Luke's Big Butt Changes Ch. 08

With every thrust I felt Luke's soft jiggly cheeks bounce on my dick. We fucked like machinery. I pounded into him and every thrust got the reaction of a moan. The harder I fucked, the more Luke's ass shook, which just made me fuck him even harder.

I grabbed Luke's taut waist to steady himself so I could really piledrive my cock into him. Leaning against the edge of the bed, I used it as leverage so I could change the angle. When I drove my cock into Luke's wet pussy from above with a loud squelch, he yelped and his whole body shook.

I had never felt a pussy like this before. It was warm, wet, tight, soft, and elastic. His slicked up ring somehow gripped my cock with just the right amount of pressure; enough to require effort to push it in and out, but not so tight that I couldn't force my cock down smoothly. Feeling his pussy stretch and contract as I pumped into him was pushing me over the edge. Luke's pussy was perfection, like a cock-milking machine. Who knew Luke had something like this? Did Sammy know about it? If I were him, I might not be able to stop myself from using Luke's pussy whenever possible.

I felt the telltale signs of my balls going tight and tried to slow my thrusts so I wouldn't cum too soon. Luke hadn't squirted yet like he did in the office, and I knew he needed to get fucked until he did. But, Luke had a different plan. I tried to pull away, but Luke just pushed his fat ass back onto my dick and grinded his bubble cheeks onto me. I couldn't help but give his bubble butt a quick swat, which made them jiggle and ripple like jello. I gripped his cheeks hard, my fingers driven into his flesh, trying to hold perch but his ass was just too big to palm. It seemed like each cheek was bigger than a basketball, squishy yet firm, the perfect mix of powerful muscle and bouncy fat.

"FUCK! LUKE!" I tried to push him off me, but Luke was stronger. Not sure if it was because he was younger, or because I was growing weak from this intense fuck, but when Luke slammed his ass back onto me and I saw his cakes bounce forward and back, I lost it. I cried out and leaned forward as I felt my balls empty their contents into Luke's pussy.

"AW FUCK YEAH COACH, BREED THAT PUSSY!"

With every volley of hot cum I shot inside Luke's pussy, I felt waves of pleasure trail up and down my body. My balls were emptying at an incredible rate, pumping more cum into Luke than I even thought possible. It was easily the size of at least two of my regular loads, maybe even three. I collapsed onto Luke's broad back, spent from having my soul sucked out of me through Luke's perfect pussy.

"Aw fuck Coach, that's it?"

That's it?

What the fuck was Luke talking about? I pulled out of him with a wet plop, not surprised to see a large glob of pussy juice drip out of him, but not a single drop of cum. I didn't even know where it all went. Did it just get absorbed inside Luke? Even after the rough fucking I had just given Luke's pussy with my cock, the tight pink ring seemed to snap back into place easily, returning to it's previous almost virgin-like tightness. Despite it being so tight, it was rhythmically open and closing, almost yawning or like...a baby bird begging to be fed. It was clearly happy to be fed some cum - but it wanted even more, suddenly empty and practically begging for me to pound it again and dump another load inside.

"You want more, Luke?" I couldn't hide the disbelief in my voice. I flipped over onto my back so I was beside Luke, and he did the same. We looked each other in the eyes. Luke seemed better, calmed, but he was still shivering slightly, like he had all this pent up energy and frustration that he needed to get out of him.

"Coach... I haven't squirted yet." Luke said simply, his tone a little pleading.

Despite having just emptied my balls into Luke, my still semi-hard cock throbbed and began to grow back to life. Jesus, I haven't had a marathon fuck like this is a decade. What was going on?

8 Years Ago

"Luke? What are you still doing here?" I was on my way to my car in the parking lot. I always waited until the last kid was gone before leaving, just to make sure nobody was left behind. I knew that Maria would typically pick Luke up after practice, but for some reason Luke was still sitting on the curb and fiddling with his jacket.

He looked up at me and shrugged. "I'm waiting for my mom."

I knelt down to him so we were closer to eye level. "When is she going to get here? It's almost dark."

"Uhm... she said she had to stay late at work, so she'd get out at 8?"

My jaw dropped. Now, I thought Maria was a wonderful woman, and I personally knew how hard it was to be a working single parent. But asking her 10 year old son to wait in the dark for her? I couldn't stand by and do nothing.

"Luke, let me call your mom, how about you come eat dinner with me tonight?"

