Watching His Ass Bounce On Her — Chapter 4 [Finale]

Everyone is 18.

Chapter 4: The Final Line [Finale]

Grant took longer to return than normal, and when he appeared in the doorway, a big smile crawled across his face. He looked at our naked bodies, erections standing proud.

“Nice,” he said, walking toward us and dropping his robe, “party’s still goin.”

He stood in front of us, his large manhood growing thicker as he watched us drool over him. Eli and I dropped to our knees preemptively, eager and obedient. Until recently Grant had just been a friend, but being exposed to his sexual prowess after I stumbled upon his public sex in the showers at school opened up a new side of me. Within a couple days he was inviting me to watch along with his brother Eli, and then it escalated to having... afterparties.

"Who wants to taste her first?" Grant teased.

Eli stayed still on his knees, his own big rod sticking up in the air, twitching slightly as he watched Grant approach. I looked up, my mouth already watering, and opened it instinctively, letting Grant plop his big balls onto my tongue and his hard shaft on my face. The heat and weight of him felt intoxicating, and I was immediately lost in the moment, licking his balls like a zombie in a trance. His musk filled my senses, and I couldn’t get enough of it. My hands instinctively reached up to grip his thighs, steadying myself as I worshiped him.

Grant groaned low in his throat, clearly enjoying the attention. He shoved his fingers into Eli's mouth first, then mine, and I sucked hard, savoring the musky taste of his skin. His fingers pressed against my tongue, and I could feel the roughness of him, a reminder of his strength and dominance. 

"Yeah, get her all off me," he growled. His kink, whether he realized it or not, was definitely being worshiped, having lesser males honor him for his conquests with the hot girl. I held my own with the girls, but the first time I ever felt inferior was when I saw Grant fuck.

He pulled his fingers out of my mouth and grabbed the back of my head, guiding me back to his balls. I obeyed without hesitation, licking and sucking them eagerly, my tongue swirling around the sensitive skin. Eli, meanwhile, had moved closer, his hands resting on Grant’s hips as he leaned in to lick at the base of Grant’s shaft. The sight of us both servicing him seemed to drive Grant wild, and he let out a deep, guttural moan, almost like a purr.

"Good boys," Grant muttered, his voice indicating approval. He reached down and ran his fingers through my hair, tugging gently but firmly as he guided my mouth back to his cock. I took him in eagerly, my lips stretching around his girth as I bobbed my head up and down. Eli continued to work on his balls, his tongue flicking and lapping at the sensitive skin. The room was filled with the sounds of our worship, wet slurps, masculine groans, and the occasional slap of skin against skin, squishing his shaft and plopping his wet balls onto our faces.

Grant’s breathing grew heavier, and I could feel his cock throbbing in my mouth. He pulled out suddenly, leaving me gasping for air, and turned his attention to Eli, pushing his head down onto his cock. Eli took him eagerly, his lips wrapping around Grant’s shaft as he began to suck. I watched in awe, my own cock aching as I saw how completely Eli submitted to him. Eli’s eyes showed that he felt like me, utterly incapable of saying no to him. Grant’s hand rested on the back of Eli’s head, guiding him up and down, and I could see the pleasure written on his face.

As Eli worked on Grant’s cock, I moved lower, pressing my face into Grant’s taint and licking at the sensitive skin there. Grant let out a sharp gasp, his hips bucking slightly as I explored this new territory. My tongue traced the line between his balls and his ass, and I could feel him tense up. 

"Fuck," he muttered, "You two are fucking amazing."

The praise sent a surge of pride through me, and I redoubled my efforts, determined to please him in any way I could. Eli and I worked in tandem, our mouths and tongues moving in harmony as we worshiped Grant. It was an intimate, almost sacred act, and I could feel the power dynamic reaffirming itself with every moan and gasp that escaped Grant’s lips. We were his, completely, and there was no going back.

Grant assertively, yet gently, pulled Eli to stand behind him. He guided Eli’s face toward his ass, and Eli took to it like he’d done it before, eagerly eating him out while holding his hips for balance. Grant turned his attention back to me, sliding his cock into my mouth. I tasted the still lingering tang of pre-cum and sex, a mix that made my head spin.

Grant held both of our heads in place, alternating between us. He stretched my throat with his thick length, the burn and sting only fueling my submission. He pushed me back slowly as he held my head, forgetting about Eli behind him. Soon, I had no choice in the matter, and I loved it. He was fucking my face as I lay back on the bed, completely at his mercy. His stamina was unreal, and he avoided cumming by pulling out intermittently to let me nurse his balls in my mouth before battering my throat again.

