Alright being the voice of reason here again
If Nick had incorrectly advised her she was going to be injected in the arse with something that hurt (please all add innuendo here as required
) - then I can understand how Mrs Nick would not want to wear any of the following
Period knickers - the ones that are really comfortable, hold your swollen stomach in but are invariably stained. Any of you that have gone yuk - tough shit - that is the reality of life
Washed out knickers - these are the ones you've had for years, are now grey, unelasticated but for some obscure reason you still keep them
Character knickers - the ones your partner has bought you thinking they were hilarious and you have never worn.
No one needs to see your Little Miss Slut / Cheeky monkey knickers
Sex knickers - the ones that aren't actually meant for wearing but for taking off - see also G - strings / crotchless
Baggies - you're comfortable but ever so ugly ones
That leaves you with only a few choices left
Just don't wear any - save the hassle
