Just then we both heard a noise and she pulled my cock out of her mouth quickly and got off her knees and down off her bed She opened the bedroom door...a crack and slipped outside just in time to intercept her three year old daughter who had woken up and was headed to her mom's room."Lets put you back to bed sweetie." Crystal said."But Mommy, I'm thirsty." I heard her daughter say. "Oh mommy, you look like my pretty doll." Her daughter said."Thank you baby." Crystal said. Crystal's attire was. She undulated her hips wildly as her anal muscles tugged frantically at my shaft. I slid rythmically in her asshole, as I grabbed her pendulous breasts, fondling them gently. "Yes!" she gasped breathlessly. "Come up my ass." Then a half minute later she cried out, "HARDER, FUCK ME HARDER!" Her pelvic movements had intensified, fanny shaking like a bowl of Jell-O while my pounding pistol kept driving in and out of her dark hole. After another thirty seconds, I had passed the point of no return.. " she says, biting her lower lip.My cock starts growing. Intrigued I ask "Why. Look at you. you can go out and get laid by anybody" I'm sick of boys. I want a big....strong...man to fill up my cunt" her hands grab my arms while she says this before moving "I know you can't resist this. That is why I am always wearing shorts. I have seen the way you look at me. I have fantasized about you fucking me like you fuck mom. I have heard you guys fucking. I would play with my wet cunt listening to you. "It's a wonder you leave home."You know me. I turned as red as a stop sign."That's my sister, Allison, and her friend Shannon," I stammered. "Would you like to meet them?" Bob tells me good things about Allison." Then she put her hand on my knee and squeezed. I got another of those odd electric sensations. This caused my blood supply to make its usual U-turn and head south, and my breath to catch in my throat."Maybe you can introduce us another time. Right now, I think they have something else.
