Author's Note

Now I know there will be some arguments about this topic, when in the human world if Sunset's dna becomes human or its still pony dna (pony in a human body), and this is my opinion about her dna in this series. About some of the information in this chapter they are researched.

Enjoy reading!

Light My Darkness

After hours of your shift, you patiently waited for Sunset outside the sushi restaurant. It wasn’t long she came out as the two of you walk out of Canterlot Mall. Before heading home, she did tell you early during both of your lunch break to call up Fluttershy and reserve two packs of hay and both of you will drop by the Animal Shelter or if it’s close to pick it up at her place.

Minutes of driving while Sunset clings behind you, the two of you arrive at the Animal Shelter. Both of you enter and see Fluttershy behind the counter greeting both of you.

“Hey Fluttershy,” Sunset said. “Do you remember what I asked for earlier?”

“Oh, yes Sunset.” Fluttershy handed over two packs of ‘Tasty Healthy Hay for Pets’ as Sunset pays for them.

“Sunset, your only pet is a gecko. What is that for?” You asked because Fluttershy doesn’t seem bothered about this. Then it hit you. “Ohhhh......Because you're a pony, of course.”

“See, you’re learning.” Sunset places a hand on your shoulder as the two of you exited the Animal Shelter. “But I only eat this kind of stuff back at the apartment, I mean it will be weird if I was found out eating something like this in public.”

“Point taken.” You started up your motorcycle as both of you drove back to your apartment.

“But seriously, a therapist?”

“You got a problem with that?”

“No, it’s just unlikely for you to become like that because of...well...your looks.”

“Saying goes: ‘Never judge a book by its cover’.”

“Fine, fine you win.”

****************************************************************************

Back at the apartment, you and Sunset are playing the dlc campaign of the Halo Wars 2 as the Banished. Both of you are at the final stage and just like last time…

“You heard him Dusk, shoot those fucking sacs and make that fucking thing bleed!” Sunset yelled over her mic.

“Words Sunset. Because from how you say that, it looks like we are actually hurting an animal.” You replied calmly as before.

“Don’t remind me about animal games. Because the last time I played a game like that, I lost to Fluttershy.”

“You mean the squirrel game?” You snorted after saying that. “If Fluttershy did hear our conversation, she is so going to get pissed.”

“SHUT UP! We’ve already made it this far and I don’t want to lose more units.”

Several stressful minutes passed (mostly for Sunset) after dealing with the final boss and hearing Sunset’s screaming due to the fact, she chose to play this in heroic, both of you finished the campaign. Before you remove your headset, Sunset invites you to her room for she ordered some pizza earlier for both of you which you accepted. Before heading down to her room, you decided to put on some pants than being in your shorts for sleeping.

You called out to her after knocking on her door. The door opened and there you see her but you couldn’t believe what you’re seeing. Her regular purple pajamas were a little bit short in some parts; her top which the sleeves are shorter and the length of her shirt exposes her midriff while the length of her bottom pajamas is up to her thighs. What triggers you the most is how fitting her clothes are.

“Well don’t just stand there, come on in.” Sunset grabs your hand and pulls you in only for your body to press against hers. You are now close to her face as things begin to heat up but what you caught a glimpse at is how her cleavage is expose. “Are you okay?”

“Oh-uh yes, of course.” You mentally slapped yourself back to reality as your body moves away from Sunset’s as she close the door. “Those pajamas?”

“Oh these, well I prefer to wear something more comfortable for the meantime.”

You doubt it. From the one she normally wears; these seem a bit ‘tight’ is the correct word. The smell of the pizza catches your nose as both of your stomachs begins to growl. The two of you sat on the table as Sunset opens the box and you got a slice. You asked her about the toppings since there are meat on it which she replies that she has gotten used to it already. After eating a few slices Sunset took out one of the packs of hay she got earlier from Fluttershy as she opened it up and began eating it. While at it she notices that you are staring at her.

“If you are somehow bothered that I am eating something like this.” Sunset said after taking another bite. “You can always look away.”

“Just getting used to it, that’s all.” You said consuming another slice.

