A Sexy Twily Weekend!

Prelude: About Me

It had been two years since I moved to Ponyville and while things seemed rather mundane, I did attend the various festivals they held. The first exciting event that happened was when Nightmare Moon returned and cast Equestria into a state of eternal darkness. I was a bit concerned over this because the idea of no daylight did not sound appealing to me at all. Luckily the protege of Princess Celestia, Twilight Sparkle, and her friends were able to reform Princess Luna and restored the normal day/night cycle.

I decided to attend the festival they held for Princess Luna's reformation and at it I bumped into Twilight. I remember that moment, I felt a bit embarrassed when we fell over one another. Naturally I helped the larger pony up and apologized and she gave me the cutest smile. I didn't think much about it at first but after that Twilight did start dropping by my house every now and then, without her assistant present. I wasn't sure why at first but then I figured it was because she was curious about human culture and human nature. One thing that was good was that she didn't bring Spike with her. Yes Spike is nice and all but there are some things about human nature that should not be discussed around children.

An Evening Visit By Twilight

Another week had drawn to a close and the good thing was that the following Monday was a holiday in Ponyville since the Sisterhooves Social was a huge event. Once I got home I decided that I was going to fix myself a larger than normal meal like I always did on Friday evenings. One thing I wished I had were hamburgers because that was always one of my favorite things but luckily the hay burgers that the ponies eat aren't half bad. They do make a decent substitute after all, as does the other hay versions of the meat I ate back home.

After eating my supper, I decided I would head to my bedroom and read a Daring Do book that Twilight had loaned me. When I headed towards my bedroom I noticed that my light was on. That was strange because I never leave any lights on when I leave my house but hey, maybe I forgot to turn it off before leaving. Everyone makes mistakes after all.

When I got to my bedroom I noticed something I certainly didn't expect. In on my bed was Twilight Sparkle laying on my bed, facing the door with a very seductive look on her face. I was kind of shocked that she would just go into my house like that but what really shocked me was the looks she was given me. I saw those beautiful purple eyes of hers, gazing at me with a look of hunger, a look of lust. I gave her a nervous smile, "Uh hi Twilight. I didn't expect to see you here!"

When I first arrived, she was wearing a sexy outfit but once she got up, she removed it, turned around and wiggled her flank before approaching me. She gave me a smile, "You know Luke, it isn't very nice to eat supper without coming to get your guest first."

I replied, "I didn't even know you were up here Twilight!"

She continued to approach me and said, "Well I suppose I will forgive you IF you will do a few things for me." She gave me a smile and suggested, "How about you undress and lay down on your bed." I had a nervous look on my face as she added, "You do want me to forgive you, don't you?"

I replied, "Of course I do, I don't want you to be upset with me!"

I wasn't sure exactly what to think about Twilight wanting me to get undressed for her but then I figured that maybe she wanted to do research on a human's body and figured I'd be the one who would be open to it.

Twily Kissy Kissy Time!

Once I had got fully undressed and laid down on my bed, Twilight walked up to me and took a good look at me. The very first thing she looked at was my penis. She shook her head and sighed, "I knew that human males were smaller down there than stallions were but" she paused before adding, "you know, I want my first time to be full of pleasure and you can't please me with this!"

She then flared her horn up and cast a spell, causing my penis to grow in length, causing it to grown in circumference and caused my testicles to grow in size too. This shocked me and caused me to wonder one thing. I asked her, "Twilight, are you wanting us to have sex?"

Twilight giggled, "Not yet Luke, not yet. It might be tonight or it might be later but trust me, you will be my first." She paused, crawled up on top of me and asked, "Luke, will I be your first, your last and your only?"

Twilight was quite a bit bigger than me so her weight on top of me was rather uncomfortable but I did have a feeling she'd like my response, "Twilight, I have never done what you are asking about so yes, I'll be your first."

She clapped her hooves and cheered, "Yes, now I know you are clean but before we share each other, there are so many things I want!"

Twilight immediately leaned down, wrapped her hooves around me and pulled me into a passionate kiss. Her much larger tongue quickly forced its way into my mouth and her saliva began to flood into my mouth. I then wrapped my arms around her and began to stroke my fingers through her mane. The feeling of Twilight on top of me was nice, very nice. I always thought that the ponies would have a coarse coat but Twilight's coat was silky soft and her mane had the same texture as that of a human woman.

It wasn't long after we started our kiss that we began to moan gently into one another's mouth. As our kiss continued, Twilight began to wrap herself much more tightly around me. She then briefly broke the kiss and asked, "Do you like your best friend kissing you Luke? Do you like our kissy kissy time?"

