Replacement Test

"Never thought I'd be giving a blowjob in Chad's living room," Lilly muttered, her hands trembling as she undid Kyle's pants. The thought of her brother finding out sent a chill down her spine. Sarah's assuring words echoed in her head, but they did little to calm her nerves. She glanced around, making sure they were still alone, before slowly taking out Kyle's thick cock. "You're sure he won't see me?" she asked, more to herself than to Kyle.

Kyle chuckled softly, his eyes fixed on her face. "Trust me, he won't." He let out a pleased groan as she wrapped her lips around the head of his cock, her tongue swirling around the slit. "You're doing such a good job, sweetheart," he murmured, reaching down to cup her head, guiding her movements. Lilly closed her eyes, feeling a mixture of shame and arousal wash over her. She knew she wasn't very good at giving blowjobs, but the way Kyle was making her feel right now... it was intoxicating.

She tried to focus on pleasing him, sucking harder and taking more of him into her mouth, her tongue flicking against the sensitive skin behind the head. She could feel the warmth of his body against her, and the musky scent of him filled her nose. "Well, it's not terrible," Kyle groaned, his hips bucking forward. His fingers tightened in her hair, urging her to take more of him.

Lilly didn't want to disappoint him, but she still couldn't quite find the rhythm that seemed to please him. Her tongue went all over the place, and she couldn't quite figure out how to take him deep into her throat without gagging. Kyle's hands held her head firmly, guiding her movements, but she could tell by the look in his eyes that something was still missing.

"Maybe if I...," she stammered, hesitantly trying to deep-throat him. She gagged, feeling the tip of his cock brush against the back of her throat. "Is... is that what you like?" she asked, her voice muffled. Her mouth was getting tired, and her saliva began to leak onto the carpet.

Kyle let out a long sigh before pulling her head back. "It's not bad, Lilly," he assured her gently. "It's just... not quite what I had in mind." He paused for a moment, thinking. "Why don't you just undress?" he suggested.

Lilly looked hesitant as she took a step back, her hands trembling slightly. She glanced at Kyle, her eyes darting around the room before meeting his gaze again. "I-I don't know..." she stammered.

Sarah chuckled softly, laying a reassuring hand on Lilly's shoulder. "Trust me, sweetie, Chad won't be home for hours. We've got plenty of time," she assured her, her voice low and soothing.

After a moment's hesitation, Lilly nodded. "Okay," she whispered, her heart racing with a mix of fear and arousal. Slowly, she unbuttoned her blouse, revealing her small, perky breasts. Kyle's eyes widened as he took in the sight of her exposed chest, his gaze trailing down to her nipples, which were already hard and erect. She shivered slightly under his intense stare.

"That's it, sweetheart," Sarah encouraged, sliding her hands up Lilly's arms and over her shoulders, helping her remove her top. Lilly felt self-conscious and exposed in just her bra and panties, but Kyle's appreciative gaze helped calm her nerves. She blushed as she reached down to slide off her panties, which softly fell to the floor without a sound.

"There you go," Sarah smiled, giving Lilly a reassuring squeeze. "You're doing great." Kyle's gaze traveled up and down Lilly's naked torso, taking in the sight of her flat stomach and visible abs. She blushed as she noticed his eyes lingering on her midsection. "I hope this is alright," she said nervously.

Kyle smiled and nodded, gesturing for Sarah to undress as well, though he made no move to take off his own clothes. Lilly felt relieved that she wasn't the sole focus anymore. Sarah slowly began to unbutton her blouse, slipping off her bra to reveal her large, ample breasts. Lilly felt a wave of nervousness wash over her as she watched Sarah, wondering whom Kyle was paying more attention to. As she glanced between them, Kyle's eyes settled on her once more.

"Lilly, would you like to help me out?" Kyle asked softly, motioning for her to step closer. Nervously, she approached and reached with her hands to remove his t-shirt, her hands trembling as she pulled it over his head. Sarah nodded encouragingly, and Lilly continued, slowly peeling off his jeans and boxers. He was already hard, his erection standing proudly before them. Lilly's heart raced as she took in his naked body, her hands shaking as she ran them over his thighs and chest.

"Oh, he's quite impressive, isn't he?" Sarah purred, her hand finding its way to Kyle's hardness, moving up and down his length. "Much larger than your brother's." Lilly blushed, feeling her own arousal grow as she watched Sarah fondle the dick in front of her.

Kyle groaned softly, his eyes closed, head falling back against the pillows. "That feels so good, Sarah," he murmured. "But I think I want to focus on Lilly now." He met her nervous gaze with a gentle, reassuring smile. "Lilly," he said softly, "Can you go on all fours for me, honey?"

Slowly, Lilly knelt on the carpet, her knees spread wide as she lowered herself onto all fours. As Kyle gazed at her with desire and tenderness, her mind drifted briefly to thoughts of her boyfriend. She recalled their intimate moments together—pleasant, yet lacking the raw intensity she felt right now. She wondered if the sex itself would be different too.

Sarah moved around behind Kyle, straddling his waist as she leaned forward, her breasts brushing against his back. Lilly watched Sarah's confident movements with a mix of fascination and envy. Sarah seemed to know exactly how to please Kyle, jerking him off while guiding his erection toward Lilly's waiting entrance.

"You can take him inside you now, sweetheart," Sarah whispered, her voice husky with arousal. "Just relax and let him fill you." Lilly started breathing harder, her body tense as she felt Kyle's tip press against her entrance. "Wait, but-" she began, but it was too late as he pushed forward, filling her in one smooth stroke.

Her gasp was muffled against the carpet as pain mixed with pleasure. Sarah held her from behind, her breasts rubbing against Lilly's back as she kept her in place. "That's it, honey," Kyle moaned, his hands gripping the sheets beneath him. "Just relax and let me fuck you."

Lilly tried to obey, her body beginning to adjust to the thickness inside her. She bit the carpet, feeling the first wave of pleasure wash over her as Kyle's hips began to move in a slow, rhythmic motion. "Oh, Daddy, I think she's cumming already." Sarah's voice was a low, husky moan, her words sounding as a far echo for Lilly's ear, as she felt her whole body was shaking.
