Derek Morgan helps out Penelope with a toy 'tupperware' party

Hi everyone,

I am looking for a story that I thought would be on ff.net but I simply can't find it anywhere. it's where Penelope is taking over a friend/cousin's job regarding what she thought was a tupperware kind of party when she finds out it is selling sex toys. Derek finds out and helps her out and offers to try out the sex toys before selling them to the house parties.

I hope it rings a bell to anyone. There is one scene where they have too much sex and they are both sore that they are walking funny and David Rossi notices this when they are called into a meeting.

Thanks in advance.

Eve
