"If we were in a room full of art, I would stare at her"

The CSU team moved away to photograph entrance points on the scene. Spencer Reid knelt by the corpse and observed it.
From behind him, Luke said,
"This guy's MO is as common as they come. Middle-aged women, strangled in their own homes. The body is on the floor in a random position. There's no way for us to distinguish these from a regular home invasion killing"
"Actually, there is", Reid pointed, "That's a large bra for a woman of her proportions. It's heavily padded and quite fancy for our victim. She had just come home from a run. If anything, she must have worn a sports bra. And those do not look like this"
Reid stood up and spoke in a grave tone.
"He's dressing them"
Luke said so only they could hear,
"You know a lot about bras"
Clearing his throat, Reid stepped away.
"Excuse me"
He walked over to another corner of the room, keeping his face turned away from Luke.

Last weekend -

Lying in her bed next to her, Spencer tried to get his breathing back. He wasn't a fan of exercise, but he sure didn't mind some post-orgasm exhaustion. Monica too lay panting against him. The breeze from her yard provided some much needed coolness. The heat between them the past forty-five minutes had been ecstatic.
"I read one of your papers yesterday", he gasped.
"Did you now?"
"Yeah. It was quite informative"
"Thank you. Which one are you referring to exactly?"
"The Influence of Abiotic Elements on Azadirachta Indica - An Observation"
"Oh. I wrote that one when I was traveling in South Asia"
"The tone of the paper was quite formulaic, not much like you. It certainly piqued my curiosity about how you are as a professor. Do you follow the lecture method?"
"Not entirely", she got up, "Would you like a demonstration?"
"Sure"
He sat up too, excited to witness Monica in her role as a teacher. She stood by the bed and pulled on her clothes. Mischief shone through her grin.
"Get ready for Sex 102: How to Unhook a Bra"
Sitting up straighter in bed, he defended himself.
"Your bras are extremely complicated"
"They are not! You just need a basic lesson. It's nothing to be embarrassed about", she winked at him, "I'll teach you"
"Is this about that day when I was looking for the hook on your sports bra?"
Monica turned her back to him. He could see her shoulders bounce and hear the mirth in her voice.
"No"
Spencer was grinning,
"You're laughing at me!"
She turned around to him, red in the face, the corners of her mouth upturned.
"I'm sorry! It's just so cute that a genius like you can't figure out a bra", she started laughing again.
"My genius doesn't have to extend to women's underwear"
"But now it will", she composed herself, "Because, I'm going to model my bras for you. I will also teach you how to get them off me"
Before he could finish saying "Monica", she had thrown open her closet. He couldn't help peeking in and getting a glimpse. It was well-organised, looked like it was sorted by colour too. Monica pulled out her underwear drawer.
"How many bras do you have?"
"Nine. But don't worry. I'm just going to show you three to four major types"
He watched as she pulled off her top and put on a bra. To his dismay, she had her back to him. But then, wearing her little green skirt and a skin coloured bra, Monica catwalked to the bed. She struck a pose and told him.
"This is my regular, lightly padded, size 36 bra. The black one I was wearing earlier is a variant of this"
She walked and perched herself next to him on the edge of the bed. Her back was to him as she pulled her hair over one shoulder and demonstrated. Monica arched her back.
"This is how you unhook it. You take the end of the hook strap above, tug it forward, then release it. Simple, right?", she hooked it again, "Now you try it"
Spencer leaned forward, eager to learn, and followed her instructions. The bra was unhooked in an instant.
"This is so simple", he remarked.
"Told you"
Monica got off the bed and turned to him. Her hand was holding the bra to her chest.
"Now the next one", she said.
She went to the closet and, with her back to him again, put on a different bra.
She walked to him again, one hand on her hip, and posed.
"This is a tube bra. Like the sports bra, it has no hooks. You can just pull it off like a tshirt"
Raising her arms, she took the bra off. Reid's mouth hung open. Her back wasn't to him anymore. Though he had seen her breasts before, they still had their usual effect on him. He adjusted the sheets over his lower half.

Monica turned and walked to the closet again. He had regained control of his jaw by the time she returned.
"This here, Dr. Reid, is one of my fancy bras"
The array of straps across her shoulders proved so.
"It's heavily padded. As you can see, it's crimson in colour. I call it my date bra 'cause when I wear it on our dates, you can't stop sneaking peeks at my chest"
"What do you take me for?"
"A red-blooded, heterosexual man", she turned, "And it's unhooked just like my regular bras. You can just slip the straps off my shoulders like this. Got it?"
"Yep"
Monica walked to the closet again and put another bra on. When she turned around, her cleavage could have been made from a mile away. Spencer watched transfixed as she walked to him.
"And this is my strapless, push-up bra. It's also known as a balcony bra because...", she motioned to her cleavage, "You get the gist"
He was nodding when Monica walked to him and climbed upon his lap. She smiled at him.
"Now take it off"
Spencer put his hands behind her back and tried. Monica chuckled.
"You're not defusing a bomb. Relax. It works just like a regular bra"
He succeeded in unhooking it. His fingers grazed the hard lining on it as he took it off.
"What's this under the..."
"Cups", she finished for him, "It's the underwire. It helps the bra retain shape and creates cleavage"
"I see"
"Do you like what you see?", she put her arms around his neck.
Spencer gingerly touched her left breast.
"Yeah", he murmured.
Monica leaned against his palm, making him catch his breath. There was one of those smiles on her face as she eyed him like a cat.
"You", he said, "Um, you're a good teacher"
"Well, I don't usually teach my students to unhook my bra. Botany is a little more complex"
He gave a laugh, meeting her eyes.
"I do feel... educated"
"Is that so?"
"Yeah"
"I'm glad I could be of service"
He glided his hand along her back. Monica pulled him down so his head was on the pillow. Spencer spoke between kisses,
"Do you... have... class... evaluation forms?"
She giggled against his mouth and let him topple her. They spent a better part of the night making love, with smiles on their faces.
