well I did it I had my first knot today (by my beagle basset hound mix) and it was so amazing it felt incredible. I get what people mean now about how the pleasure from it overpowers any of the pain cause when he first started to pull his knot in and out and it started to swell it felt like it was gonna rip me in two but it felt so good when he finally locked in my pussy and started to fill me it made me feel so good and full.I definitely will be letting him knot me again.
