Pride goeth before fall.

Anna's nostrils flare and her eyes fill with defiance again. Slowly descending to her knees, her eyes shift from yours to your cock. After another deep breath and loud swallow, she takes it into her mouth.

Again, small bursts of adrenaline run through your system instead of sexual pleasure. Looking down, you see Anna fighting to keep herself composed, fighting the urge to gobble you down to the root, and to power through the micro-orgasms racking her body. And for once, Selas' spell works to your advantage. "It really must have been the cardio," you yawn dramatically, not bothering to cover your mouth. "I mean, it has to be. I'm not feeling anything. Maybe I should come back some other time, when you could actually put some effort into this."

Selas oohs invisibly, kneeling beside Anna, silently negging her on and asking if she's going to take that. But you don't think that the extra encouragement was necessary. Anna flashes you an annoyed look before inhaling through her nose. Placing her hands on your hips, she inches closer to you, stuffing more of your cock into her mouth until she has to stop for a breath. With a loud gasp, she spits on your cock like she's spitting venom before going back to sucking it.

The tremors of adrenaline become more subdued and muted, with an occasional spike. Anna tries to play it off as her gag reflex kicking in, but you just look at her, with a bored look on your face. Apart from that yawn, you have made absolutely no noise. She frowns and doubles her efforts, determined to prove you wrong and get you to react.

What she does get you to do, is raise your eyebrow at her in a modicum of respect. You feel literally nothing from her, meaning that she's managed to suppress her own desires, to focus on yours. But her efforts have not gone to waste. From all those little orgasms she's been having, Anna's managed to get your stock to about just under what Mei gave you, and you sense that when Anna goes off, you should have enough to survive your next encounter with a demoness.
