It wouldn't go - she called out in pain and I stopped trying."Maybe you need something to make it slippery." Yeah, but what?" Maybe my vagina. Put it ...n there first." I dipped it in. It was still very wet in there. And tried again. It went in part way but it still hurt her. "Maybe some vaseline from the medicine cabinet," she suggested.I smeared some on me and into her opening.
