As soon as they were alone in the house, Emily didn't waste any time. She locked the door, turned to her step-sister-in-law, and said seductively, "You looked so hot in that dress, I couldn't help but fantasize about being deep inside you." Her gaze lowered to her sister-in-law's neck, tracing the outline of her collarbone before moving downwards. "And I'm not just talking about your pussy... I need to taste that cock of yours." Without waiting for a response, Emily knelt down in front of her and slowly unzipped her pants, revealing a huge, throbbing cock growing out of her panties. She couldn't believe her eyes. "Fuck, you're packing heat," she muttered before taking the huge appendage into her mouth and starting to suck. Her warm, wet mouth engulfed the massive cock, eager to pleasure it.
