I helped my sisters BF cum -Part 3

Everyone in this story is 18+

Days later, I heard a knock on my door. My stomach tightened when I saw who it was—Allison, my sister. Framed in the doorway like some sort of perfect mean girl, her perfect blonde hair pulled back into a sleek ponytail. If I weren’t related to her, or totally gay, I’d probably be crushing on her.

“Samuel,” she said, using my full name like she always did, which annoyed me to no end. Nobody else called me that,  and she knew it annoyed me. She liked to remind me I was different, as if I didn’t already feel that way.

“Hey, Allison,” I replied, shifting on my bed and trying not to roll my eyes.

She flounced into the room, wrinkling her nose at my messy space. “Ugh, this place looks like a tornado hit it. Seriously, Samuel, how can you live like this?”

“It’s not that bad. I’ll clean up later.”

“All you ever say is ‘later,’” she sighed dramatically, glancing around as if something might attack her. “But that’s not why I’m here.”

“Then why are you here?” I raised an eyebrow, mildly curious.

“Just checking in on my little bro. How are you?” she asked, smudging her lip gloss.

“Actually, some guys at school have been teasing me, and I feel—”

“Sorry, but you’re just too tedious. I really need to talk to you about something serious.”

“Uh, okay?” I responded, sensing a headache coming on.

“It’s kinda embarrassing, but I can’t bring it up with Mom or the girls. And since you have no social life, I trust you’ll keep it to yourself,” she said, brushing an imaginary piece of lint off her leggings.

“Go on,” I said, still unsure where this was headed.

“Julian,” she dropped the name like it explained everything. “He’s been acting needy lately, and I think it’s because I don’t really like... you know, doing things with him.”

“Uh... like what things?” I asked, my stomach tightening.

Allison bit her lip. “Like sex stuff. I don’t like it when he... finishes on me. It’s just gross. I hate the way it feels.” She shuddered. “And I think it’s starting to annoy him.”

I tried to keep my face neutral, fighting back a flood of thoughts. “Oh.”

“It’s not that I don’t care about him,” she continued, twirling a strand of hair. “But it just freaks me out. It’s so messy and gross, you know?”

“Yeah, I get that,” I replied slowly.

“He doesn’t say anything, but I can tell he’s disappointed. Why do guys have to be so complicated?”

“Honestly, you shouldn’t do anything you’re uncomfortable with. If you don’t like it, don’t feel pressured to deal with that,” I advised cautiously.

She looked at me, surprised. “Yeah, you’re right. He’s perfect in almost every way, but this is just awkward.”

“Totally. You shouldn’t feel forced into anything.”

“Exactly,” Allison said, sitting up straighter. “Thanks, Samuel. I don’t know why I bothered talking to you, but... you’re surprisingly not useless for once.”

“Glad I could help,” I said, resisting the urge to roll my eyes.

“Anyhow! I’m gonna take a facial. I want to look my best for Julian.”

“Yeah, I think I’ll get one too,” I smirked.

“That’s great, Samuel. You really need it. You look so bland and dull.”

 A facial from your boyfriend, you cow! I thought, as I continued to smirk.

With a quick, dismissive smile, she stood to leave. “And clean your room. It’s gross in here. God, how do you live like this?” She wrinkled her nose at the mess before walking out the door without waiting for a response.

I lay back in my bed, staring at the ceiling, thoughts racing through my mind. Would I get another chance to help Julian get off? Just the thought sent a rush of heat through me, and I could feel myself chub up.

Later that night, anticipation gnawed at me. I could hear them watching a movie, Allison rambling on about herself, even mentioning how ‘sad’ I was for not going out on a Saturday. But I didn’t care; I had my own plan to get back at her.

When I finally heard them getting busy during their second movie, I wasted no time. This time, I was ready for him. I listened intently as Allison's moans echoed through the thin walls, sounding almost theatrical—like a pornstar in heat. She always had a flair for the dramatic. Moments later, I heard the familiar rustle as she got up and made her way to the shower.

Anticipation coiled tightly in my stomach, a thrilling mix of excitement and nervousness. I quickly positioned myself, sitting cross-legged on my bed, feigning interest in my phone while my senses sharpened, listening for any sign of a knock. I heard the shower start in the bathroom.

Then I finally heard it: a soft knock on my door that sent my heart racing. My breath caught in my throat; it could only be one person.

"Sammy, can I come in?" Julian's voice was low and urgent, tinged with a hint of desperation.

I didn’t hesitate for a moment, "Yeah, come in," I called out, my voice barely above a whisper.

The door creaked open, and there he stood, just as tall and imposing as ever. His tanned skin glistened under the warm light streaming through the window, and his brown eyes were filled with a mix of frustration and anticipation. He wore only a pair of boxer briefs that hugged his body tightly, emphasizing the thick bulge straining against the fabric.

"Hey, Sammy," he said, stepping into the room and shutting the door behind him with a soft click. "Your sister... she left me hanging again."

I bit my lower lip, feeling my cheeks flush. "What do you need, Julian?" I asked, trying to sound casual, even though my heart raced like a drum in my chest.

