I apologise for the belated reply, but here goes.
The series from which both these cuties come from is the EXTREMELY sexy (and more importantly, HILARIOUS) Highschool DXD
The blonde is the kind and adoable nun-turned-devil Asia Argent
The smoking hot redhead is the stern but loving big-sister and leading lady of our gang, Rias Gremory, princess of the Gremory clan of Demons.
If you do NOT take the sex-obsession of our hero seriously, you are in for a RIDE of your life.
Ration a few gigabytes in your hard-drive for it, grab popcorn and coke, and enjoy.
I was wondering, your pic at http://forums.animesuki.com/album.ph...ictureid=42938 , do you know what anime series it is from? It looks like she is using a shower to wash off suds or soap from a bath? I am hoping to watch it, and in particular am wondering what episode it is from.
