“So … you want to do it again?” David strolled into the kitchen, gave his mom’s butt a firm pat, and sat down. He smiled up at her pretty face. She looked tired, but radiant. And why wouldn’t she be? She’d had real sex for the first time yesterday. All yesterday.
“Rules, sweetie.” Naomi worried her bottom lip with her teeth. “I mean … we both agreed that … you would show me the one time.” She turned away from him and squeezed some oranges with a hand press. She could feel the presence of his eyes on her backside.
“Where’s Dad?” David took out his phone and scrolled through his messages. Patricia from two blocks over seemed to be getting desperate to see him again. She’d spammed him all night about how she suddenly found her husband boring and old. That she needed him. David texted her to chill. He’d see her sometime soon. But he wasn’t taking his foot off the gas with his mom. Strike while the iron’s hot. Don’t give her time to cool on him.
“He’s working, of course.” Naomi crushed the oranges. Even her arms were sore after yesterday. “He said he wanted you to do something productive today … instead of spending time with … girls.” She was glad he couldn’t see her blush as she finished with the juice.
“Is that what you think I should do?” David took the glass of juice she handed to him and tried to make eye contact, but she looked away and hid behind her brown hair.
“No … You should go see one of your girls … your women, I mean.” How many local wives and mothers had given in to her son’s magnificent penis? When she’d brought him into the world, she’d never considered that eighteen years later he’d have so many dirty talents.
“There’s only one girl I want to see today.” David’s confident smile broadened. He tilted his head a little to see if he could get her to make eye contact. It worked. She looked over at him with a combination of fear and awe.
“Which woman is that?” Naomi already knew the answer.
David took a big gulp of juice, put the glass down on the table, and wiped his mouth with the back of his hand. “You, Mom.”
“Oh, my.” Naomi put her hand to her breast, clutching her housedress. “We have to use a condom.”
~~
“Drat, this one broke, too.” Naomi’s fingers trembled as she tried to put her husband’s condoms on her son. This was the problem they had the first time they’d tried Barry’s condoms. Naomi pulled off the ruptured condom and opened another foil packet. “You sure you don’t have any more of yours left?” She carefully tried to unroll it over David’s massive penis. How had this thing come from Barry’s DNA? Maybe she had big rods on her side of the family tree.
“We used them all up yesterday.” David smiled down at her. They were in his room again. She still had on her sensible bra and panties. His hard body was completely bare for her.
“We used so many,” Naomi whispered. And even so, she had still let him put his stuff in her. Well, that wouldn’t happen again. “Shoot, this broke, too.” She removed the overtaxed condom and threw it aside. She’d clean up later. “This is the last one, it better work.” She tore the last packet open.
“Sure.” David gave her the thumbs up. He knew it wasn’t going to work. He was eager to watch her try, though. It was cute how frantic she was to both protect herself from him, and also get his dick back in her pussy. He had his hooks in her. “Any luck?”
“I think … I think … I almost got it.” Naomi worked her little fingers delicately, slowly unrolling the condom. She was going to get the hang of this. Almost there. There was a little snap. Her shoulders slumped, defeated. “It broke.”
“Oh, well.” David shrugged, scooted back on the bed, and lay on his back. “What’s your favorite position?”
“Are we …?” Naomi stood and reached behind her. She unclasped her bra. “Are we still going to do it?”
“Sure thing. You want my dick, right?” David tracked her gaze to his hard shaft standing upright. There was so much hunger in her eyes. Like she’d been starving her whole life, and she’d just discovered a banquet feast. He watched her nod her head slightly to the question and drop her bra. Her heavy boobs dropped out of confinement and wobbled on her chest. “What’s your favorite position?”
“Well …” Naomi tried to focus. “Your father and I only ever do it the one way. Like you and I did … um … yesterday.” She reached down and slowly lowered her panties, never taking her eyes off David’s pulsing penis.
“Get up here and ride me then.” David beckoned her onto his bed. “Yee-haw, cowgirl. It’s time for me to teach you something new.”
“Okay,” Naomi said in a hush. Her cheeks radiated heat. She awkwardly climbed onto the bed and straddled David’s legs. She waited for instruction, her hands on her hips, because she didn’t know where else to put them.
“When the woman’s on top, she puts it in.”
“Really?” Somehow, this made her more complicit in this very unladylike act. But she scooted forward and put her fingers around his girth. “And now?” She could see his eyes on her chest, and she stuck it out a little for him. She so wanted to please him in every way possible.
