Stefan smiled, fond and amused at the warring impulses in the girl, the urge to please and to indulge, selfishly, still unused to pleasure. She'd learn control in time, but for now he enjoyed watching her struggle. He slid his thumb across the chain clenched in her teeth and then moved it down to cup her breast, lifting the soft flesh to give her nipple relief before letting gravity lower it again. He did the same to its twin, watching her reactions.
Something more mature, yes. That lifted her breasts, emphasized her small waist, but provided easy access for whatever hole he wished to use. But something feminine, too. Lace and silk rather than leather or latex.
The fantasy blurred with the reality in front of him, and he was not unaffected by the power of the image, of wanting to see Elena writhe for him, pleasuring herself without need of his aid. He wanted her confident and sensual now.
