Allison and Joan sat together on the sofa, mother and daughter were waiting for Allison's husband Andrew to come and entertain them. Both of them were fully dressed but were struggling to keep their hands off each other. However they had agreed to do just that for the time being.
The door to the lounge opened and Andrew entered. He was wearing a pair of black lace panties which belonged to Joan, his 60 year old mother in law.
"Very nice," Allison said.
"Certainly looks very sexy," Joan agreed, "Now what have you got to do whilst wearing Mom's things?"
"Play with myself for you," Andrew replied.
"That's right show your naughty wife and horny Mom what you like doing with my sexy undies."
Andrew's cock ached with the passion in him and he opened his legs slightly as he slowly rubbed himself through Joan's panties.
"Not too fast, rub it slower, we don't want you make stains in Mom's things," Joan said.
Andrew did as he was told, gently caressing the end of his cock with his finger tips. His wife and mother in law watched hungrily as the masturbation continued.
Joan ordered him to take off the kinickers so they could see his cock better and as he did as he was told, a naughty little thought popped into her mind.
"Pretend that you are rubbing Clive's cock for us you horny bastard."
"Mom," Allison turned in surprise," that's bad."
Clive was Joan's other son in law, married to Allison's sister Kath.
Allison was so turned on by her Mom's desire and realised where all her naughty thoughts came from.
Andrew rubbed the pre-cum that was virtually dripping from his cock into himself.
"Rub Clive's cock for your Mommy," Joan said.
Allison watched as her husband's cock twitched and seemed to extend even more and she knew he was loving the dirty talk from her Mom.
"You've got a great cock Clive, let me wank you off in front of Ally, Kath and Joany," Andrew said as he gripped himself.
Joan reached down and pulled her skirt up, to reveal her red knickers. She reached inside them and was soon finger fucking herself as she watched her son in law.
"Would you like to suck Clive's cock in front us?" Joan asked.
Andrew nodded.
"Suck him until he shoot's his load in your mouth."
Andrew was gasping now as he wanked himself faster.
"Yes I want Clive to cum over my face and then you and Al can lick it off."
Allison was watching her Mom and her husband and knew that any second she was going to orgasm on her Mom's sofa. She stood up and pulled her trousers down quickly,
"I'm going to cum Mom, please lick me."
Joan knelt in front of her daughter and opened her pussy lips up with her fingers. Allison was dripping wet and Joan buried her face into her daughter's shaven cunt.
Andrew moved closer, "Do you want to watch me wank another guy off?"
The thought of her husband with another man's cock in his hand or in his mouth sent Allison over the edge and her cum squirted into her Mom's mouth as she just gasped the word yes to her husband.
Joan gulped down her daughters warm love juice, letting it spill from her mouth over her face and drip off her chin.
Just at that point Andrew let out a low moan and Joan felt the stickiness of his spunk as he shot it over the side of her face and onto his wife's shaven mound.
Joan felt drunk with lust as she tasted her daughter's cum and her son in law's cum at the same time and even though her body ached after sex, she knew this wouldn't be a short session.
As Andrew and Allison flopped down onto the sofa, Joan stood up before them.
"I hope you don't think that is it, young man, there is plenty more for you to be doing," she said.
She started to undress and told her daughter to follow suit and both of them were soon naked. Joan's tits were large and sagged down onto her stomach and she sported a newly shaved cunt. Allison had missed out on large breasts, always complaining that he fair share had gone to her sister, but her tits were firm and her nipples very erect as she stood in front of her husband.
"Time we had our arseholes licked clean I think," Joan said.
It was something both of them loved and willingly did it to each other, but today it was Andrew's turn to be their toilet slave.
Mother and daughter knelt on the floor leaning against the sofa and Andrew got behind them.
Joan's arse was much bigger than Al's and he started there, kissing her cheeks before running his tongue the length of her crack and settling on her tight little arse bud. He pushed his tongue in tasting her.
"That's good boy, lick Mom's hairy arsehole, stick your tongue right in and clean me up."
