S.T.P. im guessing he is talking about the engin cleaner for cars. That should take the vagina smell out and put a nice clean engin smell right in. I dont think im to crazy about the idea becasue i LOVE eating my gf out. mmmmmmm its Vaginalicious!!
Clean your self and then go to bed with him. Im personally not a fan of eating in the shower. The water seems to wash the juice away. But maybe that was the angle we were tring to do it. In Conclusion if your spic and span he is one happy man!
