Beverly Dean hated how things were going in her life. She was finding most everything boring.
Sure, she had certain things she still enjoyed. She had a book club she went to every Wednesday night, and a thousand different shows to watch on Netflix - with twice as many being added every week. But she still felt so incredibly empty most of the time.
One day she made the mistake of telling the ladies at book club about this funk she was in. She felt like it was a good idea at the time.
Boy, was she wrong.
“Is it because you’re not getting fucked?” one of them asked. “You know, sexually speaking?”
Beverly scanned over the group of forty-year-old women, some married and some divorced, with a sense of dread. She fell into the latter category, and she was wishing she’d kept her big mouth shut.
“Uh ... well...” Beverly stammered. “S-since, uh ... Dale left, I suppose I’m ... um ... not having sex.”
Everyone shook their heads. “Oh, Beverly, no, no, no,” one of them said. “No wonder you’re in a funk. Clearly you need a fat fucking cock up your cunt.”
“Or in your ass!” one of the younger thirty-nine-year-old ladies said, and snickered.
They all nodded in agreement. “That’s obviously it,” another agreed. “After I found out Brian was having threesomes at the college he taught at, I decided to go full skank mode and fuck as many men as I could! Now it was a little tough to get the men that I wanted to rail me, but surely you of all people could have anyone of your choice!”
Beverly blushed over the idea and swallowed nervously. She hated this. She wondered what on Earth she was hoping for when she told her friends about her personal struggles.
Clearly none of them were therapists. Hell, she couldn’t imagine an actual therapist saying, “Well, I believe you need a nice hard shaft rammed up your dusty cunt - that’ll fix all your fucking problems, y’know.”
Beverly shuffled her feet nervously. She felt the coffee she had drank earlier going right through her. She really just wanted to talk about the book now. “Can we just get back to the...”
“I read recently about something called ‘poly,’” a member interrupted. “I’m not sure exactly what that is but ... I don’t know. Have you tried it, Bev? I think it’s a sex thing. My daughter’s a ... um ... poly...”
“I’m ... more a monogamous sort of person,” Beverly said.
“Well, what’s stopping you now?” one of them asked. “You’re no longer with that prick Dale. The divorce was finalized, right?”
Yes, it was tough, but Beverly got her share. She got the house in the suburbs and enough money to let her live a little for the next year or so without working. Though, she couldn’t exactly call what she was doing “living”.
She cringed thinking about how nasty her ex was during those final few months as a married couple. Beverly had met Dale in college, and besides a few flings before the age of twenty-one, she was mostly just Dale Dean’s girl.
Now, twenty years later, she’d only had sex a couple dozen times with the same man. It amused her when people learned this pathetic truth about her. Everyone and their mother assumed she was crazy. You would understand if you saw Beverly’s busty and luscious figure and bombshell good looks.
She was forty-one now, and still very much had what both men and women wanted.
Beverly tossed her lush blonde hair behind her. She was feeling self-conscious about the tight skirt she was wearing and the revealing blouse. She felt like her cleavage was on full display. “I, uh ... appreciate the input, girls,” she said. “Honestly it’s probably just post-divorce blues or something. I’ll bounce back.”
She believed she would, too. She didn’t think cock was what she needed right now. She knew cocks were all the same anyway.
When she got home, she couldn’t stop thinking about cock. She didn’t watch porn, so she thought of her ex’s cock. She shivered and felt sick. She poured herself a glass of wine.
She thought her night was going to the pits when a notification pinged on her phone. She read it and beamed. It was a reminder she had set last weekend. Her son would be coming home in three days from college for summer break so remember to buy Coke Zero, it read.
Thank God, she thought to herself. She’d be too busy with her son to be thinking about cock.
Three days later, her son’s Uber pulled up outside the house. Beverly was so excited to see him. She was in the doorway and could hardly contain her excitement as Jonah was getting his luggage out of the car.
Hell, Beverly just couldn’t stop herself! As her son began wheeling his suitcase up the driveway, she ran over and wrapped her arms around him. “There’s my baby!”
“Jesus, mom,” Jonah Dean said. He was being suffocated by his mother’s big tits. “I see you didn’t miss me much.”
She hugged him tighter. She couldn’t help it! She was about two feet taller than him but she was sure he had somehow grown a little. Eventually, she heard him gasping for air and let him go.
