Threesome at Grandma's

Hi readers! Something a bit different from what I usually write tonight, hehe... I'd woken up super early a few days ago and instead of getting up I just lay in bed, daydreaming and idly playing with myself, and the nucleus of this story sprang into my head. It was such degenerate porn addict nonsense that I immediately knew I had to start writing it down to share with you all. I hope you enjoy!

All characters are over 18.

CW: Incest, interracial, threesome (FFM), creampie, talk of impregnation.

I squinted in the bright Florida sun as I stepped off the dingy Greyhound bus, dragging my suitcase behind me. I wasn't looking forward to this.

Oh sure, I love my Grandma Gretchen. And she's a lot of fun to spend time with. But a whole summer living with her? I wasn't sure that would stay fun for very long. And yeah, I did kind of bring this on myself - I graduated high school with no plans to go to college, got fired from McDonalds for taking too many selfies in the bathroom, and I guess I made a few too many "jokes" about starting an OnlyFans for my mom's liking. Her solution? To pack my bag and buy me a bus ticket to Tallahassee, Florida to spend the summer living with and helping my Grandma.

"Lindsey! Over here!" I heard her yell out, breaking me out of my thoughts. I looked around, spotting Grandma, and my jaw dropped.

Grandma Gretchen has never been a bad-looking woman. And she's on the young end as far as Grandmas go, having just turned 50. I'm 18, so do some math here; Grandma dropped out of high school when she got pregnant with my mom, and mom dropped out of high school when she got pregnant with me. I'm the first woman in three generations to finish high school instead of getting knocked up - see, I was smart and used blowjobs to keep the guys happy.

But anyways, yeah, my jaw dropped because Grandma Gretchen was waiting for me in a bikini top and a pair of cut off jean shorts that, even from the front, I could tell probably showed off a lot more ass than most grandmas are comfortable with.

She hustled over to meet me and I picked up my pace as well, meeting in the middle with a warm hug.

"You ready for a fun summer with Grandma, kiddo?" she asked me, all smiles. She barely looked 50; a few smile lines around her eyes and some salt and pepper in her short, spiked up hair were the only suggestions she was over 40, even.

"I am, yeah, Grandma! It's so good to see you again!" I enthused honestly. I'd always felt close to Grandma Gretchen; not just because I'd spent a lot of time with her when I was little and mom was getting her GED, but just she and I always felt a lot alike.

It maybe helps that we kind of look a lot alike; most people who saw us probably thought we were mom and daughter instead of grandma and granddaughter. We've got the same shaped face, same hazel eyes, and pretty close to the same build; she's got a tiny bit of tummy pooch that I don't, and my boobs are smaller and perkier, but otherwise we're two slimmish brunettes with wide hips carrying around a pair of massive dump trucks.

Why yes, I do consider my ass my best feature! So nice of you to notice. I don't mind being on the itty-bitty titty committee so much since I've got an ass like I'm trying to smuggle a pair of volleyballs in my shorts. Grandma Gretchen's built like she's shoplifting a pair of pumpkins.

And as she grabbed my suitcase and turned to lead me back to her car, I got an eyeful of those pumpkins! A good 2 inches of buttcheek was hanging out the bottom of her cutoffs, as tanned as the rest of her.

She tossed my bag in the back of her bright pink Jeep and hauled herself into the driver's seat. I got in next to her.

"Wow, Grandma, what's with the outfit? Trying to land a new man?" I asked, half-teasing, half genuinely curious.

She laughed hard, leaning against the steering wheel.

"Oh, kiddo," she said, wiping her eyes. "That's a good one. This is how I dress all summer these days - an old broad like me can be forgiven for holding on to a few things from her misspent youth, right?"

"It can't be that misspent if it ultimately resulted in me, right Grandma?" I gave her a smile and she smiled right back and patted my knee.

"That's right, kiddo. You must be starving after that long bus ride. How about we go get some lunch?"

***

The first week of summer went by pretty fast; Grandma owns a small HVAC company (courtesy of a failed marriage and a great divorce lawyer), and she put me on the payroll as a part-time employee for the summer. I wasn't assigned a whole lot of work and everything I was doing was pretty mindless - scanning paperwork, emailing invoices, shit like that. Afterwards Grandma would take me out for dinner, to a movie, whatever. She also owns - or is part owner, or something like that - of the Sunrise Dunes trailer park, where she lived in an admittedly pretty nice double wide. When I asked about that, she laughed; she could own her own home, sure, but she liked the atmosphere of the park and the community she had with her neighbors.

