Rainbow Dash moaned as FrostBite thrusted into her depths. Each of his thrusts slamming deep and hard into her, it was like nothing she had ever felt with another stallion.

FrostBite growled softly as he nipped at her neck a few times. As he worked up his pace FrostBite he clamped down on her neck.

Rainbow moaned as she felt him bite down on her. Gasping in surprise she let out a moan as she felt him growl into her. As he bit down into her, Rainbow let out a muffled scream as she arched her neck. Her eyes rolled back as she felt blood drip down her neck. It was like nothing she experienced before. In a single moment her life can end, yet it was the safest she had felt while feeling so alive. Even though she was gagged and pinned under him she felt free.

In a similar instance, FrostBite felt closer to Rainbow than he had before. He had heard about what a true mating was like. But to actually, to choose his mate and claim her as his own was a different story. Their bodies slowly moved into perfect rhythm as time passed.

However, the next step was going to seal their fates. Or at least hers.

Seeing their friends deep into their mating, Ocellus and Sunburst sat and watched happily as they used their magic to pump a dildo into the other. Meanwhile Twilight took notes as she watched in concern while idly used a nearby dildo to mimic their motion.

FrostBite growled softly into Rainbow's shoulder before letting go and licking her neck. His hip thrusting hard and fast showed how close he was from organizing. Licking the blood from his teeth and her. He moved to the other side and lined up his teeth with her neck, carefully taking her neck in his mouth.

Rainbow moaned softly, her body relaxing into his grip as lifted a hoof to the back of his neck. She had been told about times like this where her life would be on the line. However, she felt as if he was letting her know that nothing would harm her… somehow.

Rainbow and FrostBite were moving in unison as they slowly got closer to a shared climax. FrostBite bit down on her neck more till he tasted blood. Pulling back he pressed his tongue into the wound. The heat of his draconic saliva burning into her body, causing her to scream into the gag. Surprising FrostBite with an orgasum.

FrostBite slammed into her and climaxed causing her to have a second orgasum. He slowly pulled out watching her collapse. Seeing her heavy breathing, FrostBite laughed down next to her, putting his head next to hers.

Seeing the blood, the other three moved over and laid next to Rainbow in concern for their friend. "Is she going to be ok?" Twilight asked.

"Only time will tell. Ember explained that when a dragon chooses their mate, the male would mark them by mixing his DNA with hers." FrostBite explained. "Even with dragons, there's a level of risk. Her body can reject the new DNA or she can bleed out." He paused to lick up some of the blood. "If she survives… then it's almost a certainty that she'll be pregnant." A smile crossed his lips as he nuzzled Rainbow. "It's up to her now."

"So… do we all have to go through that?" Sunburst asked.

"No. It's not something that is for everyone. Doing two was the max that Smolder said was the limit I should do." FrostBite explained.

"Why?"

"The risk… and heart ache." FrostBite sighed. "I… I'd be sharing my heart with several partners. When… when one partner dies…"

"You mean…" Twilight gasped. "You'd…"

"Yes… I'd be a she'll of the stallion I am. That's why… It's recommended to have one or two. More partners means more risks."

"But what about us? Your herd?" Ocellus asked.

FrostBite smiled. "Having you three and the others will be a great help if something bad happens. And before you ask. Yes, even the herd members can get pregnant."

Hearing that, Twilight and Ocellus ideally rubbed their stomachs. FrostBite smirked seeing their reactions. "Don't worry. In time, I'll be happy to give you and the others a child if you want." With that, they agreed to rest around Rainbow and FrostBite to show their support for them.

Castle of Friendship
Spike looked over his notes as he heard the front door open. Getting up he walked over with a smile at seeing Shining Armor and Cadence. Upon noticing their expressions he slid to a stop. "What's wrong?" He asked.

"Have you seen Flurry or Twilight?" Shining asked.

"No… and I'm starting to get worried. Twilight hasn't been gone this long without contacting me. And I thought Flurry was with you." Spike replied in confusion and concern.

The two looked at each other before turning to Spike. "Do you know what's happening?"

"With FrostBite? I… may have an idea." He replied motioning to the table before the three looked over the notes.

Outside FrostBite's house
Flash took a deep breath. "I hope I'm not too late. Or making a mistake." Turning he blinked at three ponies that seemed different. "Aren't they?... they look different… somehow. Sweetie? Apple Bloom? Scootaloo?... what's going on?"

In Canterlot
Luna looked around before whispering to one of the guards before locking herself in her room. Taking a deep breath she entered the dream scape, Luna used her magic to send out magic clones to tend to the dreams and take notes for her as she made her way to FrostBite's dream. "Ok… you can do this." She told herself. "Just look for any discord and forget about the…" She froze at the door. "Odd… there's something… different about this dream." With a deep breath she stepped in ready to look into what was going on.

Things are getting spicy. Hope I explained things well enough. What do you all think? Any guesses you'd like to toss out?
