Four-year-old Sarah Grace sleeping softly in bed when she was awoken by the sound of grunting.

"Did you hear that?" She looks at her stuffed teddy bear as she sat up. "Are Mommy and Daddy asleep?" She gets out of bed, puts on her slippers, and heads towards her parents' bedroom. She sees lit candles from under the door. "What do you think they are?"

"Mommy, are you…" Sarah Grace gasp to see her parents butt naked in bed, shut the door, and ran down the hall.

The sound of the door shut startled Jenny and Ryan as they separated.

"What was that?" Jenny gasps as she covers herself.

Ryan, surprised, sat up. "I don't know."

Jenny, still clutching the sheet to her chest, realized something. "Oh, God! Sarah Grace!"

"Oh, my God!" Ryan got out of bed and put on his robe as Jenny put on hers. They left their room and start calling for their daughter.

"Sarah Grace!"

"Sweetie, where are you?"

They didn't notice that their little girl was hiding in the closet, traumatized.

Sarah Grace scudded back to the wall clutching her teddy bear as she hears her parents looking for her.

"Why is Daddy on Mommy?" Sarah Grace glanced at it with terror in her eyes. "And where are their clothes?"

Jenny frantically leaves her daughter's room. "Did you find her?"

"Not yet." Ryan gets up from kneeling near the table.

Jenny sits on the sofa, shocked and embarrassed. "Oh, my God! I must've forgotten to lock the door."

Ryan shakes his head. "No, it was probably me who forgot." He walks over to the closet and sees his daughter crouch to the wall as she looks up to see her father. "Hey, Gracie. It's okay, I got you."

Sarah Grace crawls over into her father's arms as he picks her up.

Jenny spots her daughter in Ryan's arms. "Oh, my God. Sarah Grace." Ryan put their little girl on the sofa and Jenny hugged her.

"You okay?" Ryan strokes his daughter's face as she nodded.

"I'm sorry if your father and I scared you." Jenny's face turned red as did Ryan's face is.

Sarah Grace groans in horror as she turned to her parents. "Do you lie on Mommy every night?"

Jenny looks at Ryan, who looked shocked. "Uh…"

Ryan hid his face in embarrassment. "Um, I…uh, you see, I was lying on Mommy because she was freezing."

"Yeah, yeah and Daddy didn't want me to stay cold." Jenny nodded, nervously.

"I don't get what you saying to me." Sarah Grace looked confused just as Nicholas woke up crying.

Ryan gets up. "I got him." He left towards the room.

"What your daddy and I are trying to say is that he was protecting me when I was cold." Jenny looks at her daughter.

Sarah Grace raises an eyebrow. "So, you were cold and Daddy was keeping you warm?"

Jenny gets up and picks her up. "Yeah. He was trying to keep me warm." She carries her to her room.

"That's a lot different from before, is it?" Sarah Grace wondered as her mother place her in her bed.

"It is." Jenny hands Sarah Grace her teddy bear. "So, do you get what your dad and I are saying?"

Sarah Grace clutched her bear to her. "Yeah, I do."

Jenny smiles just as Ryan comes in with Nicholas in his arms.

"Then, what was that sound that woke me up?" Sarah Grace looks at her parents.

"What sound?"

"It sounded like a…" Sarah Grace makes a grunting sound, which made both her parents look at each other.

Ryan rocks his son as he puts his blanket in his mouth. "Uh, that was probably my phone or your mother's phones buzzing."

"Oh."

"Yeah, it was."

Jenny nodded in agreement. "Maybe we should talk about this in the morning."

"Okay." Sarah Grace yawned and rests her head.

"See you in the morning, sweetie."

"Night, honey."

Ryan and Jenny gave a kiss to their daughter as she sleeps and they left for Nicholas's room.

"That was close. I was worried about telling her the whole truth." Jenny kisses her son, who fell asleep in his dad's arms.

Ryan places Nicholas in his crib. "We almost got caught."

"Do you think we did the right thing, telling her that lie to cover up what we were doing?" Jenny looks at her husband as they walk back into their room.

"Yeah, I believe we did." Ryan locks the door behind.

"Good, because I didn't wanna say the truth to her in front of her brother."

"Me either."

Jenny sat on the bed and unties her robe as Ryan unties his.

"Where were we?" Ryan wraps his arm around Jenny's waist and pulls her close to him.

"I think you were gonna thrust my body with yours." Jenny circles Ryan's chest with her finger as she smiles flirtatiously.

"Ah, you sound pretty hot when you mention it."

Jenny giggle as their robes slipped off and the two fell on the bed to continue their sexual romance.

Three-year-old Lily was lying in bed, reading her storybook.

"Jealous of her beauty, she…" She stops to hear moaning.

"What's that noise?" Lily closes her book, gets out of bed and heads downstairs. "Maybe Mommy knows." She walks towards her parents' bedroom and slowly opens the door.

"Mommy, I hear a…" Lily gasps to see her parents butt naked in bed. Castle and Beckett, cover herself, separate, and gasp when they saw their daughter as she closes the door.

"Oh, my God! I thought you lock the door." Beckett clutches the sheet to her chest. "I better talk to her."

"I hope she's alright. Oh, God!" Castle hid his face with his hand as Beckett gets out of bed, puts on her robe, and heads out of their room.

"Lil! Lily!"

Lily sees her mom come out wearing her robe and looking for her.

"Why were Mommy and Daddy hugging, and weren't they supposed to be in their pajamas when Lexi and I went to bed?" Lily hugging her legs to her chest and gasp to see her mom's feet near the table.

