...we can take it nice and slow...

"Rarity, this is not some kind of erotic dream, I have lived my whole life in libraries and have read enough books on sex ed and physiognomy that I know not to just slam my shaft into a Mare without getting her properly lubed up and opened first." Spike says in a deep throaty purr, but comes over and flicks out his long serpentine tongue against the slowly increasing wetness of Rarity's cunny, wrapping the forked tip around her clit under it's hood and jerking on it like it were a phallus. Rarity hisses through her teeth and then whimpers in arousal as Spike touches that very sensitive area, but Spike, unused to the sounds and acts of sex, just having read about them in very technical language, thinks he is hurting his lover and pulls back.

"I'm so sorry Rarity, I didn't-" Spike apologizes before Rarity interrupts.

"Spiiike!!! Why did you stop? I was just starting to enjoy myself..." Rarity complains.

"But, I thought I was hurting you?" Spike asks in confusion.

Rarity instantly realizes what he means: and what THAT means, and is shocked all over again. "Spike, I am your very first time, aren't I?" She asks with a blush.

"I wouldn't want anyone else!" He declares with passion.

"Well then, we will have to borrow a little bit from the BDSM scene for this. My 'safe word' is 'Geode', unless I say that word, just by itself, even if it sounds, looks, or feels like you are hurting me I am actually enjoying it. Now, as your first partner it is my job to give you your safe word, but since it needs to be one you can remember and say under the most trying of circumstances I am going to ask you to pick 5 words I can chose from, just as my trainer did for me. They must be words that would NEVER come up casually during sex, something that would totally stand out in such a situation as not belonging there, so that when you utter the one I chose for you your partner will automatically pause just at the strangeness of it, giving them time to remember that it is your safe word and they have to stop now: understood?" Rarity commands while absently playing with her clit with one hoof.

"Okay, let me think..." Spike mutters as he gently strokes his penis with one hand, highly aroused. "Chariot, Boutique, Library, Twilight, or Volcano." He says after a minute.

Rarity considers quickly, it's a big decision and one that should not be made lightly but she wants to have spike start licking her again SO badly: still, she makes a good and rational choice even under such trying conditions and tells Spike what her answer is. "'Chariot' will be your safe word from now on, 'Boutique' and 'Library' could easily come up in foreplay since that's where we live, 'Twilight' is your adoptive mother and my best friend's name and would turn me off, and 'Volcano' could come up when you were about to orgasm, so 'Chariot' is my choice for you."

"Okay then, now, are you ready?" Spike asks nuzzling Rarity's neck with his scaled snout.

"Gods above yes! Lick me, suck me, fuck me: just give me the orgasm I have been longing for all night!" Rarity whispers in Spike's ear.
