Futari Ecchi (ふたりエッチ, Futari Ecchi?), also known as Manga Sutra, Step Up Love Story, or Manga Love Story, is a manga series by Katsu Aki.

Futari Ecchi is a story about a newlywed couple in their mid-twenties, both virgins when they married. The story chronicles their sexual explorations. The manga combines pornographic elements with factual and informative statistics. The title Futari Ecchi ("two person ecchi") is a play on a slang term for masturbation, hitori ecchi ("single person ecchi"). This bestselling series is most famous for being a How to Guide combined into a story. So far, forty tankōbon have been released. Two other issues are set around the sexuality of women, called "Futari Ecchi for Ladies" and there's an artbook with the title "Yura Yura". A four-episode anime OVA series was produced in 2002 and 2003.

As of June 17, 2007, the manga series has been licensed in North America by Tokyopop, with the first volume released on January 8, 2008. Also, on July 2, 2007 at Anime Expo, Media Blasters announced that they had licensed the OVA series.

In Germany, both the manga and the anime are called Manga Love Story.
