oh yum! I have to admit to a certain amount of office supply lust on my end. Not to this extent (as of yet) but I do love browsing catalogs... This was wickedly funny and well thought out. I can totally see Ianto researching and numerating the ways he can make each item a sex toy. Really I loved all of the applications but the best parts to me were Ianto's impression of Jack stretched and straining before him *guh*
So great. And I love how willing (eager?) Ianto is to play along with Jack's bizarro kink.

AND, as I am leaving a very long comment anyway... I like your theory about Jack being a conman in the sack, trying to get everyone to up the ante as it were. But personally I think that he is too charasmatic to not be amazing in bed! Basically, I think he gives as good as he gets.

I digress. Now I'm off to mem this and check for others ^_^
