Simply wonderful, whether teasing a sub during foreplay, using to enhance full sex, or getting yourself off with extra filling and vibration sensation, these plugs are great for anyone who likes a little back door fun, newbies to seasoned pros alike. I've been teasing myself while writing this whole review, and as soon as I finish, I'm going to go make sure I finish! ;) 10/10 recommend, happy to answer any other questions about these truly Elite trainers from Eden Fantasies.
