Generated using the PurpleSmart.ai pony-specific Stable Diffusion model.
The prompt used to generate it was:

`lyra heartstrings with a sultry look, pony, face down, ass up, tight panties, unicorn, white hair, short skirt, teal, quadruped, suggestive, sexy, solo, highly detailed, digital painting, artstation, concept art, smooth, sharp focus, illustration, 8k`

This was also slightly cleaned up by hand, as the AI insisted on giving her an extra leg.
