A Birthday Gang-Bang For Mom

... honey," my father said as he leaned in to take a picture. Out of the corner of my eye I saw my siblings remove their clothes and crawl onto my father's bed. Clark and Jeff began sucking their s****r's tits while Tom crawled between her legs and licked her pussy. My father removed his clothes and masturbated whenever he wasn't taking pictures. Mom suddenly stopped sucking my cock and scrambled into position above me. The expression on her face had changed so much that she looked like a different woman. I was seeing lust on my mother's face for the first time. "You almost got me there with your tongue but I like to cum with a cock in my pussy," she said. Her voice was huskier than usual. She pulled my wet cock into an upright position and slowly impaled herself on it. The others stopped playing their games to watch me get my first pussy. "That's it, Mom, see if that big cock will fit in your pussy," Polly said, her voice dripping with lust. "Shoot a load into her," she said to me. "You don't have to worry about knocking her up.

Fucking felt so good that I didn't want to stop. I managed to thrust up into her for another ten minutes, long enough to give her another orgasm. When my cock slipped out of her she rolled off to the side and called for my father. "Walter, come and get your sloppy seconds now. Faster! I need a cock in me now." As my father mounted her, I noticed that his cock, although very large, wasn't as long or thick as mine. I glanced at my b*****rs and discovered that the same was true of them. Perhaps we inherited our cocks from different sides of the f****y. They put Polly on her elbows and knees. Clark and Jeff knelt by her head to have their cocks sucked while Tom took aim on her pussy. "Oh, thank you, Tommy," she said, as Tom speared her cunt. "I really need a good fuck." I felt a little out of place with nothing to do while my f****y fucked on both sides of me.
