Full manga title: Uchi no Musume ni Te o Dasu na! - Oyako Heroine Funtousu. It's a fun, sexy manga about a mother/daughter superheroine pair. The daughter is called "Eighth Wonder". The costumes they were are inspired by Wonder Woman and Supergirl. This is Japan though, and they love to throw in their own twists!

The scene posted below shows the mother getting blasted from behind and held unconscious. It's from chapter 11.
The scanlation shipped with a really neat splash image of the two heroines bound and gagged. It was drawn by the artist Lost One Zero.