As goofy and chill as she was off-hours, Grandma Gretchen was all business when she was in the HVAC office. I guess it was performance review season, because in the first week it seemed like every installer and tech got called into her office for 30-45 minutes at least once. Her techs were all black guys, which I didn't really think about too much; I made a little bit of small talk with most of them at one point or another that first week. Most of them were between their early 20s and early 30s, all in really good shape - which makes sense, right? There's not gonna be a lot of huge fat guys doing their work. They all also told me how Grandma Gretchen was the best boss they'd ever had and how happy they were to be working here, which made me feel good. I was glad to hear Grandma Gretchen took such good care of her employees, especially by comparison to her ex husband.

I'll be honest, the thought crossed my mind to try offering one or two of the guys a blowjob, but I didn't want them to get in trouble with my grandma. The guys were pretty hot though, and I hadn't had any action except my own fingers in a week, so I was definitely jonesing for a man. I'm not gonna lie, I definitely fantasized about a couple of them during my nightly jill-offs.

And then, a week into my summer vacation, it happened.

I woke up in the middle of the night, desperately needing to pee. My phone said it was 1:23 AM on Saturday morning. I started to get up to head to the bathroom, when I realized there were noises coming from Grandma Gretchen's bedroom. Squeaking bed springs, the grunt of a man exerting himself, slapping flesh and Grandma Gretchen's voice softly moaning.

Grandma Gretchen had a guy over and was getting railed!

I completely froze. I had to pee too bad to go back into my bedroom, and I was afraid of disturbing them if I stepped out into the hall and used the bathroom. What the fuck was I supposed to do? "How to respond to hearing your grandmother getting her guts rearranged" is not covered in health class at school!

And they just kept going at it! I have no idea how long they were fucking before I woke up, but it felt like I was standing there for an hour waiting for them to finish and they just...didn't. Finally, I didn't have a choice any more; my options were scurry to the bathroom as quietly as I could and hope the flush didn't disturb them, or piss myself right there in the doorway.

Things were quieting down, and I hoped Grandma Gretchen and her man were going to just go to sleep. I took a couple steps out of the bedroom towards the bathroom, when her bedroom door swung open, filling the hallway with light.

Standing in the doorway was Marcus, one of the HVAC techs, wearing nothing but a pair of socks and a surprised expression on his face - probably mirroring the one on mine. I realized I was standing there in a pair of pastel blue panties and a tank top that absolutely was not hiding my nipples. We kind of stared awkwardly at each other for a moment, before he muttered, "Aw shit...hi Lindsey."

I heard Grandma Gretchen behind him say, "What? Shit!" and start to get out of bed.

"I just gotta go to the bathroom," I blurted stupidly, scurrying into the bathroom hoping nobody saw how red I was.

I'd gotten a good look at Marcus' cock. Even soft it was huge, and glistening with lube and Grandma Gretchen's love honey.

I emptied my bladder, flushed, washed my hands, and slowly emerged from the bathroom. Grandma Gretchen, wearing a bathrobe (did she have anything under it? I don't know) and Marcus, wearing a pair of jeans and a white T-shirt but barefoot, sat at the dining room table, sharing a joint. Grandma Gretchen looked at me as I came out, looking embarassed and guilty.

"H-hey, kiddo," she said, handing off the joint to Marcus. "So, uhhh...this is not how I wanted this to go."

"Same here, grandma," I said shyly, standing by the door to my bedroom.

She sighed.

"Lindsey, do you mind sitting with us and talking for a minute?" She asked.

I was very aware that I was in my underwear, but I moved to sit down in the chair she offered me. She took a pull off the joint and offered it to me. I hesitated. Grandma Gretchen gave me a soft smile.

"C'mon kiddo, it's not gonna hurt you, and I figure you're an adult and most people your age are probably partaking. Go ahead and take it, I'm not gonna narc you out to your mom." She offered the joint again.

I gingerly took the joint, raised it to my lips, and took a puff.

"Soooooo...yeah. As you probably heard...Marcus and I...are fucking. I've always had a very high sex drive - just like your mother, and I imagine, just like you. Your mother mentioned you talking about starting an OnlyFans, so I'm guessing you're just as horny as she and I are. I guess, though, that I've never stopped thinking of you as 'kiddo,' and I wanted to avoid exposing you to my...adventures."

She took the joint back and puffed on it slowly before passing it to Marcus.