I was too overwhelmed to even think about jerking my own aching boner. Eli, meanwhile, shyly approached Grant’s feet, massaging them before licking and sucking on his toes while edging himself.

Eventually, Grant laid back, letting us take turns. Eli and I blew him, ate out his ass, sucked his balls, and licked his armpits. Anything to please him. His comfort zone, however, was being in control. 

After a couple minutes, he got up and put us back on our knees, positioning us like obedient pets ready to serve. He stood tall, his cock glistening with a mix of spit and pre-cum, and he looked down at us with a smirk, and grabbed the back of Eli’s head first, guiding him onto his shaft with a firm hand. Eli took him eagerly, his lips wrapping around Grant’s length as he bobbed up and down. I watched, my own mouth watering, as Grant’s cock disappeared into Eli’s mouth, only to reappear slick and shiny moments later. He was rougher now, treating Eli’s neck like it was an inanimate toy. 

Then it was my turn. Grant pulled Eli off with a wet pop and turned to me, his eyes darkening. He didn’t need to say anything. I opened my mouth instinctively, letting him slide his thick cock past my lips, resetting my comfort zone. The taste of him was just as intoxicating the tenth time as the first, a mix of musk and salt that made me forget about anything else in the world. He thrust into my mouth with precision, each movement calculated to hit as deep as possible. I felt like he was going to literally enter my stomach as I held his hips for support. I gagged plenty, but I didn’t pull away. I wanted this, and I wanted to please him, to feel him use me however he saw fit.

Grant alternated between us, fucking our faces with a calculated rhythm, clearly aimed to maximize his stamina. Eli and I were breathless. One moment, Eli was deep-throating him, his cheeks hollowed out as he sucked hard. The next, Grant was pushing his cock into my mouth, his hips driving forward until I felt him stretch my body again. The sounds were obscene, wet slurps, muffled moans, and the occasional gasp for air. It was overwhelming, but I loved every second of it. I could feel myself getting harder just from the way he dominated us, his control over our bodies absolute. His balls reaching my chin felt like an achievement every single time they made contact.

At one point, Grant pulled out of Eli’s mouth and leaned down, spitting directly into mine. The warm glob of spit landed on my tongue, and I swallowed it without hesitation. 

“I bet you can still taste her in my spit, huh?” he growled. “That’s right, pussy boy.” 

His words sent a jolt of humiliation through me, but it only made me more eager to please him. I looked up at him with wide eyes, my lips parted as I waited for his next command.

Grant chuckled, sort of darkly, clearly enjoying the effect he had on me. He grabbed my hair and pulled me back onto his cock, thrusting deep into my mouth as if to remind me of my place. Eli watched from the side, his own cock twitching as he waited again for his turn. When Grant finally pulled out of my mouth, he turned to Eli and spat on him too, marking him just as he had marked me. Without words, it felt like he was saying it all. You’re both mine now.

We were too far gone, too consumed by the need to serve him to do anything but submit. Grant continued to fuck our faces, alternating between us with a rhythm that left us both gasping for air. Just from the irregular rubbing against my own thighs, I could feel myself getting closer to the edge, my own cock aching and throbbing, but I didn’t dare touch myself. This wasn’t about me. This was about Grant, about making him feel good. And as he looked down at us with that same smirk, I knew we had succeeded.

We had completely devolved into worship zombies. And I think he liked it even more than sex with the girl. We carried on like that for a while, until he escalated it further.

—[]—

Grant pushed me onto my stomach, his strong arms firm as he pulled apart my cheeks. No words were needed. His dominance was clear, and I leaned into it willingly, my body trembling. “Do whatever you want to me,” I whispered, my voice barely audible over the pounding of my heart. It was the first time I had said the words out loud, but he didn’t even react. He already knew.

He placed a strong hand on the middle of my back, pinning me in place as he angled his body against mine. I could feel the heat of his cock pressing between my cheeks, slick with spit and pre-cum, throat juices and sweat. I braced myself for what was coming.

When he pressed forward, I felt my hole stretch for the first time, a sharp, unfamiliar sensation that made me gasp. But the only thought in my mind was making Grant feel good. It consumed me completely, driving out any hesitation or fear. He pushed deeper, his thick cock stretching me in ways I’d never imagined, and I clenched my teeth against the pain. This is what I wanted, I reminded myself. This is what I needed. His hips moved slowly at first, testing my limits, and I could feel every inch of him as he filled me. The pressure was intense, honestly overwhelming, but I didn’t pull away. I wanted this, and wanted him, more than anything.