I was relieved when Maria said yes, and I helped Luke up into my truck before driving off. After picking the girls up from their after-school sitter, I drove home so I could get started on dinner.

"Alright, how about you three get started on homework while I make dinner?" I said, grabbing an apron to start something quick and simple like spaghetti and meatballs with jarred sauce and frozen meatballs.

My youngest, Riley, came trudging over and rolled her eyes at me. "Daddy, I'm five, I don't have homework!" I swear, this girl. She has so much sass for a five year old!

"Okay, that's fine. Why don't you play near Chrissy and Luke? You know the rule, nobody in the kitchen while Daddy is cooking, right?"

"Fiiiiiine." She moans and stomps away.

It didn't take long to finish cooking, and when I stepped out to tell the kids it's ready, I was surprised to see Luke on the floor with Riley while she introduced her collection of dolls to him. Despite being 5 years older than her and a boy, Luke didn't seem to mind it and was paying close attention to everything she said.

Chrissy decides to interrupt by poking Luke in the side a few times. "Ew, you're so stinky! Why are you so stinky, are all boys this stinky?"

"Shut up! I'm not stinky!!" Luke didn't shower after the game, so he was still a little sweaty.

"Yeah you are, stinky-boy!" Chrissy punctuated her taunting by tickling Luke's side, and before I could step in they were both laughing and rolling around on the floor.

A strange thought entered my head. Chrissy is only 2 years younger than Luke. What if they ended up together? Just the idea of Luke, as my son-in-law... it felt right.

But I knew that that was jumping the gun a little bit.

Luke flipped over, still in a daze, his face clouded by lust and need. Without saying a word, Luke reached behind his knees and drew his legs up, giving the perfect view of his still slightly gaped pussy. Within seconds, I was rock hard, my dick throbbing in anticipation of feeling that warm pussy around it again. I got up on the bed over Luke, face to face with him

.

Slick with pussy juice and remnants of my cum, I sunk my cock into Luke's pussy like butter. A sticky yet slick mixture of my remaining cum and his pussy juice helped my cock slide in, his tight little ring stretching easily to accommodate my size. The sloppiness of his hole just made the wet squelching of cock going into pussy even louder. I couldn't believe how hot this was, the fact that Luke's hole was such a mess, so wet, somehow even warmer.

As I sunk inch by inch once again, I could see Luke's face go slack as I snaked into his guts. Finally, when I pressed my pubes up against his taint, his eyes rolled back and he was completely blissed out. For the first time all day, Luke actually looked like he was calm and satisfied. It was such a relief to see that he wasn't this desperate, needy mess, almost like a junkie in search of his fix. I'm glad that it was me, someone who has Luke's best interests at heart, to help him like this. I felt an immense sense of pride, strangely, as both a sexual partner and coach.

"Fuckkkk... Coach. Fucking do it."

Looking into his face, his lust-filled gaze, his hunger for my cock, I realized something. Luke wasn't the boy I knew, the one who looked so sad as he obediently waited for his mom to pick him up. He was a man. But not just a man. A man with a pussy. A man who acted like a whore, a slut, to get what he wanted: cock.

I pumped my hips into Luke, my thighs slapping against his hamstrings. Every time I bottomed out, I ground my hips in a circular motion to stretch his pussy out. Luke seemed to really like that, because every time I did it he threw his head back and moaned.

"Coach... Coach..."

I loved seeing him like this. An expression I'd never seen on him before. Losing himself completely to lustful hunger. I angled my hips to try and find that spot again. Wordlessly, Luke hooked his legs up and around my waist, to pull me in slightly, and with a slight rearranging I must have found that spot inside him.

"FUCK! THERE!! DADDY!!" Luke screamed as I nudged, prodded, poked, and pressed against that spot. As soon as he screamed that out, something inside me changed. He'd never called me dad before, this was the first time. But it felt right. Except... hearing those words sent an electric shock right to my dick, making it even harder. Why was I so turned on by him calling me daddy? It gave me a second wind, and I focused my attack on that spot deep inside Luke's pussy, my dick slamming into it like a bullseye. It was like that spot was a button that was linked directly to the pleasure centers of Luke's brain.

I leaned forward, our faces so close they could easily touch, staring at Luke's eyes, hooded with lust, heavy with bliss. Our foreheads touched, the tension between our lips was palpable. Like there was an electric charge between us. It just made me fuck him even harder, and after several well-timed thrusts against that pussy spot, Luke broke our contact and melted back into the bed.