I was already feeling so much pleasure that all I could respond was, "Mhmm!"

She cheered, "That is wonderful Luke, I'm so happy you like it!"

Twilight then pulled me back into the kiss and started sucking on my face even harder. It truly was a wonderful feeling, especially with her massive tongue invading my mouth and her saliva flooding it so that I could swallow it. She could tell that I was swallowing it and continued to moan gently into my mouth. I wasn't sure how long our kiss lasted but I did know that it was a very long time. When she finally broke the kiss I exclaimed, "Oh Twilight, that felt amazing! I could kiss you for hours and hours on end!"

Twilight giggled, "You know, I'll remember that and next time, I might hold you down like this for longer!"

I gave her a smile, "And I would love that!"

She cheered, "Alright but now, on to what I want next." She rolled onto her side and lifted a leg up, "I know humans like this so you probably know what I want!"

Twily-Twi 69 Time!

After she laid down and raised her leg, I laid my head at the very top of her leg, to where my cheek was in between her legs so my mouth would be in the right place. She giggled, "Good boy Luke, you know what you have to do with a pony! I certainly can't cum if you aren't eating me!"

She then wrapped her legs tightly around my head, forcing my mouth to where it was right over her pussy. I then took to it just as she shoved my cock into her mouth. Oh my goodness I never imagined that any experience could be so wonderful. Twilight tasted so good and the smell of her was wonderful. The feeling of her tongue massaging my cock along with her saliva being her lubricant made it feel like I was imprisoned in a hot and wet slice of heaven.

We both were giving off muffled moans of pleasure as we were tasting one another. It wasn't too long though until the two of us began to moan louder and wrap our legs more tightly around the other's head. Our breathing continued to get heavier but then all of a sudden, the climax I felt coming wasn't but she moaned loudly as she flooded my mouth full of her cum and sweet Celestia, it was so tasty and intoxicating. As I was drinking it, I found myself wanting more and more.

With my climax suddenly being delayed, I had a feeling that she had likely cast a spell to delay it, which was something that I was completely ok with. As we continued to eat one another, she continued to have orgasm after orgasm, providing me with more and more of her cum. She seemed to provide me with a lot of cum and the more of it I drank, the more I not only wanted it but wanted her too. Finally after what had to have been even longer than our kiss lasted, I finally felt my orgasm coming.

I moaned loudly as I began to flood her mouth full of my cum, cum that I could tell that she was swallowing. After she had milked me for all I was worth, she released her hold on me and we separated. Both of us were breathing heavily and I exclaimed, "Oh my goodness Twily, that was like a pure slice of heaven! I never knew such pleasure existed."

Twilight giggled, "Just wait Luke, if you thought that was great it won't be long until we take our friendship to an even deeper level!"

I gave her a smile, "Oh I'm sure I'm going to love it!"

Backdoor Sexy Twily Time!

After we finished eating one another Twilight got off the bed and prompted for me to do the same. As we got up I noticed she was twitching her tail back and forth rather quickly. I gave her a smile and asked, "Is somepony getting antsy, is somepony getting needy?"

Twilight giggled, "Mhmm! My ass is hungry and it needs your cock!" She approached me, leaned down and kissed my member before adding, "And I can sense it, I know your cock wants my ass so badly!"

Anal sex was actually something that I had never even thought about before, especially with Twilight once we started hanging out more. This was Twilight however and I'll admit, I had developed a crush on her as time passed on. I gave her a smile, "If your ass wants my cock, my cock is what it shall receive!"

Twilight giggled, "Good but I want you to pound me, I want you to ram me hard, I want you to rock my world!"

I gave her a quick kiss before replying, "Oh I plan on it!"

I stood behind Twilight and she quickly lifted her tail, granting me entry into her needy hole. The moment I shoved my member into her, we both let out gasps of delight. I then got to work on her, giving her exactly what she wanted. We soon began to moan loudly and the feelings I was experiencing at the moment were more than anything else I ever had. Her walls were so hot, wet and tight. As I was giving it to her, I began to feel so much more than just friendship with her. I began to want benefits with her and I certainly hoped she wanted the same.

As I continued to work on her she began to moan, "Oh yes Luke yes! Pound me, rock me, take me, fill me up!" She then began to moan louder and breathe heavier and I knew what that meant, I knew that she was about to climax but I certainly couldn't just allow all that wonderful cum of hers to hit the floor so I put my knee up so that she could cover it instead.

