I sucked the last remaining cum from his cock tip, then licked his cock and knot, which was diminished but still present. There is no slowing down; there is certainly no going back. I went rigid as the tip of his cock played over my pussy lips and I involuntarily jerked as his cock slipped just inside my lips and traveled up the length before rubbing across my clit. It could have been as long as 10 hours for the next guard shift change. I felt the variety was sufficient but I was looking forward to a large steak meal, which meant a large animal. The experience was just at the point of feeling that my vaginal opening would be torn by the stretching required by the knot. And, I was. At some point my clothes were going to wear out and I had only one pair of appropriate boots, although it might be possible to wrap my feet in cloth strips and use the men’s boots in the winter for short efforts.
