Cookies and a Devil - the full story

Back with Artyom and lucy. "Oh, I nearly forgot. Lucy, there is a bag behind the bed that might interest you"
"A bag? Do you mean the powder?" She giggled.
"Maybe..." he said and thought of the necklace with the gems...
"Well, whatever you wanna do tonight is okay. I'm yours and my body is your property", she said snuggling up to him.
He licked his lips, "well then, find it for me, lucy" he petted her mane, "or pet ?"
As he said pet she nearly moaned a bit. Then she rushed through the room to try and find that bag. She actually remembered that he left the bag of powder on the kitchen table. So it couldn't be that. "Hm, what would he have left behind there?" She tried to find it. If he would walk in right now he could see her butt looking right at him. Her tail raised in excitement.
He watched the show with a bit of amusement and eagerness, he did not interrupt her in her search.
"You nearly have it!"

Her hooves touched something invisible. "But if it's invisible... ", she blushed, " ... I don't recall you buying anything else from their shop instead of the powder." She turned around holding it for him. "Well if it's a surprise tell me to cover my eyes", she smiled.
Artyom lifted the spell off the bag. It was a plain shopping bag, "I wanna see you opening it up"
She did put it on the table and then opened it up. "This is...", she blushed deeply. She looked a bit shy. "D do you want me to put it on?", she asked.
"Yes." That yes was a command, "but i let you decide which gem you put in"
She wrapped it around her neck and looked at him. "I... don't wanna decide. It kind of takes the fun out of it. I'm having this on, because I want you to control me ... master."
"Very well then, pet. I have not seen what the red one does so put that in," he said. Annoyed that she did not accept his kindness.

Lucy took the red crystal and clipped it onto the collar. Suddenly her face was filled with lust and as the crystal started to glow she played herself down before him and spread her legs to show him what happened. Her Gender swapped and it was a very pleasurable process. She moaned and as she got her dick it was already rock hard.

Now what do you say about that?", she smirked. "How about I rut your from behind stud? Or do you wanna sit on top of me?

"Now that was unexpected" Artyom stared at the cock. " the first option sounds nice. Lets get it to use then" he got on the bed as well and got into a sub position
"Take me like your uncle did"
"Such a good boy, so eager to try new things. I think this thing makes me also a bit more dominant. Well how about that." She used her magic to get something from the drawer. "Let's lube you up nice and wet, we don't want it to hurt too much."

Slowly Lucy poured lube all over her shaft and Artyom's rear. "There you go, now relax." She leaned over him and softly bit his ear to get him to feel good and relax a bit.
"Mm lucy... show me what i did to you all those times"
She did it very carefully. First prodding against his rear than probing him softly. Then she used a little bit more force. "Mhh, even just putting the tip in a bit feels nice. Now are you ready for a bit more stud?"
"Only with you"
"Good boy", she said and let her new horsecock slowly and carefully glide into him. "Just a few deep thrusts and you'll start to love it I promise." She was so deep in him that she wondered if she did hit his prostate and with that his G spot.

"Uhgn you're a tight bitch. It feels so good to take you. Tell me when you want it faster, slut", she said as she carefully bit his neck.
"FASTER" just a millisecond after she bit his neck
"don't hold back, I am tough"
She loved his voice when she dominated him. "What a cute voice", she said thrusting a lot harder and faster. "How's that, slut?", she said hoping deep inside, that he's okay with that wording.
He moaned into his pillow as a reply
"Maybe you'll even like it when I do this!", she gave him a slap on his right and left buttcheek. "Such a good boy. Let me do something for you too." She leaned completely on him and took her right forehoof to massage his dick, while her shaft penetrated him deeper and deeper with each thrust till it was fully submerged in his rear.
"Yessss~~"
"Cum with me!", she demanded and he could feel her starting to pulsate. "I'm close your tight fuckhole is so good, I want to fill it up with my stallion spunk!"
"Oh, my love. Anything for you and your glorious cock!" Artyom was leaking and ready to shoot directly into his face

She took him even harder and enjoyed the view as she reached her limit and couldn't hold back anymore. With a few more hard thrusts she released her shots deep inside of Artyom. "Cum for me, pet", she said and continued stroking him until he released all that tasty seed.

