Sister’s Dildo

I’m not saying my sister and I were close, but our parents’ idea of “two college kids sharing a house” was basically: ignore each other until dinner and then re-fracture into bedrooms with doors shut. My point is, Nadia and I had spent the summer practically as strangers. Which is why, when I went to shower that Sunday morning and found her pink dildo suction-cupped to the edge of the tub, it felt less like a crime against decency and more like a cryptid sighting.

I actually did a double take. At first, I thought it was some kind of new-age shampoo bottle, because who just leaves their sex toy right there, in the open, unless they want it found? But no. I reached for the hot faucet and nearly elbowed it. The thing was veiny, cartoonish, and looked like the exact opposite of the kind of guy my sister said she dated. No mistaking what it was, though.

My brain, which had been operating at lizard-level for most of the week, did the obvious math: Nadia, in here last night, what, getting herself off with this thing while I played Fortnite across the hall? The realization hit me in the chest … then, lower.

I got hard instantly, which was the most humiliating thing, even alone.

Instead of showering, I stood there holding the fake cock, thumb on the balls, my dick straining against my mesh shorts, imagining Nadia riding this thing. I knew how she moaned when she thought nobody was home, how her bedroom door clicked at one a.m., how she always came out for water looking like she’d just run a marathon. My sister. Naked, flushed, grinding herself down on a dildo so brazenly left out it must have been intentional.

I should have dropped it, left the bathroom, or at least finished jerking off in private. But I couldn’t stop looking. Couldn’t stop thinking about how much of her I’d accidentally seen over the years: side boob, panties, even once a full glimpse of her tits through the cracked closet door, but never anything like this.

I headed into the shower and turned on the water. A bead of water ran down the shaft as the shower heated up. I flicked it off and pressed the toy against my own hip, as if comparing. It was longer, obviously, and a little thicker, but the head was shaped like mine. I’d never thought to imagine how Nadia saw a dick, let alone what she wanted inside her, but apparently it was something pretty close to what I had. The weird, forbidden pride in that made me harder.

Eventually, I managed to shower, but my mind was stuck in a loop. Rinse, lather, picture Nadia, picture Nadia, stroke myself under the water and feel like a scumbag. I didn’t even try to come, just scrubbed off and towelled dry, still sporting wood. I had to get it together. My whole body felt shaky.

I left the bathroom in my towel, the toy still attached to the edge of the tub like a middle finger, and padded down the hall to my room. At first, I planned to forget the whole thing, but as I passed Nadia’s door I heard her inside, voice muffled, probably on the phone. A vision of her, last night, knees up on the edge of the tub, toy buried inside her, sent a shock through my body.

I wanted to see her. Not in a normal, brotherly way, but I wanted to see her face when I handed her the dildo. Would she deny it? Laugh it off? Would she blush, look away, act like I was the perv for noticing?

The towel was still wrapped around my waist, half-cocked. I grabbed the dildo from the tub and knocked on Nadia’s door with it.

No answer.

I knocked again, this time with my knuckles. “Hey. Nad. You left something in the bathroom.”

A scuffling noise, then her voice, tight and defensive. “Go away.”

“I’m serious, it’s kind of hot.”

She opened the door just a crack. Nadia had a cute, soft face: big eyes, light freckles across her nose and cheeks, and a mouth that always looked like it was about to smile or bite her lip. Her hair was in a loose ponytail and she wore an old sweatshirt, sleeves pulled over her hands like she was hiding. Her cheeks were already splotched pink, eyes wide with something between annoyance and terror.

“What,” she said, monotone, but her gaze snapped to the thing in my hand. “Oh my god, give it to me.”

I held it out, shaft-first, and smirked. “You want it back that bad?”

“Shut up,” she hissed, snatching at it. She missed, so I held it above her head.

“Relax, Nadia. I’m not judging. Just, like, clean up your stuff next time. I almost used it as shampoo.”

She scowled and took another swipe, but this time her arm brushed the towel at my waist. Her knuckles grazed my bare hip and her eyes flicked downward, noticing, maybe, the outline of my dick pressing against the towel. I let her stare.

“You’re such a dick,” she muttered, grabbing the dildo with both hands and yanking it free. She made a show of looking disgusted, but her ears burned scarlet. “You ever heard of privacy?”

I shrugged. “You ever heard of subtlety?”

She started to slam the door in my face, but I blocked it with my foot.

“Wait,” I said. “Just…be more careful, okay? Mom’s soon home.”

She hugged the dildo to her chest, like it was a security blanket, and mumbled, “Whatever.” But she didn’t shut the door this time. Instead she just stood there, breathing heavy, looking at my chest and then the toy and then back up to my face. There was a moment, maybe half a second, when I felt like I could say anything and she’d listen.

I didn’t say anything, though. I just stood there, towel tenting, heart jackhammering.

She broke first. “You can leave now.”

I let the door close, walked to my room, locked it, and stared at the ceiling for what felt like an hour. My dick was still hard. I considered jerking off, just to get it over with, but it felt cheap, like if I waited something even better might happen. I don’t know why I felt that way, but I did.

Maybe ten minutes later, Nadia knocked.

I opened the door. She had changed out of her sweatshirt and was in a thin tank top and tiny shorts, braless. The pink had faded from her cheeks, but her arms were crossed, toy hidden behind her back.

