*****
Danny's mother came in and sat her big butt down next to him. After their intimate day they felt especially close to one another and Danny put his arm around his mother and nestled against to her full bosom. She smiled with that benevolent love a mother feels when she is rewarded for her love with love in return. So they cuddled together on that hot summer night watching a movie in a blissful mother-son bond.
They were very comfortable and peaceful together that summer night with no one to disturb them. After the movie ended they went upstairs and sat at the kitchen table for desert. Danny and his Mom simply joked and laughed about regular things while spooning their melting desert. Danny finished his first and let out a huge fart.
"Danny!" His mother said sternly. He looked at her and she made a bit of a snarl and ripped a big fart longer than his with that huge butt of hers. They both giggled. Danny pushed and made another stinky fart. His mother snarled her upper lip, grunted, and ripped another one of her own. They were laughing so hard, almost crying. Then Dianne got up and said, "Oh baby, Mommas gotta go relieve herself for a minute." She loved the feeling of her stuffed bowls, looking forward to taking a big shit. "Come here and give me a kiss honey". She walked over to her son and bent down to kiss his sweet lips. She stood up and turned around and ripped another huge fart almost in his face as she walked out.
"Oh, gross Mom! That stinks!"
Dianne rushed to the bathroom and closed the door, her sphincter barely able to hold on, and she peeled off her pants as she bent over the toilet and let out a guttural grunt as she pushed out a dribbling fart and dropped a long thick turd into the bowl. She sat there for a minute, concentrating on her big shit, and started thinking about her sons wonderful hairless balls and that space underneath it. She wanted badly to keep her face down there, run her tongue deeper between his hairless legs and rim her son's hole with her tongue. She reached down between her fat thighs and pulled apart her huge labia and ran her fingers in her pussy.
A woman of her age, Dianne was getting bigger in the ass, tits, legs, and nothing more than her huge nipples and giant, thumb-like click. Her clit resembled a small penis, with its big head and protruding shaft. She got this all wet sitting on the toilet and worked herself up real good. She held her clit in her fingers and stroked it while fanaticizing about having her sons sweet face between her big thighs and grinding her massive and wet pussy into his face. Furiously palming her pussy back and forth, she leaned back and let out a long, deep groan as she masturbated on the toilet.