“Sorry, oh God,” she said. “I’ve got a lasagna cooking in the oven. I also got some of your favorite snacks and a truck load of coke zero for ya.” She took his hand and pulled him into the house.
Beverly had forgotten all about her funk now that Jonah was here. He was sipping at a can of coke zero as she drained her second glass of wine and poured another. They sat on the sofa in the living room and chatted about how life was going for the two of them.
She loved hearing about her son’s college life. He seemed to be in a good place after dad left, and that made her feel warm and good. She needed to do a bit of lying when he asked about how things were going with her. The wine helped. She was in a very good place, too.
When she asked him about any girls in his life, he blushed and shook his curly brown hair. “No, no girls, mom,” he said. “I’m gunna be rich, remember? I gotta focus. Can’t let girls get in the way.”
She tried not to pry any further with girl questions. She noticed the mention of women seemed to make him uncomfortable. They talked a bit more about other things and laughed plenty.
Soon, Jonah went off to his bedroom to unpack, and Beverly poured herself another glass of wine and checked on dinner.
She felt good. She couldn’t even remember what she was so down about. She knew it would be a different story when Jonah left, but hopefully him being here now would help her get through the rest of her days.
Maybe she’ll actually attempt dating.
She drained her glass of wine and looked at the lasagna in the oven. A few more minutes, she deduced from the color. She remembered when she used to lift Jonah up by the armpits when he was little and showed him what the right color looked like when the lasagna was ready.
“Look for the edges,” she had told him many years ago. “You see that? Make sure they’re nice and crispy brown.”
He’d repeat, mouthwatering for his sacred lasagna. “Cwiiiispy Bwooowwn.”
She knew it was the drinks making her tear up now. She weirdly wondered if he’d remember that memory. Probably not. God, what if by some wonderful chance he did remember? She knew her heart would melt if he did. She looked toward the hallway to where his room was.
She shrugged and grinned. “Why not see what he’d say?” she asked herself.
Hell, he could help her lay the table if not.
“Jonah,” she called.
She waited, but he didn’t come through. “Jonah, sweetie?”
Nothing. He must be wearing headphones, she thought. She headed for his room down the hallway and knocked on the door. “Sweetie? Hello?”
Still nothing. Yep, headphones. She opened the door. “Honey, I know this is weird but would you...”
Her heart leaped up into her throat at what she saw. Her son was doing more than just wearing headphones. He was watching a video of a couple fucking on his laptop. And he was naked, too, but the real kicker for Beverly was the large, hard cock standing up between his legs.
She felt stunned - winded, even. She didn’t know what to do. She couldn’t seem to pull her eyes away from his large member as he stroked it to the video. He was sitting in his chair and didn’t seem to notice Beverly watching him.
She was thankful for that. More thankful because she didn’t think she would have been able to leave - or look away. He was so big. She had a great view of his cock from the doorway. She felt something inside her that was strange. She knew it wasn’t a good feeling, nor a bad feeling.
She felt it coming from her pussy.
Maybe it was the wine talking, she thought to herself. She found her hand slipping in between her jeans. Her fingers moved down her pussy mound to her sensitive clit. She couldn’t stop herself from rubbing it.
She wanted to think it was the video he was watching that was turning her on like this. She could see on the screen it was an older woman and a younger man getting it on in a nice-looking living room. She knew better, though. Her son was the cause of her body tingles.
He moaned as he kept long, even strokes jerking his cock. She thought it was the hottest thing she’d ever seen. She’d never noticed it before but her son was so lean. The light from the screen made him look so trim and muscly. She assumed the light was also making his cock look big. It stuck up like a pole between his legs and appeared absolutely bloated. She could see pre-cum oozing from the tip and getting his hands sticky as he continued rubbing.
She continued rubbing, too. She felt her cunt, for the first time in a very long time, leaking. She could feel pussy juice soaking her panties as she rubbed her sensitive nub to her little boy stroking himself.
Her tits felt heavy and she slipped a hand inside her blouse and tweaked one of her nipples. It was so stiff! Then two of her fingers found their way to the opening of her cunt. She began plunging them in and out of her. She was so wet down there and it felt so good. She could feel her pussy sucking on her hot fingers.
God, she was trying to pull away but she was so close. So close to what? Cumming? She hadn’t cum in a very long time. The pressure in her stomach was building, and she could feel she was on the cusp of a big cum.