“What?”

She looked at the floor. “I need a favor.”

I blinked, waiting for the punchline.

She bit her lip. “You already saw it. You know what it’s for. My hand’s sore, okay? I can’t, um, do it myself today.”

I wanted to laugh. Was this a dare? Some kind of payback for teasing her?

She peeked up at me, just for a second. “I know it’s weird. But could you…?”

She trailed off, then pulled the dildo out from behind her and offered it to me, handle-first.

My eyes widened. “You want me to use this on you?”

Her voice was a whisper. “If you want. If not, I’ll figure it out.”

I took the toy from her, holding it like a loaded gun. “Where?”

She jerked her head back toward her room. I followed, feeling like I was about to walk onto a game show, only the prize was my sister’s dignity and maybe my own.

Her room was tidy, except for a nest of blankets on her bed. She sat on the edge and looked up at me, legs closed, hands fidgeting in her lap.

“Uh, how do you want to do this?” I asked.

She shrugged, eyes darting to the floor. “Just… however you want, I guess. I’m already kind of, you know, ready.”

I didn’t, but I wanted to. I closed the door and leaned against it, watching her. She started to pull her shorts down, hesitated, then just shucked them and the tank top in one go, like ripping off a bandaid. She was naked, right in front of me, and more beautiful than I expected. Small, pert breasts with pink nipples, flat tummy, trimmed patch of hair above her pussy. Her legs trembled as she opened them just enough to show a flash of wet pink.

I wanted to say something, anything, but words felt stupid. Instead, I knelt in front of her and rested a hand on her knee.

She bit her lip harder. “Don’t make it weird.”

I grinned. “You’re the one who asked.”

She rolled her eyes, but her chest heaved up and down as she spread her legs wider.

I pressed the toy against her slit and watched her flinch, but not away. Her pussy was slick, and as I slid the head up and down, she let out a sound, almost a sigh, almost a moan. She was really wet, and I wondered how long she’d been thinking about this. About me doing this for her.

I eased the tip inside and she gasped, a full-body intake of breath. I watched her face, searching for signs to stop, but she just nodded.

“More,” she said, voice trembling.

I pushed the dildo deeper, hand wrapped around the shaft. My other hand steadied her thigh. She was tight. I couldn’t help but imagine what she’d look like on her back, toy buried to the hilt, face screwed up in pleasure.

“Is that good?” I asked, voice thick.

She nodded, eyes squeezed shut. “You can go harder.”

I did. Pumped it in and out, watching the way her whole body arched toward me, and how her pussy opened up to stretch around the toy. She started to rock her hips, meeting the thrusts, hands gripping the blanket.

I was painfully hard, my cock trapped under my shorts, leaking pre all over the inside. I wanted to pull it out, but this wasn’t about me. It was about Nadia, the way her back arched, the way her nipples stood up, the way she kept glancing at my face to see if I was grossed out or turned on.

I was both, and neither. I was obsessed. She was so wet, her juices leaked down from her slit. I got it all over my hand, the scent musky and sweet.

She moaned, soft and breathy at first then louder. I slid a finger down to her clit, circling gently, and she moaned.

“Oh my god,” she said, legs clamping around my wrist. “Don’t stop. Please, please don’t stop.”

I didn’t. I sped up, thrusting the toy and rubbing her clit. She was panting, sweat beading on her forehead, toes curling. She looked so innocent and so dirty at the same time, and I wanted to remember this forever.

“Can I…?” I started.

“Yeah,” she said, eyes still closed. “Anything.”

I leaned in and licked her pussy, tongue flicking the spot where my finger had just circled. She tasted sweet and clean, like skin and nothing else. She whimpered, hand going to my hair, pulling me closer. Then I pulled out the dildo, seeing her pussy gape open. Then I pushed my tongue against her pussy, moving some of the hair aside and then licked all the way up. She tasted divine and forbidden.

“Fuck, Liam. Oh my god. I’m gonna—”

I kept going, licking, pushing the dildo inside and rubbing her clit till she came. Her thighs squeezed my head, her pussy clenched around the toy, and she moaned into the crook of her elbow. I kept licking, until her hips stopped bucking and she sagged back onto the bed.

When it was over, I pulled away and sat on the floor, legs numb. My heart was racing so fast I felt sick.

She lay there, eyes glassy, chest rising and falling in shallow breaths. After a minute, she looked at me.

“Thanks,” she said, quiet.

I wiped my mouth and grinned, unable to believe any of it was real. “Anytime.”

A silence hung between us, thick and electric. She didn’t cover herself, just watched me, and I watched her. I wondered if she was going to ask for more, if this was some new normal, if things could ever go back.

They didn’t need to.

She sat up, legs crossed, and smiled for the first time all morning. “You’re such a dick,” she said again, but this time it sounded almost like a compliment.

I laughed, the tension breaking just a little. She leaned in and hugged me, naked tits pressing against my bare chest. I hugged her back.

When we finally pulled apart, she was still smiling, eyes shining with something secret.

I stood, adjusted my towel, and backed out of the room. “See you at lunch,” I said.

She didn’t answer, but the look she gave me promised this wouldn’t be the last time.
