My hand was on her breast. I don’t know which of us put it there, and she was grinding her crotch into my groin. “Wrong,” I managed to gasp out.
“Take me, John-”
My fingers bit into the skin of her ass, and then she was grinding, her shorts riding up. She cried out-
“Whoa! No!” We flew apart like we’d been hit by a car and I raised my hands up above my head. “Okay, no. Whoa.”
Her lip was bleeding, and she looked at me with an expression equal parts despair and anger. And then she ran.
“Monica!” I ran after her, down the echoing alleyway, catching her only just before another set of identical and byzantine condominiums. “Hey!” I grabbed her arm and swung her around.
“I’m sorry!” she shouted. “Just fucking leave me alone!”
“Hey!” I said. “Calm down. It’s okay.”
“It is NOT okay!”
“Well-” I started. I stopped. “Well, I suppose not. But it’s fine.”
Monica brushed the hair out of her face and swallowed hard. “I didn’t mean that… what I said. I don’t want you to-”
“It’s okay.”
“I just… we were talking. I got confused.”
“Me too.”
“I want to go home now.”
So we did.
* * *
We spent most of the car ride in silence, and by the time we got home it was dark and the lights were on in the living room and kitchen, meaning mom and dad were home. Monica fled the car before I’d even pulled it into the driveway, forcing me to crank up the parking brake and fumble with the seatbelt in an effort to catch her.
I had to grab at her for the second time today in the narrow space behind her gate between our backyard and the fence. If I hadn’t, she would have jumped the backyard and been gone at Stephanie’s house for who knows how long.
“Mon,” I said gently.
“Shut-up, John!”
I swung her around into my arms, holding her by the waist until she stopped trying to squeeze out of my grip. Eventually, in exasperation, she quit struggling and collapsed against my chest. “You’re stupidly strong,” she said.
“And big. Don’t forget big.”
She groaned into my chest.
“Kid, it’s okay.”
“It’s so not okay…” Her mound of hair rolled against my chest.
I reached down and gently hooked her chin under my finger. “Listen to me-”
“Stop babying me!” she said.
“Okay,” I said, but I didn’t unhook my hands from her waist. “Don’t disappear.”
“I won’t,” she said. She looked at me and quickly glanced away. “You think I’m a freak.”
“I don’t.”
She actually pouted a little bit. “I could be a freak…”
This girl… “Whether you are or you aren’t, I’m your brother,” I said. “So I’m obligated to put up with you.”
This seemed to make some impression on her, but instead of nodding she just pulled slightly away, locking her own wrists behind my back and glancing at me sidelong. “What if you weren’t my brother?”
“But I am.”
“But if you weren’t?”
“What do you want me to say?”
She grinned sheepishly. “Do you think I’m pretty?”
“Of course.”
She bit her lip. “Do you think I’m fuckable?”
“We’re getting into freak territory now.”
She grinned madly. “Good.”
I shook my head, swinging her slightly from side to side. In our position, her waist was pinned against mine, and I could feel a warmth there…
“If we were just friends,” she said, “and I needed help, you’d help, right?”
“You’re scheming right now. I’m not hooking you up with any of my friends. I don’t want that on my conscience.”
She giggled. “I dunno. Brodie’s pretty cute.”
“Uh-huh.”
“But I don’t think he’d take care of me – like you would.”
“Yeah, well…”
Monica glanced briefly at the closed and darkened window at the side of the house, then slid closer to me, pushing her body once more into my chest. She pointed her nose up at me and spoke softer. “If we were friends…” she whispered.
“Yes.”
“But we’re more than friends.”
Tenderly, she went up on her toes and kissed my chin, her eyes never leaving mine. Damn me for a fool, but that look in her eyes was at once dear and undeniable, and I couldn’t pull away from it. We kissed, softly, secretly, on the lips. “You won’t hurt me,” she whispered into my mouth. “You won’t judge me.”
“This is a bad idea.”
She slid her hand from around my waist, took mine, and ran it up her belly and into her shirt. “You do what I want, I’ll let you do whatever you want…”
“You can find someone else-” I started, but of course I didn’t pull my hand away. Her breast, her whole body, was on fire.
“I don’t want someone else,” she said. Her voice was still a dark, hungry whisper, her eyes bright pinpoints in the dark. “Not right now. I need you inside me. Tonight.” She reached out and closed the gate behind us.
“This isn’t something that can ever be undone.” Sounds valiant, doesn’t it? But my voice was breaking and my cock was rigid. Pressed into her waist, she was well aware.
“So?” she said. “We’re related, yeah. But we’re friends. We’re adults.”
“Only legally,” I said.
She smirked. She pressed her body harder into mine. “Could you stay hard while I’m on top? While I’m using you…?”
My heart was beating so fast, if I answered it might bounce right out of my mouth. When I finally did find my voice, I said, “You’d have to be quiet…”
“I won’t wake mom and dad,” she said. There was very little of the scared little sister left in her now. Her voice was devious, excited. “Besides, that’s part of the fantasy, right? I don’t want to wake you either.”
We broke apart, sliding softly from each other’s hands. “Am I doing this just because you’re too horny to leave the house?” I asked.
“You’re doing this because you want to fuck me, too,” she said. “Admit it.”
My cock was straining inside my pants. And she was right. I wanted to fuck her right there, against the house. The look in her eye, I think she’d only be too happy to oblige. “And this…” I said instead. “After this, what?”
“What do you think?” she said. “It’d be an awfully long summer if you didn’t let me try out… some other things.”
“You don’t even know if you’ll like it.”
“Oh, big brother…” When she said it, it sent a chill down my spine. She wiggled her hips a little, coming closer, smiling. “If I don’t like it,” she slid down on her knees, “you can just make me like it…”
I didn’t even try to stop her. I just watched her fingers work the button of my jeans, the zipper. I looked up once, behind us at the dark neighbor’s house. Again at our darkened window. I felt the cool rush of the night air hit my naked cock, and my sister’s gasp. “BIG brother,” she murmured. And then I looked down and my sister was putting her mouth on my cock.
“Ah, Moni…”
She slid it over her tongue without hesitation. I groaned as she took inch after inch, deeper. It was too much to bear, and I leaned up against the house, my hand keeping me standing, and by reflex pushed my hips forward.
“Mm-mm,” my sister moaned under me. She let me thrust again, into her mouth.
My other hand rested on her blonde head as I thrust my hips forward to fuck my sister’s mouth. “Anytime,” she gasped, pulling her lips away and using her hand to stroke me (the fingers barely reached around my shaft). “Anytime you want my mouth, Johnny. Your little sister…” She swallowed me. Spat on it. “I’ll take care of you.”
“You are a little slut,” I groaned.
That pleased her. She moaned into my cock. “Your slut,” she gasped, her voice thick with the spit and cum that coated her throat.
“We should go,” I groaned, planting both hands atop her hand and sliding myself back through her lips anyway.
“Mm-hmmm,” she moaned, staring up at me. It was too much to take. That morning I’d been staring at her giggling as she showed me her tit. Tonight, here we were, my pants around my ankles in our backyard and she on her knees, letting me feed her my cock.
“You’re big, Johnny. So big.” She held it in her hands, as if measuring it. “You’re going to have to help me get it inside.”
