“I saw you... in dad's office. With mom,” I said quietly. I lay across his bed, resting my chin on the back of my hands. It's been three days since I saw Nathan and my mother together. Three days since I watched them in my father's office, my mother bent over her husband's desk while her son plowed her from behind. Her fantasy come true, according to a diary she kept hidden in the attic. We'd discovered it, and was taken aback by its contents. Nathan had appeared troubled after reading it, disgusted even. But then...

“Yeah, I know.” Nathan swiveled in his computer chair to face me. He leaned against the armrest, fist pressed against his cheek. “You were peeking through the door.”

“You knew?” I asked. I didn't catch his eyes shift toward the door that night. Not once. “How did you—?”

“You left the door cracked, Rena.”

Duh. “Oh... right.” I fell silent. I wanted to say something, but the right words eluded me. I hadn't thought of what to say beyond telling him that I saw him and mom fucking. Nathan just sat there, rocking softly in his chair, as if waiting for me to say something. He seemed... fine. Unphased. I'm not sure why, but I half-expected him to be wallowing in confusion and shame, much like I had been the last few days. But he was just regular old Nate. Cool and confident.

“Why?” I asked several long moments later.

“Because,” he simply said, as if the answer was completely obvious.

“Come on, Nate, that's not an answer,” I told him. “Why? Why did you do it?”

“Because,” he said again, “because... I don't know. I just wanted her, man.”

I hopped from his bed and stood over him. He didn't look up. “You don't see anything wrong with that? You didn't feel any shame afterward?”

He snorted, looking up to me with his deep blue eyes, and said, “Do I see anything wrong with fucking my own mother? Yeah. Do I feel shame? No... not really.” We'd been talking quietly up until then, and I suddenly felt a pang of fear in my belly. Not only was it been late, Dad was back home, and I prayed to God he didn't hear Nathan just then.

“How, Nate?” I asked in a hushed tone. “What kind of sick person would—“

“Do something like that?” he finished. Impatience weighed heavy in his voice. His eyes seemed to grow darker. “In case you forgot, little sis, you watched. You watched for a long time. Probably touched yourself, too. So don't get all high and mighty with me, li'l miss hypocrite.”

I peeled my gaze away from his, his words stinging. He was right. I did watch. I watched them, and I enjoyed it. It turned me on like nothing else in the world. But unlike Nathan I couldn't shake away the shame, the guilt. Incest was wrong... plain and simple, no matter how much it aroused me. Nathan stood, his football player physique looming over me this time. He was close... real close. My nipples pressed softly against his chiseled chest, and I felt them harden like rocks. Oh, God.

“What's the matter, huh?” Nathan said, his voice hard.

With my head turned, I could feel his breath splash against my neck, and I shivered. Need pricked at my nether region. Hot, forbidden need. I tried fighting the feeling, but it was a losing battle. My body appeared to have a mind of its own. I was just there for the ride. I backed up a single step, and Nathan's hand wrapped around my tiny wrist, stopping me.

“You're turned on right now, aren't you?” he said looking down at my chest. My nipples strained through my t-shirt, beckoning him. “So what was all that talk before, Rena? Jealousy?”

Then I felt his other hand cup my pussy through my volleyball shorts, and I gasped. Lust swelled within me, urging me to give in. I fought. I tried pulling away from him, but he was stronger than me. He held me in place, his hand rubbing at my moistening slit. My shorts were getting drenched.

“Please, Nate,” I pleaded. “This is wrong... we—you can't do this...”

“Then tell me to stop,” he said.

“Nate, please!” A small voice, perhaps my conscience, screamed the words, but they couldn't make it past my lips.

Nate pushed me, and I fell back against his mattress. I tried scrambling myself together, but Nathan was too quick, too strong. He grabbed the waistline of my shorts and pulled them off, tossing them behind him.

