Lingerie...

I bought lingerie for the first time ever for me to wear for my boyfriend on valentines day and I'm soooooo nervous. It's a black sparkly dress type lingerie with a matching g-string.

But what in the world do I do though????

Do I try to wear it under my clothes and surprise him when he undresses me later that night?

Do I have it on and be ready by the time he gets home?

Do I wait until after our date and go change and walk out in it?

Do I put it in the bag with his other gifts and let him unwrap it and then go put it on???

Do I pose somewhere????

Wtf do I do????????
