The Panty Thief

My sister Sarah is 24. She’s been with Tom for about three years now. He’s 27, tall, dark hair, works as a personal trainer. Built like a fucking Greek statue. I’ve lived with them for the past six months while I save up for my own place.

I’ve always noticed Tom. Hard not to. The way his shirts stretch across his chest. The way his arms look when he’s carrying groceries. The way his sweatpants hang low in the morning. I’d catch myself staring and feel guilty. He’s my sister’s boyfriend. Off limits.

But my body didn’t get the memo.

Last Thursday, Sarah had a late shift at the hospital. She’s a nurse. Left around 7pm, said she wouldn’t be back until midnight. Tom was home. I was in my room scrolling through my phone when I realized I left my laundry in the bathroom.

I walked down the hall. The bathroom door was slightly cracked. I heard something. A sound. Rhythmic. Soft grunts.

I should’ve walked away. I know that. But I didn’t. I peeked through the crack.

And there he was. Tom. Standing in front of the bathroom counter. His sweatpants around his ankles. His hand wrapped around his cock. Stroking. Fast. His other hand held something.

My panties.

The pink lace ones I’d left in the laundry basket. The ones I’d worn the night before. He was holding them against his face. Smelling them. Jerking off with them pressed against his nose.

I couldn’t breathe. Couldn’t move. I just watched.

His hand moved faster. His hips bucked. His face was twisted in pleasure. He brought my panties down to his cock. Wrapped them around himself. Stroked through the lace.

“Oh fuck,” he whispered. “Fuck yes.”

I should’ve run. Should’ve screamed. Should’ve done anything but stand there watching my sister’s boyfriend get off on my underwear.

But I was frozen. And wet. So fucking wet.

He came. All over my panties. White and thick. He kept stroking through it. Moaning. Then he looked up. Straight at the door. Straight at me.

Our eyes met.

“Fuck,” he breathed.

I pushed the door open. Didn’t even think. Just walked in. “Tom,” I said. My voice was shaking. “What the fuck?”

He panicked. Dropped my panties. Tried to cover himself. His cock was still hard. Still wet. Pre cum dripping down the shaft.

“I’m sorry,” he said. “I’m so fucking sorry. I don’t know what came over me. I just—I found them in the laundry and I couldn’t—fuck. I’m so sorry.”

“Those are mine,” I said. Stepped closer. “My panties.”

“I know. I know. I’m disgusting. I’m so sorry.”

“Did you smell them?” I asked.

He froze. “What?”

“Did you smell them before you came on them?”

He swallowed. Nodded. “Yeah. I did. They smell like you. Sweet. Like vanilla and—fuck I’m so sorry. I’m the worst person.”

I was standing right in front of him now. Close enough to see his cock twitch. Close enough to see the guilt and shame and something else in his eyes.

“Show me,” I said.

“What?”

“Show me how you did it.”

He stared at me. His mouth open. “I don’t understand.”

“You owe me,” I said. “You used my underwear to jerk off. The least you can do is show me.”

He hesitated. Then he picked up my wet panties. Wrapped them around his cock again. Started stroking. Slow at first. Then faster. His eyes locked on mine.

“Fuck,” he breathed. “You’re not mad?”

“I’m fucking furious,” I said. “But I’m also turned on. And I don’t know how to process that.”

He moaned. His hand moved faster. “You’re so beautiful,” he said. “I’ve wanted you for months. Every time I see you in those shorts. Every time you walk past me. I can’t stop thinking about you.”

“Then stop thinking,” I said. “Fuck me.”

He dropped my panties. Grabbed me. Pulled me against him. His lips crashed into mine. Hard. Desperate. His tongue pushed into my mouth and I tasted myself on him. Sweet and salty.

He pulled back. Looked at me. “Are you sure?”

“Yes. Fuck yes. I’ve never been more sure of anything.”

He kissed me again. His hands were everywhere. On my tits. My ass. My waist. He lifted me onto the bathroom counter. Pushed my shorts down. My panties were soaked. Dripping.

“Fuck,” he breathed. “You’re so wet.”

“Watching you jerk off on my panties did that,” I said. “Now fucking do something about it.”

