Each time, she has to battle the more predatory side in her, demanding to be nourished to the brim. It's hard sometimes, especially when she's starving, but not impossible -- that willpower and control is what separates her and her kind from the vampires prowling the woods at night, here.
Pulling away to draw in a deep breath, Pepper strokes her fingers across Tony's cheek before cupping the opposite side of his neck, licking away the trails of blood trickling sluggishly down his skin from the bites, almost purring with satisfaction. She wedges her thigh carefully between his legs, rubbing deliberately against his hard arousal as she latches back on for the final few pulls, wanting to give him pleasure in exchange. With a soft moan, she swallows her last, proper taste and moves into the aftercare stage of sorts, alternating tiny sucks and licks to staunch the bleeding.
