But a welcome one

The Kitchen filled with Mommy's moans and squeals of joy as her master used her.

The tit-flesh moulded between his fingers even through her simple white bra and tank top.

"f-fuck mom i've always wanted this.." he said losing himself to the boner in his pants as he gripped and groped each tit, his mother's moaning egging him on.

She put both of her hands over his, delicately pushing them in. Making him grope her harder as she smiled into his eyes.
"Master you make Mommy so happy, Mommy can't believe she didn't know she was your sex **** sooner!" She said between cute little whimpers of joy.

Something clicked in Max's horny brain "mom" he stopped groping for a moment, she lowered her hands in obedience "haven't you been my sex **** forever?" he wondered how his words might have worked.

She looked puzzled at him for a moment, the warm look in her eye never fading. "No, Mommy started being your sex **** about 10 minutes ago master... Mommy would have never let you do that before..." she looked down at her son's hands firmly around her breasts, before smiling
"Mommy was so stupid before Master!"
She wanted nothing more than to offer her mouth, her pussy her everything... but she knew better than to interrupt her master's thinking.
he dropped his hands completely and put one on his chin as he thought for a moment.
Mommy made the most of the opportunity. Peeling off her sweaty tank-top... her big tits made little slapping noises as they fell down again. Still contained in their simple white bra.
Her brain now re-jigged for sex she gazed down at her own tits "These are almost the size of Mommy's head.... they were built for hot sex with Master! Why did Mommy put them in such a boring bra... doesnt Mommy want to get fucked?" she thought over and over as she stared at her perfect tits.
Her gaze lingers then on her lower form. Pushing the jeans down quickly, she hated these stuffy clothes! they'd only slow her down!

The wetness in her simple white panties was evident, they had gone see-through because of her beloved Master.
She saw her own thick thighs and sighed again, looking behind and down to her ass. she was so furious with herself. Her ass jutted out like it wanted to be touched. The plump cheeks were made to wiggle and part for her Master's big fat.... she got even wetter.
"Mommy is a perfect sex ****.... Master is so smart.... Mommy is a fool.... wearing such drab and boring underwear...." she began to tear up.

Max finally turned around, eager to ask a question. The sight of his modest mother, in her underwear. her perfect figure laid almost completely bare for him... and he didn't even ask... well lets just say the tent in his pants didn't get any smaller.
But it was the wetness of her eyes which made him stop for a moment.
"NO no mom come here!" he hugged her, pressing her nearly naked body into his own. her head was only up to his shoulders. he looked down and saw her ass. she moved it from side to side in a little wiggle, subconsciously.
Any guilt that might have been in his heart at that moment vanished, he reached down as she sobbed into his chest and groped her plump peach of an ass.
Reaching into her underwear to get a real handful... the supple flesh yielded and kneaded eagerly in his hand.

she spoke through sobbing and moaning "Mommy is sorry master! she should be wearing a thong and a little lacey bra.. like those sexy girls... you can hardly feel up Mommy's ass!" she wailed, and his boner poked her in the stomach.
The wailing stopped and she licked her lips.
"c-can Mommy make it up to her wonderful and merciful Master?"

(guess that question Max had will have to wait. sorry to not go straight into sex but i like the idea of exploring a sex slaves change in mental state a little. open to comments and critics. thank you for reading.)
