woke up my lil brother(18) by Sucking his cock as a Birthday gift
I had been thinking about it for weeks. Every time Samuel walked past me in those loose basketball shorts, every time he hugged me goodnight with those strong arms that had somehow developed over the past year, every time he looked at me with those innocent blue eyes that had no idea what I was planning.
My little brother Samuel just turned eighteen yesterday, and I knew exactly what I wanted to give him for his birthday. Something he'd never forget. Something I'd been fantasizing about since I caught him staring at my cleavage during a family dinner three months ago.
That night, I'd seen the bulge in his pants when he thought no one was looking. I'd heard him in the shower, taking way too long, and I'd pressed my ear to the door, listening to those soft groans that made my thighs clench together. He was my brother, but he was also a man now, and I wanted to be the one to show him what that really meant.
The night before his birthday, I'd made sure to wear something particularly revealing around the house. A thin tank top with no bra, tiny shorts that rode up when I bent over. I'd watched him struggle to maintain eye contact, watched his hands shake when he passed me the salt at dinner, watched the way his eyes kept drifting down to my chest.
"You okay, Sammy?" I'd asked innocently, leaning forward so he could see everything.
"Fine," he'd croaked, his voice cracking in that endearing way it did when he was flustered. "Just tired."
I'd smiled to myself and gone to bed early, setting my alarm for 6 AM. I wanted to catch him in that delicious state between sleep and waking, when the body responded before the mind could catch up
I woke up before the alarm, my body humming with anticipation. I'd slept in nothing but a silk robe, and I untied it as I crept across the hall to his room. The house was silent, our parents away on their annual anniversary trip. We had the whole weekend to ourselves, and I planned to make the most of it.
His door was slightly ajar, and I slipped inside. The morning light filtered through his curtains, casting soft shadows across his sleeping form. He was on his back, one arm thrown over his head, the sheets tangled around his waist. His bare chest rose and fell with steady breaths, and I felt a rush of heat between my legs.
He looked so peaceful. So innocent.
I wanted to ruin him.
I pulled the sheet down slowly, revealing his boxers. Even in sleep, there was a definite bulge there, and I bit my lip, already imagining what it would feel like in my mouth. I'd been with other guys before, but this was different. This was forbidden. This was everything I'd been craving.
I knelt beside his bed, reaching out to trace my fingers along the waistband of his boxers. He stirred slightly but didn't wake. Good. I wanted him to wake up to the feeling of my mouth on him.
I pulled his boxers down just enough to free his cock. He was already semi-hard, and I wrapped my hand around him, feeling the warmth and weight of him. He was bigger than I'd expected, thick and long, and I couldn't help but let out a soft moan.
"That's right, Sammy," I whispered, leaning down. "Your big sister's going to give you a birthday present you'll never forget."
I took him in my mouth.
He tasted like sleep and skin, and I savored the sensation as I took him deeper. My tongue traced along the underside of his shaft, and I felt him twitch, growing harder in my mouth. A low moan escaped his lips, and I knew he was starting to wake up.
"Mm... what the..." His voice was groggy, confused.
I pulled back just enough to look at him. His eyes were wide, his mouth open in shock as he registered what was happening.
"Shh," I murmured, stroking him slowly. "Happy birthday, baby brother."
"Anya, what are you—we can't—" He tried to push me away, but his body betrayed him. His hips bucked up instinctively, seeking more contact.
"Yes, we can," I said, my voice firm. "I've wanted this for so long, Sammy. I know you have too. I've seen the way you look at me. I've heard you in the shower, touching yourself thinking about me."
His face flushed crimson. "I—that's not—"
"Don't lie to me." I leaned down and licked the tip of his cock, tasting the pre-cum that had beaded there. "I want to hear you say it. Tell me you want this."
He was fully hard now, his cock straining toward me like it had a mind of its own. His hands gripped the sheets, his knuckles white.
"I want it," he finally admitted, his voice barely above a whisper. "Fuck, Anya, I want it so bad. I've been dreaming about this for months."
"That's my good boy," I purred, taking him back into my mouth.
