"It's the enhancer, Cat." His voice dropped to a whisper.

"It's already beginning to heighten your senses." Not to mention his own.

She shrugged and wiggled in her chair. "Maybe it's just because I'm starving." She opened her mouth, inviting him to feed her. "More." There was a note of amus.e.m.e.nt in her sweet voice.

Sam shifted his chair closer, until his legs pressed against hers. Heat flared between them as their thighs collided. He reached out and stroked her cheek. Using small circular mo- tions he brushed the pad of his thumb over her skin, all the while his body language indicating that he was imagining it was another part of her body he was caressing. Her eyes blazed with desire as they locked with his.

He brought a slice of fresh orange to her mouth and held it just out of her reach.

She whimpered, flicked her tongue out, and drew it into her mouth. Eyes closed, her head lolled to the side. A sigh of pleasure filled the room. The erotic vision before him fueled his desire, causing his body to go up in flames.

He had to taste, to have her, to make love to her and have her want him on the same emotional level.

His lips crashed down on hers. Her lids flew open. She gasped in surprise. He drew her orange-soaked tongue into his mouth for a more thorough taste. She leaned into him, deepening the kiss, pressing her lips hungrily into his.

Urgent hands moved over her curves, unable to get enough of her. Unable to get her deep enough under his skin.

"Sam," she whispered through m.u.f.fled kisses.

"Yeah"

She inched back, her smile coy, the gleam in her eyes turning wicked. "I know a better way to test my sense of taste."

Unbridled desire laced her voice.

He felt so crazed with l.u.s.t, desire, and need he couldn't comprehend what she was trying to tell him.

"What are you talking about"

"I think I want to kiss you."

"Cat. We are kissing."

She shook her head. "Not there." Cat stood, pushed her chair away and positioned herself between his open thighs.

He gulped and began trembling from head to toe as her glance traveled down his body and settled on his c.o.c.k.

"What are you doing, Cat"

"Well, I've been dying to taste you again since yesterday, so I thought we could test my sense of taste this way."

"Test your what" he asked, confused.

She chuckled. "The experiment, Sam. The serum. My heightened senses."

"Right," he forced that one word out and nodded in agreement, knowing his need to be with her had nothing to do with the experiment.

Her movements were sensual, seductive as she dropped to her knees, leaned back on her heels, and worked his jeans past his legs. With her mouth only inches from his c.o.c.k, she blew out a breath. His engorged phallus jolted in antic.i.p.ation as the heat of her breath whispered over his thighs. She sheathed his hard c.o.c.k in her hand, her fingers idly stroking, the same way one would caress a pet.

As she licked her lips, he made quick work of his shirt.

"Very impressive, Sam. I should have told you that yesterday."

A rumble of pleasure sounded low in his throat. He could feel her hot mouth so close to his c.o.c.k. Man, it felt so d.a.m.n good. He jerked his hips forward, his d.i.c.k brushing her lips.

"Oh G.o.d, Cat." He took short, panting breaths.

His juices pearled on the top. Her long golden locks fell forward, shadowing her face as she dipped her head. Her tongue slid over his engorged tip, tasting his essence. The silky sweep of her lashes against his skin made him throb.

His body tightened and he nearly shot off in her mouth.

She breathed a kiss over his flesh, taking great pleasure in his size and texture. He took deep fortifying breaths and gathered her hair in his palms, pulling it from her face as she slowly drew the length of him into her throat. Her pretty pink tongue swirled around his head, pushing him to the edge of oblivion. Fire pitched through him, sending his blood pressure soaring.

Sweat trickled down his neck as he became lost in the pleasure of her expert mouth. Her velvet tongue worked harder as she switched tactics. Small, urgent, short flicks around his tip evolved into long determined strokes down his length.

Her tongue played around his heavy sac, forcing it to draw tight inside his body as pleasure forked through him.

She pulled one ball into her mouth and suckled, drawing an o.r.g.a.s.m from his d.i.c.k. Sweet Jesus, that was all he could take.

He gripped her head to ease her off his c.o.c.k. He was going to come.

"Cat ..." he growled between clenched teeth. His muscles began to clench. "Cat ... the bed ... now. I want to be inside you when I come."

She glanced up at him, her gaze revealing her every emotion.

When their glances met something special, unique pa.s.sed between them. The warmth and emotion in her eyes spoke volumes. She felt the same way about him.

He felt a tug in his gut.

Maybe it was higher.

And a little to the left.

He lowered his voice. "Sweetheart, let me make love to you on the bed."

Cat smiled up at him and gave an erotic whimper. Her soft feminine features pulled at his heart as a bolt of emotionally charged energy arced between them.

She glanced at the bed. "I've never had s.e.x on silk sheets before."

His jaw slackened open, clearly appalled. "Then Cat, my love, you haven't been treated properly. Tonight I'm going to rectify that."

Sam was right. No man had ever treated her so properly. Not only did Sam care about her pleasures, but he was eager for them as well. Her heart tightened in her chest as she met his glance. She gazed deep into his eyes and met longing. There was something different in the way he looked at her. Was it possible he saw her as something more than a lab rat She stood, took a small step back, and removed her clothes.

