Mark’s eyes skidded to a halt on the golden goddess, and his eyebrows rose. Then, he turned slowly back to me.

“You sure?”

“Yeah,” I grunted over the music, my frustration building. “Why? I thought you said you knew everyone here.”

“Yeah, mostly,” my friend drawled, his brows still at the level of his hairline. “But I think you should relax first. I mean, you’re real strung-out and the hospital’s been playing mind games–”

“What the fuck is your problem?” I growled, my hands gripping into fists at my side. “Just introduce me.”

Mark hesitated a moment, but then he shrugged.

“Sure, no prob.” My buddy led me through the crowd to where the beautiful girl was talking to some idiot with acne and halitosis. What the fuck? Do people not use mouthwash anymore?

“Yo Sven, yo Kristie. Have you met Nick? My bro here—”

The blonde turned to face me and smiled angelically. My cock surged again because she was every bit as beautiful up close as from afar. Her blue eyes were large and limpid like the still waters of a clear pond, and her tip-tilted nose was delicate and feminine, forming a perfect ski slope. But to my surprise,shedidn’t look surprised to seeme.

“Hi Nick,” the curvy girl murmured. “I didn’t know you were home.”

That’s when my heart skidded to a halt because what the fuckity fuck?

It’s my stepsister, Kristie.

The one whose mom was married to my dad.

My heart pumped and I stared like a fucking moron at the beautiful woman. What the hell? When the fuck did Kristiedevelop tits and an ass? When did she fill out so that her big breasts push at the soft wool of her sweater, her jeans hugging the delicious roundness of her rear end? When did she develop the features of an angel, complete with innocent blue eyes and a feminine, yet determined chin?

The last I remember was a child with bony knees, a haunted expression on her face, and her hair in pigtails. Hell, was her hair even blonde back then? I hate to say it, but I can’t be sure because the transformation was so absolute. But it’s the way she laughs, the mischievous look in those blue eyes, as well as the warmth and welcome radiating from her gaze. Bells suddenly clang in my head with alarm.

“Nick?” she murmured playfully. “Are you there? Earth to Nick, Earth to Nick. I think medical school might have put him into a catatonic state.”

I snap out of my shock, springing back to life.

“Oh yeah, hey, what’s up?” I manage in a gravelly voice. Of course, Mark’s smirking at me like a fucking douche. “I’m going to grab a beer. Anyone else want one?” Then without waiting for an answer, I stepped away abruptly, heading into the kitchen to calm the fuck down.

My heart pounded, the air in my lungs growing tight.

That was Kristie? Was I lusting after my own stepsister?

I yanked open the fridge, trying to process the realization, but even the arctic blast from the ice box didn’t help. What the fuck just happened? How did Kristie the child-waif become Kristie the seductress? Yet I could still see the tempting curve of her ass before me, not to mention those big breasts and pouty lips. I wanted to charge her and tackle her to the ground, beforecovering that soft body with my big one and driving my cock into her tight snatch. She’d be wet, willing, and ... holy fuck.What if she’s a virgin?

That’s when I started doing mental gymnastics. My mind whirred as I computed birth dates. I knew Kristie was a year older than my biological sister, Milly, which made the young woman ... seventeen.Tooyoung. Even I can’t go there because with a medical license on the line, I can’t afford any infractions of the law. My stepsister is one hundred percent off limits, even if she has the figure of Jessica Rabbit and the allure of Marilyn Monroe.

Needless to say, I left the party without another word. I stalked into the cold winter night, my mind warring with the needs of my cock. I wanted into the plush blonde, but the problem is thatshe’s my underage stepsister.Was I really going to go there? Hell no. I may be a depraved motherfucker, but even I can’t risk that kind of danger.

As a result, I did my best to banish thoughts of Kristie from my mind. My vacation was obviously toast, and I went back to the hospital, burn out be damned. Yet the beautiful blonde continued to dance before me in my mind, and I jerked off to her at every opportunity possible: in the shower, in the restroom at the hospital, and even in my car. My hand got a good workout as the voluptuous teen spread her legs in my imagination, cupping those big breasts in welcome. Kristie, moaning my name as I penetrated her tight, juicy pussy. Kristie, gasping with pleasure as I suckled at her massive tits. Kristie, her belly soft and full, pregnant with my child, as I filled her with another baby ... and then another ... and then another.

What the fuck?My fantasies reached incredible heights, and it was a fucking disaster. Sure, I’ve fucked a lot of women in mylife but never had I become obsessed with a woman whom I’ve never even touched. I’ve never kissed those soft lips, much less caressed her tender breasts. I’ve never slipped my cock into her tight cunt in the deep of the night, making her moan with pleasure while begging for more. So where the fuck was this going? I was utterly consumed by a seventeen-year-old girl ... and yet Kristie was a hundred percent off limits.

Kristie

Ilook around the restaurant and try to smile like I’m happy because Iamhappy. My younger sister is getting married, and this is the rehearsal dinner before Milly’s wedding tomorrow. Everyone’s dressed to the nines, and I’ve done my part too. My blonde hair cascades down my back in soft waves, and I’m wearing a pretty pink gown that highlights my big bust and narrow waist without being vulgar. The fabric skims my curves, rather than clinging like Saran wrap, and I’ve topped the outfit off with pink high heels and a silver clutch.

“Darlin’, are you okay?” my dad asks. I call Steve “Dad” because after years of hearing Milly and Nick call him Dad, I fell in line too. Plus, the older man’s always been generous, and treated me like a real daughter even though he didn’t have to. Again, Steve let me stay at his house after my mom died, and I’ll always be grateful for that kindness. I was a young girl with nowhere to go,having just lost her only parent, so the older man’s gesture was a lifesaver.

But Steve has also caused problems for me in the past, and in fact, he’s causing problems even now. We’re seated next to each other at one of the main tables as Milly and her fiancé work the room. The wedding couple look happy and content, Milly gorgeous in a yellow tulle dress and her fiancé handsome, if a bit short, in a navy tux.
