STORY TITLE: BEST FRIEND’S SISTER CHAPTER 1

Jamie

Jamie’s palms were already sweaty as she stepped onto the crowded rooftop.

The party was loud — bass-heavy music vibrating through the wooden deck, fairy lights twinkling against the London night sky, and the distant hum of the city below. She had let her best friend Maya drag her here, promising it would be “good for her” to get out more. What Maya didn’t know was that Jamie had only agreed because she heard Lena might show up.

Lena. Maya’s older sister.

The one woman Jamie had been secretly craving for three long years.

At twenty, Jamie still felt inexperienced compared to most of her friends. She had kissed a few girls at university parties, but nothing serious. Nothing that made her body burn the way just *thinking* about Lena did.

And there she was.

Lena stood near the railing, a glass of red wine in her hand, looking like sin wrapped in designer clothes. Her black crop top clung to her full breasts and toned stomach, while tight jeans hugged her hips and long legs. Her dark wavy hair cascaded over one shoulder, and her sharp eyes scanned the crowd with bored confidence — until they landed on Jamie.

A slow, dangerous smile spread across Lena’s lips.

Jamie’s heart slammed against her ribs. She tried to look away, but it was too late. Lena was already walking toward her, hips swaying with every step.

“Well, well,” Lena purred when she was close enough for Jamie to smell her perfume — something warm and spicy. “If it isn’t my little sister’s favorite girl. Jamie.”

“Hey, Lena,” Jamie replied, trying to sound casual. Her voice came out breathier than she intended.

Lena’s gaze dragged slowly down Jamie’s body — over the tight little black dress she’d worn, the way it hugged her curves, then back up to her flushed face.

“You look… grown up,” Lena said, voice low. “When did that happen?”

Jamie swallowed hard. “I’m twenty now.”

“I know exactly how old you are.” Lena stepped closer, invading Jamie’s space. The heat from her body made Jamie’s nipples tighten against the thin fabric of her dress. “I’ve been keeping count.”

The air between them felt electric. Around them, people laughed and danced, completely unaware of the tension crackling in their little corner of the rooftop.

“Where’s Maya?” Lena asked, eyes never leaving Jamie’s mouth.

“Downstairs. Making out with some guy she just met.”

Lena let out a soft, wicked laugh. “Good. That means she’s distracted.” She reached out and brushed a strand of hair behind Jamie’s ear, her fingers lingering on the sensitive skin of her neck. “I’ve been watching you tonight, you know.”

Jamie’s breath hitched. “You have?”

“Mmm. You’ve been avoiding looking at me… but your body keeps turning toward me. Like you can’t help it.” Lena’s thumb traced Jamie’s jawline. “Tell me something, baby. How long have you wanted me to fuck you?”

Jamie’s knees nearly buckled at the blunt words. Heat flooded between her thighs.

“I… Lena, we can’t,” she whispered, even as her body leaned closer. “You’re Maya’s sister.”

Lena’s eyes darkened with lust. “That’s exactly why we *should*.” She leaned in until her lips brushed Jamie’s ear. “I’ve seen the way you look at me during family dinners. The way you squeeze your thighs together when I wear short dresses. You’ve been fantasizing about me for years, haven’t you?”

Jamie couldn’t deny it. Her face burned with shame and arousal.

“Yes,” she admitted in a shaky whisper.

Lena hummed in satisfaction. “Good girl. I like honesty.” Her hand slid down to Jamie’s waist, gripping her possessively. “Come with me.”

She didn’t wait for an answer. Lena took Jamie’s hand and led her through the crowd toward the quieter side of the rooftop, where tall plants created semi-private corners. Jamie’s heart raced as she followed, knowing she should pull away but completely unable to.

When they reached a shadowed spot, Lena pushed Jamie gently but firmly against the wall, caging her in with her taller body.

“You’re shaking,” Lena observed, a pleased smirk on her lips. “Are you nervous, baby?”

“A little,” Jamie confessed.

Lena’s hand came up to cup Jamie’s face. “You don’t need to be nervous with me. I’m going to take care of you tonight.” Her thumb stroked Jamie’s lower lip. “But I am going to be in control. Do you understand?”

Jamie nodded quickly, already feeling herself getting wet.

“Use your words,” Lena commanded softly.

“Yes… I understand.”

Lena’s smile was pure sin. “Good girl.”

Then she kissed her.

The kiss wasn’t gentle. It was hungry, demanding, and full of years of pent-up tension. Lena’s tongue swept into Jamie’s mouth, claiming her completely. Jamie moaned into the kiss, her hands fisting in Lena’s top. Lena pressed her thigh between Jamie’s legs, applying delicious pressure right where she needed it.

When Lena finally pulled back, both of them were breathing hard.

“Look at you,” Lena murmured, eyes gleaming. “Already so desperate for me. I bet your panties are soaked.”

Jamie whimpered, unable to deny it.

Lena’s hand slid down Jamie’s body, teasingly slow, until she reached the hem of her dress. “Should I check?”

Before Jamie could answer, fingers brushed against her inner thigh, moving higher…
