Show her!

"Just watching the weather..." you reply nonchalantly as you hold the photo out to her. "Ever heard of Jenny Baird?"

"Oh yes, Jenny is a friend of my daughter Kimmie!" Debbie explained proudly, her smile faltering and her eyes bulging as she examines the proffered pic. "Oh... my God!" Words failed her as she stared at the graphic image, trying to reconcile it with the girl she thought she knew, glancing sideways as the blonde pixie on TV introducing the tri-state forecast. "What... how..."

"Do you think Kimmie likes big black cock as much as her good friend Debbie?" you ask casually, relishing the combination of horror and arousal evident on your stepmother's face as she nervously licked her lips while carefully studying the photo.

"I bet she would..." she sighed dreamily before snapping back to reality. "I don't know! John, is this you with Debbie?" She glances apprehensively at the stack of photos in your hand. "What else do you have there?"

It seems you have piqued her interest. Do you show her other pictures, or is she going to have to earn that privilege? Maybe she can help you meet Kimmie and her lovely friends in person?
