Chapter 9

"Final stage?"

"I've noticed that quite often, when you are ready for climax, you will lift my legs like this. In fact, I wonder if you even understand the physiology behind that instinct."

"Why don't you enlighten me, Dr. Brennan?" Booth said as he continued thrusting.

"It serves a variety of functions to enhance the sexual experience. Our previous position was optimized for ease of penetration, with the angle of your erect penis almost perfectly coinciding with the angle of my vagina."

"Yes, I recall you saying that."

"But in this position, with my legs raised, my pelvis is tipped forward. The angle of penetration is not optimized for ease of entry, but maximizing stimulation. The ventral side of your penis – which is far more sensitive than the other sides – is pressed against the throat of my vagina as you thrust into me. And the head of your penis is driven into the front wall of my vagina, pressing into my g-spot, before deflecting deeper into me. Consequently, the stimulation is focused on two of our most erogenous areas of our genitalia."

"Is that so?" Booth asked, picking up the pace and force of his thrusts.

"Yes, and further, by placing my legs on your shoulders, you are using my legs much like a leaf spring – allowing you to thrust more forcefully into me, as the muscles and tendons of my legs absorb some of the impact that would normally be focused on our pelvises, and could conceivably lead to discomfort or actual injury."

"There's a lot of science going on here, Dr. Brennan."

"Yes, there is. And it is quite impressive how many people who don't understand things like physics and physiology still manage to use them so successfully on such an instinctive level."

"You could just say that God gave us that understanding as part of His gifts to us."

"Or, alternately, it could be a form of racial memory, the development of sexual techniques as instincts to maximize pleasure. Or, even, the result of trial and error by each individual."

"So, are you about ready to bring this procedure to a conclusion, Dr. Brennan?"

"I have already experienced several small orgasms, and can feel a very significant one building, so I would have to say that I am rapidly approaching the point where that would be… proper." She smiled again. "Further, I can tell that your own orgasm is quite near."

"How can you tell that?"

"Your penis has swelled slightly, increasing in length, girth, and firmness to a barely-noticeable degree. That indicates that your sperm has left your testes, mixed with your seminal fluid, and has advanced up your urethra. I would conclude that you are on the verge of an orgasm, but holding back."

"Why would I do that?"

"Two reasons. From my understanding of male sexuality, the sensation of being on the verge of orgasm is an intensely pleasurable sensation, second only to orgasm itself. But the orgasm is fleeting, while the pre-orgasm plateau can be quite prolonged. So on that basis, you want to hold back your climax as long as possible."

"That sounds like a good reason, Dr. Brennan. And the second?"

"Ego. You consider yourself a most proficient lover – and you are. But you want the affirmation of that by making me achieve my orgasm first. Only after I climax can you fully let yourself go and enjoy your own."

"And you have a problem with that?"

"I'm afraid I do. I, too, share the same ego issue, and would find it most satisfying to force you to climax first. It's a matter of will – the one to climax last would have the bragging rights of 'giving' the other their orgasm, and be seen as the less selfish and more generous and more talented lover. It's a small matter, but where both of us are individuals of great will, it guarantees that we will conflict over this. Which is actually a good thing, as it prolongs our intercourse and greatly intensifies the sexual pleasure for both of us. It's a large reason why we are so sexually compatible."

"So… it's a contest between us?"

"Yes. And it's a contest where neither of us loses – just one wins a tiny bit more. And the harder we contest with each other, the more we both win."

"Well, Dr. Brennan, I should assure you that I fully intend to 'win' this time. I'm going to make you cum first, no matter what I have to do." With that, he took one of his hands off the bed, snaked it along his hip, and began caressing her clitoris while he continued to thrust into her.

"Mmm… that's very nice, but it's not going to work this time, Agent Booth."

"Oh, really?"

"Really. Yes, you know my physical triggers, but I know your psychological ones. If you were to continue stimulating my clitoris while we engage in intercourse, you would achieve your goal of making me orgasm first. But your trigger works much faster, and I can still use it before you succeed in making me climax."

