30- Teeth:

Black Hat knows about his charm. He 's proud of it. He likes the mortals' attention, so easy to tempt, a smile, a glance, a graceful gesture, a sutil hip movement and they are at his feet like worshipers to a god.  

Flug, always insecure, is deeply jealous. Is not that he doesn't trust him, more like he doesn't trust others. There's always someone who dares to touch him without permission, professing their desire and adoration like it is nothing, meanwhile Black Hat smiles with vanity and delight. 

But Flug has his ways to mark what belongs to him, to make Black Hat remember to whom he belongs to. 

You see, the deceptively sweet Dr Flug is not human, under that bag he hides a mouth full of fangs and those fangs are one of the few things that can break through the skin of that invulnerable being. 

The days that Black Hat chose to be specially flirty with his clients, Flug waits, patiently. He knows that his Jefecito does it on purpose, he likes to provoke jealousy on him. Flug doesn´t mind to please him.

Finally, when they are alone, the doctor approaches decisively and captures him on his arms, squeezing the slim figure with all the strength that he is capable of. Black Hat permits it, always smiling, holding on to his shoulders, eager and expectant, knowing what awaits him. 

The long black coat ends on the floor and the red silk shirt opens just enough to show his neck, Flug can feel it, the delicate veins under the skin, the heart of that creature beating a little bit faster. 

Flug takes off his bag, a cumbersome object for that kind of thing, gets close to his neck, speaking in a whisper.

“Who do you belong to? Jefecito” he asks, barely touching the skin with his lips.

“Oh~ I wonder the same. Why don´t you remind me?” He answers, provocative, tempting.

And Flug sinks his teeth, penetrates the skin, drinks the blood and leaves a mark that is going to last for days. 

Black Hat trembles in that delicious mixture of pain and pleasure, moans and clenches his teeth, drooling with delight . Claws at his shoulders, leaving his own mark.

“Whose are you?” he asked again, barely moving away to speak.

“Yours~”.

“You like me to remind you of it. Don´t you?”

“Certainly” Black Hat smiles “You should do it more often”
