A ready heifer

Peter opened the door and dropped his bag with a groan. The upcoming finals were going to be absolutely brutal, especially since they'd be the last ones before college.

He glanced around, looking for the house cow, and sighed with relief as he heard her in the bathroom. He was so glad that she'd been housetrained when he got her. He frowned a moment as he could no longer remember when that was, or the circumstances behind it, then shrugged and grabbed a jug to get his after-school drink.

He'd never thought it odd that he had a pet cow in the city. Nor that her milk would be so beneficial.

He smiled to himself as he saw her bent over the sink and dropped his pants.

Maria looked up as she heard Peter's belt hit the floor, and she felt a horror that her clouding mind couldn't comprehend. Peter, her owner, was home. That was good, wasn't it?

Peter sighed as he grabbed her hips and rubbed his bare cock against her pussy. "Nothing like a nice warm hole after a rough day."

He put the jug on the counter in front of her, and she began to feel... guilty? She should have had his milk ready for him, but she also knew that he enjoyed milking her after his afternoon quickie... right?
