Chapter 2: Indelible Blue

Incest Sex Story: Chapter 2: Indelible Blue - Noah was just trying to survive high school, keep his head down, and definitely not think about his gorgeous, off-limits twin sister. But after an April Fool’s prank leaves him with a very blue—and very visible—erection, Lena starts looking at him like he’s more than just her awkward brother.

Ten minutes later, Noah was furiously scrubbing at his cock, glaring at himself in the mirror like sheer force of will could erase this stain.

But no matter how much soap he used, no matter how hard he scrubbed (and yeah, that was a nightmare in itself), it wasn’t coming clean.

“Fucking hell,” he muttered under his breath, gripping the edge of the sink.

There was only one option left—he’d have to tell Mom. Maybe she could take him to the hospital. It would be mortifying, and she would probably want to know how his sister had gotten the dye onto his dick. But he would just have to tell her the truth.

This was bad. This was so much worse than a few pink streaks through his sister’s hair.

And then—the worst thing imaginable happened. The bathroom door swung open, and his sister stepped inside.

Noah jerked, instinctively twisting to block himself with the sink, legs locked together, face flushed. His robe was still on the floor behind him, and he wasn’t about to scramble for it now.

Their eyes met in the mirror.

Lena closed the door behind her, looking way too smug, her blue eyes dancing with amusement.

She was wearing a pale blue cami and matching sleep shorts, both barely-there and clinging to her like a second skin. Her blonde hair was tousled from sleep, lips full and pink, cheeks slightly flushed.

She crossed her arms beneath her breasts, pushing them up. Her nipples pressed against the fabric. She smiled sweetly. “Having a little trouble there, baby bro?”

He ground his teeth, glaring at her. “Get out!”

“No way,” she laughed. “This is way too good.”

“I can’t believe you’re enjoying this.”

“Come on, Noah. Let me see my masterpiece.”

He shook his head. “No. Go away!”

She tilted her head and walked closer, slowly, like she was approaching a skittish animal. “It can’t be that bad.”

“Yeah, well, it is.”

Noah kept his gaze locked on the mirror, his crotch still firmly pressed against the sink.

She went up on her tip-toes, propping her chin on Noah’s shoulder so she could look down the front of his body.

He kept himself perfectly still, his lower half hidden behind the sink, but his arms and legs trembled. He could feel her soft, warm breath caress the bare skin of his neck, and goosebumps prickled along his arms.

He was suddenly very aware that he was naked and his sister was barely dressed.

She stared down at where his dick was hiding. “Come on,” she said. “Let the little guy out. I promise not to laugh.”

“No!”

He couldn’t help his eyes from flicking toward her breasts, the creamy mounds almost spilling out of her top. Her nipples were pebbled, the tips dark shadows visible beneath the flimsy camisole.

Lena rolled her eyes and tried to pull him back from the sink, but he held his ground. She was tall, but he was taller. And he’d filled out a lot in the last year.

“Leave me the fuck alone, Lena!”

Her voice dropped. “Noah, let me see.”

His name was soft on her lips, and something inside him trembled. He hated her for this, and yet, he wanted her. Wanted her badly. He was all too aware of his nudity, and the softness of her hip where it pressed against his upper thigh.

They’d taken baths together when they were little, but that had been different. That had been innocent. Now, there was nothing innocent about the way he craved her.

“You’ve actually got a nice ass,” she said quietly, her breath warm against his neck.

He flinched.

“That’s not helping.”

“But it’s true.” She was leaning into him now, her breasts pressing into his bicep as she tried to shoulder him away from the sink. Her fingers traced lightly over the back of his neck. “I’ve seen how you perv on me and my friends when we’re out by the pool.”

Noah swallowed thickly. His new obsession with his twin sister had not gone unnoticed. Lena had even called him out on it a few months ago. Fortunately, she’d never responded with anger, just amusement and teasing that sometimes bordered on cruelty.

The situation had made him miserable. He was sick and disgusting. He knew that. But that awareness didn’t diminish the ache he felt for her.

Lena pressed a soft, decidedly non-sisterly kiss to the back of his neck. “Just let me see, Noah. Please. I’m sorry.”

His eyes flicked up to the mirror. He saw his own lust, and her twisted delight. He grunted.

“I hate you,” he said.

“No, you don’t,” she replied. “You love me.”

He squeezed his eyes shut and slowly shook his head.

She pressed her lips to his bare shoulder, and his cock gave a painful throb. “Please,” she said. “Let me see. I’ll make it better, I promise.” Lena’s discovery of his crush, and her subsequent rejection, had not stopped him from hoping, even as she’d delighted in using it to torture him.

“Such a reckless, little pervert,” she teased, smiling sweetly as she caught his eyes move from hers to the gentle swell of her breasts. “It’s no wonder you stick your filthy little thing in any hole you can find.”

He flinched.

“Should I be jealous?” She leaned close, whispering in his ear. “Or does my little brother think about me when he fucks his fake pussy? Do you pretend it’s mine?”

His throat tightened. “You’re being mean.”

“Am I?” She laughed. “I’m just asking questions.”

“I hate you,” he repeated.

She pressed a kiss to his temple, and it sent shivers down his spine.

“Do you want me to fuck you, baby bro?” she murmured, her voice soft. “Would that make you feel better?”

Noah’s cheeks flushed crimson, and his cock throbbed. “It’s not like you can help it,” she continued. “You’re just a disgusting little pervert.”

Noah swallowed hard. His entire body felt like it was on fire.

“And of course you really should delete your internet history more often,” she murmured. “Quite a shock learning that you’re baby bro is into incest porn?”

Noah’s throat clicked. His cheeks burned. He’d only looked it up because—

“You’re a little freak, Noah.”

Yeah, that was the reason.

“Go away,” he mumbled.

“Let me see your little dick, and I will.” She leaned in so that her cheek rested against his. “Please, baby brother, show me your cock?”

“Don’t call me that,” he snapped.

“Why not? I’m five minutes older than you. Isn’t that what you want, Noah? For your big sister to take care of you?”

“God, Lena!”

“It’s okay,” she said. “I’m not judging. I mean, I’m never going to touch your cock—”

Noah flinched.

“But I can still be a good big sister and help you out.”

“Lena, please.”

“Let me see it, and I’ll set you up with one of my friends.”

Noah closed his eyes as her lips brushed the shell of his ear. “Of course, the blue cock might be a dealbreaker. Most girls I know aren’t into fucking smurfs.”

“Why are you being such a bitch?” he asked, his voice cracking.

Lena nipped his earlobe, and Noah jumped. She laughed softly, and the sound sent a shiver down his spine. “Oh, come on, baby brother. I’m only a bitch because you’re always such a little shit.” He saw her lips curl into a smile. “Now show me that blueberry cock and we’ll be even for last year.”

Noah refused to pull away from the sink, but he did shift his body slightly, his arm brushing against her, scraping the stiff peak of a nipple.

Lena made a low noise in the back of her throat, and he flinched. The head of his cock, swollen and leaking precum, popped into view.

“Oh shit, it really is blue.” She sounded pleased.

“Yeah, thanks, Lena. I’d figured that out myself.”
