I used to bunch up my girlfriend's granny panties, and pull them *deep* into her wonderfully puffy pussy crack. Then I'd give her a nice wedgie, pull the panties deep into her butt checks also. Sometimes I'd lift her feet off the floor, I pulled so forcefully, making her groan. But then came the fun part. I'd give her a "pussy flossing", pulling the strand of well stretched underwear back and forth, forwards and backwards, while I told her how naughty she was, until she came. Then I'd put the sodden wet panties, covered in cum stains and skid marks, in my pocket, so I could enjoy their smell and wetness the rest of the day.