The schlupping of Luke's wet pussy was pushing me over. It was somehow getting even wetter, and it created the nastiest squelches I'd ever heard. Like my dick was stirring inside him, rearranging his insides. Luke's pussy squeezed me, milked me, his well-controlled muscles starting from my base and squeezing up like getting toothpaste out of a tube.

This time it took me by surprise. "FUCKING TAKE MY CUM, SON!!!" I roared as I emptied my balls into Luke a second time, my cum pumping into him to the point where some even leaked out of his pussy before Luke could suck it all down, drooling out and over his ass cheeks and onto the bed. Spilling my seed inside a willing pussy. I couldn't help but think that if Luke were a woman, I'm pretty sure I'd be a dad again. Well, now I am a daddy, but in a whole different way. This wasn't just sex, it was mating.

I collapsed onto Luke, my face above his shoulder while his rested against my chest. I didn't dare take my cock out of his pussy yet, worried that it would create another spillage situation. After catching my breath, I pulled myself up and looked into his eyes.

"Are you sure that was ok, Luke?"

"Oh fuck yeah Coach, you treat my pussy so good... fuckin' huge dick." Luke moaned in my ear while he started to grind his pussy onto my somehow still semi-hard cock, making it hard again.

What the fuck was happening to me? Here I was, 38 years old, and fucking and cumming like I was in college. Where was this all coming from, 10 years of pent up sexual tension? How the hell weren't my balls completely empty yet, why did they still feel full?

"Almost Coach, I'm almost there. One more time, I promise, just one more..."

And I wanted to. I wanted to fuck Luke again, to pound another load into him. But most of all I wanted to make him squirt. I needed to.

4 Years Ago

"I just don't get it, Coach!"

It was after Chrissy and Luke cleaned up dinner and loaded the dishwasher. I instituted a "homework after dinner" policy a while back, to keep my three kids- I mean, the three of them, on track. Of course, I had to keep them separated, because Chrissy and Luke would inevitably start teasing each other and bickering. But in an affectionate way, I guess. I knew Chrissy had Luke's back.

I still wondered if Luke would end up together with Chrissy. I guess I hoped, not just wondered. Luke really had become like a son to me - he ate dinner with us more often than not. I helped him out with his homework. I was the male figure he needed in his life to grow up and become a man.

"Alright, tell me what you don't get."

"I don't get any of it, Coach! Like, how can you have a letter in math! I don't understand, like it's all jumbled up."

Luke always struggled with math. Well, really, he struggled with everything. He had a hard time understanding concepts and memorizing facts. I talked with Maria once - she took him to get tested, but then decided she didn't want to do anything differently for Luke. That he was fine the way he was. I agreed with her, and I just hoped Luke would too.

"Maybe everyone is right. Maybe I'm just dumb. Sammy is the only freshman in his Calculus class! And all I can do is catch things and hit things with a bat."

Sammy was Luke's best friend. They met on the team, and have been inseparable ever since. When Luke wasn't eating dinner with us, he was at Sammy's. Sometimes I thought that Sammy was the only real friend Luke had. Don't get me wrong, Luke was friendly with everyone on the team. I know they teased him, but he seemed to take it in stride and laugh along with them. I noticed in middle school that Luke seemed to open up, stop being so shy and quiet. Now he was typically the one leading the team chants.

But, maybe I'm wrong. I didn't know that the guys' teasing affected Luke. I heard them a few times - they called Luke 'bubble boy', 'dumptruck', clearly talking about his butt. During puberty Luke didn't really get much taller, but he started to develop muscle and most of it seemed to be his glutes. Luke always laughed along, though.

"Luke, you don't ever have to compare yourself to anybody. You just have to do the best that you can do. Don't beat yourself up about struggling, even someone like Sammy has weaknesses."

Luke hesitated, but then relaxed a little bit. "Okay, Coach. I'm just gonna try and do the best I can."

"That's the spirit, Luke."

===

The bed was a mess. This cheap motel mattress was now soaking wet, a combination of sweat, pussy juice, and a few drops of my cum that had leaked out of Luke. As much as I wanted to fuck him into the bed, it was honestly too gross.

There was another bed, to be sure, but I had another solution in mind.

"Luke, can you stand?"

He thought for a second, then shook his head. "I don't think so, Coach. My legs are still wobbly and my head is all foggy."

