Sweetie Belles Lesson

Rarity grinned and lowered the top of her eyelids in one of her very practiced seductive glares...

"Now Sweetie Belle, listen to me carefully. What we are about to do would benefit the both of us very well if it were to remain secret. Otherwise someponies will get the wrong impression of us... Do you understand?" Before Sweeties young filly mind could process Rarity's words, the magnificent mares eyes blinked and fluttered upward in a cutsie innocent fashion breaking her sexual over tone. "Now I can't force you to do anything darling, I'm just saying, this is may not be something to boast about..." Rarity's eyes floated back to her sisters, as if asking for any comprehension. "What are we about to do Rarity?" Sweetie Belles lips could not stop quivering. The little she knew about sex, included that it was necessary for a foal to be conceived, but not much more. So why would Rarity be fronting her utmost sexual side as if to commit such an act? To Sweetie Belle, none of this should be happening. Did Rarity want a baby? Then why her? Why her sister? The reasoning continued to cloud Sweeties mind, 'Could two mares make a baby?' she would not stop pondering the thought. Fortunately, the awkward thinking was interrupted, but by one of the most unimaginable actions in Sweeties life. While juggling her thoughts and emotions about the mysterious fling that was Sex, Rarity had once again dropped her eyes and stepped to Sweetie. Only she had not noticed until Rarity's lips interlocked and partially encompassed hers. Sweeties eyes widened drastically and her pupils shrank to dark specks as she felt Rarity's tongue swish and suckle, picking up all of her saliva and tasting the delicious sweetness. Sweetie Belle pulled away from her sister, leaving Rarity barren without any comfort or pleasure to reside in the fillies mouth. "R-Rarity?! H-How could you-? What were you-?" Sweetie tried and find the words to interrogate her sisters behavior. The elegant mare cocked her head in a bit of shock and defense, though it was quickly shaken as she smirked to the strand of mixed juicy spit the two had produced in each others mouth, dangled from her sisters bottom lip. Sweetie Belle stood and her eye began to twitch in disbelief of how coy and humorous Rarity was being. "Oh please deary... that was just a little warm up peck, you should always get a taste of your partner, just to see if its right... Hopefully the taste was familiar to you as it was to me...." Rarity grinned and slowly walked to Sweetie, getting cocky as she somehow found victory in acknowledging incest hoping to comfort her sister... In her own special, lespony way.... When reaching her sister, she placed the side of her muzzle ever so slightly to her cheek, Sweetie didn't object, but was very weirded out. Panic arose in the filly, but was also fought with something else... Passion, lust, and of course, Rarity's body. The power of her comforting snuggle on her sisters cheek was enough to force the curiosities out of Sweetie Belle. Rarity quickly puckered her lips and shifted her mouth further to Sweeties cheek, then she felt the fur rest into her mouth as she sucked, making a slight smacking noise, then in a heartbeat ending the kiss only to go back to the snuggle smearing her spit onto her cheek while rubbing it with Sweeties. Sweetie let out a long lusting groan for Rarity, wanting more love and forgetting all notions of right and wrong, good and bad, and inbreeding... "Awwww...mmmnnuuhhmm..." Sweetie Belle fidgets in Rarity's embrace. The striking mare pulls away from her small sisters frame, "Sweetie Belle..." the filly looks up "Rarity?" The two ponies eyes catch each other and a spark shoots between them. There had been few ponies Rarity truly felt for, let alone slept with. But now she understood, her sister would provide the perfect chemistry, who else could truly give love then her flesh and blood. A similar feeling over-brushed Sweetie as well, the two then interlocked hoof-and-shoulder to Rarity's bed...
