Natsu's muscles slacken as he feels Lucy's influence spread through his body. She coils her serpentine lower half around him, the smooth scales sliding against his skin. He inhales deeply, her intoxicating scent filling his lungs.
"It feels so good to give in, doesn't it?" Lucy whispers, her breath tickling his ear. "To let someone else take control for a while."
Natsu's mind goes hazy with a pleasant, dreamy sensation. He nods weakly in agreement, a dopey smile spreading across his face. The redhead feels weightless, untethered, as if floating in a warm bath.
Lucy begins to sway gently, undulating her coils in a sensual rhythm. Natsu's body instinctively mirrors her movements, the two moving as one. "You look so handsome like this," she murmurs, running her fingers through his hair. "So desirable. I could keep you wrapped up like this forever..."
Natsu lets out a soft groan of pleasure at the thought, a shiver of delight racing through him. He wants nothing more than to please Lucy, to be her willing plaything.
The lamia smiles, pleased with how thoroughly she's ensnared the young fire wizard. Lucy tightens her coils just a bit, applying a touch of pressure. "I think I'll keep you, Natsu. My adorable little pet, to tease and tantalize as I wish. What do you think?"
"Y-Yes," Natsu manages to stammer out, too lost in bliss to refuse. "I'm yours, Lucy. Do whatever you want with me..."
Lucy chuckles darkly, thoroughly entranced by the sight of strong Natsu so pliant and submissive. "Mmm, good boy. We're going to have so much fun, you and I..."
