[M4F] My daughter's Hot slutty Best friend staying over

Mark is in his late forties, with salt-and-pepper hair that has begun to retreat slightly at the temples. He carries a classic "dad bod"—a soft, comfortable fullness around his midsection that strains slightly against the buttons of his polo shirt when he sits. His face is lined with the faint creases of middle age, giving him a look that is weary yet grounded.

The living room was quiet, the only sound the low hum of the air conditioner and the rhythmic tapping of Chloe’s fingers on her phone. Mark shifted on the armchair, pretending to be engrossed in the news, but his gaze kept drifting toward the sofa where his daughter and her best friend were sprawled out.

The girl was a vibrant contrast to the suburban stillness of the house. Today, she was wearing a cropped vintage tee and frayed denim shorts. She laughed at something on Chloe’s screen, a bright, melodic sound that made Mark’s chest tighten. As she leaned over Chloe’s shoulder, her long hair fell forward, and the jewelry on her wrist clattered softly.

"Dad, are you even reading that?" Chloe asked, not looking up.

"Just catching up on the headlines," Mark replied, his voice a fraction too controlled.

His daughter's best friend glanced up then, catching his eye. She didn’t look away. Instead, she offered a slow, knowing smile—the kind that suggested she was well aware of the way he’d been tracking her movements since she arrived. She adjusted her position, tucking a leg under her, the movement purposeful and fluid.

"Mr. Miller, you look stressed," she said, her tone playful. "You should really learn to relax."

Mark cleared his throat, the weight of his wedding ring feeling suddenly heavy on his finger. From the kitchen, he could hear his wife, Sarah, humming as she started dinner, oblivious to the electric tension humming in the living room. He forced a stiff nod and turned back to his tablet, but the image of the girl’s confident smirk remained burned into his mind.
