From the episode: 162 Candles - I believe the quote went something like this:

Damon: I have a diabolical master plan

Lexi: What is it?

Damon: If I told you, it wouldn't be very diabolical would it?

Bonnie lifted her gym bag to her shoulder and grabbed the colorful pair of pom-poms. Cheerleading practice today was brutal. Her throat was sore from the 'vocal exercise' their coach had insisted upon. Her arms and legs ached. Her head throbbed. The only thing she could think about was a nice hot shower.

She was a mere two blocks from the school when she had to stop. The gym bag wasn't heavy, but strap was digging into her shoulder. Dropping both her bag and pom-poms to the sidewalk, Bonnie groaned and tilted her head back looking up at the sky. The orange yellow sunset was fading. Its haze danced over the autumn trees that lined the street. The fall landscape was picture perfect.

She didn't notice he was standing only a few feet away.

With her arms crossed over her chest, Bonnie roughly kneaded her sore shoulders. She closed her eyes and rolled her head from side to side.

Bon-nie

The wind filled her ears with the two syllables.

Bon-nie

It whispered again.

Turning cautiously in a complete circle, she scrutinized the immediate area.

"Damon."

She knew she didn't have to speak very loud in order for him to hear her.

The breeze blew again, and Bonnie focused her power. The Magic pulsed through her as she sent a small tremor through the trunk of the large oak tree. Its limbs shifted suddenly and with a flutter of his wings the crow flew from its branches landing behind an enormous bush.

Bonnie smiled to herself. She was getting better at her craft every day.

"Ready. Ok."

The witch spun around to see Damon in a cheerleading stance with her pom-poms in his hands. A big fake smile played across his lips as he daintily put his hands on his hips. When he wasn't in evil vampire mode, Damon was almost likeable.

"Gooooo Stefan!" Damon cheered tossing his arms over his head, adding a small kick with his left leg.

His Caroline impression was spot on, Bonnie couldn't help laughing.

Damon picked up her bag and tied the pom-pom handles to its strap.

"I'll walk you home." He reached out and began to take her hand in his.

"What are you doing?" Bonnie pulled her hand away.

"Since when is holding hands against the rules?" Damon's eyebrows sunk into a V-shape.

"Since when do you want to hold hands?" Bonnie inquired. There was always an ulterior motive behind any of his 'thoughtful' gestures.

"Look at me, Bonnie. I'm carrying pom-poms. If anyone sees me, do you know what that could do to my reputation?" His blue eyes widened in mock horror.

It was hard to resist Damon when he acted so adorably.

His hand brushed against hers, their fingers intertwined. Bonnie looked down her arm at the contrast of his pale flesh against her own mocha skin. Their relationship was scandalous (in more than one way) in this small town. She could only imagine what her grandmother would say if she knew.

Bonnie took in every detail of him that she could. The way he walked, heel toe, heel toe. His steps were silent, compared to the clunking of her sneakers against the pavement. She noted his clothing. He always wore dark colors. She thought about getting him a blue shirt, one that matched his eyes. But then she realized why he always wore such muted tones, they hid the blood stains better.

Blood.

He needed it to live.

He needed to kill to live.

She pushed the thought away. There would be time to dwell on the horrible reality later.

Bonnie glanced down at their hands again. He was tracing his name in her palm with his thumb. Damon couldbe so sweet. She forced herself to remember that it was just an act, a ploy to keep himself safe and undetected.

He was a vampire.

Nothing could change that.

They were on her front porch. Damon placed her bag on the swing and turned to face her.

"May I come in?" He asked politely. It was getting harder and harder to refuse. But she had to. She had to keep her family safe.

"No Damon." Bonnie told him.

"I just thought you might want a bit of privacy." The cocky smile spread over his lips.

"Why would I want privacy?" Bonnie asked as his body leaned into hers, pressing her against the wooden siding on her house.

"Because I'm going to make you scream." His voice trickled into her ear, making her hair stand on end.

"Damon." Bonnie put both her hands on his chest, but he was faster. She didn't even realize his hand crossed the boundary of her sweatpants into her underwear. His cool fingers tickled her thighs as they traced her sensitive parts.

"Not here, please not here." Bonnie glanced frantically at her neighbor's house less than twenty feet away. "Someone will see us."

"No they won't." Damon assured her. "Remember, I can be very persuasive."

Bonnie wanted to protest further. She meant to push him away. They were out in the open – right in front of her house!

The desire for his touch was overwhelming.

Damon caressed her insides with a scissoring motion while he nuzzled his head into the crook of her neck.

"No Biting!"

"I know. I know." He bent his wrist sliding his fingers deeper. They swirled inside her, exploring every bump and ridge. Bonnie heard the soft sound of her own fluids as his experienced digits rode in and out of her. Her thoughts swirled with sensations of his movement.

The witch tightened her embrace bringing the vampire closer to her. She inhaled the faint scents of laundry detergent and shampoo. Bowing her head against his muscled chest she pressed her mouth against his shoulder.

"NO Kissing." He was quick to remind her.

"I didn't." She looked up at him indignantly, prepared to argue the point. Then she lost her bearings for a moment as both legs trembled beneath her. She would have fallen if he hadn't been holding her.

Bonnie panted hard as she recovered from the episode. Damon's chest vibrated with a light chuckle. His fingers moved inside her again and she experienced another loss of composure. Finding his eyes again, the witch looked at him questioningly.

"In-ter-rest-ing." Damon's tone was smooth as he met her gaze.

Bonnie realized that Damon's touch was the sole cause of the weakness. His untiring fingers ran over her erogenous spots repeatedly. Her body trembled. Her legs went numb. Her toes curled up inside her sneakers. The tingles spread through her as she fell limply against him, unable to breathe or think.

Bonnie found herself swept away in a current of ecstasy. The world around her disappeared as she gave herself entirely to Damon. She did scream; calling out his name over and over again. Just like he knew she would.
