When Jackie returned home, the Dalmatian college student was shocked to see Bessie very much pregnant, and her breasts a few sizes larger, and very much so dripping milk. Marlene at least had the decency to look embarrassed.
"Sorry sis." Marlene said, "I looked away for just a minute to refill the food bowls." She looked down at the ground, waiting for Jackie to yell at her, "I didn't mean for her to get pregnant."
Jackie sighed, "Its ok." She patted her sister on the shoulder, "Humans are horny anyway, and as a miller breed, Bessie was fertile enough as it is." She looked over at Bessie, who was sitting and panting happily, gently wagging her butt, causing her milk-dripping breasts to wobble. "What did she get bred with anyway?"
Marlene sighed, "Not one of the other milkers, " she pointed to a male human, who was quite happily licking his privates, as evident by his erection, "he's a mutt. Not sure what he's mixed with though."
Jackie looked at the human, he was a physically unimpressive human, skinny, small penis, the only thing even remotely desirable in breeding him was his eyes, one blue, the other green.
