Author's Note: This is the final chapter of the story and it is Rated M for lots of the graphic sexual content so enjoy.

Chapter 14: The Cuddles Conclusion.

Sheldon continues fondling Amy's breasts until her nipples turn bright pink. She moans.

He begins carefully counting each freckle on her chest. Sheldon pretends its part of their experiment as he creates a fun new game for himself by mapping out constellations in space between each little freckle connecting them all with imaginary lines.

Amy glances down at his fingers trailing across her bare chest and arms. Amy giggles then she trembles a bit as she watches him. She quickly figures out what he is doing to her and starts doing the same thing to the freckles on his body.

Amy: "Did you find Ursa Major yet?"

Sheldon: "Not yet. Wait! There it is!"

Amy smiles glad that he is having fun playing with her. But, she is so ready to get this show on the road so she picks up his wandering finger with both hands and puts it in her mouth. Sheldon tries to pulls it away at first, but the unique feeling of her sucking on his finger sends exquisite electric signals straight down to his genitals causing him incredible pleasure. His erection grows even bigger with each lick of her tongue and Sheldon closes his eyes completely flabbergasted by the sensations.

Sheldon: "Oh dear Lord! Your mouth is like magic!"

She takes his finger out of her mouth and smiles at him. Then she looks down at his massive erection and grins even wider.

Amy: "Are you ready for third base Dr. Cooper?"

He suddenly feels very nervous as he stares into her lust-filled eyes.

Sheldon: "Uh…and what exactly is your definition of third base?"

Amy whispers the definition into Sheldon's ear and he gasps out loud when he hears what she wants him to do to her.

Sheldon: "Oh you can't be serious!?"

She smirks at him as she gets off the bed and locates her favorite electric toothbrush.

Amy: "Dead serious. It is time you meet Gerard."

She reaches down and pulls her panties open just enough to give Sheldon a quick peek then Amy turns Gerard on. Sheldon's mouth hangs wide open in complete shock as he watches her do this. He had no idea that women even use their toothbrushes for such a purpose.

A part of him wants to look away totally freaked out by what he sees, but he can't turn away from her. Like all good scientists he is way too curious not to observe her every move. Amy presses the vibrating brushes up against her most sensitive area. She groans and sighs excitedly then she walks back over to the bed and lies down next to him.

Amy: "Here take Gerard and grip him firmly like this Dr. Cooper."

Sheldon: "You actually enjoy this!?"

Amy nods her head and positions the toothbrush so he can take over for her.

Amy: "Yes, and Penny's Cosmopolitan magazine says it great for foreplay."

Sheldon: "Oh Amy that can't possibly be sanitary!"

Amy: "Don't be silly! I don't use him to brush my teeth too. Gerard is only for this purpose and I always sterilized him when I'm done. Besides, this is more sanitary than cunnilingus and fellatio which is what most people do when they reach third base. I didn't think you would be comfortable doing that yet so this is a much cleaner option for us. Come on just give it a try…please."

He frowns at her warily for a second trying to decide whether or not to proceed with this new sexual procedure. But, he can't resist her pouty sweet face. Sheldon realizes there is no going back now so he sighs at her.

Sheldon: "Fine! But, this will definitely not be in my weekly email blast."

He anxiously takes hold of the toothbrush then Sheldon looks at Amy waiting for directions on what to do next.

Amy: "Just pretend you are brushing your teeth, but do it gently."

She smiles up at him as he holds it with both hands and closes his eyes so he can concentrate better. Sheldon has always had very good oral hygiene, so he moves the toothbrush in small soft circular motions like he knows nine out of ten dentists recommend. He moves Gerard around as though he were massaging his gums.

Sheldon can't believe she is making him do this, but when Amy starts moaning louder he quickly forgets all about how totally strange this whole thing seems. He finally reopens his eyes to look at her as she calls out to him enamored with how hot she looks in this spread eagle position.

Amy: "Mmmmm…yes….don't stop Sheldon! Don't Stop! "

He continues to softly probe her genital area with the toothbrush and Amy begins to squeeze the sheets with her hands. She arches her back and pelvis upward breathing heavily then Amy moans out loud again.

Amy: "Ooooo…yes….now move it to the left a little."

Sheldon studies her facial expressions and body cues with total fascination. He moves the toothbrush to the left and Amy grabs hold of his wrists in a tight grip lock.

Amy: "Just like that! Yes… Sheldon… Yes! Oooo…right there! Faster!"

Her passionate moans remind him of his Flatland fantasy about her and he innocently blushes more and more with every pleasurable sigh and moan that comes out of her mouth. Sheldon probes her faster and Amy throws her head back against a pillow as she shakes and comes. Then she buries her face in the pillow trying to muffle her screams.

Amy: "Oh yes! Yes!"

Sheldon watches and listens to her every move amazed by all the new sights and sounds he is currently witnessing. He replies in a calm and interested manner to her reaction.

Sheldon: "Remarkable."

After a few more seconds of erotic spastic shaking Amy finally composes herself enough to grab on to Gerard. She turns the electric toothbrush off and pulls it out of her panties. Sheldon reaches for his notepad and pen again to write down his new sexual discoveries.

He had no idea being intimate with Amy would be like this, but Sheldon notices right away that both his ears and genitalia are throbbing together in unison. He adds this information to his growing list of sexual symptoms and then he looks back at Amy.

Amy: "That was amazing!"

She leans over the bed to quickly check the time on Sheldon's Star Trek watch.

Amy: "My god usually it takes me and Gerard at least ten minutes to reach orgasm, but you managed to get us there in fewer than seven. You're a natural at this Dr. Cooper!"