"Lily, honey, it's okay. Mommy's got you." Beckett kneels and hugs her daughter.

Lily gets up and walks over to the couch with her mother, but still scared and shocked.

"Look, Lil, about what you saw between me and your dad, that was…well, it was, uh, did it scared you or anything?" Beckett looks at Lily, embarrassed as Lily hides her face in her lap.

Without lifting her head, Lily asks her mom in terror. "Do you always hug like that every day or night?"

"Well, not really." Beckett strokes her daughter's face. "Daddy was hugging me because we love each other."

"So, that's different from when you hug me?" Lily takes a peek at her mom.

Beckett bits her lip. "Yes, very different. Look, your dad and I didn't want to frighten you."

Lily ran her little fingers through her hair. "So, that was a mommy and daddy hug?"

"Yeah, it was." Beckett gets up and takes her daughter's hand.

"How is it different from the hug you gave me?" Lily asks as she and her mother went upstairs and into her room as she climbs into bed.

Beckett tucks Lily in. "Well, the hugs your dad and I gave you were morning hugs, sometimes school day hugs."

Johanna picks up her book. "Okay, I got it now. But how do you explain the ghostly moan?"

"How about we answer that in the morning?"

"Okay, night, Mommy."

"Night, Lily."

Beckett leaves her daughter to read and went back downstairs and into the room.

Castle looks up to see Beckett coming into the room and locking the door. "So, how is she?"

"Oh, I had a talk with her about what she saw, and told her everything." Beckett undoes her robe.

"What?"

"Hey, relax. I didn't tell her the truth; I told her that we were just hugging."

"Like a special hug?" Castle sat up as he sees Beckett disrobing.

Beckett drops her robe to her feet and climbs into bed. "Yeah, the kind of hug we do, not the other we give her." She throws a leg over his hips under the covers. "But I think my talk with her will help understand in time." She leans down to kiss him. "Think I did the right thing?"

"How about we'll talk about it later?"

"Okay."

He pulls her back down into another kiss.

Three-year-old Jesus woke up, feeling thirsty, and got out of bed.

"I need a drink of water and then back to sleep." Jesus quietly walks into the kitchen, takes an empty glass, fills it up, and heads back.

Jesus was heading towards his room with a glass of water when he suddenly heard creaking from his parents' bedroom. "Why is there creaking coming from Mom and Dad's room?"

"Mom, what's that…?" Jesus gasps to see his parents butt naked in bed, and slowly shut the door.

"What the hell?" Lanie separated from Esposito and covers herself.

"You hear something?" Esposito got up, confused.

"Yeah, I think…" Lanie, clutching the sheet to her chest, hides her face.

"What?" Esposito placed his hand on Lanie's.

Lanie looks up. "I think Jesus might've seen us."

"Ay Dios Mio. I'll talk to him." Esposito got out of bed and put on his robe.

"Okay." Lanie lies back as Esposito goes out of the room.

"Jesus! Jesus? Jesus buddy, Donde Esta?"

Jesus hears his dad calling for him from his bedroom.

"Why were Dad and Mom together like that?" Jesus looked shocked. "And why aren't they wearing their pajamas?"

Esposito looks in his son's room.

"Jesus?" He sighs. "I could've sworn I locked the door." He kneels near Jesus' bed to find Jesus, tormented. "Hey, Jesus. It's okay. I got you, buddy."

Jesus comes out from under his bed and hugs his dad.

"Hey, Jesus. You remember what you saw between me and your mom?" Esposito placed his son on his bed as he sit next to him.

"You mean when I saw you and Mom…" Jesus was about to finish but starts whimpering.

Esposito, looking embarrassed, hid his face. "Did your mom and I do something to scare you?" Jesus starts to hyperventilate, but his dad puts his arm on his shoulder to calm him down.

Jesus turns to his dad in shock. "Are you and Mom together every day?"

Esposito's face turns crimson red. "Um, I wouldn't say…" He sighs as Jesus looks at him. "Your mom and I were just having a moment."

"I think I don't feel so good." Jesus fell backward on his bed.

"Look, buddy. I know that was awkward, and I'm sorry you had to see that, but I really care about you and your mom." Esposito rests his hand on his son's shoulder.

Jesus looks up. "So, it was a mom and dad moment, huh?"

Esposito gets up and gives the glass to his son. "Yeah, something between me and your mom."

"Is there a difference between that and those other times with you and me or Mom and me?" Jesus looked confused as he takes the glass and took a sip.

"Those other moments were just for family, father and child, or mother and child." Esposito takes back the glass and rests it on the nightstand. "This one is very different for your mom and me."

"Okay, I get it now." Jesus gets under the sheets. "But why did I hear creaking from your room?"

"Oh, I'll tell you that in the morning."

"Okay, Buenos noches, Dad."

"Buenos noches."

Esposito left his son to sleep and head back into the room.

"Well, how did it go?" Lanie spots Esposito coming into the room.

Esposito locks the door. "I didn't say much, just told him that we were just having a moment just you and me."

Lanie sat up. "Did you do the right thing, telling him everything he doesn't need to know?"

"Yeah, I believe did." Esposito removes his robe, hangs it up, and climbs into the bed.

"That was good." Lanie propped an elbow to hold herself up, clutching the sheet to her body, and sighs as Esposito cover his waist with the sheet.

"No, this…" He grabs her and pulls her to him. "Is good."

"Mm."

They continue their love with a passionate kiss.
