The standard price is for a 24hour usage. 
Many different type of panties are available! Just get in touch with me after the order and I will be happy to find the ones you like most with you!
I also do like to workout a lot, so if it gives you pleasure, included in the price, I will use them during one of my workouts! 
 
Other options are available example cum in panties, video of me cumming in panties, me watching you cum on panties, me watching you using my panties ecc. Contact me for a quote on these last options.
