Lucci snarled as Kaku's tongue inched up the dip between his collar bones.
"What's wrong, pussy cat?"
Kaku grinned, pulling back his lips – Lucci reined in the urge to bash in those neat white rows of teeth, and opted for slamming a heavy paw into the younger male's shoulder.
Kaku stumbled back, teetering oddly, and Lucci delved in the satisfaction of extending his claws, curling them skin-deep into Kaku's sides.
"Asshole."
Lucci sneered at the mumbled insult, a low growl swelling in his throat as he shoved forward. Both were in the middle of transforming into their Zoan forms, and Lucci waved his tail lazily from side to side.
"It's cute when you do that." Kaku reached up, fingers rubbing at a spot behind Lucci's ears. The latter flattened his ears flat against his skull, shook Kaku's hand free.
Kaku curled his inhumanly-long-giraffe-like tongue around one of Lucci's fingers as he eased back into his human shape, pressing his lips around the single digit.+
Lucci struggled against the whim that screamed for him to rip this infuriating tongue out of the herbivore, grabbed a fistful of hair instead, and nuzzled against his neck.+
Kaku stiffened entirely.
Lucci pressed a thumb against the side his neck, sliding it slowly up to the base of his chin, adding his teeth to the mix, scraping lightly against skin.
Kaku whimpered, and tried to adopt an aloof expression when he realised that he had actually did that out loud.
Lucci buried a smirk by busying himself at applying pressure to a few nerve endings that made Kaku grunt and made a sound that was a blend of a moan and a muffled scream.
There is a glint of light glancing off the surface of a pair of glasses, and a slender finger brushes against the bridge of a nose. A voice smiles quietly from the crack in the doorway. "That's sexual harassment."
From Wiki:
+ Due to a subconscious response to suckle milk from their mother, something which many human-reared giraffes and other captive animals do not experience, giraffes resort instead to excessive tongue use on inanimate objects
+ A function of necking is affectionate and sexual, in which two males will caress and court each other, leading up to mounting and climax.
