I was fucking the ass of a 13 year old girl while I watched a 15 year old girl fucking a dog."You don't wait do you Becky," I whispered in her ear."I'...e been waiting 2 years for this, and finally this afternoon mom told me we were going somewhere where I was free to fuck anyone I wanted. I don't know what you said or did to her but I've never seen her so excited and I sure am happy you did what you did." Well, I don't know what I did or said either, but I'm also very happy about the outcome. So. Then, I took it about an inch in my mouth, and swirled my tongue around his tip.He let out a soft moan and, as I looked up at him, his eyes were half closed.While not the longest cock I had seen, it was by far the widest. I'm a petite girl, and I could barely reach my hand around his girth. The contrast between my pale white hand and his dark cock was such a turn-on.God, I was so wet at that point it was incredible. I glanced down and saw my juices had already left a nice sized stain on the. But again, she didn't push my hands away, instead she leaned her body back against mine, giving into the m*****ation of her big brother.Her left ear now right beside my mouth, I whispered, "I saw you last week on the washing machine." Oh, God," she answered, maybe because of the shock of my words or maybe from the pleasure she was receiving from my hands and my teasing cock.I continued, "You looked so hot pleasuring yourself." I tugged on her ear, knowing many girls' erroneous zone was the ear. "You did!" the second answers enthusiastically."Which is great news for us," the first tells me."Horrible news for you. But great news for us!" the second excitedlytells me. "We're sort of your ... guardian angels, if you will." Of course we're not" the first informs me. "But that's the closestconcept you have to what's going on." Details friend," the second shushes the first. "I'm sure you think lifeis some wondrous ... experience or something, but to us it's rather more... unimpressive.".
