Escalate.

Why do you even bother talking? You know she only responds to one thing. "Selas, can I ask you something?"

She lets out a short annoyed sigh and snaps her book shut. Turning her head, she manages to say "Wha- MMPH!!" when you suddenly cram your cock into her mouth.

You brace yourself for excruciating pain, but as you've hoped, Selas immediately starts sucking and sliding her mouth along your shaft, moaning sweetly. You had calculated that there was a 10:90 chance that she was going to bite your cock off, but you breathe out a sigh of relief that she didn't.

Enraptured by your cock in her mouth, she shifts onto her seat and leans against the arm of it, so that she can get a better angle to take you in deeper. Tilting her head, she brushes away some hair to look at you. You can see her consider saying something, but because that would require taking her precious cock out of her mouth, she prefers to encircle it in as many tongue loops as she can, and squeezes it tightly as she bobs her head.

Groaning, you put your hand on her head and add a little bit of magical energy to your cock. Not enough to be obvious, but maybe just to add a little tingle for her. A gleeful exhale comes out of Selas' nose and her eyes flutter as they roll up into her head. Her tail wags happily and freely behind her, and it gives you an idea. Hooking your finger, you beckon it over to you.

Acting coyly, it looks around the room, before motioning to itself, as if to say "Who? Me?"

The corner of your lip rises as you scoff in amusement and nod. It straightens up in excitement and jabs towards you, wrapping up your torso, to come up to your face, leaving your lower half to it's owner. It's tip nuzzles into you affectionately, like some weird pet snake.

Teasing and tickling it's underside, you pepper it in kisses and licks, and experiencing it's reactions in two ways. The tail itself shivering in delight, and Selas losing focus momentarily as she groans. Slathering it in saliva, you slowly begin to insert her tail into your own mouth, before sealing your lips around it and applying suction.

"FUCK!" Her squeal is mighty and strong enough to tear her mouth away from your crotch. Grunting and hissing at you, she runs her lips down your shaft before finding your sack. Tumbling it with her tongue and playing with your cockhead with her fingers, she spits angrily at you, as you continue to suck her tail. "Of all the creatures... in all the planes... you are, the absolute fucking worst!" Giving your cock another couple of deep bobs, she smears it across her face and glares at you. "Stop teasing me. I command you. As my consort, I demand you to stop your teasing and fuck me."