“Now, lift up your butt. Yeah, farther up. Good.” David put his hands on her wide hips to help guide her. “I’m pretty long, so you need to give me some clearance. Good. Now rub the head against your lips.”
She did as her son instructed. “Oooohhhhhhhhh.” She shuddered as that bloated head parted her lips and made a wet sound against her slickness.
“Get it nestled at your opening. Good. Lower your hips. Sweet, Mom. That’s perfect.” He could feel her pussy give as his head entered her. “I can’t believe you’re still so tight after yesterday.”
“Me … either …” Naomi felt herself spreading for him. “Oh, jeez. It’s … really … big …” A couple inches slid into her. She let her hips continue their fall. “This is the last time we’re going to do this … ugh … without … a condom.”
That was music to David’s ears. “You can go buy more condoms later today. You’re probably going to need lots of practice riding.”
“David … David … David … sweetie …” The long thing was almost all the way inside her now. Her hips gave some involuntary jerks. “It feels sooooooooo … good.”
“You should see your face right now, Mom.” David smiled up into her twisted features. He thought her even more beautiful distorted as she was with pleasure. “You going to cum?”
“Noooooooo …” She hit bottom, and the penis inside her nudged something deep in her belly. “Ooooohhhhhhhhh.”
“That’s right, you don’t cum easy, do you? Don’t worry, I’ll have you trained to cum with my dick in you on command. Would you like that?”
“Nooooooo.” Naomi’s shoulders twitched. “Oh … God …” Those words kicked something inside her into overdrive. “I’m going … to …” Naomi’s eyes rolled back in her head, her head fell backward, and a sea of pleasure washed over her. He had already trained her. “Aaaaaaahhhhhhhh.”
“No, shit?” David whacked her right boob as she came. Maybe it was the position, maybe it was what he’d said. David was already cracking the puzzle. He’d have his mom cumming and coming back for more like a junkie. “Cum for me, Mom.”
“Yeeeeeesssssss.” Her hips bucked some more, then she flung her head forward and stuck her chin to her chest, shaking. Her brown hair covered her face. As her orgasm passed, she became aware that David was rocking her hips with his hands. She could hear a squishing sound from her vagina and could feel that thing pushing at different hidden spots in her depths. She let him move her, not knowing what to do.
“You gotta say, giddy-up, horsey.” David got her into a back-and-forth grinding motion, so that her clit rubbed up against him. He wanted to get her off again. He was going to hit her pleasure centers hard. “And ride me like this.”
“Okay.” She moved her hips, but couldn’t find rhythm with David’s movements. She’d never been a good dancer, and she could tell what she was doing was awkward. She put her hands on his hard chest and dug her fingernails into his skin.
“No, you gotta say it.” David pushed her back so that she was upright and her hands went up into the air. “And you can’t lean forward while riding your stud.”
“Say … it?” Naomi waved her clumsy hands in the air, trying to get her balance. Her breasts jiggled in front of her.
“Say, giddy-up, horsey.” David laughed. She was so out of her depth. He tried to remember everything about that moment, because once he broke her in, she would lose that bumbling, awed approach to sex.
“Really?” Naomi would have thought it a silly thing to say even without David’s penis all the way up inside her. Her pleasure mounted again. Was he really going to make her orgasm again? What her hips lacked in rhythm, she made up for in determination. “Giddy-up … horsey.”
“Again.”
“Giddy-up … horsey … giddy-up horsey … ugh … giddy-up horsey …” She muttered on and on until she could no longer form the words. What had he done to her? She was now an orgasming machine. He’d broken her vagina and her brain. She rode him awkwardly for over an hour until David’s grip tightened on her hips and he erupted inside her.
As quickly as she could, she staggered out of his room before he decided to bed her again. She needed to go to the drug store before they did it again.
~~
The family planning aisle had an assortment of options. Naomi selected the biggest ones they had for David. She put them in her basket. She then paused. She would need to buy small ones to replace Barry’s destroyed condoms. The store had his brand. But … she would have to ring up with two different sizes of condoms. What would the salesperson think? She put Barry’s condoms in the basket, too. Added a bunch of other stuff she didn’t need from other aisles and headed to the front of the store.
“These are good.” The saleslady held up Barry’s condoms. “Nice and thin. My husband uses them, too. Says he can feel everything, if you know what I mean.” The saleslady winked. She was a friendly middle-aged woman.
“Oh … um … er … They’re his regular protection.” Naomi didn’t know what to say. Maybe that’s why they had all broken. Too thin. She watched the items scan, dreading the extra-extra-large condoms at the end of the pile.