Artyom and came in command of his mistress. He shot many ropes of hot cum on the sheets and on his face, feeling the warmth of lucy inside him.
"Good boy release all that pressure." Then as she was finished with him her dick got a bit softer and was pushed out by his rear pulsating. "That was amazing", she said panting and breathing heavily.
"Ha ha hah.. yeah. You can compare it now. Whats better, a male orgasm or a female one?"
Artyom got his strength back and sat up.
"They're both unique", she said. "It feels completely different. A male orgasm is very strong and deep and a female orgasm is mind-melting and weakening. Maybe you should try it sometime", she grinned.
"Ha ha ha.. not today, love. Now get that crystal out. There's is one more of we have not tested yet," he pointed at the... green one?

"W... well that one I'm honest... it's kind of embarrassing. So don't laugh okay?", she said a bit shy. "And before I use that crystal let me go to the bathroom real quick. I know it's not the best sentence to say while in this mood, but trust me it's necessary." She ran into the bathroom and came back real quick looking not really different. Her face was deep red. You could see that it was one of the most embarrassing moments of her life. "T... this ... I ... only for you." Before he could answer anything she clipped the green crystal onto the collar and laid herself in front of Artyom cuddling against him as the crystal started to glow and her thoughts began to slow down.

She looked really confused. "A... Artyom how old am I again?", she asked with an empty look on her face.
"Hmmm not sure" he moved over her to get a better look. She was so young and wide hips. "You look like with extremely wide hips. Not sure if you can take all of me like that but we can try..."
He nuzzled her from behind
"Who is daddy's girl?"

"I.. Me? Me! I am!", she smiled and hugged Artyom. "Take what daddy?", she asked.
"A tickle attack!" He tickled Her
"Nooo", she laughed and rolled onto her back panting a bit. "Daddy, I don't know why, but I feel tingly there", she pointed right at her clit. "It feels weird, I'm scared daddy", she looked like she was about to cry.
"Shoo. don't cry." He nuzzled her, "i kiss the mean booboo away, okay?" He smiled and kissed her winking clit
"I ... daddy, what are you doing? It's dirty down there!" Then the pleasure hit her mature body giving her immature mind nearly an overload, because she couldn't process it. "W what is that t that feels good. Lucy is feeling good, daddy." Her body reacted normally, but it seemed like her mind just couldn't. She couldn't get her head around what was happening, but somehow she liked it.
He continued to lick it
She started to pant a little as her arousal started building up.
He looked up, "do you like it?"
"Lucy likes", she said clearly overwhelmed by her feelings at the moment.
He grinned and popped up, "can I show you something ?"
"What is it, daddy?" She looked very interested. Maybe he was going to do more magic tricks to her body that she didn't know about.
He grinned and sat in front of her, his dick out.
"Daddy was your weewee always this big?", she asked.
"Because it is excited to see~~," he said and leaned forward, aiming for anal sex

Lucy tensed up. "Daddy, what are you doing!", she looked scared.
"Trust me," he said and probed her entrance
The collar glowed and Lucy's fear turned into a smile. "Yes, Daddy", she said relaxing her whole body.
He went right in
The collar kept Lucy from tensing up again as it did hurt a bit that he was going in without lube. But then the pain changed. The now little mare again couldn't get her head around why this started to feel so good, but she didn't want daddy to stop. "I is that another magic trick daddy? It should hurt, but it feels good again."
"It is, baby," he said and pounded a bit harder.
She moaned loudly and as the collar glew again she looked a bit worried, but at the same time very aroused. "Daddy, it's coming out! Something's coming!"
"It's.. fine."
Again the crystal lighted up and Lucy rolled her eyes, as her "first" orgasm hit her hard. Normally she would have held back a bit. But this time there was no knowledge of what her body was doing, there was no way she could possibly hold back anything. With the next thrust he did she squirted like she never did before, it dripped onto his cock lubing it up and drenched his belly fur in her juices. While she squirted her anal muscles were pulsing, squeezing pretty hard on Artyom's shaft.
"Good girl. You did fine" he said and with a grunt came too. His cum coated her inner walls white as fuck
"Ah it's coming out of daddy, too ... ", she moaned, " ... daddy feels good too. Lucy happy!"
Then she started to cry a little. This was all too much for her.
He sighed and pulled out from her, "you did well, lucy." He petted her and removed the crystal
As the crystal lost connection with her, she sobbed instead of crying for a moment, then she looked away. "Kiss me", she whispered.
Artyom leaned forward and grabbed her neck, his lips connecting with hers in the next moment

