Part 4: Third serving
She tried to clean herself as much as she could, but on some spots she couldn't reach, there was still Jake's cum. Now time for Marco; he had something else in mind. He walked towards the stack of hay, and tapped the top, to entice the fox to come over, and she did, she jumped on it. He took the lube and grabbed her rear. She moved her tail aside to show him her pussy, but that's not what he was interested in. He applied lube to his fingers and massaged her anus. We could see her confused face, she was presenting him her female bits, her pussy that would drive crazy any male fox, and even make them battle between them for it. Yet this human wasn't interested in her pussy and went towards her anus. Besides the confusion, she wasn't trying to break free, and let Marco massage her butt hole. I was wondering what her reaction would be when he was going to go inside. He gently sank a finger inside her; amazingly she didn't mind at all. She was such a good fox. He used the same method I used previously to lube her pussy, with the syringe and the flexible tube. Once she was all lubed up and at little loser, Marco didn't dip his dick in; he called me over. We had a plan to make her orgasm, as until now she didn't seem to have one. We are going to tie her with the device we were going to use the next day to inseminate her. The particularity of that device is it had an inflatable part simulating a canine knot. I brought it over, and let her smell it, to not scare her. The device was straightforward: insert it, but not too far in, and use the pump to inflate the “knot" part, while it is inside her vulva. The vulva is the part that can accommodate the knot, not the vagina canal; the vulva and the vaginal canal are separated by a tight ring, as I've described in part 2. I've seen other young vets pushing the “knot" part too far in and inflating it. The result was a disaster… Back to our little fox; I once again positioned her on her back, lubed the device, and slowly inserted it. Once it was in place, I gently pressed the pump, to inflate the “knot". I could see her vulva getting bigger, as I was pressing the pump. I kept pumping and was impressed seeing how much her vulva inflated with the “knot". I stopped when I felt resistance on the pump. I carefully pulled on the device, to see if the knot was doing its job to keep it in her pussy. Oh man, it was not moving anywhere. She let out a yap and with her rear legs pushed against me, but this time it wasn't to break free. I was still holding the device, and her pushing back applied more pull force on her vulva. She wanted me to pull more? If a male fox knotted her, he would pull more than what I was doing now. I pulled on the device, to the point that it was lifting her full rear. Her two legs contracted, making them straight, and I saw her anus start contracting. I had some experience with female dogs, they would have their vaginal muscles contracting on the knot, to stimulate it, and make the knot last longer; they would also contract their anus at the same time. It was also indicating she was having a vaginal orgasm. That made me extremely happy, I was making her experience something she would probably never have had in her life without my help. Time to use the inseminator for its main purpose, I reached for a syringe full of semen, that I attached to the device, and injected its content into her. The syringe contained a mix of the second batch of fox cum I ordered, of dog cum, and my own. I wanted her to have strong fox cubs; I mixed the fox cum with dog and human cum, to make the fox sperm compete not only with itself but also with the other sperm. If a fox's sperm reached an ovum, it had to be strong. If dog or human sperm reached an ovum, it would just die, as they wouldn't have the same number of chromosomes. My job was done here, I let Marco hold on to the device. While holding the device and her full rear elevated, he positioned his cock on her anus and inserted himself in her. It fully went in without any force; she was taking it like a champ. Marco was so glad to be able to insert his full dick in her. He kept a hand holding the device, and her butt in the air, and used his other hand to grab one of her hips. Marco said, “Dude, I can feel the knot pressing against my dick. And her anus is contracting around my dick! I don't think I'll last very long". He thrusted in her, giving her every inch of his cock. He continued, but as he said, and sadly for him, didn't last very long. He let go of the device, and held her up against him, holding her hips. He grunted, cumming deep in her twitching ass, giving her his load, claiming her tail hole. More groans, more jets, he will not let her go until he's done. We will probably only be able to enjoy her once a year; he was enjoying every moment. After some time, he let her go; his cock popped out, and she jumped off with the device still in her.
