That morning Rainbow Dash was the first one to wake up they were upside down on the bed, but still on there back. She turned her head to the side and saw the sleeping alicorn princess right beside her. She thought about waking her... But Twilight really did look cute when she slept, maybe she could let her sleep in... just for now. She brushed Twilights main to one side and gave her a peck on the cheek, only to be met by a moan by the sleeping mare. To her surprise Rainbow also felt the urge to moan, building in her through her body. Did it suddenly get hot? What was with this tingling? Why was she suddenly aroused? An answer came from Twilight talking in her sleep.

"mmmmm, I'm so sorry nnff I was late to cla-haaaassshhhh Mshh. Celestiaaaaaaa" Twilight mumbled/ moaned to herself.

Rainbow immediately lifted the covers and saw they had both wet the bed. Not with urine, but with arousal. They were soaking wet, a stain of sweet smelling fluid had spilled forth from there legs like a waterfall. Twilight was having one of her sex dreams, and Rainbow was leaching off the pleasure, given the amount had been for some time. Did two heads mean there libido was doubled? She must have orgasmed at least once by now. The smell flowed into Rainbow's nose turning her on slightly. They were so heated steam was actually rising. Dash never considered Twilights unique sent, but now that she was sopping wet, it was all her brain could possess. She shared a vulva with the mare, meaning she was just as aroused as Twilight at the moment, even if she couldn't see the dream. Just feel the pleasure flowing into there shared cooch. And ohh there was so much pleasure to share. Rainbow had masturbated before on her own, many times in fact, that was nothing like what Twilight was capable of in her dreams. Twilight moaned and they both shuddered. The tingling made it hard for Rainbow to focus on what Twilight said next.

"Tha ruuoooooolur will fit. nfffff I prommiss." Twilight drawled out saliva flowing from her mouth.

What was happening in that head of hers? She should wake her up and find out... But at the same time... she was close to finishing. Rather Twilight was, meaning they both were. If she waited till after... then she got a free orgasm. Maybe even one of several last night, if the stains were to be trusted. Still, this was kinda hot. Dash started fanning her crotch with her wing, but this only exited it more making her turned on. The cold flowing air made her feel even hotter. Twilight was starting to pant hard in her sleep. Rainbow clutched the sheet in her fist, biting her lower lip as Twilight moaned again. Almost there. Rainbow's wing flapped faster and faster as they got to the edge of a climax. Just a little longer and they would be at an orgasm. Her wing was moving so fast that it was a blur. The arousal was so intense Rainbow closed her eyes, leaning her head back and taking in as much pleasure as she could. They were both sweating like they had just worked out for hours. But however fast the wind blew across her vulva it wasn't enough to get over the edge they both teetered on. By this point she was tempted to jam her own fingers in and do it herself. But she resisted, partially because she was worried that would wake the purple alicorn, and also partly because she was currently to paralyzed from pleasure even lift a finger, much less stick one in to finish. Just a few more se--

They both screamed out in delight as a geyser of sweet smelling clear liquid flowed out.

The orgasm lasted far longer than any Dash did on her own. Again she wondered if two heads meant double the time of an orgasm as well. It didn't matter, she never wanted it to stop. Her and Twi both shuddered as the discharge flowed out like a geyser onto the already stained sheets. They were both sweating and panting, but only Dash was still conscious. Finally the climax passed and she was left with the smell and stickiness that followed drenched in sweat and discharge. She rode out the after glow tracing her inner thigh with her finger. That had to be the best climax she ever experienced. And it was all thanks to Twi. She had to thank her some how. In that moment the only thing her horny foggy mind could think to do was kiss the book horse on the lip.

With all the passion she could muster the Wonder Bolt locked lips with the princess just as her eyes fluttered open. For one solid minute the two were lip locked staring into each others eyes in confusion both mares blushing as they stared into the others eyes.

Eventually however after a full minute, they parted; a trail of saliva still connecting there lips. Even Rainbow at this point didn't even fully under stand why she kissed Twilight. Maybe it was heat? Maybe she wasn't thinking clearly? Maybe Twilights subconscious lesbian hormones were influencing her? Did it have something to do with it being Twilight’s heart pumping the blood? Was it all really just an in balance of hormones? Or was it something deeper? Did they really share a connection beyond there obviously physical one?

They just stared at each other in utter shock, there muzzles inches apart and saliva drooping before finally breaking, there shared lungs rising and falling heavily.

