Liz looks at Grace " it is a fine mix I added some snake DNA though the jaw line coding was added to her pussy and I added more of a digestion system to her womb, the size modding was easy I just needed to add a bigger limit to what the gene code said to increase the cap, though it was a little hard as you can see she is well has a lot more juices then normal that is so any acid spill will not hurt or eat away at her insides  " she says as the female rat sits fully down pulling the smaller male to her womb in a blissful orgasm... " as you can see it is working wonderfully I love this line of mix, I work very hard on it "
