Mind Control Sex Story: Roy has a harem...or does he?
Caution: This Mind Control Sex Story contains strong sexual content, including Ma/Fa Mind Control NonConsensual Heterosexual Interracial Black Female White Male Oriental Female First Oral Sex Pregnancy .
Roy Brody, 18 years old, checked himself out in the mirror. He’d asked the hairstylist to indulge herself and give him a new coif, and he had to admit that he looked pretty good. His previous shag of brown that hung listlessly about his ears was now shaved close on the sides and back, and the wavy top was held in place by gel. This, combined with his acne having finally faded away after years of embarrassing blotches, made him think that he might actually have a chance at getting a girlfriend.
His phone chimed. Time for work! He grabbed his backpack and headed out.
He strode down the sidewalk, noting how the day, which had started with some Spring rain, was drying out as the fresh sun beat down. He heard his phone chime again, but it sounded different from his timer.
“Roy!”
He turned to see his neighbor waving at him from her front door and headed to speak with her. The handsome woman in her late 30’s had light olive skin, dark hair tied up with a bandana, and wore capri pants that showed off her long legs, as well as a tied-up top that showcased her D-cup breasts. He spied a glistening between them, attesting to her having been working outside.
“Hey, Mrs. Maragos, what’s up?”
“How formal! Well, Mr. Brody, I was hoping you had time to help unclog my pipes?” She gave him a wink and a grin.
He felt some sweat running down the back of his neck and rubbed at it. “I don’t know much about plumbing.”
She rolled her eyes and grabbed him by the collar. “Just get in here and fuck me,” she hissed as she pulled him into her home, closing the door behind.
“What’s going on?!” he asked as the MILF pulled his backpack off and rubbed at his thin chest.
“What’s going on is I’m horny and missing your cock,” she told him and dropped to her knees to free his hardening member from his jeans.
“Holy shit...” he moaned as his 6 1/2 inches were swallowed up by her hot, talented mouth.
When he was ready, she turned, pulled down her capris and underwear, and bent over the entryway’s side table. “C’mon, I’m so ready for you...”
He just stared at the MILF’s rounded ass staring back at him. What was happening? She was acting like they’d done this before. Then he blinked ... of course they had! He remembered spying on her suntanning in her back yard a couple weeks ago, her catching him and gesturing for him to join her, and then she’d taught him how to pleasure a woman...
He reached between the MILF’s legs and felt how wet she was. He wouldn’t need any foreplay today! Smiling, he fisted his turgid member and attempted to line it up, confused that he was having trouble hitting the target. He felt Mrs. M’s hand underneath, helping to guide him inside her. “Ohh yeahh...” he moaned as his cock slipped inside her warm, welcoming pussy.
“Mmm ... you can cum inside today, you lucky boy,” she told him, “I’ve been on the pill long enough.” The first few times they’d fucked, they’d had to use a condom. Having gotten pregnant back-to-back with her daughters twenty years previous, she knew her fertile insides needed protection from Roy’s no-doubt potent, youthful sperm.
“Nice...” Roy responded as he managed to ensconce his length inside the MILF’s ripe depths and began thrusting. He had to immediately slow down, as he could already feel his load bubbling up in response to her thrilling insides. Attempting to distract himself, he reached around to unbutton her shirt so that he could grab those bobbling boobs. She quickly assisted by unfastening her bra.
“Ohh...” the matron of the Greek family moaned as her young lover’s hands squished her large breasts. They were a little sore, she noted, indicating that she was ovulating. It was a good thing that she was on the pill, she knew, or she’d probably already be pregnant from the amount of Roy’s pre-cum being smeared all over the entrance to her receptive womb.
Roy heard his phone chime again. He was late for work! “Shit! I gotta...” He gripped the older woman’s boobs tighter and started rabbiting into her, feeling his delayed orgasm bubbling back up.
“Oh! Oh fuck!” she called out as she felt her own pleasure ramping up in response. “Oh, do it! I wanna feel it!”
“Ugh...”
