For science (Mature Version)

Twilight was reading in the library as I returned. "Hey my love.", she said. "Spike told me you were out for your talk with Dashie."

I sat down in a chair opposite of her and decided to leave certain parts out of my story. "She gave me a lot of stuff to think about. I hadn't expected she could be this serious and to give that good advice."

"What did she tell you?", she asked.

"Well, in short... to concentrate on what I can do, instead of thinking about the things I have lost. She has motivated me to think about my situation in a more positive way."

She laid her book on the table next to her. "I'm impressed what a good influence she can be... when she wants to."

"I think I know what I want to do with my time here.", I told her. "But I need a bit more information first."

She leaned forward. "Okay, ask away."

I looked into all the kinds of books here in the library. There are a lot about 'regular' stuff, quite a lot about magic and a few about physics, but I haven't found a single one about chemistry. Don't you have chemistry here?"

"I'm not sure what you mean by this.", she answered confused.

"Well chemistry tells us what things are made of.", I tried to explain.

"Oh, you mean like an apple containing about 80% water?"

"No, I mean what is the water made of?"

She looked at me like I had gone mad. "It water... It is 100% water."

"I guess with all the things magic can do, you never needed chemistry. What if I told you water is made of two things... two elements, one is very flammable, and the other is necessary for anything to burn."

"Water... can burn? I don't think that makes much sense.", she told me.

I thought a moment about what to say next. "You told me you have electricity, right?"

She nodded. "We use it in the big cities mostly for lighting, in other places like here in Ponyville we still use oil lamps for this."

"If I could get some device here that produces electricity, I can prove it to you because there is a way to separate these elements. Of course, things could work different here in Equestria."

She stood up and came close to me, her face only inches away from mine. "You... are saying my... my beautiful marefriend could bring us a whole new kind of science?!"

"You could say it that way.", I confirmed. "...Twilight?" She seemed to be totally spaced out.

*Drip*

*Drip*

"Twilight? Twilight, I think something is leaking."

*Drip*

*Drip*

Her eyes focus on me again. "I need you... in bed right now.", she said with a growl. "I promise, I try to be careful about your arm, I put a forcefield around it, or something..." *Drip* "BUT I NEED YOU RIGHT NOW!"

I was surprised by this announcement. I just nodded, and moments later she dragged me up the stairs into her bedroom.

She put up that soundproof bubble we talked about, then she pushed me onto the bed and started to undress me in record time by using her magic. As she had problems with my bra, I wanted to explain it to her, but she just ripped it apart.
She stared at my bare breasts, her mouth slowly inching closer until I felt her hard breathing against my already erect nipple. When her lips finally touched it, and she softly sucked on it, I felt incredible lust and horniness echo through our connection. We both moaned loud and deep while she used her hoof to caress my other breast. After a moment she lifted her head. "I want to see it all.", she said. "And taste it."

"I won't stop you, honey.", I whispered. With a big smile she slowly went down my body, she used her wide rough tongue to play with my belly button while she never took her hooves off my breasts. She gave my belly a last kiss and traced her tongue even lower down my body. She had to take her hooves off my breasts in this process, but they found a new home pressing against my butt cheeks.
Finally her tongue pressed through the already moist slip, against my pussy lips. A deep animal like growl escaped my mouth and both our bodies shivered from the wave of pure sexual energy rumbling through us.
Her hooves grabbed both sides of my slip and slowly dragged it down to give her eager tongue access to my most hidden place. She licked my trimmed pubic hair and buried her wide tongue deep inside my pussy. I grabbed her mane while pure pleasure rushed through my body. I felt my juices flow down inside her mouth and she drank them oh so eager.

"Please, I want to taste you too!", I screamed.

She started to move her body into 69 position while she never took her tongue and mouth from my pussy.

As she finally was within my reach, I used my thumb and index finger to spread her wide open before me. I smelled her unique scent that I loved so much, only ten times stronger. Drunk from her scent and her constant slurping of my juices, I stuck my tongue deep inside her and explored every part of her insides. She let out a muffled scream inside my pulsating pussy while I used my hand to caress her petite udders and her hard nipples.

I felt myself getting closer to the climax from her muscular wide rough tongue, so I decided to even the odds by sticking three of my fingers inside her and started to finger fuck her in a fast and deep rhythm.
She threw her head back and screamed in incredible volume: "SWEET CELESTIA, DON'T STOP DOING THIS!" Then she buried her muzzle inside me again while I additionally use my tongue to caress her clit. We had lasted maybe another minute or two like this before I felt her walls pulsing against my fingers as she finally came. Since I was already close myself, her orgasm flowing through our connection as well as towards my waiting mouth was more than enough to push me over as well. I slid out my fingers and pushed my mouth against her. We both filled our eagerly waiting mouths and drank it like the last drop of water in a dessert. I felt dizzy, horny, happy and whole at once and I knew we shared that feeling.

We laid next to each other, breathing heavy, our faces sticky and our bodies sweating. She used her magic to let the magic bubble disappear, without it, I guessed even Canterlot would have heard her screams.

"I love every single spot of your body.", I told her smiling. "And you taste delicious." I licked my fingers.

"The same is true for you.", she said and sighed pleased.

I pulled her close to me, and we shared a long kiss that mixed our juices. "How about sharing a hot bath?", I asked her. "I would like to clean you... everywhere."

"I think this is a great idea. I would like to give your udders a bit more attention as well."

"You know, we call them breasts in my world."

"Breasts or udders, I can understand why Dashie is so into them.", she told me and caressed them softly.
I was lucky she was concentrated on my breasts and didn't saw my face while she said that, or else she could have noticed...
"Mmmhhhh... but we should be careful going to the bathroom, I don't think Spike should see us like this.", I said smiling.

"I got this." She used her magic to open the door a bit. "Spike, please go and tell Rarity we will visit her tomorrow.", she shouted. "Stella needs new clothing. You can take some bits and get yourself ice cream afterwards!"

We heard happy sounds from the ground floor and the front door after some seconds.

She grinned. "This will keep him occupied for quite some time."

We went down to the bathroom and started to fill the bathtub.

...

After some more wild kisses and rubbing our sticky pussies against each other before we started to clean them, I laid in the bathtub very relaxed. Twilight's back was against my belly, her head between my breasts and I had put my arm around her.

"I don't think I ever felt so relaxed as in this moment.", she said with a happy sigh.

"I think I would like to build a little lab behind the library, to see if chemistry works the same way in Equestria.", I told her. "Do you think this would be okay?"

"You could use my lab in the cellar, I tried to analyze Pinkie Pies 'Pinkie Sense' down there maybe a month ago. There is even a little electric generator I used to power the analyzer."

"You tried to make sense of Pinkie's behavior?", I asked smiling.

"In particular her Pinkie Sense, it gives her accurate visions of the near future. But I found that 'Pinkius Pieicus' doesn't make sense."

I laughed at that. "I rather have my own lab since I don't know if things react the way the would on earth, I don't want to burn down the library."

"Well, that makes sense. You should ask Applejack to help you build it. She is great at building stuff."

"I will ask her later." I traced my hand down her body. "But let's enjoy the bath a little longer."

She turned her head to kiss me and muffled moans echoed from the bathroom walls as I buried my fingers deep inside her lovely pussy.