After both of you are done, you offer to clean up as thanks for inviting you to her room. She accepts it and says that she will use the bathroom while you are doing that. The leftover pizza was placed in the fridge and the other pack of hay in the cupboard. While cleaning up the dishes you begin to have dirty thoughts about her tight pajamas again. You immediately shook your head quickly to snap yourself out of it,

“There is really no doubt she is comfortable wearing that and plotting something.” You thought as you placed the last plate in the dish dryer. Without you knowing from behind your mouth was covered by one hand while the other touches your erection which you forgot.

“There’s no use on playing pretend.” Sunset said seductively from behind as she presses her body and teasingly rubs her tits on your back earning muffled moans as she also gets a feel on your little guy. “I know you have been staring at me since I opened the door. About the part when I said these pajamas being comfortable, I lied. They seem pretty tight at first because the purpose of these...are for alluring you.”

She then breaks the hugs and quickly turns you making eye contact with her as she presses her body to yours again. This time her face slowly gets closer as you stood there and it wasn’t long like earlier, she filled the gap as you feel her lips press on yours. You gave in as you wrap your arms around Sunset’s body pulling her closer. You can feel her tongue touching your teeth trying to gain entry until she forces it inside to meet your tongue as she wraps her arms around your shoulders while wrapping a leg around yours pushing your body until it leans at the sink. Boldly you grab her thigh as you caress it earning moans from her as she now firmly presses her lips to yours. One simple kiss turned onto one hell of a wet make out session. After minutes of lust and ecstasy, both of you separate from the kiss but maintained your bodies pressed against each other.

“Uhhh...too much?” You said between breaths as you let go of her leg.

“Yes...but apparently...I kind of want us to do that again.” Sunset replies also gasping for air as she turns her attention to her bed.

You gave a simple nod as she led you straight towards her bed. You sat on it as Sunset tells you to wait for a moment. You see her locked her door, turned off all the lights except for her lamp at the desk next to her bed and closed the curtains.

“There, that’s better. Now back to where we left off.” You just watch from the bed as Sunset approaches you with a little sway of her hips. You were put in a trance as your eyes cannot leave hers as she pushes you to the bed. After she instructs to remove your pants leaving you in your shorts, she then straddles you becoming the dominant one here. What’s exciting and tempting you to go all out on her is while on top, her mounds are right in front of you as she playfully swings them. “You are staring again.”

“Sun-mmmmphh!?” Sunset lowers herself cutting you off as her tits are now pressing on your face while she rests her arms above your head for support.

“You don’t have to say another word, just enjoy what’s coming.” Sunset then lifts herself a little making sure her tits are still pressed against your face then lowers herself back down until she starts repeating the process. She can feel you nuzzling on them since you couldn’t help yourself until you wrap your arms around her preventing her from moving away as she feels your breathing underneath making her giggle.

You felt her covered nether regions touching your tented shaft as you feel your shorts becoming wet due to her grinding. Even though underneath the softness you manage to slip your mouth on one her nipples underneath her shirt as you start sucking on it making part of her shirt wet as Sunset bites her lip.

“Yes, oh my-fuck! You sure know what you are doing.” Sunset moans she continues with her grinding while you suck on her nipple. She lifts herself up only to fail for you won’t let go of her. “Babe, if you don’t mind?”

You didn’t have second thoughts as you remove your hands around her as she lowers herself as her tits rubs on you until she reaches your covered member. She tugs on your shorts lowering it until your dick springs out from underneath.

“Time for me to give this a good licking.” Sunset licks her lips until she presses her lips on the tip of your member. You shudder as she slowly lowers herself engulfing it. She lifts her head up leaving the head still inside her mouth until she begins to bob her head up and down. She then removes your dick from her mouth as she covers your entire length in her saliva then places it back in her mouth and it wasn’t long, she stopped. “I know a position where both of us can enjoy this even better.”

Sunset climbs back on top but then rotates herself and adjusts her position. Now her covered rear is facing you and you see a wet spot in the middle. She sways her rear in front of you and instructed to kindly remove her shorts. You grabbed on the hem and you slowly pull it down due to the tightness until it reaches her ankles and she kicks them away. As she lowers her now exposed wet pussy almost near your face, you felt her soft mounds pressing against your abdomen earning a surprised gasp from you.

