PT has rank smell. Hygiene appears to be good so Mom brings her in to find out why. PT finally admits that she and her BF wanted to do something kinky so they tied some bells onto his penis before having intercourse. Bells fell off and have been in her vagina for a few weeks. Once the bells were retrieved it was no contest about where the smell was from. They had begun to rot (for lack of a better word) inside of her.
