.." She hesitantly continued her earlier sentence. "They wanted some... Proof" She glanced up at me on the last word, seemingly hoping I understood wi...hout further explanation.I shrugged "Just tell me what the fuck you're talking about, Jenn." She pursed her lips in thought briefly. I was intrigued. I could tell her mind was battling itself."Just take this.." She finally began. Her words and movements obviously chosen carefully "and record yourself... doing it"She leaned forward, reached back. Thoughts of trying to get away from the strange dog evaporated when she caught site of the erect cock between it's legs. It had to be at least 12 inches long, as it quivered and dripped with precum.As the Great Dane mounted her Beth grabbed the large phallus and moved to her willing pussy. Beth fought a scream as the cock pushed deep into her in one quick thrust, stretching her pussy wide. The pain rapidly subsided to be replaced by pleasure, soon she was moving back and forth to meet the dog's. I walked over and stood in front of her and without saying a word lowered my zip and took out my cock which was beginning to get interested.She looked taken aback, and began to protest, “ But, but I,”, but I stepped forward an caught the back of her head and slipped my cock up against those full ruby colored lips I had noticed earlier and as she gasped pushed it into her mouth.In a moment she began bobbing on it and I let her give me a gentle blow job with her bright blue eyes staring at me all. I tensed and moaned loudly as a rush of cum flowed down my cock and burst out of my cock tip splashing deep into mums pussy. She pushed her hips hard forward and throwing her arms round me pulled me down ontop of her. My head was between her breasts as she continued to grind her hips against me I could feel her pussy tense and relax in motion with her hips until she arched her back and her pussy gripped and squeezed hard against my cock, she screamed my name, a throaty groan rose from her mouth.
