"Dip pens give you a greater amount of line width variation, but you do have to—as the name suggests—dip the nib quite frequently." Weiss demonstrated the full range of flex as she started writing.
Blake watched in fascination as the ink flowed from the nib. As the pressure from the downward strokes splayed open the tines, the ink held up as a continuous, translucent, iridescent film as the nib continued to lay down a broad, blue swath on the paper. Finally, as the ink in the breather hole dwindled, the surface tension broke and the bright white paper was suddenly visible through the gap.
Weiss caught amber eyes staring. Well, that was kind of the point. "Like what you see?" She couldn't keep the smugness out of her voice.
"Why yes."
Uh-oh, that tone of voice can't bode well.
Blake stood directly behind Weiss' chair and leaned forward, stopping just short of making full body contact. She gently trailed a pair of fingers along the dip pen and up Weiss' arm, slowing drawing across her collar bones, ending with a loose embrace around her neck. "The shoulders on the nib are quite something," Blake breathed into ivory locks.
Weiss couldn't see Blake's face, but she'd bet anything that there was a glowing smirk.
Her other hand slid down Weiss' side and stopped at the waist. "But the body isn't lacking either." There was a gentle purr in her voice as her hand slipped lower to rest on a thigh. "Tell me, just how far can these tines... spread?" A gentle nudge accompanied the question, provoking a shiver.
Weiss barely swallowed a whimper as the hand on her leg ghosted its way towards the center of her stomach and down.
"Or maybe I haven't primed the sli—"
Nope, not going there! Weiss sized the wandering hand with a jolt and turned with narrowed eyes. "Are you trying to tease me to death?" she hissed.
Sure enough, Blake had a blinding smirk plastered across her face as she reached out to caress Weiss' brilliantly flushed cheeks. "Capillary action's a hell of a thing."