Then he grabbed the back of my knees and pushed them back, exposing my bare, unshaven pussy that glistened with warm juices. I screamed in my mind, but my body had given in. This was wrong... but I wanted it. I wanted it bad. I wanted my brother.

“No panties, huh?” Nathan said with a wolfish smile. His mouth, kissable and perfect, hovered over my pussy as he spoke, and the heat made my clit throb. I struggled a little bit, but he easily held me there.

Then he licked me.

Firey pleasure swirled in the pit of my stomach, and then spread throughout every nerve in my body. I quivered, trying to say something but nothing coherent escaped me.

He licked me again.

I felt his tongue glide slowly from my hole to my clit. He swirled around the throbbing bud a few times before slithering that tongue back down to my needy little hole again. I thought I would lose it once he shoved his tongue inside me. I watched his head bob as he tongue fucked me, his eyes staring up at me with a sensuality that made me want him even more.

Moments later he worked his way back up to my clit, and sucked it into his mouth. I squirmed beneath him, writhing in pleasure, electricity grazing against the nerves in my thighs, my belly, and my chest.

“This is wrong,” I heard myself say in a quiet voice. “This is so bad... I'm bad. I am so—“ Pleasure shot through me like an arrow, my body quaking with an orgasm. My head fell back, eyes rolling to the back of my skull. I did my best to stay quiet, but I just couldn't. The pleasure was too great. Luckily, before I could get any louder, Nathan held his hand over my mouth, and I moaned against his palm.

“You are bad,” Nathan said. I couldn't see his face, but I just knew he was smiling, impressed with himself. I closed my eyes and tried to calm down, taking deep breaths through my nose. I'd never cum that hard in my life. My entire body was sensitive. I felt like I might die if something went anywhere near my pussy again. I had begun to wonder why Nathan's hand still covered my mouth until I heard the rustle of fabric sliding off of skin.

“Mmm!” I moaned against his hand, eyes snapping open. His cock invaded me, and I almost came again.

My pussy walls clinched around his shaft, and my body shook as though I'd been tossed in freezing weather. I looked up, watching his cock slide out of me as he slowly dragged his hips back, and back in with a quick, hard thrust that made me want to scream. God it felt good. Too good. I wondered if my mother had felt this way when Nathan was inside of her. The feeling was indescribable.

Uncovering my mouth, finally, he sat up on his knees and pulled his shirt over his head. He looked like a Michelangelo masterpiece. His football training had sculpted him to perfection. He then reached down and pulled the hem of my t-shirt over my breasts, and I suddenly felt self-conscious. My breasts weren't as big as my mother's... he probably wouldn't have as much fun with them. Or so I thought. He leaned in and wrapped his lips around one, his hand cupping the other. I gnawed my lower lip, trying not to squeal in pleasure, especially when his hips started working again, pumping his cock in and out of my sopping cunt.

“Nathan...” I murmured. He suckled hungrily at my sensitive nipples, and pleasure frayed at my nerves like fire. I tangled my fingers in his hair, holding him against my chest, silently begging him not to stop. He pounded me into another orgasm, my back arching severely. I squeaked out a moan, and I wrapped both arms around Nathan's head as my body tremored.

He continued to drill me, stroking through my orgasm. He sat up on his knees once my grip on him slackened, and let his hands take hold of my waist as he fucked me, pulling me against him. Strands of dark brown hair clung to his face with perspiration, and he was biting down on his lower lip, too. I wondered if he was close. I hoped he was. I wanted his cum, on me... in me...

Several moments later he pulled out of my pussy with a grunt, and his seed splashed warmly against my skin. Gorgeous cum covered my tits and belly, glittering prettily beneath the dull lighting of his bedroom. He looked to me with a smile, his chiseled chest heaving. I wanted to say something, but again, I couldn't find the right words to say. I just lay there, breathing ragged breaths, my hands rubbing my brother's cum into my skin.

It's still wrong, I thought.

But I love it.
