Sapphire - First & Last Time

Sapphire is fed up of the party and wants to go home, someone has thrown her keys in the hot tub though and she doesn't want to get wet so she needs help getting them out. Luckily you are on hand to help her out but....... you want something in return, you have noticed she is wearing a very short dress and you want to see what panties she is wearing so you make Sapphire a deal.
