hanging wedgie

The jogger lets loose a string of obscenities as she tries to get free of the bush. The branches are poking her, and having her ankles tied up in her ripped jogging bottoms are not helping. She makes it to her feet. She goes to pull up her her bottoms, but they split in two. "Fuck me!" she yells.
The jogger goes to climb over the fence. You smile and manoeuvre her just enough, so she slips, the back of her panties catch on the fence post, and she falls, giving herself a massive wedgie that digs deep into her pussy and rectum. "Owwww, fuck!" she screams. She reached behind her to try and free herself but she cannot get her panties over the fence post.
The jogger is on her toes so she does not fall further, and give herself a deeper wedgie.
You hear the door to the house whose yard the fence is part of open. You look and see someone coming out to see what the commotion is.
