Chapter 1: Waking Up Blue
Incest Sex Story: Chapter 1: Waking Up 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.

Noah woke up hard, which wasn’t unusual. What was unusual was the deeply alarming, electric blue color currently staining the entire length of his erection.
For a full ten seconds, he just stared at it, mouth ajar, brain struggling to boot up.
What the—?
Then panic kicked in like a wrecking ball. He shoved off the blankets, sat bolt upright, and grabbed his cock with both hands like he could physically peel the color off.
What the actual fuck is happening?
His first thought was some kind of medical emergency. Maybe he’d cut off circulation? Perhaps he was dying, or this was some bizarre, sex-related karma for all the very inappropriate thoughts he’d had about his sister, Lena—
Oh god. Lena!
Like a sledgehammer to the chest, realization struck him. Today was April 1st.
Last year’s prank came rushing back. He’d added pink hair dye to his sister’s shampoo. She’d chased him half-naked around the house, dripping wet and murderously furious. Only Mom’s intervention had saved him from death by towel strangulation.
Lena had not been amused by his prank.
But for Noah, it had been the highlight of his year, watching his beautiful twin sister tear after him in nothing but a towel, rivulets of water sluicing down her pale, smooth skin as she threatened to end him. He could still picture her pale thighs and the dangerous bounce of her breasts as she chased him. The memory lit a fire low in his stomach.
Now, staring at his throbbing, blue cock, Noah realized exactly who had struck back. A sick, twisted part of him hoped she’d snuck into his room and applied the dye to his cock while he slept. The idea of her pretty fingers touching his penis...
Noah swallowed hard.
It was unlikely she’d been so hands-on, but he knew this had to be her.
He grabbed his phone off the nightstand and fired off a message, nearly knocking over his lamp in the process.
Noah: Tell me you didn’t.
A chime echoed from the room next door. Seconds later:
Lena: Didn’t what? [Innocent Halo Emoji]
Noah: Lena.
Lena: I’m gonna need you to be more specific. [Smirking Face Emoji]
Noah: Why is my dick blue?
A pause.
Then, from beyond the wall, he heard laughter cackle—bright, gleeful, unmistakably his twins.
Lena: It worked
Noah: LENA!
Her answer came almost instantly.
Lena: Happy April Fools, dumbass. [Winky Face Emoji]
Noah: I can’t believe you.
Lena: [Laughing Crying Emoji]
Noah: What the fuck am I supposed to do with a blue dick?
Lena: I don’t know. It’s not like you’ve ever used it before. [Shrugging Emoji]
Noah: That’s not true.
Lena: I mean, unless you count all those long showers you take after I walk around in a tank top. [Smug Face Emoji]
Noah: That’s not—
Lena: You’re not exactly subtle, Noah. You practically eye-fuck me when you think I’m not looking. [Devilish Grin Emoji]
He scowled at the screen, but his very-not-helpful dick twitched again.
Lena: Remember Christmas Eve? When I bent over in those leggings and you sprinted out of the room? [Laughing Crying Emoji]
Noah: You did that on purpose?
Lena: Maybe I did. [Winky Face Emoji]
Lena: You were so red, I thought you were gonna pass out. [Heart Eyes Emoji]
He didn’t respond. Because it was true.
Lena: Anyway. I noticed you weren’t hiding her too well either. [Side Eye Emoji]
Noah: Who?
Lena: Your little silicone sweetheart. [Kissy Face Emoji]
Noah’s blood ran cold.
He yanked open his nightstand drawer. The flesh-colored silicone sex toy sat tucked in the back. Noah’s pocket pussy. He’d bought it a few months ago, and it had become a guilty obsession. Its opening was unmistakably stained a now familiar blue.
Lena: I’ll bet your cock matches the inside of your little plastic girlfriend. [Grinning Devil Emoji]
He wanted to melt into the bed.
Noah: You. Went. Through. My. Stuff.
Lena: Not my fault you’re terrible at hiding things. [Eye Roll Emoji]
Noah: God, Lena, I can’t believe you’d do this.
Lena: It wasn’t easy. I wore three pairs of gloves to avoid dyeing my fingers or accidentally touching one of your loads. [Vomiting Face Emoji]
Noah: Jesus, you’re disgusting.
Lena: Says the boy with a cum-filled hunk of rubber in his nightstand. [Smug Smirk Emoji]
Noah: Please stop talking.
Lena: You do know you can wash the jizz out, right?
Noah groaned and threw an arm over his eyes. He did wash it out. Just ... not always immediately. He got tired.
Lena: You should be grateful I didn’t tell Mom that her baby boy keeps a fake vagina in his nightstand. She would’ve freaked.
Noah: You wouldn’t.
