Is it normal to wear two panty liners

Just had a very lucky raid on a ladies toilet that has a security code that I know,when I got in there the sanitary bin was heaving in goodies. After stuffing a good few into my coat I made off really happy and couldn't wait to get somewhere private to view my haul.Well three of the toilet paper parcels contained very bloody
liners but they were unusal in that two liners had been used at once she had laid one liner about a 1/4 of the way along the other making a long liner?? when I opened two other parcels they were the same so she had lost a considerable amount of blood but why use two liners? Anyhow my prize was a pair of white panties that she had shit in, on closer examnation the shit was creamy white so I think she had been fucked up the arse he had shot his load in her and she couldn't hold it and had shit her pantys, the crotch smelt of pussy as if she had cum a little too.
