Short: Only Hermione
Only Hermione could tear his attention away from the garden he’d spent the last year reorganizing and remaking. Only Hermione could transfigure two empty flowerpots into trees and conjure up a hammock between them. Only Hermione could be six inches shorter and fifty pounds lighter and still manhandle him into a hammock. Only Hermione had a smile that made Neville’s concerns about his garden fade away in an instant
Only Hermione’s form could feel so good resting on top of his body as she rolled so that her back pressed down on his front. Only Hermione’s bum could press him just enough to drive him mad and not enough for him to take her right there. Only Hermione’s hair could smell sweeter than the flowers, and felt bloody fantastic against his skin. Only Hermione’s hands could gather up his to place them on her stomach with both firmness and gentleness. Only Hermione’s breasts could feel so perfect in his hand, as if they had been made for it. Only Hermione’s gasp of surprise could turn into a moan of pleasure.
Only Hermione could wait a full minute of this, just whimpering and shifting about until she finally turned around. Only Hermione could suddenly shove him out of the hammock and onto the grass and make it feel like a blessing. And only Hermione could leap on top of him and rip his clothes off and take him and make him give voice to his love for her.