“I remember Rarity doing something like this to Ardee after reading their mind last time, but in a different position. I can make it even better.” She seductively said as she starts to rub her tits on your shaft. After rubbing it a few times and the head is below you felt that its being inserted somehow inside her shirt until you felt your dick between her tits. “This is the benefit of this shirt and with the size of my mounds, I don’t need to use my hands to press them.”

Without putting much effort, she begins to move while your member is trapped between her breasts. Your moans increase since there is no man that can resist their manhood between a girl’s breasts. Not letting her have all the fun you grabbed on to her rear as you lowered her for your mouth to make contact with her pussy as you can smell her arousal. You start with licking her outer lips as you felt Sunset shudder to the feeling. After a while you inserted your tongue inside as you slurp her juices with you giving her butt cheeks a little squeeze making her gasp.

“Oh yes, mmmmmmmh. Keep eating me like that and Iet me now return the favor.” Sunset moans as she starts to blow you out again in addition to your dick being massaged between her tits. After minutes of both of you slurping and eating each other out, you can feel your pressure build up as you moved your mouth away from her dripping sex and warned her. “I want to taste your cum babe. I too am almost near.”

She then resumes her bobbing after giving the go signal. You also resume with eating her out until you unintentionally rubbed her clit with your tongue pushing her over the edge. Sunset came as you gulp down her juices which you also couldn’t hold it any longer. You release your cum as Sunset took it all. As the last of both of your cum subside you slumped down on her pillow while her wet pussy still hovers above you, but Sunset did the opposite. She used her hands and pressed her tits mashing your dick between them as you moaned in the process.

“S-Sunset...wait, I am... still sensitive.” You stutter between your moans. She didn’t listen and continued with her teasing until you felt another pressure build up. It wasn’t long you came again now covering her face and her cleavage with your cum as she slowly removes your dick between her breasts.

“Sorry about that. Just so you know I am in heat, so me jacking off is not enough.” Sunset then runs a finger on the cum that’s on her face as she licks it off while giving you her bedroom eyes. “Now I’ll just be right back, need to clean your cum off me before we start with the main event.” She then got up and head towards the bathroom.

Out of curiosity it came to your mind of her being in heat. You took out your phone from your pants that is on the floor and search for ‘horse in heat’. After turning your phone off and placed it on the desk, Sunset came back with her face and her cleavage cleaned up but still wearing that tight purple shirt.

“Time for the main event, babe.” Sunset positions on your lap but facing away from you as she grinds on your flaccid member. In addition to her grinding, you can feel her ass rubbing against you. Sunset continues with pleasing you and begins to feel your member becoming erect touching her pussy lips. “One more thing if you are worried about me getting pregnant, don’t.”

“You’re kidding?” You said.

“Wanna bet? I had some tests taken and believe me or not, you will never get me pregnant since I am a pony. Humans cannot impregnate horses.”

You doubt it but took the risk as Sunset lifts herself a little as she positions your head at her entrance. After giving you a wink with a confident smile, you nod as she begins to take you in. Due to the wetness, your member was easily slid in as you can feel the embrace of her insides as its finally inside. Sunset didn’t make a move yet, savoring the feeling of you being inside her until she starts rubbing her rear on you while looking back with bedroom eyes and gave you a wink. To hell with her teasing, you immediately grabbed both of her wrists and you thrust upwards making her gasp to your sudden action as you begin pumping inside of her.

“Yes, oh fucking yes!” Sunset now closing her eyes while enjoying this. To give her more pleasure you let go of her wrists. You sat up positioning behind her as you grabbed her chests resuming her moans as you now fondle them while thrusting. “Massage them also, it feels so good.”

“You don’t have to speak and let actions do the work.” You let go of them for a while as you insert your hands underneath her shirt now directly touching her breasts. You felt how hard her nipples are beneath your palms as she now moves in sync with your thrusts.

“Oh sweet-Celestia, yeah just like that!” Even though your hands are inside her shirt, Sunset grabs both of your hands fondling her tits as her movement speeds up a little. “I going to cum soon. You Dusk?”

“So close, won’t hold it much longer.”

