Plumbers butt-crack

I've come to fix a leak under your sink... this is my first job on my own so I might be a little slow.. though the boss says I do an awesome job. I'm in and out from under the sink, standing up and down, the more I'm moving the more unknowingly my pants are revealing my ass-crack more and more.. at one point I pull just my thong up, but nearly my whole ass is hanging out by the end.. no wonder you're standing around watching me so much.
