Prodding against it's balls it attempts to grab at the cow girl, the slit slapping shut as it tried to get something to pull her in with. After a minute of struggling with it, the cock's urethra begins to expand from base to tip, a sudden suction pulling on the cow girl as air rushes past her. With a quick burst of suction she's pulled right into the waiting maw, gulping her down and 'burping' the extra bit of air inside the passage with her, leaving just enough as it had for the others before her. He purred and giggled happily at the mouse girl, looking so cheerful. "Yay! Thank you lady! Mmm... could you go back to my balls? That cow lady is gonna be there soon, I wanna feel the both of ya, inside and out..." He says while wagging his tail, just smiling idly, feeling her decend further and further down into the depths of his cock.
