" I pulled out of Aunty Sue and knelt behind my mum with my cock nudging her pussy. "Give it her!" shouted Aunty Sue. "Give her your cock. Fuck her ju...cy cunt while I watch." Looking in the mirror again, I could see my mum's face as I fucked her from behind. She was enjoying my cock and was moaning loudly each time my balls slapped against her. "Oh, Mummy," I exclaimed, "I'm going to come. My spunk is ready to come." I pulled my cock out of her pussy and without saying a word Aunty Sue grabbed. Get it over with. Tell her, "No more 'service', Jenny." And this time tell her why. All of it. And tell her you'll get help. You and her together. You'll see a counselor, you'll work this through.I knocked. There, I did it.The door opened and, there she was, beautiful, just beautiful. Her hair was all in curls. She must've had it done again. It looked... she looked amazing. She was wearing a tight white turtleneck sweater and white jeans that clung to her legs like they had been painted. A little background information about the two of us, we met at college, fell in love and have been together ever since. I was a Cheerleader at college and my husband was a track and field athlete. Until I met him I’d fooled around with most of the guys in the football team and a few other jocks at various parties or gatherings, even sleeping with a couple of the guys and on one particular drink addled evening taking two of the football team to my bed which turned out to be quite an eventful. "Come ride it, ride it hard" he groaned slapping her bare ass cheeks."Oh god yeah...oh god yeah!" cried the woman bouncing away on his cock.Then after a bit longer she stood up and pulled his big old cock out of her pussy, then she knelt on the grass and he got in behind her before slipping his cock back into her wet cunt."Give it to me, give it to me hard you old fucker" growled the woman before the old man began slamming his cock into her.I was in a trance watching this old guy fucking this.