"I've been trying to satisfy myself with Marcus and the other techs in the office, during those, uh, 'performance reviews.' I figured you'd recognize something funny was going on sooner or later but it was a short term solution while I decided how else I could handle things. Tonight I couldn't help myself, and I called Marcus to come over after you'd fallen asleep. I'm sorry you had to hear it happening."

I took the joint from Marcus.

"Grandma," I said slowly, coughing, "I get it. So I don't want you feeling like you need to apologize - sometimes my fingers aren't enough either. Sometimes you just need a man to take care of it. Honestly, I've been getting to that point since I got here - don't tell my mom this but half my 'cheerleading practices' this year were me meeting guys in an unused classroom or even under the gym bleachers."

Grandma and Marcus both broke down laughing at that.

"You're right, Gretch, she for sure is your granddaughter," Marcus said, coughing a clutching his sides.

"You don't tell your mother I'm fucking most of my employees and I won't tell her about your cheerleading practices, kiddo," Grandma Gretchen told me.

"Deal," I said, passing the joint to her.

Finishing off what was left of the joint, Grandma Gretchen gave Marcus a sly look, a wide grin spreading across her face as she turned back towards me.

"Lindsey...when you say you've been 'getting to that point' where fingers aren't enough...what did you have in mind?" She asked me.

Maybe it was the weed talking, maybe it was just that I always felt safe with Grandma Gretchen. But I looked her in the eyes and said, "I was kinda thinking...maybe...about offering one or two of your installers...a blowjob..." I could feel my cheeks coloring under my newly-acquired tan.

She chuckled. "Yeah, you're my granddaughter for sure. Marcus, baby, weren't you telling me you felt like Lindsey was checking you out when you came into the office?"

"I sure was," Marcus said, grinning as he started rolling another joint. "Felt her eyes all over me, all greedy-like. And of course, her looking just like you, Gretch, made it a real tempting idea."

"Mmmhmmm," Grandma nodded, "And correct me if I'm wrong, but you're probably just about ready for round two, aren't ya?"

I heard the words they were saying, but the meaning wasn't filtering into my head fast enough. Round two?

"Oh, you know I'm ready Gretch." Marcus laughed. Grandma Gretchen looked at me and smiled.

"Hey Linds...I got an idea to help take care of what your fingers can't, if you're game for it. Why don't you try giving Marcus a blowjob?"

The penny dropped and my eyes went wide.

"Wh-what?" I stammered. There's no way I heard that right. The weed's got to be hitting me hard, right? Because there's no way I actually heard my grandma suggest I blow her fuck-buddy.

"Why not? Don't go spreading this around the office but Marcus here's actually my favorite cock. Big and thick, great shape, amazing stamina, and ready for more as fast as I am. I think you'd have as much fun with it as I do, sweetie. And let's be real here - if you're half the sex addict I am, you must be getting real needy after a week." Grandma got up from the table and sauntered over to the fridge to grab herself a beer, her ass cheeks wobbling under her bathrobe. Marcus stood up as well, and I could see his jeans were tented.

And me? I knew I wanted to go for it, as weirded out as I felt about my grandma encouraging me.

Grandma Gretchen popped the cap off her beer and took a sip. "Go ahead and have some fun with him - call it a belated graduation present. And if you're feeling shy, I don't have to watch...though I do want to."

I could feel the heat in my pussy. I wanted this guy, bad.

"I, uh...I don't know if just giving a blowjob is gonna be enough for me tonight," I told her shyly.

"That's fine, Linds, you get whatever you need. You have my full support," she replied.

With a grin, Marcus undid his jeans and let them fall to the floor. There wasn't any underwear underneath, and the cock that popped free was even bigger than I'd seen earlier, rapidly rising to full erection. It looked as thick as my wrist and possibly close to twice as long as any cock I'd handled before. I'd never been with a black guy before, but obviously I've watched plenty of porn, and Marcus could have stood in for any of the guys I'd ever seen on screen.

"You ready for this, Lindsey?" He asked me. Before I had a chance to ask me, he scooped me up in his arms, threw me over his shoulder like a sack of potatoes, and carried me back to Grandma's bedroom. I yelped as I left the ground, but I couldn't deny that I was insanely turned on by it too.

"I'll be right there," Grandma Gretchen called before draining her beer and putting the bottle in the sink.

Marcus put me down on the bed. I hadn't been in Grandma's bedroom in years; she had a king-size bed in the center of one wall, a vanity with a mirror and a nice, highbacked chair next to her dresser. On her nightstand was an impressive rabbit vibrator and an economy-sized bottle of lube with a pump on top.

