I don't have a top draw :\ I have a tiny tiny room lol so... I have a bunch of plastic mini draws with clothes in mostly, a few pine baby book shelves with stuff on it (definatly keeps a good re-order lol) and pretty much I got my monitor on top of the bookcase at the bottom of my bed and enough space there for my computer case :), can't say I've got any junk as I usually throw it out when I tidy, my room is a tip again but won't take long to tidy cos it's so small lol.
underwear, a couplea sets of handcuffs, a bunch of condoms in various sorts and flavours...A throwing knife taped under the top, same as under my desk, beside my bed, next to the door, under the sink and in the cabinet over the sink. There's also a gag, blindfold, silk ropes...a thing of icy hot lube, a jumbo pack of mints...the usual sex toy kit
my PSP, some books I want to read but never get around to them, warhammer 40k orks and paints and supplies for them, my headphones, spare battery pack for my wireless xbox 360 controller and my headphones.
my top right drawer is used as storage more than anything.
