I recently browsed through my extensive libraries and recovered two excellent quality and good duration expansion scenes, and everyone knows how uncommon it is for them to be featured as something of any importance in the show at all, so I hope you enjoy these. The videos require the XVID codec to play, but most media players automatically download it.
These videos do contain hentai-related content, so therefore they aren't just expansion art, especially the last part of the Bondage Game clip and the beginning of the Ma Ga Ochiru clip.