“Yes! Cum...”
“Ugh!”
“ ... in...”
“UGH!”
“ ... MEEE!” she screamed as she felt Roy’s hot load throb deep inside her fertile depths. “UHHGG! O-HH! OOOHH!!”
Cumming inside the undulating vagina of his next-door neighbor felt incredible, way better than using his hand! Or a condom, he figured, though he had trouble remembering exactly how that felt with her. He just knew that he would do this again and again if he could. “Ooh...” he sighed as the last of his ejaculation dribbled out inside the wanton MILF’s reproductive system before he carefully pulled out. “I’m late ... gotta go ... uh, darlin’.” Why couldn’t he remember her first name?
On unsteady legs, she gave him a cum-drunk kiss as he dressed and then saw him out the door. With a lovestruck grin, she toddled over to a chair and lay back, playing with his pearlescent semen as it slipped out of her satisfied pussy. She so loved it when her men came inside her ... she could keep a piece of them inside her all day...
She frowned. Birth control pills? She’d never used those in her life. Her husband had gotten a vasectomy after the second snap pregnancy almost two decades ago. Oh God! What had she done?!
Her phone chimed and she looked at it. She wondered, what had she been doing? Oh, right, licking up the runnels of Roy’s cum as it slipped out of her needy pussy. Yum...
Though staff weren’t supposed to have their phones on them, management didn’t seem to care if they were kept on silent. As he changed into his McUniform, Roy took a brief look at his screen, catching a glimpse of a vibrant-colored letter K logo on it before he slipped the device into his pocket. What was that? Well, he’d have to deal with it later. He quickly headed upstairs and logged into the system.
“Late, Mr. Brody?”
He turned to see his manager frowning at him. The overweight thirtysomething woman had curly, rust-colored hair and a perpetual scowl. “Sorry, Bonnie.”
“It’s getting busy ... see me after your shift.” She turned and headed back into her office.
“Ooh, you’re in trooouble...” his co-worker Kaylie taunted him as he headed to the grill, the light glinting off the thin dishwater blonde’s braces as she grinned.
The lunch rush was handled and then things died down. As per company policy, staff began cleaning. Kaylie joined him outside the washrooms, matching mop in hand.
“Hey...”
He turned to the slim blonde. “Hm?”
“You think Bonnie wants to fuck you?”
“WHAT?!”
The young woman pushed him into the men’s room and the door closed behind. She turned the lock and then kissed him hard, her braces scraping his lips. The 18-year-old had gotten them shortly after getting hired due to their small but helpful dental benefits.
“Kaylie?”
“What, I can’t be jealous? I saw how she looked at you this morning.” She rubbed at his crotch. Despite the weirdness of the situation, he was getting hard. “Well? We don’t have much time.” She unfastened her trousers and pulled them and her panties down.
Roy felt his phone get hot in his pocket. “You little slut.” He unzipped, grabbed the skinny blonde by her ass, lifted her up, and shoved her back into the door. His hard cock nosed about her wet folds.
“Ooh, you’re so forceful, Roy, taking what you want...”
He growled, then realized that he was having trouble finding the right spot for his dick again.
“C’mon ... fuck meee...” She reached down and helped. A moment later, she moaned as the head of his cock slipped inside. “Yess ... OWW!”
He stopped, half of his member inside her. “You okay?”
“Felt ... like the first time again.” Her head felt mushy ... when had that been?
“Should I stop?” His thickness had flagged a bit.
She wrapped her thin legs about him. “No, keep going. Ungh...” It was really sore!
He pulled back a bit and then thrust inside again. Kaylie was really tight ... like she said, much like the first time, when he’d taken her virginity ... at some point ... whenever that was. He carefully thrust into the slight girl, her slick depths helping to offset her tightness. Soon, he was able to get a good rhythm going.
“It’s ... feeling ... better...” she grunted as he took her.
The door rattled but was still locked.
“Sorry!” Roy yelled. “Cleaning up in here ... floor’s slick!”