Soon I began to moan louder too and my breathing became heavier and like she had before, she flared up her horn and cast a spell to delay my orgasm. As she did this she let out a loud moan, "Oh Luke baby, yes yes!" as she climaxed and soaked my knee with her lovely cum. While she had climaxed, I had yet to do so so I continued to pound her harder and harder as she demanded it. It seemed like the longer and harder I pounded her, her ass began to grip my cock harder and harder.

After what seemed to be not as long as our other activities I saw her flare up her horn and cast another spell and almost immediately I began to feel it coming and not long after that, I began to flood her ass with my cum. Once I had given her everything I had, I pulled out and said, "Twilight, that felt amazing. It wasn't as long but still, it was wonderful."

She turned around and giggled, "Oh just wait, what I have planned for us next will make everything else feel tame!" She approached me and gave me a kiss before adding, "And I know what it is you want, it is just what I want and with my magic, I can keep us connected for hours and hours on end!" She then giggled, "Maybe even longer, I could make it days if I wanted to!"

I gave her a smile as I could only imagine what that would be like. I knew what was coming up and the very idea of having sex with her for hours on end and maybe even days on end excited me a lot. The very thoughts of her pussy having a tight hold on my cock was something I could hardly wait for.

Pussy/Cock Love Twily Time!

It was probably ten minutes after we had finished our anal loving session when she gave me a smile, "Are you ready Luke? Are you ready to give my pussy your cock?"

I replied, "You bet I am Twily!"

She approached me, swatted me in the face with her tail before getting down a bit lower and raising her tail. She then demanded, "Now fuck me Luke, fuck my brains out, fill my needy uterus full of your seed, make me feel like a queen!"

I approached her and gave her a smile, "My my, so demanding!" I will admit, I found her sudden demanding attitude very attractive and I added, "If you want me to fuck your brains out, I'm going to do it and when I pop your cherry, you're gonna love it!"

She yelled, "Get to it stud, fuck me and fuck me good!"

I loved her sudden dominant nature and then the time had come to give her the rough sex she seemed to want so badly. I lined my cock up with her pussy and shoved it in and very quickly I felt a barrier that was easily penetrated. Twilight let out a loud scream, "Ugh, that hurt Luke, that hurt!"

I yelled, "Twilight, you wanted this, you wanted it rough!"

She yelled back, "I did and now, get back to it! Do it and I have a special spell for us!"

I began to wonder what she meant by 'for us' but I knew how I could give her the rough sex she desired. I leaned forward, wrapped my arms around her and then locked our legs together, making any kind of escape for her impossible as I began to thrust her hard. Very quickly both of us began moaning our names out loudly and scream as I got rougher and rougher with her.

Soon I saw her flare her horn up and cast a spell. Very quickly our nether regions began to grow together and ultimately, her walls began to envelope and imprison my cock. Once we had fully grown together her voice became more calm as she moaned, "Luke, we're one now! Be gentle!"

I slowed down the rate at which I was thrusting her and all of a sudden the pleasure I was feeling was unfathomable. I began to feel shock waves of warmth flowing throughout my body as I began to moan, "Oh Twily baby, yes, yes yes!"

Twilight was giving off gentle moans, "Oh yes Luke yes, make us happy, keep us together!"

I continued to thrust her gently as it was obvious that it was making her just has happy as it was me. I knew this spell was special because while we both felt our climaxes coming, neither one of us could reach it. I kept myself wrapped around her gently rocking her and the more I rocked her, the more she moaned, "Mmmm oh Luke, mmmm oh Luke!"

I was moaning out her name gently as we continued what had started out as rough sex and turned into an intimate love making session. I continued to rock her gently and as I saw the sun beginning to rise, I felt my head beginning to swim and then it was coming. Stronger shock waves began to surge through me as I moaned, "Oh Twily baby, yes baby yessssss!"

I then began to release rope after rope of semen into her. My head continued to swim as I kept on filling her up. I'm not sure what was going on but it was like I just couldn't stop. Finally I heard Twilight yell, "Luke I'm full! My uterus is full!"

She then flared up her horn and cast a spell that caused our nether regions to part so I released my hold on her and collapsed on my back. That long session of filling her had worn me out and she leaned over me and giggled, "Good thing humans can't get ponies pregnant or I'd be having your babies!"

I gave her a smile, "And we couldn't continue to explore our friendship non-stop forever!"

Twilight crawled on top of me and giggled, "Mhmm! I can tell you're tired and I'm tired too. How about we go to bed for a while and after we get some sleep, we can do this all over again," she paused before adding, "and then some!"

When she said "and then some" I really liked the sounds of that. I gave her a smile, "And then some huh? It sounds exciting."

