction, generally begins soon as he stops thrusting and feels that he is tied. Post-seminal is the third and final fraction, longest-lasting and most voluminous, beginning on the heels of the seminal and lasting throughout the tie. Twelvepaws' contribution was spot-on.
I can certainly feel it in my mouth when we do oral; his squirts tickle the back of my throat or press into my tongue a little and spread salty saline flavor everywhere in my mouth, like tears but the of-joy kind (and a bit of a sore throat for an hour or so afterward, but I don't care). Cannot feel the actual liquid shots in my butt during anal, no. But I can feel the tether (behind knot) twitching if all is calm and I'm focused. And yes, when I'm in good practice, not only can I achieve my own orgasm while knotted, but I actually have to make a strong effort
not to cum until he's done. Why? Because if you cum early before him, the pleasure and riding waves of endorphins leaves you quickly, and the knot gets uncomfortable big-time. But you're still stuck! And so you're left with pain to ride out the rest of the tie. Better to keep on edging, hold your own until he is finished (completely) with his. When you get good at this, pro tip: time your release to coincide with the moment he flags and deflates his knot, releasing you in more ways than one, and the two of you collapse into a messy puddle of spent mutual lust to lick up. Promise, it'll be better than any pillow talk you've ever heard