“Yeah it is,” Kaylie sighed into his ear. She could feel her juices dripping out, unaware that some of it was blood. “Better hurry.” She nibbled his lobe.
“Ohh fuck...”
She could feel his cock thickening and throbbing. “I’m on the pill now ... do it inside...”
“Ohh fuuuck...”
“Oh, do it! Fucking cum in me! Uh! Uh! UHH!” She came hard, setting him off.
“GRHNNH!” Roy thrust deep, pushing the tip of his ejaculating cock right at the spasming entrance to Kaylie’s pristine womb before filling it with babymaking sperm.
“HNNG! NNG!” Kaylie grunted as her recently-devirginized depths slurped up Roy’s dangerous seed like she would a milkshake when the machine wasn’t broken.
“Geez...” Roy moaned as he let the slight girl back down onto unsteady feet, his red-tinged release already starting to burble out.
She quickly pulled up her underwear to keep it in place, followed by her slacks. “Mine now ... even if you fuck Bonnie later, I got it first.”
“You’re perverted.” He gave her a quick peck, which she turned into a tonguey, brace-filled smooch. A few moments later, she slipped out to clean the women’s washroom while he took care of the evidence.
The rest of Roy’s shift was fairly busy. During one lull, he looked over to see Kaylie at the fryer, looking worried. She pulled her phone out, blinked a couple times at the screen, and then put it away. She noticed him looking, gave him a flashy smile, and rubbed at her slim tummy. He grinned back.
After work, Kaylie gave him a pinch on his butt as she left and he wandered over to Bonnie’s office.
“Close the door,” the husky redhead directed him. “Have a seat, loverboy.”
He sat, confused.
She turned her tablet toward him to reveal the video of him fucking Kaylie in the men’s room.
“Oh.”
Bonnie sat her plush ass on her desk facing him. “Yeah ... company policy says I gotta can you both, but I figure I can maybe get something out of this instead, since my hubby’s been hands-off lately. Seems you can fuck, but are you any good at licking pussy?” She unfastened and pulled down her tight slacks and granny panties, then sat back, her thick thighs wide.
Roy gave her a lopsided grin and dove in, licking and slurping at her meaty pussy surrounded by rusty curls. She was already wet down there from watching the sex video.
“Not bad, but I expected more,” she sighed.
Roy was confused ... with all the sex he’d been having with Mrs. Maragos and Kaylie, he must have gone down on them at some point ... why was he having trouble giving Bonnie oral pleasure? Finally, frustrated, he surreptitiously pulled down his bottoms, stood up, and thrust his hard dick into his manager’s wet, wide-open pussy.
“Ohfuck!” she cried out as he quickly bottomed out. “Fuck! Oh fuck! You’re bigger than my husband!”
“Hrgh...” he growled as he rabbited into her. Ripping open her blouse, he found that she wasn’t actually fat, but her ginormous boobs just made it look that way. She was robust, with a slight roundness to her stomach from having a kid who was in kindergarten.
“Shit ... shiiit ... I’m cumming!” She arched her back as her body shook in pleasure. When she relaxed, Roy pulled out, turned her onto her front, and thrust back inside. “H-ungh!” she grunted.
He unfastened her valiant titsling and groped her massive hooters as he sawed into her cushy behind.
“Ugh ... ugh ... ugh!” she continued grunting as her employee’s cock started the tingling inside her that signaled another crushing release. Then she realized: “Wait ... we need a...” Something off to the side captured her attention ... a multi-colored K appeared on the screen of her tablet, the stylized letter pulsing. “ ... con ... dumb...?”
Roy didn’t hear her mutterings. “Hungh!” He thrust deep inside his annoying manager’s curvy body as his own orgasm blew through his loins, his load rushing up his shaft and blasting her unprotected cervix.
“Ohhhfuuucckkk!!” she screamed as pleasure exploded from where burst after burst of Roy’s hot seed penetrated the place reserved for her husband. So overwhelmed, she barely noticed when the young man finally pulled out.