I worked him with my tongue and lips, taking him deep into my throat. He was bigger than I'd anticipated, and I had to relax my jaw to accommodate him. His hands found my hair, tangling in the strands as he gasped.
"God, Anya, your mouth is so—fuck—I'm not going to last—"
"Then don't," I said, pulling off just long enough to speak. "I want to taste you, Sammy. I want you to come down my throat."
I took him again, bobbing my head faster. My hand wrapped around the base of his cock, stroking in rhythm with my mouth. His hips started thrusting up, fucking my face as he lost control.
"I'm close," he warned, his voice strained. "Anya, I'm gonna—"
I moaned around him, the vibration pushing him over the edge. He came with a cry, his hands tightening in my hair as he spilled into my mouth. I swallowed every drop, looking up at him through my lashes as he watched me with wide, disbelieving eyes.
"Fuck," he breathed. "That was... that was incredible."
I pulled off him with a wet pop, licking my lips. "We're not done yet."
I stood up, letting my robe fall to the floor. His eyes traveled over my naked body, stopping at my breasts, then lower to the triangle of dark hair between my legs.
"You're so beautiful," he whispered. "I never thought—I mean, I dreamed, but I never thought it would actually—"
"Stop thinking," I said, climbing onto the bed and straddling his hips. "Just feel."
I positioned myself over him, his cock pressing against my entrance. I was already soaked, my pussy aching to be filled.
"Are you sure?" he asked, his hands gripping my hips. "Anya, once we do this, there's no going back."
"I've never been more sure of anything in my life." I sank down onto him, taking him inch by inch into my wet heat.
We both moaned at the sensation. He filled me perfectly, stretching me in ways I hadn't experienced before. I paused when he was fully inside me, letting us both adjust.
"So tight," he gasped. "Fuck, Anya, you're so tight."
I started moving, rocking my hips in slow circles. His hands moved from my hips to my breasts, cupping them, thumbing my nipples. I leaned forward, bracing my hands on his chest, and rode him faster.
"Look at me," I commanded, and his eyes met mine. "I want you to watch me come on your cock."
His hips bucked up, meeting my movements. The angle was perfect, his cock hitting that spot deep inside me that made stars dance behind my eyes.
"Harder," I begged. "Fuck me harder, Sammy."
He flipped us over, pinning me to the mattress. He was on top of me now, his body covering mine, his cock still buried deep inside me. He started thrusting, fast and hard, and I cried out, wrapping my legs around his waist.
"You feel so good," he groaned, his face buried in my neck. "So fucking good. I've wanted this for so long. I've wanted you for so long."
"Fuck me," I begged, my nails raking down his back. "Don't stop, please don't stop."
He pounded into me, his rhythm frantic and desperate. My second orgasm was building, and I could feel his cock twitching inside me.
"Come with me," I gasped. "Sammy, come with me."
"I'm going to," he groaned. "Fuck, Anya, I'm going to come so hard."
I shattered, my orgasm ripping through me as I screamed his name. My walls clenched around him, and he followed me over the edge, his hot seed spilling inside me as he cried out my name.
He collapsed on top of me, both of us breathing heavily. His cock was still inside me, softening, and I felt a surge of affection for this boy who had just become a man in my arms.
"Happy birthday," I whispered, kissing his forehead.
He laughed, burying his face in my neck. "Best birthday ever."
"Don't get too comfortable," I said, a wicked smile playing on my lips. "We have the whole weekend."
He lifted his head, his eyes wide with anticipation. "Seriously?"
"Seriously." I pushed him onto his back, climbing on top of him again. "I'm not done with you yet, baby brother. Not even close."
He grinned, pulling me down for a kiss. "Then show me what else you've got."
And I did.
We spent the rest of the weekend exploring each other, learning every inch of each other's bodies. There were no regrets, no guilt, just the overwhelming rightness of being together. We knew it was forbidden, that our family would never understand, but we didn't care.
We loved each other in ways we'd never been taught were wrong.
And for the first time in our lives, we both felt truly whole.
