The next morning

You blink your eyes open, groggy from a night filled with erotic dreams that seemed all too real. The sunlight streaming through the window casts an almost ethereal glow over the room, making you feel like you're still in the midst of those hazy, lust-filled fantasies. And like every morning your cock is hard, but this morning it's harder... and bigger. You'd swear even at your hardest (last night, even), it had never been this thick or long before.

Your mind races with questions about what happened last night and the newfound powers you seem to possess, but more than anything you craved sex. Somehow you knew, jerking off wouldn't help your situation. The demon, Eve, had awakened something inside you, something primal and uncontrollable - an insatiable hunger for sex that threatens to consume everything in its path.

With a sense of purpose, you push yourself out of bed and head downstairs, hoping to find someone – anyone – who can help sate your needs. Well, almost anyone you think, when you see your best friend and roommate, Blaine's little sister, Madison, sitting at the table, her eyes buried in a book. Shit. You had forgotten she was staying here this weekend.

You can't help but stare at Madison. Long gone are the days of her annoying you guys at sleepovers. Her blonde hair is messy this morning, but frames her delicate features and blue eyes perfectly. She's young, only recently graduated—fertile—the thought intrusively creeps into your head.

But it's her body that truly captivates you – she is stacked. Her white t-shirt and the lacy black bra beneath are doing little to contain her massive tits. The fabric clings to her skin, offering just enough resistance for your mind to imagine how those firm mounds would feel against your palms.

As Madison looks up and sees you in nothing but your boxer briefs, straining ridiculously against the fabric she neither blinks nor shows any hint of surprise or discomfort in her eyes. Instead, her gaze lingers on your erection with what seems like curiosity rather than shock.

"Morning, Clay" she greets you cheerily. "Blaine already left for the gym. Sleeping in?" There's an unspoken question in her words as she casually glances at your hard-on again before taking a sip from her coffee.

You're momentarily taken aback by her relaxed demeanor towards your blatant arousal, but that quickly turns into understanding. This must be part of your new powers.

"Oh yeah, umm... late night," you reply. With renewed determination, you take a deep breath and make up your mind. She's off-limits, of course, you wouldn't do that to Blaine. Besides, how could you even know she wants this?

"Sure, sure. So umm, Clay are you going to let me take care of that for you?" Madison asks, gesturing to your cock, as if in answer to your internal debate.

Your mind races between reason and desire, but the latter wins out as she continues to stare at your cock with a curious expression.

"No wait," you say, trying to sound firm enough to resist temptation yet soft so as not to offend. "I can't.. Blaine would..."

Her eyes glint mischievously, catching sunlight. "Oh come on, Clay. You'd be doing me a favor. I need to taste that beautiful cock." She gives a playful smile and makes her way over to you.

"I can see that you really need this," she continues, looking straight into your eyes, as she reaches into your underwear and retrieves your cock.

"Please, Clay let me help you out," she urges gently, and your resistance melts away.

Madison pushes you back into a kitchen chair and lowers herself on her knees beneath you, before grabbing your cock with one hand wrapping her plump lips around your girth.

The feel of her warm, wet mouth enveloping your cock is nothing short of mind-blowing. There's none of the charged energy that you noticed with Eve, just pure unadulterated pleasure.

She slides down onto it with an expert finesse that tells you this isn't her first time. Her tongue swirls around the head, teasing every sensitive spot as if she's trying to savor each inch of you.

You can feel every nerve ending on your cock pulsating wildly in her mouth as she bobs up and down, taking more of it inside her throat. Her cheeks hollow out with every stroke; this girl clearly knows how to suck dick.

"Mmm... Clay, you taste so good," she moans appreciatively around your hard member, drawing another groan from deep within you.

As she continues her relentless oral **** on your cock, you're torn between wanting this to last forever and needing release now. You wrap one hand in her hair, guiding her pace while keeping yourself in check.

"Oh shit... Madison... I'm gonna cum..." The words barely escape as her lips finally reach the base of your cock, sucking it deep into her throat.

Her eyes meet yours and she gives a subtle nod, understanding the urgency written all over you.

That small signal is all you need, as you unload spurt after spurt of hot cum into her throat. As you slide out from her mouth, she does **** and gag, but to her credit, she doesn't let a single drop spill.

As you catch your breath, Madison wipes the corner of her mouth with one delicate finger and then licks it clean.

"Thank you for letting me do that. You won't regret it," she whispers sincerely as she looks up at you through watering eyes.

"I promise I won't tell anyone unless you want me to," she adds in a softer tone, almost shyly.

Her words make something inside you twist and turn uncomfortably. You shouldn't have done that. But she did clearly enjoy it. And you were in near physical pain from horniness, even though you had just gotten your brains fucked out the night before.

There was a lot you needed to figure out about your new condition. But for now, you need to get yourself cleaned up before Blaine gets back.