“Well, these won’t fit him, miss.” The saleslady paused and held up David’s condoms. “If those others are his regular size, well, these will hang off him like a tent on a fire hydrant.” She smiled kindly. “If you’re looking for some variety, we have some flavored ones, and, well … I could just walk you over there.”
“No thanks.” Naomi’s face turned scarlet. This was worse than she imagined. “I want those.”
“Are you sure?” The saleslady dubiously scanned them and put them in a bag.
“They’re for my son,” Naomi blurted out.
The woman’s eyes went wide, and she looked at Naomi with curiosity. “Did you say they were for your son?”
Naomi didn’t know what to do. She wanted to just die on the spot. Maybe she should tell this nice lady that as she stood in the store that very moment she had her son’s sperm deep inside her, trying to find her egg. Maybe she should tell her that she didn’t want to have her son knock her up and ruin her marriage. Maybe not. “He … um … has a girlfriend now.”
“And these fit him?” The saleslady rang up the order.
“That’s … um … what he says.” Naomi tried to laugh it off as she inserted her card in the reader.
The saleslady decided it was more funny than anything else and laughed along with Naomi. “Well, I guess he gets those genes from your side of the family. Eh? You certainly are a committed mother. I’d never have bought rain jackets for my boys.”
Naomi put her head down, grabbed the bag, and raced out without even collecting her receipt. If she ever had to do that again, she’d certainly go to two different stores. But when would she have to buy condoms for Barry and David at the same time again? Never, that’s when.
~~
Naomi rushed home with the condoms, opened a foil packet as she raced upstairs, and had the new condom on David in seconds. Her clothes were strewn all around the bed and floor as she rode him. It was still awkward, but she was getting the hang of mounting her son.
“It’s time you learned how to bounce on it.” David whacked a jiggling boob to get Naomi’s attention. Her brown eyes regained some focus and looked down at him.
“Bounce?” Her tongue practically hung out of her mouth as she rubbed her pelvis on him. She’d already had two orgasms on his mighty thing. “Up … and … ugh … down?”
“It’s easy, Mom. You just slide it almost all the way out and then drop back down. It’s better for the guy. If you ever have sex with Dad again, he’ll love it.”
“Of course … I’ll have sex … with your father … again.” Naomi stopped her waggling hips and tentatively pulled up. She went up and up. She kept thinking he’d slip out, but his long thing stayed in her. Eventually, with her thighs trembling, his penis fell out of her.
“Too far.” David smiled up at her. Just like training a virgin. “Put it back in. Now you know how far to go. Good. Slide down. Right. Now back up. Good. Now down. Yes. You’re … ah … getting the hang of it. Your tight pussy feels so good.” He watched her slowly figure out the movements. “It’s like when you taught me how to ride a bike. Once you get it, you’ll never forget. Keep going.” He could tell from the way she screwed up her face that she liked this new sensation.
“Oh … jeez … it’s hitting me … right … there …”
“Are you my good mommy slut?” David put his hands behind his head and relaxed as she bounced on him. What a wonderful sight. Why did he wait so long to finally bang her?
“Yes … sweetie … whatever you want … I’m a … mommy slut … oooohhhhhhhhh.” Naomi’s hips slammed down and ground into him again. Another orgasm washed over her.
A couple hours later, there were several spent condoms laying on the bed next to them. Naomi alternated between grinding and bouncing on her son. She had really gotten the hang of it now. She looked down at his handsome face with adoration. He had brought her boring life so much joy.
“I’m … close … Mom …” David’s face went still as he readied another eruption. “I want you to take … uh … uh … the condom off.” He watched her pull him out of her and crouch next to his side. She quickly removed the prophylactic.
“Do you … want to do it … on my face?” she panted.
“Put it back … in.” He drank in her frenzied expression, so full of doubt.
“But …” She looked up at him with pleading eyes.
“Put … it in … now …” His tone left no room for argument.
Dumbly, Naomi mounted him again and slid him back inside her. “Oh,” she squeaked. She bounced just like he taught her, knowing full well this would bring about his unprotected climax. Why had she even braved the embarrassment at the drugstore if this was the end result?
“Tell me … to cum in you …” David was now so close.
Naomi shook her head.
“Tell me.”
“Cum … in … me … David.” Naomi heard his shout of pleasure and her mind went berserk. His hot seed filled her womb. That was too many times she’d taken his stuff exactly where it wasn’t supposed to go. And the last time she even had working condoms. No excuses. As she screamed out her pleasure, she knew he would wash her in his seed, inside and out. She’d have to count on luck to avoid pregnancy going forward. She really was a slut now. Naomi would give her son anything.