The kiss washed all her tension and embarrassment right away and her whole body relaxed. She put her arms around him and rolled him to his side cuddling up against him. "I love you", she whispered looking deep into his eyes and then she sat up. "Here I want to... show you something." She sat right in front of him as she touched a few places on her body. Then she asked him to not touch any of the stuff that would appear in a second. As she touched the last place Symbols, Runes and Sigils started to appear all over her body.
"Oh... my "

She looked a bit embarrassed. "These are the runes that allow me to use magic. As you know I'm an earth pony. I shouldn't be able to, but runes allow me to use magic. I won't explain the whole process, but look here, ... ", she pointed to a rune, " ... this one keeps me from taking damage falling." She pointed to another place on her legs. This time the sigil was on each of her legs. "This one enhances my speed. And ... ", now her face turned deep red, " ... this one." She was pointing a few centimeteres above her clit. "This one ... keeps me from getting pregnant", she touched it and looked at Artyom as she did. "I love you", she said once again as she lifted her hoof and the rune was gone. "I know you can determine if you're fertile or not. I want you to be sure you want this as well, but just ... I'm sure I would want it." She was so overwhelmed by her feelings, that she nearly started to cry again, her eyes got a bit wet, but she could hold back from actually doing it. The runes started to slowly fade again and she smiled hoping that he would be okay with her decision.
He had no words
She came a bit closer "I'm sorry if this is so sudden. We don't have to do this right now it just felt like the right time to tell you."
"But we already talked about this, baby" he kissed her again, "after a few jobs in Tartarus and we make that foal reality, okay?"
"You don't have to plan it if you don't want to if you want we can just let it happen", she smiled and gave him a passionate kiss.
He returned it gladly but then said, " a foal now would just complicate things, dear."
"I just wanted to show you this", she pointed to the place where the rune was. "Everything else is for you to decide. It's like I said, I'm yours." With that she snuggled up to him and closed her eyes.
He sighed happily and did the same

She had packed up all her things, she thought she would need. "If I need anything else. I'm sure I'll get it somehow", she smiled and looked at Artyom. "Well, I think I'm ready to go."

"Did you say good bye to the others too?"
"Family and stuff"
"Well if they ever wanna visit me they would just have to come and say hi. But yeah Nevio was so kind to change my money into your currency, what was it again?", she asked. Then she smiled. "Well, these guys here are my family."
"We have bytes or euros. Alright then. 6 months in Tartarus then. Hmm. Oh, the carriage back home arrived!" He said and ran out.

Lucy put on her bag and followed Artyom.

Outside from the building, there was a carriage, average looking. With a mare leaning against it, she looked like a mirror version of Artyom except being a bit brighter and her cutie mark being a skull with wheels. Artyom looked a bit thoughtful as he saw her but shook his head, "good day, devil. You here to get us back home?" The hidden devil nodded and looked at their packages
Lucy didn't have much except for her bags. >They look an awful lot like twins<, she thought. >Why did she choose this appearance? Maybe it's just an coincedence<, she internally shrugged it off and stepped right beside Artyom.
"Do you need assistance, madam?" Asked the hidden devil.
With a monotone voice
"I have just my bags and this briefcase. If it's okay I'll keep my bags with me, but the briefcase can be stored away." It was a big briefcase nearly anything could've been in there.
The door to the inside opened and the mare nodded. Taking the briefcase and disappearing on the other side of the carriage. Artyom chuckled at the antics of the young devil and stood beside the door, "ladies first"
She got in but as she was between inside and outside she cheekily said. "The first ones will be the last!", and then she quickly got in.
"Huh?" Artyom was confused but followed anyway. The inside was like any other carriage but with red leather seats and red walls. There was not much else to note except the rabbit head emblem on both windows and yellow seams in the walls.

The devil seated himself on one side

Lucy looked around. Then she lay down on the other side stretching over the whole seat. "Uhhh comfy", she said and smiled.
The devil mare outside got back to the riders bench and looked inside, "ready to depart, master Artyom?" The older devil nodded
"I just realized, that you said you live in another dimension. So are we going through a portal?"
Artyom shrugged and the carriage started moving somehow.
"You always black out before.. *yawn*"
She thought her runes could protect her from that, but it seemed that wasn't a normal forced blackout. It was more like there wasn't anything to see or hear or think the moment you switched the dimensions. "But how does the coach driver drive the carri~", she tried to say, before everything went black.
