Lily's breath caught in her throat as Mark's warm, rough hand slowly slid higher up her smooth thigh. His fingers disappearing beneath the hem of her tiny pink shorts, stroking the sensitive skin there with deliberate, teasing movements. Every inch he gained sent fresh sparks of electricity shooting straight to her aching pussy.

She was soaked. Embarrassingly wet. She could feel her juices coating her inner thighs, threatening to drip if he went any further.

Oh God... this is really happening, she thought, her heart hammering so hard she was sure he could hear it. He's touching me. My stepdad is actually touching me.

Mark's eyes never left hers. That dark, hungry look had completely taken over now - the polite, fatherly mask gone. His thumb drew slow, maddening circles on the inside of her thigh, inching closer and closer to where she needed him most.

"I have always had my eyes on you, Lily," he said suddenly, his voice low and rough, like gravel wrapped in velvet. "You grew up into such a beautiful young woman. So fucking beautiful it drives me crazy every single day."

The confession hit her like a punch to the gut. Heat flooded her entire body. Her nipples tightened painfully against the thin white top, begging for attention.

"I want you so much," Mark continued, his breath hot against her cheek. "I know this is wrong. I know I shouldn't be thinking about my stepdaughter like this... but I can't stop. Every time you walk around the house in these little shorts, every time you bend over... all I can think about is bending you over myself and fucking you until you scream."

Lily whimpered softly, her hand gripping his thigh tighter. Her pussy clenched hard at his filthy words. She had never heard him talk like this - raw, desperate, possessive. It made her feel like she was going to melt.

"I want you too, Daddy," she whispered, her voice trembling with need. "I've wanted this for so long. Every night I touch myself thinking about you. My body gets so hot... I have to clench my thighs together just to stop myself from dripping when I see you."

Mark groaned deeply, the sound vibrating through his chest. His hand moved higher, his fingers brushing against the soaked crotch of her shorts. He could feel how wet she was.

"Fuck, Lily... you're dripping for me already?"

She nodded shamelessly, spreading her legs wider for him. "Yes, Daddy. All for you."

That was all it took.

Mark pulled her closer with a growl and crashed his mouth against hers. The kiss was hard, hungry, and desperate - nothing like the gentle stepfather she had known. His tongue pushed into her mouth, claiming her, tasting her. Lily moaned into the kiss, her hands flying up to grip his broad shoulders as their tongues tangled hotly.

The kiss grew deeper, filthier. Wet sounds filled the dark living room as they devoured each other. Mark's hands roamed over her body - squeezing her waist, sliding up her ribs, finally cupping her full, soft breasts through the thin top.

Lily arched into his touch, moaning loudly when his thumbs brushed over her hard nipples. He pinched them gently at first, then harder, rolling them between his fingers until she was whimpering against his mouth.

"You have no idea how long I've wanted to touch these," he growled against her lips, squeezing her tits possessively. "So fucking perfect."

He pushed her top up roughly, exposing her bare breasts to the cool air. Her pink nipples stood hard and begging. Mark pulled back just enough to stare at them, his eyes dark with lust.

"Beautiful," he muttered, almost to himself.

Then he leaned down and took one stiff nipple into his hot mouth, sucking hard. Lily cried out in pleasure, her back arching sharply. His tongue flicked over the sensitive bud while his hand kneaded the other breast, occasionally spanking it lightly, making her flesh jiggle.

The sharp little smacks mixed with the wet sucking sounds drove her wild. Her pussy throbbed painfully, begging to be touched.

Mark switched to the other nipple, giving it the same rough treatment - sucking, licking, then biting down gently. Lily's hands tangled in his hair, holding him against her chest as she moaned shamelessly.

"Daddy... please..."

He pulled off her nipple with a wet pop and looked up at her, eyes blazing. "Please what, baby girl?"

"Touch me," she begged, her voice breaking. "Touch my pussy. I'm so wet for you."

Mark's hand immediately slid down her stomach and into her shorts. His thick fingers found her dripping slit and rubbed her swollen clit in firm circles.

"Fuck, you're soaked," he groaned. "This little pussy is dripping all over my hand."

Lily moaned loudly, her hips grinding against his fingers desperately. He pushed two thick fingers inside her tight heat, curling them against her inner walls while his thumb kept working her clit.

The pleasure was overwhelming. She could feel her orgasm building fast, her thighs shaking.

But Mark suddenly slowed down, teasing her right on the edge. He kissed her again, deep and possessive, while his fingers worked her pussy with expert precision.

Then, without warning, he pulled his hand out of her shorts, grabbed the hem of her thin white top, and yanked it up and off in one swift motion.

Lily sat there completely topless, her full breasts heaving with every breath, nipples shiny from his mouth. Mark stared at her naked chest with raw hunger, his eyes drinking in every inch of her.

"Goddamn, Lily..." he breathed, reaching out to squeeze both breasts hard, watching them spill between his fingers.
