This session with Katie was intense! She hates the red cow milker because it is the most powerful machine, and even though her udders are fully developed, her nipples are small and sensitive. The red cow milker always doubles her nipples in size, it is very exhausting and Katie always makes great moaning (moo) sounds when she is milked by the red cow milker. But in this session, we turned up the milking speed higher than ever before! Super high speed! It is an insane milking speed, combined with lots of power. Even though Katie is an experienced HuCow, she really had a hard time during this session, don't miss it!
