Thanks for the reviews and alerts. This one is the sex talk EmmyMayyy suggested.

This is a B&B established relationship:)

The shout out goes to kaloblack who tossed ideas back and forth with me and gave this a read. (She was more than a Beta for this one:)

"No 'buts', Bones. We'll wait for you at the diner." Before Brennan could say something else, Booth hung up.

Originally Booth was going to pick Brennan up for lunch, but Rebecca had allowed Parker to have lunch with his dad. Brennan had told Booth that she didn't want to ruin his father-son time, but he told her he wouldn't have any of that. He was going to pick up Parker and Brennan would meet them at the diner. And Booth had made it very clear that if she didn't go, they would come to take her for lunch.

Booth and Parker made it to the diner before Brennan. They ordered their food and since Brennan had told Booth she'd be there soon, he ordered her favorite salad for her. Parker talked about his week and Booth listened intently as their food arrived.

"Can I ask you a question?" Parker asked his dad.

"Of course, Parker. You know you can talk to me about anything you want." Booth told his son sincerely, not imagining what his ten year old son had to ask.

"I know, it's just my friend Peter asked his mom a question and she fainted." Parker stared at Booth, waiting for his dad to say something.

"What is it?" Booth asked as he took a drink of his soda. Booth chocked on his drink and coughed as it hit him what his son wanted to talk about. The question the child wanted answered.

Brennan saw Parker and Booth sitting at the usual table they used by the window. Booth's back was to her, so it was only until she sat next to him that she noticed he was coughing.

"Hi, Parker. What's wrong with him?" Brennan asked the boy with a smile.

"Hi, Bones." Parker greeted back with a smile. "I asked him, why do girls have periods and boys don't?" Brennan tried to hold back her chuckle as she understood what was wrong with Booth. Booth turned red as a tomato at hearing the question again and seeing that Brennan was trying to hold back her laughter. She's enjoying this. Booth thought.

Parker said how the boys and the girls were shown a video, separately, of the changes their bodies would undergo during puberty. Parker and his friend Peter heard the girls talking about how they were going to get their periods and he wanted to know why boys wouldn't get one.

Seeing that Booth was stuttering to answer the question, Brennan decided to answer the boy. "Girls have periods because they have a uterus and the uterus sheds it's lining monthly if there isn't a pregnancy. Then it starts building up the lining again, then there's ovulation, the egg comes down, if the egg doesn't get fertilized then the uterus sheds its lining again to prepare for the next cycle…" Booth watched mouth wide open as Brennan went on explaining and as he saw that his son was nodding.

"OKAY, that's enough. Parker doesn't need a doctorate on the subject." Booth cut Brennan off before she drew the child pictures.

"It's best he hears it from someone who knows instead of getting the wrong information." Brennan turned to Booth and told him that educating children at an early age is helpful for their development. Booth shifted on his seat, he was very uncomfortable at the moment.

"Thank you, Bones." Parker told Brennan, thankful she had answered his question. The child ate his lunch and Brennan did the same. Booth was amazed at how Brennan and Parker were able to move on to their food after that conversation.

B&B

After lunch Booth drove his son back to Rebecca's. "Hey, when I have you next weekend I'll be prepared to answer any more questions you have." Booth told his son once he parked the SUV in Rebecca's driveway. Booth knew his son was growing up and his Bones was right, it's best if Parker gets the right info.

"Thanks, daddy." Parker hugged and kissed his dad goodbye, proud that his dad was willing to answer questions of that sort.

Booth pulled out of the driveway and made the mental note to stop by his local library to grab a book that would help him have that talk with Parker.

B&B

It was Thursday night and the partners went to Brennan's place to celebrate the closure of their latest case. They finished their Thai food and sat on her couch to drink the rest of their beers, enjoying each other's company.

"I got you this." Brennan gave Booth a book that would help Booth answer any questions Parker could ask about bodily changes and stuff of that sort. "I know you have him this weekend…this will help make it easier for you to answer his questions." She took a drink from her beer and Booth thanked her as he took the book from her. "What I don't understand is how you can talk about your conquests in high school, but you can't answer a ten year old's question." Brennan told him with a light chuckle. "And I know you're not a prude."

Booth placed his head on her lap and stared up at her. "Hey, that's not fair." He told her with a fake shocked expression. Brennan smiled and shook her head. "Look, it's just…my little boy's growing up. I just didn't expect him to ask me that question. I wasn't prepared." He leaned up to kiss her sweetly. "Thanks for answering his question and for the book." He shot her his charm smile. "And it was hard for me to talk about sex with you before we became a couple because it was hard to talk and not do it with you." He told her suggestively, leaning forward to place a passionate kiss on her lips.

Clothes flew as they made their way to her bedroom. Kissing they fell on the bed as their lips and hands roamed the other's body.

He entered her in one quick thrust and together they set a satisfying rhythm.

"Booth!" She screamed his name as her orgasm shook her body. Her name left his lips as he shot his load inside her heat.

They kissed as he rolled them to lie on their sides. Smiling and laughing, they snuggled close to each other.

The next morning as they headed out of her apartment, Brennan told Booth that he would do fine when he had his talk with Parker. Kissing her, he thanked her and drove her to the Jeffersonian.

B&B

That weekend Booth had his talk with Parker and as the conversation progressed, Booth eased and found that it was easier than he had thought.

Let me know what you thought of this one:)
