If you don't want anything mediocre, just do as I did and call Marina. She's not an average girl and she won't offer you medium-level sex. She is into some new things, she never stops in her progress. I've met her 3 times and each time she surprised me with interesting sexual ideas. She has a lot of beautiful lingerie, I enjoy women in beautiful lingerie so that was definitely a plus for me. You won't feel bored with her at all. I've never used her escort services because I don't need them, but she has decent level of English and she looks really good (physical qualities + style) so I guess she will work out well as an escort to some meetings. But personally I would recommend her for sex marathon, she's unstoppable.
