Hucows – Nikki – increasing her udder size Bondage!

Nikki came to us, she wanted to be a HuCow very bad. But her udders are very small, so we decided to try our breast training machine again. This time we figured out how to make the vacuum work properly! The key is to regulate the vacuum and release times, and set the release time quite low so the pressure will stay very high. We also hired a nurse to apply lubricant to Nikkis udders, so they get sucked into the machine even further! It is a common treatment in Asian countries, but it is very painful on a high vacuum setting. Good thing we strapped her to the bed! We are sad to say this treatment did not significantly increase her udder size, more sessions may be needed.
