When after sex the woman straddles the man, then slides back and forth across his lower stomach/crotch area so the cum gets smeared around, making a slimy trail and squelching sound.
Simon kept insisting on ending with a facial so i got him back by performing the slug.

I wanted to have a quickie with my girlfriend, Laura, but she slugged me so I had to shower and was late for work.