“You don’t need blackmail, Bonnie ... I’ll fuck that ripe peach whenever you want. Also, cameras in the washrooms are against the law, so...” He smacked a rounded buttock, making her groan. “I’m gone ... fuck you later.”
Bonnie unsteadily flopped into her chair and looked down at the voluminous load dripping out as she calculated her cycle. She figured she’d better seduce her husband tonight, just in case.
As Roy walked home in the darkening gloom of evening, he checked his phone. That weird, multi-colored K logo was still there, and now that he had time, he could see ‘Retroactive Harem’ below that. What the hell did that mean? No, really, he had no idea what those words were so he had to ask Siri. Okay, he definitely had a harem with three fuckbuddies, but retroactive? It made no sense.
A woman jogged by, then he felt a tap on his shoulder and turned. “Huh? Oh, hey...” It was the jogger ... she was brunette, maybe thirty, wearing tight gear. While athletic, he could see some jiggle in her wiggle.
The pretty woman put one hand on her hip. “What, you lose my number?” She was holding her phone in the other hand, the multi-colored K logo flashing.
“Um...”
She gave him a grin. “I’ll forgive you if you take me behind those trees and fuck me.”
“Oh ... ohhkaaayy...” he blathered as she grabbed his hand and pulled him into the darkness of the nearby copse. Once hidden from the road, she tucked her phone into her armband, yanked her top up, and started kissing him.
It was happening again! Some random woman ... Roy blinked. No, he’d had sex with this woman several times after meeting her ... somewhere. He took her B-cup breasts in his hands, making her moan into his mouth.
She pulled back — “Gotta hurry ... c’mon...” — and yanked her jogging tights and underwear off before leaning forward against a tree. “I’m ready.”
Roy fisted his hard length and slipped it between her hot, glistening thighs. As with the women earlier that day, though, he was having trouble finding the mark. His lover reached down and helped him inside her.
“Ooohh ... that hits the spot,” she moaned as he quickly bottomed out inside her. She got so horny when she was ovulating, and the sensation of the tip of her young fuckbuddy’s member tapping at her softened cervix made her feel so good.
“Ngh ... ngh ... ngh...” Roy grunted as he took the woman from behind. Despite cumming three times already that day, his balls felt as full as ever.
“Fuck ... fuck ... fuck...” the nameless woman moaned as Roy took her. She gasped as his hands reached around and took hold of her breasts again, his fingers quickly finding her nipples, hard from the coolness of the night air. “Gnghh...” she moaned as she came.
Then they heard a couple people on the road talking as they got closer to the lovers’ hiding spot. Roy and the woman stopped moving.
“Gnh...” she gasped.
Roy felt her pussy still squeezing at his cock.
“Ngh...”
She was still cumming, the excitement of possibly getting caught at odds with the need to be quiet.
He could take no more and thrust as deep inside the woman as he could as his load exploded at the entrance to her primed uterus. “HHHHNNGGKK!”
“HNNGGHH!” She stuffed her fist into her mouth as her orgasm reboubled upon itself. Her unprotected cervix spasmed open in pleasure, allowing several bursts of Roy’s sperm-filled semen to shoot directly inside her welcoming baby chamber. “NGH! NNGGHHH!!” Her body shook in pleasure as it was possibly impregnated by a stranger.
When the last of Roy’s cum dribbled out inside her defenseless depths, she collapsed to her knees, causing his deflating member to slip out. “Ohhh...”
They paused to listen and found that the voices were moving away.
“Heh ... heh heh...” she giggled.
Roy helped her to her feet and she pulled her bottoms back up, trapping his cum inside her hot little hole.
“I, uh, think I did lose your number, if you could put it back into my phone?” he asked sheepishly as he handed her the device.
She sighed and they swapped phones, both of them dismissing the K app to get to the other’s contact list.
After getting his phone back, Roy looked at the new contact: Lyla. Of course her name was Lyla ... how had he forgotten that?