Within minutes, the initial pain began to fade, replaced by a strange, numbing pleasure that radiated through my body. I reached back blindly, my fingers finding his hip, and I guided him deeper, urging him to take more of me. Grant groaned above me, his breath hot against my neck as he picked up the pace. Each thrust sent shockwaves through me, and I could feel myself surrendering completely to him. This was it, I thought. This was what it meant to be claimed. I had watched him fuck so many girls, envied the way he took them, and now it was my turn. The realization sent a thrill through me, and I moaned softly into the sheets.

Eli watched from the side, his own cock in hand as he stroked himself furiously. His eyes were locked on us, and I could see the hunger in his gaze. His gaze only fueled my submission, and I arched my back, giving Grant even more access. Eli’s hand moved faster, and soon streaks of jizz were spilling across my sweaty back, marking me as meaningfully as Grant’s cock inside me. The sensation of his cum on my skin was strangely elevated, and I felt a surge of pride knowing that I had driven him to that point. 

Eli reached down and grabbed my throbbing red cock, which was leaking a string down to the bed. He started rubbing it slowly, and I was in heaven. I heard myself moan like a girl, in a way I didn’t even know I was capable of.

Grant’s thrusts grew harder, more urgent, and I could tell he was close. His grip on my hips tightened, and he let out a hot breath against my ear as he finally came. Eli squeezed my cock one last time, and I pulsed and squirted out onto the sheets. My body was weak and I barely held myself up as my head swam with sensations. Grant’s release was hot and heavy inside me, filling me in a way that felt both intimate and possessive. My body shuddered, overwhelmed by the intensity of the moment. We had crossed a line, one we could never come back from, but in that moment, I didn’t care. I was his. And nothing else mattered.

As Grant pulled out, I collapsed onto the bed, my body trembling with exhaustion and satisfaction. He didn’t say a word, but I could feel his eyes on me, his presence still dominating the room. Eli lay beside me, his breathing ragged as he recovered as well. I knew this moment would stay with me forever. We were bound together now, not just by friendship, but by this primal urge we had released with each other. And as I lay there, spent and content, I couldn’t help but wonder what would happen next.

We got dressed in silence, the lingering energy of what had just happened rocking my brain, and probably theirs too. Grant didn’t say a word, which was unusual for him. Normally, he’d crack a joke or make some comment to break the tension, but this time, he just stood there, pulling on his clothes with a quiet intensity. I could tell he was satisfied, more than ever before. There was a smugness in the way he moved, a confidence that radiated from him like heat. He didn’t need to speak; his body language said it all.

I glanced at Eli, who was avoiding eye contact as he tugged on pajama pants. His face was flushed, and his hands trembled slightly as he buttoned his jeans. I wondered what was going through his head. He and Grant shared a room, after all. Would things be different between them now?  Or would this become their new normal? Was this even new to them, or just to me?

The idea of all the possibilities gave me energy. I couldn’t imagine what it would be like to live with someone who just… claimed you like that. But then again, Eli wanted it as much as I did.

As I slipped on my shoes, I caught Grant’s eye for a brief moment. He smirked, that same cocky grin that always made my stomach flip, and gave me a nod. It wasn’t a thank you. It was an acknowledgment. A silent reminder that this wasn’t over. That he’d call on me again when he wanted to, and I’d come running. I felt a strange mix of pride and submission wash over me. And I didn’t want it any other way.

I let myself out of the room, the door clicking shut behind me. The house was quiet, the only sound the soft creak of the stairs as I descended. But then, just as I reached the bottom step, I heard it, a faint, rhythmic smacking sound coming from upstairs. I paused, listening intently. The sound was unmistakable, accompanied by muffled groans that sent a jolt of heat straight to my core. Should have known they weren’t done.

I stood there for a moment, torn between curiosity and guilt. Part of me wanted to go back, to see what would happen next, to join in again. But another part knew that maybe they needed some privacy. So I forced myself to keep walking, even as my mind raced with images of what might be happening in that room. Grant and Eli. Together. Without me. The thought was equal parts thrilling and torturous. Guys only regret the times they didn’t have sex.

By the time I reached the sidewalk outside, my hands were shaking. I sat there for a while, staring at the dark house, wondering if I’d ever be able to look at either of them the same way again. Probably not. And honestly? I didn’t want to. Whatever this was, whatever we’d become, it felt right. Like we’d crossed some invisible line and there was no reason to go back. As I walked away from their house, the sound of their moans still echoing in my mind, I couldn’t help but smile.
