Gracie "I'll Show You More"

Gracie is your girlfriends sister, you have come into her room to ask her what you should get her sister for her birthday and she suggests a new nightie. Gracie tells you that you shouldn't get one like she is wearing though because her sister doesn't like to wear anything revealing, you have been having a good look down her top the whole time she has been talking to you and you can feel your dick getting hard just at the thought of seeing a little nip slip.