He dropped to his knees. Put his mouth on me. His tongue found my clit. Licked. Sucked. His fingers pushed inside me. Curling up. Hitting that spot.

“Oh my god,” I moaned. “Tom. Fuck. Don’t stop.”

He didn’t. His tongue moved faster. His fingers curled deeper. I grabbed his hair. Pulled him closer. Grinded against his face.

“I’m close,” I warned. “I’m gonna cum.”

“Cum for me,” he said. “Cum all over my face.”

I did. Screaming. Gushing. He kept licking through it. Swallowed everything. Didn’t stop until I was shaking.

He stood up. His cock was still hard. Pre cum dripping down the shaft.

“Bend over,” he commanded.

I turned around. Bent over the sink. Looked at myself in the mirror. My face flushed. My hair a mess. Behind me, Tom was lining himself up. His hand gripped my hip.

“Tell me you want this,” he said.

“I want this. I want you inside me.”

He pushed inside me in one slow motion. Inch by inch. I screamed. He was so thick. So deep. Stretched me open.

“Fuck,” I breathed. “You’re so big.”

“Look at yourself,” he said. “Look at how beautiful you look taking my cock.”

I watched in the mirror. Watched his hips move. Watched his cock slide in and out of me. Watched his abs flex with every thrust.

“Harder,” I begged. “Fuck me harder.”

He did. Pounding into me. His hand on the back of my neck. Pushing me down against the sink. The other hand reached around and found my clit.

“You’re so tight,” he grunted. “So fucking tight.”

“Don’t stop,” I begged. “Please don’t stop.”

He fucked me faster. Deeper. His thumb circled my clit. I was already close again. So close.

“I’m gonna cum,” I warned.

“Cum on my cock,” he ordered. “Cum all over it.”

I did. Gushing. My legs shook. I almost collapsed. He held me up. Kept fucking me through it.

He pulled out suddenly. Turned me around. Pushed me to my knees.

“Open your mouth,” he said.

I did. He pushed his cock into my mouth. I tasted myself on him. Tasted us. He grabbed my hair and fucked my throat.

“I’m gonna cum,” he warned. “Swallow it. All of it.”

I looked up at him. Nodded as much as I could with his cock down my throat.

He came. Hot and thick. So much of it. I swallowed. Kept swallowing. Tasted him. Tasted us.

He pulled out. I opened my mouth. Showed him I’d swallowed everything.

“Good girl,” he breathed.

He pulled me up. Kissed me. Soft this time. Lingering.

“I’m sorry,” he said. “For the panties thing.”

“Don’t be,” I said. “Best thing that’s ever happened to me.”

He laughed. Then his eyes got dark again. “We’re not done.”

“Good,” I said. “Because I’m not done either.”

He pulled me into the shower. Turned on the water. Pushed me against the tile. Fucked me again. From behind. His hand on my throat. The water running down both of us.

“You’re mine now,” he growled in my ear. “You hear me?”

“Yours,” I breathed. “I’m yours.”

He came inside me. Filled me up. I felt it dripping down my thigh. Mixed with the water.

We showered together. Cleaned each other up. Kissed under the water. Soft and slow.

When we got out, he wrapped me in a towel. Carried me to his bedroom. Laid me down on the bed.

“You’re still hard,” I noticed.

“Always am around you,” he said.

He fucked me two more times that night. Slow and deep. Then fast and rough. Every position. My legs wrapped around his waist. My face in the pillow. Me on top.

At midnight, Sarah came home. I was back in my room. Wet. Sore. Still full of him.

She kissed him goodnight. Went to bed.

Tom looked at me across the room. Winked.

I went to my room. Touched myself thinking about it. Fell asleep smiling.

He’s been different since then. More attentive. More touchy. Sarah doesn’t notice. Or maybe she does and doesn’t care.

Last night he whispered to me at dinner. “Found another pair of your panties.”

“You’re disgusting,” I whispered back.

“You love it.”

He’s right. I do.

I’m wearing those panties right now. Thinking about him finding them again. Thinking about what he’ll do when he does.

My sister’s boyfriend. My secret. My addiction.

I can’t stop. And I don’t want to.