"I find that very hard to believe, Dr. Brennan. I know you and your responses, and you're less than a minute from a very, very big orgasm. I don't think you have the time."

"Agent Booth, I have all the time I need. Your trigger is a verbal expression of my desire and acceptance of you as my lover, accompanied with an explicit request that you complete the sex act."

"Dream on, Dr. Brennan. You are going to come first, and there's nothing you can do to change that."

"Oh, really?" With that, she reached up and took his head in her hands, forcing him to meet her gaze. And then, while staring into his eyes, she set aside the clinical tone and let her passion drive her voice into a deep, breathy, commanding tone barely above a whisper.

"Seeley, I want to feel you come in my pussy. I want to feel you fill my pussy with your come."

That did it. Booth's spine snapped, and he began thrusting wildly. In seconds, both of them finally released their orgasms, and pulled each other as close as they could as he poured himself deeply into her.

"The application of the verbal stimulus was most efficiacious. Subject Booth thrust three more times after the conclusion of my statement, and then released his orgasm. He experienced between four and seven ejaculatory contractions. I lost track of the precise number, as the second such contraction triggered my own exceptionally powerful orgasm and I was unable to maintain focus."

Booth was amazed. He was barely getting his senses back, and Bones had picked up the verbal recorder off the nightstand and was continuing to document the sex. "Would you like me to get off you?"

"Not just yet. Your penis is still largely erect, and I find it most pleasant to have it inside me. It is growing less tumescent with each beat of your heart, and that, too, is a fascinating sensation. Once it comes out of my vagina naturally, then I might consider asking you to get off me, but for the moment I am getting a great deal of satisfaction out of our physical closeness. However, I believe that we have successfully concluded this procedure." And with that, she hit the stop button on the recorder.

"So, how did you like it?"

Apparently, "Dr. Brennan" was turned off with the recorder. "Seeley, it was fantastic. I've always enjoyed sex with you, but this time, by forcing myself to examine every single aspect of it from a scientific perspective, I found myself enjoying things that I'd only been vaguely aware of. Figuring out your little move there, understanding the differences of when my legs are around you versus up on your shoulder, even telling just when you're on the verge of coming – I'd understood all those things on a purely subconscious level. But now I fully grasp them, and can enjoy them even more. Thank you for coming up with this idea."

"Oh, believe me, it was my pleasure. Listening to you get all squinty in bed, talking about sex in such technical terms while we were actually doing it – it was incredible. I love Temperence, and I love Bones, and this was like having both of you in bed at the same time."

"So, this was basically your way of having a threesome?"

"That's not what I meant."

"Yes, I know, but I couldn't resist." With that, his penis finally slipped out of her vagina. He rolled on his back, and she snuggled up against him, her head in the hollow of his shoulder. He pulled her tight, his hand tenderly caressing her back and buttocks. They lay there in a contented silence for a few moments.

Then he noticed she was looking past his chest, and a sly smile was creeping across her face. He glanced off to his side, and realized she was looking at the recorder. "Thinking about playing it back?"

"Not exactly."

"Erasing it?"

"Definitely not."

"Then what?"

"I was wondering which would be more inappropriate – giving it to the transcriptionist at the Jeffersonian, or the transcriptionist I use for my novels."

He slapped her on the ass – just hard enough to count as a slap. "How about we just keep that to ourselves?"

"Seeley, that would be incredibly selfish. We have made a remarkable discovery here, and we owe it to the world to share it."

"Definitely not."

"We could at least give a copy to Dr. Sweets. It could be tremendously valuable in his research."

"Sweets? You want us arrested for giving porn to a minor?"

"Despite his youthful appearance, Dr. Sweets is no minor. And from what Miss Wick has insisted on sharing with me, he's also no innocent. I think he would find it a priceless resource."

Booth sighed in exasperation. "I see I'm going to have to shut you up again." With that, he rolled her back on her back and crawled atop her again, smothering her giggles with his mouth.
