I've grabbed small things during my travels in between sessions when a girl mentions she needs it, but I'm not really a gift giver otherwise.

A little while back some nice bloke gave a girl I was seeing a bit a really nice clit vibrator... fuck we had a good time using it the next time we met, so on that note, nice one random guy.... But it really is a shame she probably had to get rid of it, FIFO girls really don't like anything potentially indicating they might be sex workers and have a shittonne of cash on them when they're flying.
