Later that evening Danny was lounging around on the couch watching tv, feeling a little bored. God was it good to have a mother like his around! She walked in the living room just in time for a little fun with her son.
Dianne was in her soft cotton sweatsuit which draped off her bit titties and fat butt.
"How's my baby? Are you ready to play some more?" she asked walking in.
"Yeah Mom, let's play."
She stood in front of him and turned around, offering her plump ass. Danny got on the edge of the couch and put his hands on her fat ass cheeks. Through the soft cotton material her butt seemed really squishy and unusually nice. He put his thumb on the inside of her crack and grabbed as much as he could, spreading her cheeks, but there was just too much ass for his hands. He slid down to the floor and sat between his mother's standing legs, then arched his head back and began to rub his face in between her enormous bottom.
Dianne had pulled her shirt up just over the top of her mammoth breasts. She stood there fondling her big nipples as her son worked his nose deeper in her butt crack.
Danny was rhythmically moving his face around in her soft tushy when her butt gurgled a hot stinky rush of gas that went right in his face.
"Oh honey, I've got bad gas and I have to fart a lot."
"Ooo, Mom, I love it."
She felt his mouth munch deep in her assfat trying to get at her anus. She leaned back into him, pressing on his face.
"You're so good to me, you'll put up with your Mommy's stinky farts."
She felt him squeeze her cheeks together. "Okay Mom, lets see what kind of noises we can get you to make."
"Okay, here goes."
Her fat ass burbled out a long flubbery noise. Dianne grunted again, "Huhhh!" and pushed out another burst of gas in her son's face.
Danny pulled down his mom's sweatpants just so her tear dropped lard ass spilled out over the elastic waist band. He looked and marveled at this disgustingly gigantic rear end that was his play toy. He kissed his mother's smooth naked flesh all over her round bum.
He dug his hands into her deep crack and spread her ass to see her wrinkled poop hole. He stuck out his tongue and flicked her stink hole a few times, wondering when it would go next. "Pfffff" was the sound it made as he licked it.
Dianne bent over with her hands on her knees so her son could get at her rear more easily.
"That's right. Lick Mommy's dirty little shitter. Suck my asshole baby, yes."
Danny was holding her ass apart and managed to put his lips over her crapper and tried to blow air up her butt. Feeling this Dianne pushed on her anus and dumped a nice fart directly into her son's open mouth. Danny loved the feeling of his mom's puckering butthole and hot gas in his mouth. He worked his tongue in her loosening shitter and then blew as much air as he could up her ass.
"Fill me up baby, don't stop."
Danny inhaled and put his mouth back on her anus and blew in another lungful of air. It was like he was blowing up a mattress, the way he inhaled and blew out repeatedly. Now she was really full of gas for her son.
Dianne arched her back and pushed her butt out obscenely for her ass worshipping son.
"Here it comes darling. Get ready, put your mouth on my fart hole."
