I turned my best friend’s shy, geeky little brother into my personal fuck toy for stress relief…

I wasn’t planning to sleep with anyone that night.

Okay, I *wanted* to, it had been way too long but the night was supposed to be about my best friend Ava. She’d just dumped her boyfriend (or he dumped her, whatever), so we went out to get her drunk and dancing and laughing until she forgot about him. Shots. Loud music. Sweaty bodies on the dance floor. Classic girls’ night.

By midnight Ava was finished. She was slurring, giggling, then suddenly quiet in the Uber, head against the window, completely passed out. Mission complete.

When we got back to her apartment, she flopped onto the bed like a rag doll. I pulled off her tight top her big boobs basically fell out then tugged down her shorts and panties so she’d sleep comfortably. I tucked her under a blanket. She has an amazing body, but I’ve seen it a million times. No big deal.

Now it was my turn. I stripped out of my own party clothes, grabbed her silky white robe from the hook, and didn’t bother putting underwear on. Why would I? I was just going to heat up some oven fries and chicken nuggets, eat on the couch, and crash.

Except I forgot one thing: her brother Ethan was crashing at her place too.

He’s not actually a kid he’s 20, I’m 25 but I’ve always thought of him as “Ava's little nerdy brother.” Tonight he didn’t look so little.

I walked into the living room basically naked under that short robe, and there he was: sitting on the couch, headset around his neck, game controller in his hands, TV paused on some sword-and-magic game.

“Oh crap! Hey Ethan! Forgot you were here. How you doing?”

“Uh… good. You guys just get back?”

“Yup.” I smiled. “Sorry about the outfit. If I knew you were awake I would’ve put panties on.”

He laughed, but it sounded nervous. His eyes kept dropping first to my bare legs, then higher, where the robe was slipping open just enough to show the tops of my boobs. He tried to look back at the screen, but he wasn’t fooling anyone.

I could’ve just said goodnight and left. Easy.

Instead I started thinking about sitting on his face.

And yeah, it was my fault but come on. I’d been horny for weeks. All that dancing, guys staring, bodies brushing against me, and then going home alone? My body was screaming. And now here was this shy, blushing guy who couldn’t stop sneaking looks at me. It flipped a switch.

I walked to the kitchen to make tea, letting the robe fall open a tiny bit more at the top. Not obvious, just enough so he had to imagine what my bare breasts looked like full, heavy, nipples already hard.

“You always up this late playing games?” I asked, sitting on the edge of the couch near him.

“Pretty much,” he mumbled. He was turning red.

“You’re blushing,” I teased. “Am I making you nervous?”

“I… uh…”

“Relax. It’s just me.”

But it wasn’t “just me” tonight. I was wound up, wet, and feeling kind of mean in the best way.

I put my bare feet up on the coffee table so my thighs opened a little and the robe rode up, showing the side of my ass and way too much skin.

“Tell me something,” I said softly. “Can you keep a secret from your sister?”

He swallowed hard. “Yeah… I think so.”

“Good.” I played with the edge of the robe, letting it slip open even more. My nipples were poking through the thin fabric now. “My secret is I really needed to get fucked tonight. Like, badly. Do you ever get like that, Ethan? Where you just *need* it?”

He nodded, voice small. “Yeah… sometimes.”

“Sometimes,” I repeated, smiling. “I feel like that basically every day lately. My pussy stays wet. Right now it’s so wet it’s ridiculous.”

I opened my legs just a bit more, letting him picture how slick I was between my thighs.

He made a tiny choked sound. I looked down his sweatpants were tented. He was rock hard.

“When a girl feels like this,” I said, “she should just take what she needs. Don’t you think?”

“Uh… yeah.”

“Like right now. I could just pull your dick out and ride you until I cum. Would you like that?”

“Penelope…” he whispered. “What about Ava?”

I stood up slowly. The robe fell completely open. I didn’t close it. I let him see everything my heavy breasts, soft stomach, the shiny wetness on my inner thighs.

“Lie back,” I told him.

He looked toward the bedroom door once, then back at my naked body, and did what I said.

I climbed over him, knees on either side of his head, my pussy hovering right above his mouth.

“I want your tongue,” I said. “You’re going to lick me until I cum. And you’re not stopping until I tell you.”

Then I lowered myself onto his face.

He made a surprised noise, then his tongue came out shy at first, just little licks. I wasn’t having that. I pressed down harder, grinding my clit right on his tongue.

“Like that,” I moaned. “Suck it. Use your whole mouth.”

He got the message fast. His lips wrapped around my clit and sucked first gentle, then harder when I rocked my hips and moaned louder. His hands grabbed my thighs, fingers digging in like he was holding on for dear life.

The robe slipped off my shoulders. My boobs bounced as I rode his face. I grabbed one, squeezed the nipple hard, then pushed it down to his mouth.

“Open.”

He did. I fed him my nipple and he sucked like he was starving tongue swirling, teeth grazing just enough to make me gasp. I switched to the other one while I kept grinding, smearing my wetness all over his chin and cheeks.

He was a mess already lips shiny, face flushed, glasses fogged up. His hips kept jerking up, cock begging under the sweatpants.

I reached back and squeezed him through the fabric. He groaned right into my pussy the vibration made me shake.

“You’re so fucking hard,” I whispered. “Poor baby. Been sitting here playing games while your dick was dying for this.”

He whimpered.

I slid down his body, dragging my wet pussy along his shirt, leaving a slick trail. When I got to his hips I yanked his sweatpants down. His cock sprang out thick, veiny, dripping at the tip.

I didn’t wait.

I lined him up and sank down, taking every inch in one slow slide.

We both moaned loud I slapped my hand over his mouth quick.

“Shhh,” I whispered. “Don’t wake your sister while I’m using your cock.”

He nodded, eyes wide.

I started riding him slow at first, feeling every inch stretch me, then faster, slamming down harder. My tits bounced, slapping his chest. He tried to thrust up but I pinned his wrists.

“No,” I growled. “You just lie there. This is for *me*.”

He groaned, hips twitching, helpless.

I could feel it building that tight, hot rush I’d been craving for weeks.

“Rub my clit,” I ordered, letting one hand go.

His fingers found it fast rubbing messy, desperate circles. It was perfect.

I leaned down, boobs pressed to his chest, mouth at his ear.

“Cum inside me when I say,” I breathed. “Don’t pull out. I want to feel you fill me up.”

He made a broken little sound.

I sat up, grinding deep, clit mashed against him on every stroke.

“Now,” I gasped. “Cum now, Ethan.”

He exploded.

His whole body tensed, hips bucking as he pumped into me hot, thick spurts I could feel deep inside. That pushed me over.

I came hard, slamming down one last time, pussy squeezing and pulsing around him while my legs shook and everything went white.

We stayed like that, breathing heavy, sweaty, until he started going soft inside me.

I lifted off slowly. Our mixed cum leaked out, coating his cock, his balls, the front of his pants.

I leaned down and kissed him slow, dirty, tasting myself on his lips.

“Good boy,” I whispered. “Perfect little stress toy.”

Then I stood, robe hanging open, thighs sticky, and walked to Ava's room without looking back.

“Night, Ethan.”

I heard him let out a shaky breath behind me.

I smiled as I slid into bed next to my sleeping best friend.

Night accomplished.

Twice.