She didn’t realize she had let the door open all the way.
Her son started speeding up. His fist was pounding his cock wildly now. He moaned a silent “fuck” under his breath. Then Beverly saw it. Thick ropes of gooey cum shot out of his cock and landed on his stomach. There was so much creamy cum glazing his skinny boy abs. And that’s when Beverly nearly screamed.
Her pussy exploded. Her jeans, panties, and fingers were soaked in her hot cunt juice. She was trembling and felt like lying down. She watched as her son took up tissues from his desk. Then it hit her. The door! She shut the door as quickly as she could before he took his headphones off, and hurried into her bedroom.
She fell to the floor, feeling like she was going to throw up. But then why did she feel so good, too? She didn’t know and it scared her. Her stomach was swishing around but her cunt was vibrating. She felt so alive.
She attempted to pull herself together and forget the whole thing. She put on new panties and jeans and even changed her t-shirt to a sweater. She realized her tits were aching and heavy-seeming and her nipples were hard and sensitive.
Her head was still up in the clouds. “It was just the drinks, Bev,” she scolded herself, shaking off the high. “You don’t ever do that again. That was wrong.”
She knew it, but she felt like she was a teenager again. Like she was listening to her own mother telling her not to go out with that cute boy from school. She would do it anyway and it’d feel so fucking good kissing him. Letting him touch her. Letting Jonah touch and feel and make love to his mother.
She stopped thinking about him when she suddenly heard him calling her.
“Mom!?”
Her heart was beating like crazy in her chest. He sounded worried. “J-just a minute, sweetie.”
Oh God, he knows! she thought. He knows I was jacking off watching him jack off. I’m such a terrible mother. He’s never going to want to see his own mother ever again!
She quickly looked in the mirror and fixed herself. She looked at the prim looking whore looking back at her, and shivered. She was already thinking of prison. She wiped the thought from her brain. She knew it wasn’t that bad - at least, that’s what she was telling herself to make it seem like less of a lie.
She hurried out of her room. She braced herself for the worst and found her son in the kitchen. He looked freaked out. But it wasn’t what she thought.
“Mom, the lasagna’s fried!”
He was wearing her oven mitts. The oven door was open. She saw the charcoal-looking smoking lasagna remnants on the stove top. She couldn’t have been more relieved.
“Oh God, you scared me,” she said.
Jonah incredulously cocked his head at her. Why was she so relieved about the lasagna burning? “Mom, what about dinner?”
His look reminded her of when he was little wanting to go to McDonalds. He had no idea what she had done.
No longer worried, her thoughts seemed to clear. She clapped her hands like she had the perfect idea.
“Pizza!” she blurted. “Pizza and a movie? How’s that sound?”
He smiled. She smiled, too, but a shiver ran down her back again.
She thought everything would be fine, but it wasn’t. How could it be? Day in and day out for the past week her mind had been thinking of nothing else but her son’s cock.
She knew she was acting weird around him. That first night they had pizza they sat on the sofa and watched a movie - one she’d already seen a few times already, and she was pressed up on the other side of the sofa. She knew how she was getting anytime she was around him and would always excuse herself to go “relieve” herself.
She felt like her life was falling apart all over again. When she saw her son, all she could think about was his cock. His thick, meaty cock. Fuck, if she had that inside her. His hot load pumped inside her. She knew she’d be happy.
She tried a few times to sneak peaks at it as the week went by. If he was taking a shower, she’d partly open the door. He took hot showers and the steam would cover the glass door, but she could still see the outline of his cock. Even limp it was big. She would play with herself until he turned off the water.
Then it happened. He had taken an ice cream out of the freezer, one of those suckers with a plastic stick. When she saw the discarded stick on the coffee table, she knew she had to have it.
“Want me to throw that away?” she asked sweetly, avoiding eye contact.
“Uh, yeah,” he said. She took up the wrapper and stick and went off to the kitchen. Her cunt was desperate to taste what her little boy’s mouth was sucking on. But she didn’t get through the door. “Mom, wait.”
She stopped and slowly turned to him. She couldn’t look at him. Her heart was pounding.
“Y-yes?”
“Something’s wrong,” he said.
“W-what do you mean, dear?”
“Mom, look at me,” he said.
It took a lot, but she managed to look at her son. He looked at her, worried. It broke her heart.
