Big Knickers

You and your girlfriend have just broken up, but your friend Dolly tells you that she's not surprised. She doesn't think the two of you were suited and tells you about her ex-boyfriend who used to hate on her big knickers, so she knew they weren't meant to be. But you tell Dolly you're into big granny knickers. Dolly would love to show you the pair of big knickers she's wearing now if you'd like?...