"Get them lil titties out, girl," Marcus told me. "I wanna see what you've got compared to your grandma."

I pulled my tank top off, baring my small, perky tits, pale against my surrounding tan, my pink nipples hard.

"Damn," Marcus said, running his hands over my chest admiringly. "These are nice...bet Gretch's looked just like this at your age."

"I had already had her mother when I was her age," Grandma Gretchen said as she entered the room, loosening the belt on her bathrobe and positioning herself on the chair. "So Linds has nicer tits than I had at 18."

Grandma Gretchen was naked under her robe, and with the belt loosened it fell open, exposing her breasts; a cup-size or two bigger than mine, slightly saggy, but still really nice.

I took a deep breath, and wrapped both hands around Marcus' huge black cock. Even with both hands, the head and probably two inches of shaft still projected. Somehow it looked even bigger than it had five minutes earlier. I began to kiss and lick the head, swirling my tongue over his slit.

"Ohhhh, damn," Marcus moaned. "She knows what she's doing, Gretch..."

"Of course she does," Grandma Gretchen chuckled. "She's my granddaughter after all, and her mother was just as bad. I'm betting she's never had as big as you, though...and maybe not black, either? How about it, Linds? Any black boys in your school chasing after your big ass?"

I shook my head. "My town's whiter than white," I said. "I've watched a lot of black guys in porn, but-" I was cut off as Marcus pushed his cock back into my mouth. It felt enormous, stretching my jaw as he pushed deep into my throat. His hands were on the side of my head, holding me steady as he fed me his cock.

"Fuck, that looks good," I heard Grandma Gretchen moan. I couldn't turn to look at her.

"Feels even better," Marcus grunted. He pulled back, and I gagged and gasped for air, streamers of drool linking his cock to my lips. He tasted amazing; I could taste his sweat, and a sweetness that I think was residual lube on his cock, and a faint saltiness, different from his sweat...oh, fuck. Was I tasting Grandma's pussy on him?

Fuck it, I was too horny to care. And Marcus' cock was too good. I dove back onto his cock, eagerly trying to take as much as I could into my mouth. I was halfway to his balls and struggling to go any further. I'd never failed to take a guy to the balls before, but Marcus was so fucking big. I wasn't sure I could take him but I was trying my best.

"Fuck, Linds, you're doing great, don't stop," Grandma Gretchen said, and I glanced over at her now that Marcus wasn't holding me.

Grandma's legs were spread wide, one thrown over the arm of the chair, and she was rubbing her smooth-shaven pussy aggressively as she watched me suck this huge cock. Her pussy lips with bigger and more exposed than mine were, and her pussy was still slick from her earlier fucking. I don't know if I imagined it or not, but I thought I saw some of Marcus' cum still leaking out of her and her fingers smearing it around. Seeing her enjoying watching me did something to me. It drove me wild. I'd never felt so slutty and shameless before, and I started rubbing my own pussy through the already-damp fabric of my panties.

Seeing this, Grandma said, "Let me help you with that, sweetie," and shrugged off her robe before climbing into bed next to me. I felt her hands in the waistband of my panties, tugging them down my legs as I continued to slurp and gag on Marcus' huge black cock.

"That's right, Gretch, get in on this lil slut granddaughter of yours," he said as he claimed a double handful of my hair, taking control back and fucking my face instead of letting me fuck my face on his cock. He pushed deep into my throat, making me choke on it, holding it there for what felt like a full minute before pulling back and letting me splutter for air. I had spit running down my chin, dripping on to my chest...and I wanted more.

"That's it sweetie, just like that! I'm so proud of you," Grandma Gretchen said, as her fingers teased along my smooth slit. "I had a hard time just like that at first, but you'll be taking him to the balls before you know it."

Her fingers slid between my pussy lips, encountering how soaked I was. I couldn't believe my own grandma was fingering my pussy - this was some Jerry Springer shit! I was too horny to care though, and her touch felt amazing. I spread my legs wider for her, offering her a better angle to rub me.

As much as I was struggling to take it, Marcus' cock felt amazing in my mouth. I loved how far he stretched my jaw, and I loved the way he was fucking my face. Like I said, he was probably twice as big as the biggest cock I'd sucked before tonight - and he was making sure I felt every inch of it. Grandma, meanwhile, was being a fucking tease. She wasn't touching my clit, or sliding her fingers into me, just running them up and down between my pussy lips lightly, spreading my slickness around and driving me wild with desire for more. My clit was fucking aching for attention!