He took a step closer, overwhelming the small space between us. The warmth radiating from him thickened the air with tension. "You know... what I need," he replied, his voice heavy with desire. "Last time, you helped me out. Can you do it again? But this time… I want more."

My breath caught in my throat. "What do you mean, more?" I managed to ask, my voice trembling slightly.

Julian's eyes darkened with lust, a predatory glint flickering within them. "I want you to... suck me off, Sammy. Please."

The request hung in the air like a charged bomb, ready to explode. It was exactly what I wanted, and I nodded slowly.

Julian’s lips curved into a relieved smile, unrestrained eagerness crossing his face. "Thank you, Sammy," he murmured. He hooked his fingers into the waistband of his boxer briefs and slowly pulled them down over his hips, revealing himself to me. My mouth watered at the sight, an intoxicating mix of excitement and nervousness coursing through me.

His dick jutted out proudly, thick and veiny, the head already glistening with precum. My breath hitched as I stared at it, my body trembling with anticipation.

"Come here," Julian whispered, guiding me to the edge of the bed. He sat down beside me, his cock standing erect inches from my face. I could feel the heat radiating from it, smell the faint musk of his arousal.

"Take it in your hand," he instructed softly.

I obeyed, wrapping my fingers around his shaft. The texture was smooth yet firm, and I marveled at how perfectly it fit in my grip. My thumb instinctively brushed over the tip, smearing the precum across the sensitive flesh. Julian groaned, his hips bucking slightly into my hand.

"That’s it, Sammy," he breathed. "Now, put it in your mouth."

My heart pounded as I leaned forward, my lips parting to accept his length and girth. The first touch of his cock against my tongue made me tremble even more. I closed my lips gently around the head, sucking lightly as I began to slide my mouth down his shaft.

Julian’s breath hitched, and he let out a low, guttural moan. "Fuck, Sammy... that feels so good."

Encouraged by his reaction, I moved faster, taking more of him into my mouth with each pass. My lips slid up and down his length, my tongue working over the underside as I hollowed my cheeks to create suction. Julian’s hands found their way into my hair, threading through the silky strands as he guided me along his cock.

"Suck it harder, Sammy," he urged, his voice strained. "Make me cum."

I complied, tightening my grip on his base and increasing the pressure of my mouth. My nose brushed against his pubic hair with each downward stroke, and I could feel the veins pulsing beneath my tongue. Julian’s moans grew louder, filling the room with the sound of our shared pleasure.

"Oh God, Sammy... almost there," he panted, his hips thrusting rhythmically into my mouth. I quickened my pace, desperate to bring him to the edge. My jaw ached slightly, but the sensation of Julian’s cock throbbing in my mouth was too intense to stop.

Then I remembered my plan to get back at my sister. I pulled away, and Julian looked half-annoyed. “I want you to cum all over my face,” I said, a wicked grin spreading across my face. His expression shifted, revealing unrestrained excitement. “On your knees then.”

I immediately complied, dropping to my knees as he stood before me.

I put my mouth over Julian’s wet dick again, bobbing up and down once more. Julian’s grip tightened in my hair, pulling me closer. "Here it comes, Sammy," he groaned, his voice breaking.

A surge of warmth flooded my mouth as Julian came, his cock twitching and spasming with each pulse of his orgasm. I swallowed reflexively, the taste of his cum filling my senses. It was salty and tangy, and as he began jerking himself, I extended my tongue to catch more of the spurts, some hitting my face and splattering on my skin.

The amount was unlike anything I had seen in porn, his head falling back as he exhaled deeply. "Fuck... that was amazing, Sammy," he murmured, his voice thick with satisfaction.

His cock softened, and I wiped the corner of my lips with the back of my hand. My body buzzed with the aftermath of our encounter, my mind swimming in the intensity of the experience.

I reached for some wipes I had conveniently stored under my duvet and cleaned myself up.

Julian, still catching his breath, turned to look at me, his eyes filled with a mixture of gratitude. "Thank you, Sammy, and sorry again if it was too much," he said, his voice softer now. "You’re incredible. You actually seem to really enjoy this; it’s so fucking hot!"

Before I could respond, he leaned in and pressed his lips to mine in a tender kiss. The taste of his cum still lingered on his lips, an intoxicating reminder of what we had just done.

Then he stood up. “I have to go now before Ali comes back. But Sammy... you have to let me fuck you, please!”

A thousand thoughts raced through my mind at once, and I could only say, “Julian, don’t forget your boxers.”

He glanced at them, picked them up, and cleaned his cock of my saliva and his cum, then dropped them. “A gift if you just say yes.”

“Yes?” I tried to act coy.

He raised his eyebrow. “Sammy, you know what I want.”

I heard my sister start the washing machine, a ritual she often performed before coming out of the shower.

“Yes.” I smiled, utterly entranced as I saw him turn, noticing his cute, muscular, and slightly hairy butt. I couldn’t help but chuckle at the sight of his nuts swaying and bouncing as he started to jog into my sister’s room.