Gaze riveted, Sam's mouth curved enticingly as he watched her step from her jeans and slowly inch down her panties.

She shivered as a chill prowled through her.

"Cat ..." His soft voice pulled her in. "I want you so much."

Sam made a swift move and put his arms around her, firing her blood. She shimmied closer, tangled her arms around his neck, and locked her legs around his hips as he picked her up and carried her to the bed, sprawling her across a splash of silk sheets.

The silk felt cool against her heated flesh. He leaned over her. His gaze held her captive as he pressed his lips over hers.

His kiss was full of pa.s.sion, tenderness, emotion. "I need to taste you again, Cat."

Her heart pounded and her breath stalled. Her p.u.s.s.y muscles began to undulate and clench at his promising words.

Positioning himself between her spread legs, he leaned in close. With a feathery light caress he pulled open her swollen folds. She shuddered as he inhaled her aroused scent.

He looked at her with such desire she thought she'd melt all over the sheets. "You're beautiful," he whispered, his voice harsh, rough. He pushed one finger inside her

drenched p.u.s.s.y, the pad of his thumb nudging her c.l.i.toris.

Rhythmically, he eased in and out of her quivering channel.

She moaned and pitched forward.

He growled at her responsiveness. "Your responses make me wild."

He pulled his finger all the way out, cupped her backside, and lifted her a.s.s off the bed. He brought his mouth close to her p.u.s.s.y and inhaled. His nostrils flared. "You smell so good." His warm breath heated her nether lips to the boiling point.

"Please, Sam ..." she begged. With that he answered her urgent plea and sank his mouth into her heat, feasting on her.

She arched right off the bed. "Oh Sam!"

"You are so hot, Cat."

The room began to spin as Sam seared her c.l.i.t with his tongue. His fingers moved back inside her needy fissure to play with her oversensitized G-spot. Her head whipped to the side; her throat went dry. She licked her lips and took deep gulping breaths as the pressure of an o.r.g.a.s.m mounted.

"Come for me, baby. Let me taste you again."

His words, his voice, and the tenderness in his eyes pushed her over the edge. He sucked harder on her c.l.i.t, drawing it into his mouth, playing with it.

She opened her mouth in a silent gasp as stars danced before her eyes. She thrust forward; her body convulsed.

Powerful emotions surged through her as a wave of liquid heat rushed to his mouth. Every nerve in her body vibrated and burned from sensory overload, but she couldn't tell whether it was from the serum or from being with the man she loved.

He climbed up her body and lightly, lovingly brushed his lips over hers. He grabbed a condom from the side table and slipped it on. Nestling back between her legs, his c.o.c.k probed her opening as his gaze bore into the depths of her soul. He brushed her hair from her face. Her heart jumped.

His intimate touch was different. Less physical, more emotional.

She touched his cheek, her need for him completely overwhelming her. "Sam, make love to me."

"My pleasure." He closed his mouth over hers, swallowing her gasp as he plunged into her. She held him tight, hugging him as his lovemaking stirred all her emotions. G.o.d, he felt so wonderful. She'd never experienced such raw, intense need in her life.

He pumped, she arched, and all rational thought dissolved.

Balancing on his arms, his muscles tightened and flexed.

Together they established a rhythm. His heat reached out to her, curling around her, warming her from the inside out.

His voice was low, rough. "You are so hot and tight, Cat.

I won't last."

"I'm already there again, Sam," she whispered, running her fingers though his hair, pulling, tugging, needing all of him, yet not able to get him close enough.

She drew him to her. "Hold me." He slipped his arms under her shoulders and pressed his chest against hers as another o.r.g.a.s.m washed over her.

Their bodies fused as one as her s.e.x muscles clenched around his c.o.c.k. "Baby, I feel your hot juices." Sam thrust harder, driving her deeper into the mattress. "Oh G.o.d, Cat."

His c.o.c.k pulsed and throbbed in the depths of her core as he came inside her channel.

He rolled onto his side. Never breaking contact, he brought her with him. She cuddled into a wall of muscle and felt the rapid rise and fall of his chest. He stroked her cheek, brushing her hair from her forehead. When he touched her like that, like he really meant it, her world turned upside down.

They held each other for a long moment, as if their very lives depended on it. Without even thinking about it their fingers searched each other out and linked together.

She drew a deep breath and said calmly, "Sam, I think we have a problem."

"A problem"

She shook her head. "You see, I was so busy making love to you, I forgot to gauge my responses."

"That's not good, Cat."

"Nope, not good at all."

"What does that mean" he questioned in a soft tone.

She frowned. "I'm afraid I'm going to have to run the experiment again."

He shook his head in mock exasperation. "Where are you ever going to find another stud like me at this time of night"

Cat couldn't help but to smile. "It's impossible. So that really only leaves one solution."

"Only one" he asked, no longer able to keep the grin from his handsome face.

"Only one." She crushed her body against his, her hard nipples giving him a silent message.

He blew out an exaggerated breath. "Well h.e.l.l, the things I have to do in the name of science."
