Stan rubbed himself while he watched his mom undress. "Go slow," he asked when it seemed she was just shucking her clothing. He lay back on his bed, not trying to hide the fact that he was stimulating himself, was already rock hard.
"You still get turned on by this wrinkly old body?" She gave him a pouty look and he knew she was looking for reassurance that she 'still had it.'
"Mom, er Beth, how many times do I have to tell you how sexy you are. Can't you see how you turn me on?" He moved his hand, thrust his pelvis up, accentuating the outline of his erection against the fabric of his pants. "You do this to me."
"Just once more." She hooked one finger against her lower lip and Stan had to admit, standing there in her lacy bra, her jeans undone but not off yet, she turned him on. A surge of desire ran through him and he returned to rubbing himself.
"You are gorgeous. I like that you look like a mature woman. It raises your erectionability as far as I'm concerned."
"Erectionability?" She gave him a twisted smile. "But there are lots of young girls you could have."
"Let's not do that Beth. Right now, it's you I want to have." And it was true, in more ways than she realized. Ever since they'd started having their 'sessions' because of the side effect of her anxiety medication which left her horny, he'd fought hard to keep thoughts of actually fucking his mom from creeping into his mind. They had done everything else though. Their initial, through the clothing, mutual masturbation sessions had slowly progressed to include full nudity, simulated coitis, oral stimulation, and thighing. They'd even showered together.
"Show me," she stated, staring at him as she pulled her pants down.
Stan was pleased to see her panties matched her bra. She'd taken the time to dress sexy. Another shudder passed through him as he thought about his mom lusting for him. Being the good son, he opened his belt, undid the button then pulled down his fly. He did it slow though, how he wanted her to finish undressing. Like a gourmet meal, it wasn't just about the final bite, the presentation had a lot to do with the overall enjoyment of the dinner. And Stan wanted to enjoy.
When she undid her bra strap, her breasts settled with a jiggle. Stan thought he might cum right then. He could watch his mom in the nude for hours. The swell of her breasts, her pert nipples, the small wrinkles in the side-view when she raised her arms, even the faded stretch marks, all served to course blood into his throbbing cock. He pulled down his boxers, letting it wave free. Beth gave a little gasp as though she'd never seen it before.
Stan stood, stepped beside her. Standing naked with his mom never failed to send zingers through him. He wanted to rub himself against her but resisted. She raised a hand to his chest, felt his pecs, his nipples, then down over his taught abs. "You've been working out."
"Yea, a little."
Then she encircled his cock, gave it a couple of slow strokes, squeezing the head. Stan couldn't help but move his hips in time with her caresses. For a forty-something woman, she sure knew how to raise a young man.
He turned his attention from his dick to her body that he had grown to know so well. He rubbed her back, her ass, slid two fingers into her pussy. That rewarded him with another gasp. He knew she liked that. Too, she was wet, really wet. He relished the thought that she'd gotten that way thinking about him.
He moved behind her, ran his hands over her stomach, hips, breasts, up her neck. She leaned her head down, taking the finger that had been in her pussy, into her mouth. She sucked and licked it. Stan crushed his penis against her back, working it up and down, then let it follow the crack of her bum. He continued to dry hump her ass as she arched her back, guided his hands back to her breasts. "Mmmm," she crooned. "That's so nice."
"Let's get some lube out. Get greased up a bit."
"Wonderful idea."
Stan moved to the side table, slid the drawer open and pulled out the bottle of oil. He poured a generous amount into his hand and spread it on her shoulders. She took the bottle from him, began her own application. In a few minutes, both glistened. Their hands slid over each other, kneading, massaging, exploring.
"Did I tell you this oil is edible?" Stan smiled at Beth.
"Really?" She licked her lips. "That sounds inviting." She licked his neck, brushing her chest against his. "Mmmm, tastes as good as it smells."
Stan nuzzled her ear, one hand brushing her back, buttocks. He pulled her close, gripping her butt cheeks and whispered, "What's on the menu today?"
His mom gave him an odd look. She looked sad. Then, that look was gone, replaced with a smile. "I thought," she pushed back from him, sat on the bed, pulled her feet up and spread her legs. She took one hand and rubbed her vagina lips, "we could show each other what we like the best."
Stan tucked one leg under himself as he sat on the bed, braced his back against the headboard. He squeezed his cock, gave it a gentle rub. "You mean like this?" Thinking about his mom masturbating sent surges through him. Having her watch him pleasure himself was just as exciting.
Beth lay back, turned, giving him full view of her pussy. She rubbed two fingers along the outside of the opening. She moved slow, her eyes locked on his. She moved one finger, so it rested on the top of her vagina, on her clitoris. She moved it up and down with slow flicks.
Flicking glances between her eyes and what her hands were doing, Stan wanted her to know he was watching. If being watched turned her on the way it turned him on, he wanted her to have that pleasure. Too, he wanted to learn more about how she wanted to be touched, stimulated, pleasured.
"Don't forget that I like to watch too." Beth placed a finger against her bottom lip. It made her look like a shy schoolgirl.
Stan shifted, gripped his cock and stroked it slow. On the upstroke, he squeezed the head. On the down stroke, he lifted his pelvis. His erection slid smooth despite the pressure he was applying. The lube was doing its job. It felt like it was swelling, growing larger, pulsing. He watched her massaging herself, slipping a finger into her pussy on occasion, but mostly rubbing the outside, the lips, her clitoris. After a few minutes, her breathing grew deeper, her eyes became unfocussed, her hips rocked.
Stan was familiar with this behaviour. She was approaching orgasm. What could he do to heighten it for her? He had an idea.
"Mom."
Her eyes flashed open, snapped to his.
"I'm watching you." He lowered his voice to a whisper. Spoke with a low growl. "And I'm jerking off."
Her eyes flicked to where his hand was pumping his cock. Her own hand moved faster, fingers slid in and out of her pussy. They were dripping.
"I want to watch you cum."
And then she was. Her eyes closed, her hips pistoned, her fingers clambered, slid in and out. Sweat trickled down her body, mixing with the oil. Her breasts glistened, heaved as her breathing grew deep, panted. She squeezed her legs together, trapping her hand in her crotch. It continued to work there, her pelvis rocking, but the motions eased. For the next few minutes, Stan was lost, caught up in watching his mother enjoy her orgasm.
"Whew." She smiled at him. "That was intense."
"That was fun to watch."
"Was it?" She looked at his crotch. "Seems to have diminished you."
