Give me those foalcoins, Nova

Sweetie eagerly listened to the noises coming from the room next door to hers. The loud sounds of feminine moaning, the steady pounding of the headboard against the wall, the masculine grunts of an unknown pony. She rolled her eyes and sighed in frustration. Rarity must have found another stallion for the night. Was it one of her Boutique's customers, or maybe a regular like Thunderlane or Fancy Pants? Well, Sweetie was sure she'd find out tomorrow morning at breakfast. For now, she had other matters to attend to. Moving her hoof lower down her body, Sweetie continued to listen to the sounds next door as she grazed her lower lips. She let out a moan as she teased herself, not worried about being heard over the rutting that was happening in her sister's room. She pushed her hoof deeper inside herself, the wet arousal of her sex allowing easy access to her own depths. Her breathing increased rapidly, in sync to the mystery stallion's thrusts, as she rode her hoof in desperate need for relief. Her other hoof moved to her clit, rubbing gentle teasing circles around the nub that grew in speed and force as her climax neared. Rarity's voice was growing louder through the wall, and Sweetie raced to finish alongside her sister. With a final thrust of her hoof into her cunt, she cried out in ecstasy as her orgasm wracked through her, squirting her juices out onto her bed. She brought the soaked appendage up to her mouth and licked her juices off as she listened to the sounds of Rarity's own peak cut through the night. As she drifted off to sleep, blissfully uncaring about her dampened sheets, she wondered if perhaps Rarity would let her join in one of these nights. Well, maybe she'd have to wait until she got a cutie mark for that kind of fun, Sweetie smiled as dreams of her and Rarity waited in her slumber.