Well, that left me only one choice. I flipped Luke over, hooked my arms underneath his beefy thighs, then lifted him up onto the floor. I wrestled a bit in high school, and the long-lost skills came back as I put Luke into a modified Nelson hold. He was big, and it wasn't exactly easy, but I was strong enough to lift him up and down on my cock.

My cock slips into Luke's pussy for a third time, this time wetter than ever, the tightness loosening up a bit and the sloppy squelches sounding even more obscene. I lifted Luke up and down, my muscles straining, while simultaneously pumping my hips up.

This was fucking hot. Something about this was so... masturbatory. Almost like Luke was one of those sex toys guys would use to get off, those cylinders with the soft insides and fake vagina. But I was never brave enough to get one. Instead, I was using Luke like one, lifting him up and down like he weighed nothing even as every muscle in my body burned. I didn't know how long I was going to be able to keep this position up.

With Luke in this position, I could slam him down so much more forcefully, really piledrive him onto my cock and work at getting it in as deep as I could. The new angle also helped me find even more spots inside Luke that made him go wild. The curve of Luke's ass massaged my cock in a new way, clenching around the root every time I lifted him up before slamming him back down. Every time I did that I matched it with my own thrust upwards, sending my heavy balls slapping against his taint.

Luke was screaming the whole time I'm pumping his jock pussy up and down my cock, of course. And then finally, finally, I feel him grip my forearms so hard he's almost crushing them.

"COACH!! IT'S CUMMING!! MY FUCKING PUSSY IS CUMMING!!"

Luke's eyes rolled back as his pussy just unleashed a torrent of juice, spraying it out over my cock and right onto the already ruined bed. I feel some of it splash onto me, down my legs. His pussy just doesn't stop, it must be pumping out a liter of juice. The slick gushing sounds and Luke's erotic moaning sends me over the edge, and I cum for the third time inside Luke's pussy, so deep it would be in his womb if he were a woman.

After what felt like hours of both of us cumming our brains out, but couldn't have been more than a few minutes, Luke's pussy squirting slowed to a trickle and my balls were thoroughly spent, this time for real. There was not even a drop of cum left in them, and instead Luke had more cum inside of him than a porn star in a six man gang bang.

I looked around the room. We had completely destroyed it. The entire room reeked not only of Luke's pussy juice, but the unmistakable smell of cum. Anybody who walked in would immediately know that sex had taken place. But not just any sex - wild nasty sex. There were cum stains on the sheets and carpet from the remnants that had leaked out of Luke's pussy. His juice had been flung and splattered all over the room, giving almost the entire room a thin sheen of pungent pussy juice.

We were both exhausted, and I slowly lowered Luke to the ground again. His legs were still wobbly, but he seemed to have calmed down.

"Thank you Coach. Fuck that was it. I needed that."

I was relieved. Finally this nightmare was over. And I was happy and somewhat proud that I was the one to be able to help Luke like this.

We were both exhausted, but filthy. I thought about taking him into the shower first, showering together, soaping up his young muscular body while he felt up my middle-aged dad muscles. My cock was thoroughly spent, and gave a slight try at getting hard again, but he was going to be out of commission for a while. I led Luke into the bathroom, hoping the small motel shower would fit the both of us.

1 Year Ago

"Just hold still Luke, we don't need a repeat of you shaving!" Luke kept fidgeting, from nerves, I think. That unfortunately resulted in him nicking himself when he shaved in my bathroom earlier.

Luke took a deep breath and held still so I could finish tying his tie. I took a step back. Where did that little kid go? Standing before me, Luke was a real man. Strong and muscular, more self-assured, more confident. As a junior, he'd finally come into his own.

Before, I couldn't imagine Luke going to the Junior Prom, let alone bring a date. Granted, the date was Chrissy, and I had firmly put away any hope that they would end up dating. They were friends, at least, close to being siblings in fact. That was good enough for me.

"Are you sure you don't want me to drive you? I'm going to head over to chaperone anyways."

"Yeah, it's chill, Coach. Sammy's gonna swing by after he picks up Marissa." Marissa was Sammy's most recent girlfriend, I'm assuming. I had trouble keeping track of them, to be honest. He seemed to have a new girlfriend every week. Meanwhile, Luke had never had a girlfriend, as far as I knew. He always just shrugged it off and said he hadn't met the right girl yet. I knew he wouldn't have any trouble getting one when he was ready, all of Chrissy's friends had massive crushes on him.
