Attached Link: DM's Feeling Sexy poses

OK I just found a pose that is actually quite similar to the one you used ... it's about half way down the page on this link ...

DM's Feeling Sexy poses ... this is a reduced image of the particular pose I'm referring to .... (but they are for V4, are you using V3?)

It does have a similar feel to what you are trying to accomplish, but the twist between the lower and upper torso doesn't seem quite as severe, and her arms are actually bearing the weight of her body in a more relaxed manner. The only mods you'd have to do to this pose are to bend her head and neck appropriately, and to rotate her right arm to go more toward the keyboard.
