Fina then heard Sumire say, "Stop. What are you doing?"
Fina replied back almost clinically, "Sumire, I am inserting a vaginal stimulation egg. The purpose of the egg is to force the lips of your pussy to become overly stimulated so that they swell. This swelling will make it much easier for me to do the piercings that I described to you a few minutes ago."
As Fina slowly, but firmly applied pressure to the end of the egg that contained the reception tail, which also could be utilized in withdrawing the egg, she was pleased to discover that Sumire's pussy was more than wet, it was sopping wet. Fina was able to fully insert the egg without any resistance from Sumire's pussy lips because the lotion had done its work.