Twilight giggled, "Exciting?" She paused before changing her mind, "Forget getting some sleep for right now! There is one more thing my ass desires and I know you want to please her! Now get laid down!"

I wasn't sure what this was going to be about but with her wanting me to lay down, I knew that it most likely was not another session of anal. One part of me dreaded it but another part of me, the part of me who wanted to please Twilight was looking forward to it.

Tasty Hole Twily Time!

After having the most pleasurable experience I could ever imagine with Twilight, she ordered me to lay down on my bed for one more thing. Once I got laid down she crawled up on the bed and giggled, "Are you ready for this Luke, are you ready for another tasty treat?"

I gave her a nervous smile as I knew what her plan was and then she clapped her hooves and cheered, "Of course you are! I know you want to taste your best friend everywhere!"

She then crawled to where her cheeks were right above my face and started to lower them. She then sat down and began to grind her cheeks against my face in an attempt to consume it. She yelled, "Luke, lick me, probe me!"

I attempted to but the most I could do was make a tiny bit of contact with her hole. Then I heard her sigh, "How could I forget, my buns have to embrace your face!" She began to giggle as she obviously cast a spell to enlarge the size of her cheeks to grow and ultimately envelope my whole head, pushing it to where my mouth was pressed up against her hole. She then ordered, "Eat me Luke, suck me, eat my ass!"

Given that her ass didn't smell like what I thought it would I began to suck on her and probe her and I could hardly believe it. Instead of tasting awful, she tasted like mint and I love mint! I immediately reached up and began to massage her cutie marks as I continued to eat her. She then began to moan, "Mmmmh, ooooh Luke! You love my ass don't you! Eat me, massage me, probe me!"

I continued to eat her and probe her as I massaged her and soon I began to feel a trickle of mint flavored liquid dripping out of her hole and into my mouth, liquid that I greedily swallowed. It seemed like the more of the liquid I consumed, the more I wanted to stay buried between her cheeks, the more I wanted to eat her ass. Soon she began to grind her cheeks up against my head again and soon she began to sweat, covering my face in it.

I then began to feel her sweat actually seeping into my skin, making me want more and more of her. By this point, the only thing running through my mind was Twilight, our special friendship and making her happy no matter what. I had completely lost track of time as my soul focus was eating Twilight's mint flavored ass and the future of our friendship. Nothing else mattered at that point.

I wasn't sure how long it had been when Twilight cast a spell to cause her buns to return to their normal size. She got up and gave me a huge smile, "You love my ass don't you?"

I was still in a bit of a daze as I replied, "Mhmm!"

Twilight pulled me up, pulled me into a kiss before replying, "My my, my ass does taste good!" She paused before giggling, "You know you ate it for 48 hours straight! You know it is Monday evening, right?"

I looked out the window and gasped, "It is? Sweet Celestia, I have to work tomorrow and I'm going to be so short on sleep!"

Twilight giggled, "You know, I can always get you a new job. I know Princess Celestia could get you a new job!" She kissed me before adding, "You could go from being personal banker at the credit union to being protege pleaser! Just imagine, us doing this all the time! I know you'd love it!"

I wasn't even sure if Princess Celestia would do such a thing and I decided to bring it up. "Twilight, I highly doubt Princess Celestia would do that. You have your duties as her protege and what if something was to come up where you had to save Equestria again?"

Twilight sighed in frustration, "Luke, Princess Celestia thinks of me as a daughter and if I want you as my sex slave, I know she'll give you to me!" She paused before adding, "Now do you want to be stuck working a nine to five job five days a week or would you rather give me the loving I desire and be able to eat my sexy minty ass whenever you want?"

I gave her a smile, "I'd much rather be with you Twilight. Being your sex slave is a dream come true for me and I'll admit, your ass is so tasty and having my head imprisoned by your cheeks is wonderful!"

Twilight clapped her hooves and cheered, "Well let's get showered, get some sleep and then go up to Canterlot tomorrow! I know Celestia will be so happy and who knows she might even force you to marry me! Wouldn't that be wonderful?"

I gave her a huge smile, "Oh yeah it would be. Being your sex slave and your husband, I am beyond ready for this but for now, how about we get showered and then get to bed?"

Twilight agreed and after we got showered, we crawled into bed together. Once we got under the covers the larger unicorn wrapped herself around me and gave me a few kisses before finally falling asleep. As I laid there being held tightly by her, I felt a sense of excitement. I could only imagine what my new life would be like, rather than working in a demanding job five days a week my new job would be giving Twilight the sex she wanted on demand and from the way she made it sound, eating plenty more of her sexy mint flavored ass.
