What do you mean?
Any PMs?
Yes to the 1st question and no to 2nd. I'll keep it on the thread instead of pm in case anyone else has anything to add.
I used to do that all the time with friendly providers. At first I'd take them back after and bring them to another place next time and it worked. But it works much better to present them as a gift so shoe box tags on whatever.
Heels and something slinky are no problem
Some girls will just take them home but others will tell you they'll keep them there for next time. You can come right out and ask her to keep them there for next time but if they were really excited about the gift that's kinda mean.
The best bet is do the gift thing. If she doesn't say she'll keep them there then tell her you'll bring another set next time for her to keep there for you. In that case your expenditure obviously doubles but if she's a great provider who acted sexy in the getup then it's worth it.
If you want to see different providers then this hobby inside a hobby can get really expensive. Like I said earlier you can try bringing them and taking them and them not being a gift but service will not be as great as it could be.
Take note I did this at standard places so it was clear they weren't going to wear them for any other customers. With fs I don't know.
Be very transparent with mama right up front. Sometimes they get suspicious if you're carrying something. If she looks at the bag offer to show it. You'll put her at ease and you can at least gauge what she thinks. Plus she might give you the girl who's most conducive to it.
