The next morning's training session only fed the fire. They sparred in the forest clearing under a canopy of leaves, Juvia's water whips cracking against Lucy's celestial shields. Real Lucy moved with effortless grace, correcting Juvia's form with light touches—fingers on her waist, palm guiding her elbow. "Lower your center," she said, breath warm against Juvia's ear. "You're stronger than you realize. Trust it."
Juvia's cheeks burned. In her mind, the scene shifted instantly. The forest vanished; they were back in the training hall. The same touch became a firm grip, Lucy spinning her around and pressing her chest-first against a wooden post. The cheongsam's slits parted completely as Fantasy-Lucy hiked the fabric up, exposing Juvia's bare ass and dripping pussy. "You tremble so beautifully when I touch you," the imagined voice growled. "This body is mine to train now. Not just your magic—every inch of you."
Juvia imagined the thick head of Lucy's cock teasing her entrance, sliding along her slick folds without entering, drawing out desperate whimpers. "Beg for it," Fantasy-Lucy commanded. "Tell me exactly who you need." Juvia's fantasy-self broke instantly, voice hoarse: "Lucy-sama… please… Juvia needs your cock. Needs to be stretched and filled and claimed until she can't remember anything but you. Please fuck your submissive little water slut. Make her cum only when you say."
The real Juvia nearly stumbled in the spar. She caught herself, magic flaring brighter as she channeled the aching need into a perfect counter-attack—a shimmering water-starlight barrier that Lucy praised with a genuine smile. "That was flawless, Juvia. You're improving so fast." The words sent another ripple through her core. Praise. It was always the praise that undid her in the fantasies—the way Lucy would whisper "Such a good girl" while pounding deep, cock buried to the hilt, balls slapping wetly against her clit as Juvia came untouched, walls fluttering helplessly around her mistress.
Later, during cool-down stretches by the spring, Juvia's mind wandered again. This time the fantasy was slower, more intimate. Lucy lounged on the grass, robe discarded, thick futanari length resting heavy against her stomach. Juvia crawled to her in the crimson dress, heels clicking, slits fluttering with every movement. She straddled Lucy's lap without being told, sinking down inch by inch until she was fully seated, stuffed full and whimpering. Lucy's hands gripped her hips, guiding the slow roll of her body. "Ride me like you were made for it," Fantasy-Lucy murmured. "Look at you—strong enough to fight beside me, submissive enough to fall apart on my cock. You need this, don't you? Need me to own every drop of pleasure you feel."
Juvia's internal voice answered without shame now: Yes. I need to be broken and remade every night. I need to wear your marks under my clothes, feel your cum leaking from me during guild meetings, know that I belong to the one who makes me stronger and weaker all at once. Her pussy throbbed in reality, hidden beneath training shorts, as the fantasy Lucy thrust up hard, flooding her with hot, thick ropes while praising her endlessly. "Mine. My perfect Juvia. Cum for your mistress."
She didn't touch herself. Not yet. The slow burn demanded patience. These fantasies were fuel—secret fuel that sharpened her magic and straightened her spine whenever the guild watched them.
