Sister's Panties Schedule Request
 

So the other day I had an idea for a self dare. Setting as I visit my sister over the weekend every 2 weeks I can steal a pair of panties for those weeks. My idea was to steal a pair, a specific rule to follow while wearing said pair of panties, and also what condition to return them in. All of these choices I will leave up to you. Write anything, if it's against my limits, to blatantly obvious, or impossible I'll just skip it and go to the next suggestion of that category. If there are responses to this thread I will post reports after each return.

Wear the panties the entire time you are there. Cum in them at least twice and return them used