Back on her own phone, Lyla noted Roy’s name with the same sense of curiosity. “Sooo ... how have you been?” she asked, suddenly awkward.
“Good. Just got off work.”
“Burgers?”
“How’d you know?”
“You smell like cooked meat.”
“Oh ... yeah, I usually shower when I get home. Uh, anything interesting happen lately?”
She thought for a moment. “Yeah, some guy about your age bumped into me while I was jogging yesterday morning and just propositioned me, right out of the blue! Can you believe it?” She stepped out of the trees and headed back to the road.
His eyes scanned her tight body in the dim light as he followed. “Well, yeah.”
She smiled back at him. “You don’t have to be charming, y’know ... I’m already gonna fuck you whenever you want.”
“Cool ... but I’m serious ... you’re really hot.”
Lyla turned and gave him a kiss. “Thanks, Roy ... see you later.” She turned and continued her jog. As she went, she could feel her lover’s seed, jostled by her movements, slowly dripping out into her panties. The vast majority of it, though, remained inside.
She slowed and stopped. Why had she done that? She wasn’t on any sort of birth control! What the fu--?!
Her phone vibrated and she glanced at it. A moment later, she shook her head and resumed jogging home, enjoying the feel of Roy’s youthful sperm as it sloshed about in her pussy.
“Heyo!” Roy announced his return home.
“Hi Roy!”
He sighed as his former teacher Miss Kanehara came around the corner. The Japanese-American woman was wearing sweatpants and one of his dad’s t-shirts that hung loosely on her, though not so loose that he couldn’t make out the swell of her C-cups. The lady in her mid-thirties had moved in with Roy’s single father a couple weeks previous. The couple had gotten to know each other over meetings to discuss the young man’s lagging Social Studies grade the previous year.
“Hi, Miss K.”
“Rose, please,” she asked him once again.
He shrugged. “Where’s Dad?” he asked as he headed to his room.
“Grocery shopping ... we’re alone.”
He turned back to the pretty Asian woman.
She looked back at him, then smiled uncomfortably. “Is something wrong?”
He frowned ... had he expected something to happen? He checked his phone. “I guess not ... sorry.” Then he continued down the hallway.
As he lay on his bed, his phone beeped, signaling an incoming photo from Lyla, his jogging-obsessed lover. It was a photo of her happy pussy, his seed burbling forth from her puffy nether lips.
You’re still dripping out!
He sent back a wink emoji.
“YES! In me! Innn ... meee!” Mrs. Maragos cried out the next morning as she came again while Roy fucked her on her marital bed.
The young man grunted and once again filled up the curvy MILF’s wanton depths with spurt after spurt of dangerous seed. A few minutes later, he gave her a kiss as she dozed there, dressed, and then headed out of the room. After he closed the bedroom door, though, he was turned and shoved back against it, a forearm against his neck.
“Did you fuck my mom?!”
He blinked. “Hey, Rhoda.” Mrs. M’s youngest daughter had come home visiting from college. The 19-year-old brunette was a younger version of her mother, though with smaller C-cup breasts and minus the extra MILF-y curves ... same gorgeous long legs, though, he remembered.
She pressed into his neck harder. “Did ... you fuck ... my mom?”
“Yep,” he gurgled with a grin.
She backed off. “That’s so fucking hot.” She grabbed him by the lapels, directed him into her bedroom, and closed the door behind. Practically ripping his jeans and underwear off, she took his hardening dick into her mouth. “Oh my God, she tastes so good. Do me too!” Rhoda yanked her tights off, showing that she’d gone commando that morning, and lay back on her bed, a four-poster twin that Roy figured she’d probably had since she was a kid ... it even had pink covers.
He pulled the rest of his clothes off and she did likewise as she watched. Then he leapt between her legs and thrust his reinvigorated member at the teen beauty’s glistening opening. This time, though, with full visibility, he didn’t need any assistance. He thrust, his 6 1/2” length pounding like a nail into wood, inch by inch, until he could feel the slight pressure of her cervix on the tip as he bottomed out.
