mystery solved

after the extensive lugging around of my carry-on baggage, my shoulders are exceptionally sore. A1 offers to give me a massage, which we both know is just an excuse for him to get my clothes off. but i accept because my shoulders really are killing me.

as he slides his hands down my back he feels a rough sore spot.

him: what's this?
me: oh, yeah i noticed i have a sore there, but i don't know what from.
him: *slides my t-shirt up to inspect further* i think that's a friction sore, star

i think back to vsg's floor a few nights ago. he is right. it's carpet burn.
