This is part 1 of the Sister’s Orgasm series.
*****
It was summer, and Mom was away. I was in my room playing Counter-Strike, fully locked in. My older sister was home too, though I had no idea what she was doing.
She suddenly opened the door, making me lose focus and get shot in the head.
“Savannah, fuck off,” I said, throwing the headset at the screen.
“Wow,” she replied. “Someone woke up on the wrong side of the bed.”
“Learn to knock.”
“Jeez, it’s not a big deal.”
I spun my chair around to face her. Standing at five feet nine, she stood there with long, angel-blonde hair, her boobs straining against a tight white top, paired with a pink mini skirt. She was slim, which made her tits look bigger, and she had a cute face that I could stare at for days. My older sister was hot. I wasn’t embarrassed to admit it.
“You’d freak out if I barged in on you like that,” I said.
“Uh-uh,” she replied, shaking her head. “So how long are you planning to sit here?”
I shrugged. “I dunno. I’ll probably do some DoorDash later.” We weren’t exactly well off, so I had to bring in money however I could. My sister made good money modeling, and our mom worked as a secretary.
“Can you grab something for me?” she asked, tilting her head and giving me a puppy-dog look.
“Sure. What do you need?”
“A couple of lipsticks,” she said. “My favorite brand just dropped a new flavor.”
“Isn’t your cabinet already full of them?”
“No. Only, like, half full. So are you helping me or not?”
“Yeah, sure,” I said. “Text me the store and the exact name.”
She stepped forward, pulled me up out of my chair, and wrapped her arms around me. Her tits pressed firmly against mine as she hugged me tight.
“Thank you so much,” she said.
“A bit too tight.”
She stepped back and grabbed her purse from the dresser.
“Here,” she said, pulling out some cash and handing it to me. “Get the lipsticks. Keep the change.”
I glanced at the bills. It was more than I expected. “This is a lot.”
“They’re expensive,” she said with a shrug. “You deserve the extra.”
I didn’t argue. I grabbed my keys and headed out, already thinking about how much DoorDash I could skip tonight with that kind of tip.
The lipstick turned out to be ridiculous in price. Tiny tube, fancy packaging, some brand I had never heard of. Still, when I paid, there was enough left over to make the trip worth it. I felt stupidly good about it as I drove home.
When I got back, the house was quiet. I slipped inside and kicked my shoes off, then froze. A sound drifted down the hallway. Someone was moaning … as if being pleasured.
I stood there, heart suddenly pounding, listening. It was coming from my sister’s bedroom. The door was closed, but not all the way. The sound rose again, slow and unaware.
She had no idea I was back.
I swallowed, the bag with the lipstick crinkling slightly in my hand as I stood there, torn between announcing myself, doing nothing at all … or walking in and having a peek.
Heat rose in my face as I stood frozen in place. The sound came again, a little louder this time, as if she’d reached a sensitive spot. Either she was watching pornos or she was masturbating. Something stirred in me, curiosity, arousal and shame, all mixed together as I took a silent step toward the hallway.
I knew I should announce myself. Clear my throat, drop something … anything to make my presence known. Instead, I found myself moving quietly down the hall, the shopping bag clutched tightly in my sweating palm.
The door to Savannah’s room was cracked open just enough that light spilled into the hallway. Another moan drifted through the gap, followed by a gasp. My cock awkwardly stiffened as I inched closer, drawn by sounds I had no right to hear.
Through the narrow opening, I could see her bed. Savannah lay sprawled across it, her laptop balanced on her thighs. The blue glow of the screen illuminated her naked body as her hand moved between her legs. I should have looked away. Should have backed up, but I couldn’t move.
She was completely nude, her clothes discarded on the floor beside the bed. Her breasts were at the peak of their beauty, round and perky like teardrops, rising and falling with each heavy breath she took. I’d never seen her like this before. Never seen any woman like this, for that matter.
Her fingers glistened as they slid through the folds of her sex, pink and symmetrical, glistening wet in the laptop’s light. On the screen, two women were locked together, tongues exploring each other’s pussies. It was lesbian porn, and they were in a sixty-nine position.
So she was doing both what I suspected her of, masturbating and watching porn.
Savannah brought her fingers to her mouth and sucked them clean, her eyes never leaving the screen. The sight was so hot that it hardened me instantly. I pressed my palm against the front of my jeans, trying to ease the building pressure.
She returned her wet fingers to herself, circling and stroking as if she’d done this a million times before. Her breathing quickened, interrupted by soft moans that grew more desperate with each passing moment. She really wanted that orgasm.
I couldn’t look away. Couldn’t move. My cock and balls had become painful, straining against my zipper. The pressure built with each of her movements, each sound she made.
Without warning, she reached toward her nightstand and grabbed something, a vibrator. She slid it inside herself with a long, satisfied sigh, her other hand continuing to rub and massage her clit in tight circles. The buzz of the device mingled with her increasingly vocal pleasure.
“Oh god, yes,” she whispered, her back arching off the mattress.
Her thighs began to tremble, her stomach muscles tightening. And then she was coming, her entire body tensing, head thrown back, and a cry escaping her throat as waves of pleasure visibly coursed through her.
When I saw her climax, I wasn’t sure what happened. Whether it was some kind of sibling magic, my cock became so sensitive, and I squirmed where I stood. Then, without even touching myself, I felt the hot pulse of my own come flooding my underwear. I came hard, the intensity of it nearly buckled my knees.
Reality crashed back like a bucket of ice water. What the fuck was I doing? I had to get out of there before—
“Jason, what the fuck!”
Too late. Savannah’s eyes locked with mine through the doorway. She slammed her laptop shut and scrambled to cover herself.
“Are you fucking spying on me?” she shouted.
“No! I—I just got back with your lipstick,” I stammered, holding up the crumpled bag as pathetic evidence.
“You pervert!” She grabbed a throw blanket, wrapping it around herself. “Why didn’t you say something? Why were you watching me?”
“I didn’t mean to! I heard a noise and—”
“Close the fucking door!” she screamed, throwing a pillow that hit the door with a soft thud.
I backed away, mortified and sticky, retreating to my room where I changed quickly, my hands shaking with adrenaline and shame. What had I done? How could I face her after this?
Twenty minutes later, she knocked on my door. Savannah stood there in her bathrobe, arms crossed tightly over her chest.
“Can I come in?” she asked, her voice surprisingly calm.
I nodded, unable to meet her eyes.
She sat at the edge of my bed. “Look, that was… not cool.”
“I’m sorry,” I mumbled, staring at the floor. “I should have announced myself. I just… I don’t know what happened.”
She gave me a look. “Right.”
“Here,” I said, handing her the shopping bag. “Your lipsticks.”
She took it, examining the contents briefly before setting it aside. “Thanks.” She sighed heavily. “You know, I’ve heard you too. Through these thin walls.”
My face burned hot. “What?”
“When you think no one’s home. You’re not exactly quiet.” A small, uncomfortable smile played on her lips. “We’re even, I guess.”
“That doesn’t make it okay,” I said, finally looking at her. “I shouldn’t have… we’re siblings.”
“Who cares … this stays between you and me, right?”
“I promise,” I said, feeling relieved.
She stood and gave me a warm hug. “Thanks for getting my stuff.”
As she embraced me, I caught her scent, which was sweet and musky. When I felt her sticky hands on my back, I realized she hadn’t washed them.
“We’re good?” I asked.
“We’re good. Just… knock next time, okay?”
“So should you,” I teased her.
She stuck her tongue out and blew me a raspberry. “Love you,” she said before closing the door.
“Love you too, sis.”
She left, closing my door behind her.