Sheldon: "Thank you. I've been using a toothbrush at least three times a day, every day since I was two years old, so I've got a lot of practice just not quite in this context."

Amy: "Well now it's your turn! Let me give you a massage."

Sheldon: "Uh…alright, but don't come near me with that toothbrush!"

Amy nods at him and puts Gerard away inside the top drawer of the nightstand.

Amy: "Lie down and turn over on your back."

He lies down in the middle of the bed on his stomach while Amy hovers over him. She firmly begins to massage his back and shoulders with her hands kneading each and every muscle. Amy kisses his shoulder blades then she presses her naked chest against Sheldon's back.

Sheldon: "Oh my…. you're skin is so soft."

Amy: "Thank you. I've used lotion at least four times a day, every day since I was three, so you know I've been properly moisturized for years."

She continues rubbing and kissing his shoulders for a few more minutes until she pats Sheldon on the side to get his attention.

Amy: "Okay, its time to slide into home plate."

Sheldon: "What is with all the baseball metaphors?"

Amy sighs and tries hard not to laugh at his confusion.

Amy: "Just turn over."

He sighs at her then quickly turns onto his back and props the pillows up behind his head. Amy removes Sheldon's underwear with both hands then she straddles herself over his waist. Amy tries the pretzel move on him again and continues rubbing him all the way down from his chest to his aesthetically pleasing genitals.

She slowly twists and turns her fingers up and down on his penis and Sheldon's eyes nearly pop out of their sockets. Sheldon starts yelling out strange Klingon words like a crazy person. He swears in Klingon and bites his tongue to keep from coming right away. She has no idea what he is saying, but she can tell by his facial expressions that he won't be able to hold out much longer so Amy stops moving her twisted pretzel fingers.

Amy: "Sheldon! Sheldon! Breathe baby, just breathe. Don't release yet!"

Sheldon grabs Amy's shoulders and pulls himself up closer to her, but she just pushes him back down on the bed again like a true dominatrix. She leans down and kisses him once on the lips hard then she bites his ear. The pleasurable pain of it distracts him just enough to keep Sheldon from exploding. Amy sits up again then she takes a big deep breath and inhales in as if she is about to go swimming underwater.

Amy closes her eyes then in one quick flash she presses herself down on top of his penis.

His eyes pop open again very wide and he grabs hold of the bed sheets surprised by the tightness of being inside of her for the first time ever. He looks up at Amy and realizes she actually looks scared now like she is in pain. Amy keeps her eyes closed as she waits for the initial shock to her genital area to subside. Sheldon gently leans his head up and kisses her cheek hoping that his kiss will relax her a bit then he buries his face in her hair.

After several awkward moments of stillness Amy finally feels comfortable enough to move her body again. She begins to rock her hips slowly back and forth trying desperately to adjust to his size. At first it feels very strange and awkward, but when Amy hears Sheldon moan she realizes the pain is not so bad and she starts to relax her inner muscles. She continues rocking her pelvis against his and within seconds he is almost ready to climax.

Sheldon: "Oh God! Oh God! OHHHHHHHHHHH… MY… GO… STOP AMY!

He has one last relapse back to his crazy old Sheldon as the scary uncertainty of the moment takes over his senses. Sheldon panics a bit and tries to push her off him, but Amy grasps on to his shoulder tightly pushing him back down on the bed again so he can't escape her. Then she looks into his worried eyes while gently stroking his hair.

Amy: "Shhh…..its okay, baby its okay."

Sheldon: "But I…."

Amy: "Shhh…just let go."

She wraps her legs around his legs to keep from falling off him. Sheldon finally can't help but to rock his hips back against her unable to resist the intense pleasure anymore he shuts his eyes too scared and excited to look anymore.

Amy rolls her hips faster and faster and within seconds Sheldon explodes and shouts out a ton of scientific gibberish and equations when he comes. He spasms and ticks uncontrollably. Amy smiles as she watches him then she kisses his chest so happy that she was able to make coitus finally happen for them.

After a few more gentle kisses on his neck, chest and shoulders she moves off his sweaty body to relax and pulls the sheets up to cover herself. Amy lets Sheldon calm down a little more then she snuggles up to him when he finally reopens his eyes his breathing still ragged. He looks into her warm comforting tea eyes totally amazed by everything that just happened between them and feeling happier than he's felt in a very long time. Sheldon can barely think at all, but after a few more silent moments he manages to finally speak to her again.

Sheldon: "Nemaiyo."

Amy stares at him confused by his strange word.

Amy: "Huh?"

Sheldon: "Its Vulcan, it means thank you."

She stares into his eyes for a second longer then Amy grins.

Amy: "I see. Well then, Qay'be."

Sheldon blinks his eyes in awe as she smirks at him. He can't even believe Amy has actually learned how to say "You're Welcome in Klingon. He is so ecstatic that she is finally starting to appreciate Star Trek that he kisses her.

Sheldon: "So was I aloof, yet satisfying enough for you?"

Amy: "Oh yes, I said so. I even propose that we do this experiment again soon."

Sheldon: "Very well, I'll accept your proposal. But, right now I feel sleepy."

Amy nods her head then gently kisses his forehead as she lets Sheldon lay his head down on her chest so he can rest while enjoying the sex induced mix of chemicals and endorphins running through his brain. Sheldon yawns softly with exhaustion as he closes his eyes ready to sleep.

Sheldon: "Goodnight, Amy."

Amy smiles as she also closes her eyes too and squeezes him close in her arms.

Amy: "Goodnight Cuddles."

The End.
