The Zoologists/Dog walked out
The dog walks over to Lisa and sniffs her. A tongue comes out and licks her face, producing a giggle from Lisa. He sniffs around her and stops at her ass. He continues to sniff and then starts licking Lisa's legs, nipping the clothing and pulling it down.
"No" Lisa quickly grabs her shorts. The dog growls and nips at her legs. Causing pain to Lisa till she moves her hands. The dog keeps going till both her panties and shorts pulled down, exposing her ass and pussy. A tongue goes from her leg, to her pussy and up past the ass. Lubricating the holes. The dog continues to lick causing Lisa to start giggling.
Then it stops. Lisa was liking that and was a bit sad that it stopped. Once that thought was processed, the dog mounted her. She didn't realise the size of the dog until it mounted her. The dogs head was resting beside hers. Hearing the dog huffing.
Then the movement started, she felt the dogs dick slam against her virgin pussy. Just missing the opening, or the hole was to small. Lisa tried crawling away but was restricted with the leach. She tried to lay down flat but the dog nipped at her neck. Forcing her to stay in position. He tried again. Miss. A third time, and six inches of his cock got buried in Lisa in one go, taking her virginity.
Lisa screamed at this. The feeling of being split in half by the dog was to much, then the dog started moving humping away at her hole inserting more of his nine inches into her. Making her feel like nothing more than a common bitch. This lasted five minutes before she felt something the size of a baseball try to enter. She knows it's his knot, he is about to breed her.
The knot slams into her a few times before a powerful thrust gets it lodged in her. The pressure made Lisa orgasm, her whole body twitched. But with the knot in, her juice's went nowhere. The dog thrusted against her and the rest of the knot went in, just as the dog started to cum. Fulling up Lisa, who was now on her elbows for support. Panting from the orgasm.
After about five minutes of being knotted, the dog started to deflate. He tries to move to early, trying to pull his cock out of the bitch causing Lisa to cry out in pain. The dog kept trying until about two minutes later and he pulls free. Mostly dog cum comes out mixed with a bit of blood and Lisa's own juice's.
The dog licks himself clean and then moves onto Lisa to clean up his mess. The cum soaked Lisa's panties and legs. The dog cleaned her up as she lay there.
