He followed Elle into her bedroom and shut the door softly behind them. He leaned back against the closed door and watched as she stood by the bed and began to undress. Facing him, she slipped her plaid pajama pants down her hips and allowed them to puddle around her ankles. She stepped out of the pajama pants and kicked them under the bed. His mother-in-law was now only wearing a baggy t-shirt that hung to her mid-thigh. He knew that she wasn't wearing any panties as he had already fingered and eaten her bare pussy on the couch downstairs. She had already cum on his face once tonight, but so far his cock hadn't gotten any attention. She beckoned for him to come to her.
"Take your shirt off," he demanded.
"You first," she replied.
"No. You're not in charge here. Off."
The dirty grin she had been wearing, faltered, but she complied. She grabbed the hem of her shirt in both hands and then in one fluid motion he pulled it over her head, and she threw it at him. He didn't make any attempt to catch it and it fell limply to the floor at his feet. He drank in the sight of his mother-in-law fully nude before him. She had her arms crossed over her amble bosom - 36 DD he knew from having rooted through her underwear drawer and examined her bras several times before. They were so big that she was having to smoosh them to get anywhere near hiding them.
He smiled a filthy, perverted smile. He couldn't wait to fuck this woman. He stripped off his clothes leaving them scattered around him in small piles until he too was completely nude. His 6'2" athletic frame was toned from regular swims at the country club. His prick stood stiff to attention, and he could feel the blood throbbing through its engorged length.
He approached her quickly and took her in his arms. She sighed as he held her close to him. His cock pressed into the warm spongy flesh of her stomach. Her hands rubbed his back. His own hands were busy too. He took her right boob into his left hand and caressed the hardened nipple, while his right hand groped and squeezed her ass. Their mouths connected in a rush of hot breath and wet tongues. He kissed her deeply. She tasted of strawberries and longing.
She broke the kiss and said, "Oh my God! I have wanted this for so long."
"Then what are you waiting for?" he replied, sticking his tongue into her throat again, their teeth knocking together.
Her left hand moved from his back and traced delicately across his taut stomach and then down to his engorged penis. He had taken care to shave his balls and trim his pubes to a neat patch of hair at the base of his cock. She took him in her hand and squeezed firmly. He tensed up at the sensation. She began to stroke him off with long slow movements. He groaned into her mouth as their tongues continued to wrestle. He moved his right hand so that he was reaching between her legs from behind to rub her sopping pussy.
She squirmed with pleasure.
"I want you, so badly," she gasped. He was happy to oblige. He pushed her backwards so that she fell onto the bed. He looked down at her and licked his lips. He took himself in his own hand and jerked himself a few times. She couldn't take her eyes off his big, hard dick.
"You want me to fuck you harder than you've ever been fucked before? While your daughter is asleep next door?" he asked with a low throaty growl.
"Yes," she said, her breath catching. He could smell the sex from her wet pussy, and it was driving him crazy with lust.
"You want this dick? Your son-in-law's prick?"
"Uh-huh," she nodded.
"You're a fucking slut, aren't you, Elle?"
"Oh God, yes!"
"You know how a slut gets fucked?"
She shook her head, no. He leaned down and rolled her over onto her stomach. He then grabbed her by the hips and pulled her towards him so that she was bent over the bed. Her ass and pussy were presented to him. His wife, Kath, never liked it when he fucked her from behind - she told him that it was too impersonal - and that added an extra layer of taboo to the fact that he was about to stick his cock in her mom.
He rubbed his cock head against Elle's hot pussy lips, teasing her. She pushed back against him trying to suck him inside her. He swatted her juicy backside with a loud crack. She squealed with pleasure.