“Do it, pour it al inside me.” Your movements now cause the bed to creek. You can feel Sunset’s insides quiver on how close she is as you feel your pressure about to spill inside of her. Both of you couldn’t hold it any longer as you immediately remove your hands from inside her shirt as you fell to her bed. “I...I...cumming...Yessssss!” Sunset arched her back while throwing her head up and her eyes closed while spraying all her love nectar.

“Crap!” You screamed in your thoughts as you arch your back pushing upwards releasing your cum inside Sunset.
After twitching for a while Sunset fell on top of your tired body panting as your dick slowly slid out from her pussy with a little of your cum leaking out. Summoning her remaining strength due to the love making Sunset moves off you now lying on her stomach beside you giving you her bedroom eyes.

“That was the best sex I ever had.” Sunset moves hand to your face rubbing your cheek. “Thanks for everything Dusk, you and my friends. I made wrong decisions before, then all of you showed me the light and here we are right now.”

“Well, you did the same thing to me. That shade who almost took over me, thanks for being the light and freed me from the darkness. So, that makes us even.” You grabbed her hand as you kiss the back of it making her blush. “I love you Sunset.”

“I love you too, Dusk.”

After giving you a peck to the lips, you scoot over to her desk and turned off the lamp as you lay down on her bed and called it a night for both of you. Strangely, you felt Sunset scoot over as she positions and rest on top you.

“Sunset?” You asked.

“Babe, I don’t think one ride for me isn’t enough to satisfy me.” Sunset said adding a bit of pressure with pressing her chest onto yours.

“You’re kidding, you are still in heat?”

“Right.” Sunset scoots her face until your foreheads are touching each other. “So, if you don’t mind could you fuck me a little bit more.”

“We can resume this tomorrow, go to sleep for now.” You ignore her request as you close your eyes.

Sunset didn’t give up that easily as she moves her soaked pussy on your dick. You couldn’t focus on sleeping as you opened your eyes to see a determined look on Sunset as your member begins to stiffen with Sunset noticing.

“Now here is how we will do this; we will either resume with our love making until my ‘heat’ goes away then both us can get a good night sleep or I will tie you and gag you up and fuck your brains out until I am fully satisfied.”

“You’re joking on that last part.”

Sunset lifts herself up and moves over to the desk and opens the drawer. She rummaged through it and took out what she’s looking for making your pupils shrink that she is not joking.

“Do I look like I’m joking to you.” Sunset said while holding some sort of gag which is a ball tied with straps. You imagine before she changed and if she did make you her sex toy, you imagine you are in her room but set up as a dungeon like if this is where she lives when she was mean before, being tied up on her bed while the ball gag is in your mouth and blind-folded as she stood over you wearing a black leather bra and thong while holding a whip in her hands. “Yeah, that is how the scenario will be if that happened.” Sunset blurted out after reading your thoughts.

“Like I have another choice. You can’t be that super horny, right?”

“Believe me babe, I am.”

Your curiosity earlier was right about ‘horses in heat’, your girlfriend is super horny right now.

(Spooning position as your girlfriend lolls out her tongue)
“Mmmmmmm, yes, yes babe.”

According to a site you found horses (mares) become in heat during spring and summer months but also can be sexually receptive during late fall.

(Fucking from behind standing while grabbing her wrists, until she climaxes)
“Keep going, I-I...cumming!”

The site said that a mare can be in heat for about approximately six days, some say from four to ten days.

(Hug fuck while she sits on your lap making out with you)
“I want you, I love you so much babe.”

You just hope she isn’t like this every day and/ or when her anestrus stage will kick in or that she can control her body going in heat.

(Releasing her from a mating press and went missionary)
“I am almost there.” Sunset wraps her legs around your waist.

“Same here Sunset, same here.” You groan as you are about to reach your climax.

“I-I love you...I-I...aaaaaahhhhhhhhh!” Both you and Sunset came at the same time.

You are relieved that after she/ you/ both of you came at the same time, she gave you time to rest then resume. Both of you started at around let’s say 9 pm then both of you lasts until midnight. You lay there on her bed tired while she on the other hand snuggling next to you like a bug in a rug while eliciting cute snores.

“Thank goodness.” You thought as you are about to close your eyes and finally get some rest. “Now on how to deal with her going in heat again. Either I ask Twilight Sparkle or ask a favor from the other Twilight.”
