捕まらないで!

Marcy couldn't find her husband. He'd excused himself from the Christmas party going on downstairs a while ago. She'd checked the downstairs bathrooms. She figured he MUST be upstairs. As she walked into the bathroom, she was shocked to find him near a laundry basket. With... panties??? wrapped around his stiff dick. "What are those?" she asks, dropping to her knees on the floor beside the laundry basket. Her husband tries to hide what he's been doing, but, it's much too late for that. She caught him red-handed. With his own step-sister's panties wrapped around his cock. She's furious. But quickly thinks of very fun revenge. She wraps the panties back around his cock as she taunts him, "Since you like your own step-sister's panties SO much.. I'm going to help you use them to cum! Just like you wanted! But you better do it fast... cause I didn't lock the door."