"Ummmm," Rainbow finally broke the silence. What do you say after that? After sharing pleasure with another mare in bed with you and kissing them on the lips. "Sleep well?" was all Dash could think off.

~~~

After yet more awkward ness, multiple explanations, and frantic apologies on both sides, Twi and Dash both agreed to never EVER reference this event again and set out to take it to there graves. This now comfortably sitting in second place as Twilights most embracing moment, just under the event at Pinkie Pie's slumber party she swore to never speak again, and above her finding out she spoke aloud her sex dreams, followed by going to the bathroom with Dash yesterday. However she may need to reorganize that list yet again in a few minutes considering her and Dash were about to wash off the smell of sex from there fur.

They both avoided eye contact in the shower, letting the water flow down there shared body, taking the sticky substance down the drain. Dash and Twi kept to them selves (as best they could given the circumstance) and washed there half of the body. But it soon became obvious that certain parts needed two hands to clean. Twilight turned to her right to ask Rainbow for help, only to seen the flyer rubbing an absurd amount of suds over her breast with her eyes closed licking her lips.

"Dash!" Twilight shouted, making her panic and cover both breasts, only to remember and put her arm down.

"Yes Spark?" She asked in embracement. Twilight rarely got to see Rainbow's mane wet. Usually it was whipped from wind and a total mess, given how good it looked straight; that was a genuine shame. The way the colors were evenly distributed, water flowed down her muscular shoulders to her grown breasts covered in suds a--

No. No. No. Stop.

Twilight shook her head. She wasn't going to think like that. Rainbow was her friend, and right now they shared a body. She was not going to take advantage of her in this state. It was no excuse to take her hand and brush aside her mane like she was doing right now, leaning in to--

Before she could the pegasus beat her to the punch and kissed the alicorn. There tongs naturally flowing into one another's mouths in as the simulated rain of the chamber drenched them. They rapped there arms around one another, hugging them self, bringing there heads as close as they could come. The egg head and the athlete kept making out getting all there pent up feelings for one another out of there system. They groped, kissed, fondles, and finger banged/ masturbated one another till all they could think about was each other and the pleasure that they shared as one mare. By the end of it both were spent, there body unable to keep up with the other as there shared orgasm, after orgasm had drained both at once.

They ended up having to take a second shower to get all the filth of the first one, this going much faster since they now knew were they each stood. They were both in deep love with each other. Maybe it was temporary, maybe it was a result of the spell, maybe it had always been there from the start just underneath the surface. But regardless, the composite mare's heads were both deeply in love. Even if it was temporary they were happy to have shared the experience and no longer need to hide it.

~~~

After drying off Twilight made her and Dash pancakes with her magic, but there seamed to be less than a normal.

"Hey Twi?" Dash asked as Twilight took a bite, some syrup dripping sexily from her lip. "What's with the small portion sizes?"

Twilight politely chewed and swallowed before responding. "We need to be carful what we eat. We have the same stomach remember?" Twilight patted her shredded abs curtesy of Dash's traits. "Also I don't know precisely were our throats connect, so we should be carful eating for a while, so we don't make the other choke." That was her Twilight, always thinking everything out logically, that was one of the things that made her so cute in Dash’s eyes.

Satisfied with the answer Dash consumed Twilights pancakes without a second thought. Twilight was right. Even though she only ate half her normal breakfast she felt full, what was even better was with Twilight eating half at the same time as her, they finished in a fourth the time it would take on there own. And a faster anything was always good in Dash’s mind. It also helped that Twilights magic could cook really good food. Dash didn't think she could cook her own breakfast for her self again now that she had tried Twilights magic pan cakes. Once finished Dash let out a loud burp much to Twilight’s annoyance.

“Sorry.” Dash apologized. Twilight sighed.

“It’s fine. Just something I have to get use to for now.” Twilight Sparkle said looking out the window hand resting on her chin.

Twilight was of course right, even if it was temporary they still had to get use to the idea of being on the same shoulders.

“You know Rainbow?” Twilight said. “How about we do what you want today.”

Dash’s eyes widened. “Are you sure?” The pegasus asked hopeful. The alicorn head nodded.

“Yesterday you were forced to spend the majority of the day sitting in a chair with me looking for a solution.” Twilight crossed her leg over Rainbows. “It’s only fair you get a turn.”

Before Dash could answer there was a knock at the front door. They both mentally panicked, neither had had any chance to tell there friends what happened to them. And both were worried how they would react. They both made there way to the castle door in a hurry, they still fell a few times. But they made better time than yesterday.

~~~

Twilight opened the door only letting her head and shoulders be visible. She was met by the wall eyed innocent expression of the mail mare Ditzy (Derpy Hooves) Doo. The Pegasus blinked a few times before finally focusing on Twilight as best she could.

“I have a letter for ms. “Rainbow ‘Crash’.” She said producing said letter from her bag. “She in there with you?”

Twilight started sweating, but nodded. “I’ll get her right away.” She said nervously slamming the door closed. Half a second later Dash appeared on the other side of the door looking just as nervous as Twilight.

Derpy rubbed her eyes wondering how Dash could get there so quickly? but merely shrugged figuring she was the fastest mare in equestria and not thinking too hard about it. She handed her the letter then flew off to deliver more mail.

~~~

Inside Dash opened the letter with Twilights help and started reading. Her face turned white as she read every single line carefully. She turned to Twilight and finally said.

“Twilight, we need that separation spell soon.” Dash held up the letter carrying the official Wonder Bolts wax seal, now broken open. Twilight read the letter to. It was only 17 words long. But it made her blood run cold:

”Dear Dash,

Report to Wonder Bolts training in two days. Or you are discharged.

Signed,
Captain Spitfire"