“Can we talk?” he asked. “I just ... I think there’s something going on with you.”
“I’ve just been a little under the weather,” she informed him. “It’ll pass.”
She tried edging out of the room, but Jonah wasn’t having it.
“No, mom,” he said. “Sit over here.”
She was listening then. He was so forceful with his words. Her loins were flaming. She knew this wasn’t going to be good.
She reluctantly came over and sat on the sofa. She sat far away from him. He sighed and got closer. She tensed up.
“Mom, what the heck is going on with you?” he asked. “You’ve been so distant this past week. You’ve cancelled all the stuff we were going to do. It’s so unlike you. You say you’re sick but you look fine to me.”
She felt like her crush was talking to her and she wasn’t worthy. She couldn’t look him in the eye still. “But I am sick, Jonah. I ... I don’t want to be but I am...”
She tried to look him in the eyes but her eyes landed on his crotch. He was wearing gym shorts, and she could sort of make out his bulge. Fuck, she just wanted to rip them off and wrap her lips around him.
Suddenly, Jonah took his mother’s chin and made her look at him. He was shocked with how red she got looking at him. She didn’t fight it.
“Please, tell me,” he said. “Is it dad? Someone else? I don’t want you feeling like this. I won’t be able to go back to college with you acting like this.”
She knew this was probably a better time than any to tell him. What did she have to lose? Her life felt like a prison now anyway. She took his hand into her’s. She felt her body shudder. She was touching him. Touching the hand that was wrapped around and pumping his cock. The hand that has probably had his cum on it. She wanted to lick it.
Now Jonah was getting red. He saw how his mother’s breathing was getting heavier and could feel a strange heat coming off her.
“Mom?”
She looked him dead in the eye. “I ... I’ve been lonely, Jonah.”
He was shocked to hear this for some reason. “But you have that club, right?
She took a deep breath, keeping a hold of his hand. “Not that kind of lonely, Jonah,” she said. She took a risk and gently pressed his hand to her chest - just above her tits. She was wearing one of her blouses and he was touching her skin.
He gulped. “O-okay.”
“It’s not right talking to you like this but ... I’m talking ... sexually.”
Now Jonah was bright red. He couldn’t believe his busty, beautiful mother was sexually lonely. Sure, he knew she could be a prude on occasion. He thought for just a second that she needed to talk to someone else about this, but he could sense that he was the only one she wanted to talk to.
“Okay,” he nodded. “H-have you tried dating?”
“No, I ... that’s not...” God, she was getting so flustered all of a sudden! She just couldn’t bring herself to say it. She knew the longer she took the more awkward it would become. She mustered everything within her being to just say the thing.
“Jonah,” she started, then she just bit that goddamn bullet. “I want YOU, Jonah. I don’t want to fuck other men. I want you and your cock and I know that’s not morally right for your own mother to say such a thing but it’s the fucking truth so help me god!”
A shiver of intense relief ran down her back. She felt like she could have orgasmed from telling him. “I watched you that first night you were here,” she continued. “You where pumping your hard cock and I wanted you so bad. I know a mother shouldn’t want such things, it’s sick - so very fucking sick. But you made me cum so hard. I hadn’t felt that way in a long time and it felt really fucking good. That’s why I’ve been so distant, you see. I ... I’ve been thinking non-stop about you and your cock. It’s like ... it’s like ... a fixation.”
Jonah was redder than she’d ever seen him. Not to mention he was staring at her tits. She didn’t realize she had placed his hands on one of her tits while she was rambling.
Feeling good, she kept going. “You used to love sucking on mommy’s tits. Do you remember? You’d used to suck me dry.”
She took his hand which was now shaking slightly. “I want to suck you and return the favor.” She took his index and middle finger and fed them into her mouth.
Jonah was having a slight existential crisis as he felt his mother’s tongue sensually sucking on his fingers. She was staring at him as she did it. He hated how hot it was and it was making him feel funny.
He would never tell her this, but he had never been with a woman. He had wanted to for a long time and tried but he just couldn’t do it. Everything she had told him made him feel like a loser. Yet, right now, his own mother looking at him like he was the shit, made him feel cool for once in his life.
All those years of trying, and now, he might finally have sex. He knew God would throw him a caveat, though. There always had to be a fucking catch.
He licked his lips over his mother deepthroating his fingers.
“Mom,” he said.
