You are Spike the dog and you were walking the fields of Canterlot High when you spotted Rarity.
Rarity: Hi Spikey Wikey. "She smiled happily"
Spike: Woof. "He barked"
Spike then climbed and sat on her lap and placed his paws on her breasts
Rarity: Oh my dear, you're such a baby today. "She smiles and blushes lightly as his paws are on her breasts"
Rarity: You look a little lonely. Have you been properly played with? "She blushed a little as she scratched his back while he rested his head in between her breasts, still had his paws on them, practically hugging her breasts, leaving him to his imagination as he was blushing and had hearts in his eyes as he fell in love with her breasts"
Spike couldn't help but feel content in her embrace as he was in a state of bliss. The soft scent of her perfume, the gentle rise and fall of her chest as she breathes, the feeling of her slender fingers scratching his back. He nuzzled even harder into her breasts, as his tail happily wagged. Spike can't help it as he had his paws on her breasts, resting his head in between her cleavage breasts, hugging her breasts, and they felt so soft and warm, they smelled so sweet scent of her perfume. The gentle rise and fall of her chest as she breathes. He was in complete bliss, lost in the sensations of her breasts against his face, the scent of her perfume, the feeling of her heartbeat, the softness of her skin. He was basically in love with her breasts and completely in heaven.
Rarity was both amused and flustered by Spike's behavior as she slightly blushed. She couldn't help but feel a tad bit embarrassed at the way his head was nuzzling into her breasts and his paws were pressing on her breasts, but at the same time, she found it adorable. The feeling of his soft fur against her skin, the slight weight of his head on her chest, and the way he was hugging her breasts made her heart flutter.
Rarity: Oh, Spike, you're being such a baby. "She blushed slightly in embarrassment"
Spike: Bark. "Spike can't help himself as he was enjoying it immensely as he was in love with her breasts"
