He slashed straight downward and cleaved through something, but at first wasn't sure what. Her pained wail immediately thereafter assured that the strike was perfect. She clasped a large bloody gash between her legs, and not just because it was that time of the month, but because Vern had a succubus' natural weak point. Because of their sexual nature, succubi and incubi have particularly sensitive genitalia, offering them much pleasure, but when attacked also much pain.
Vernon wasted no time in grabbing the stunned demoness by the leg and slamming her down onto the ground, causing her curvy body to ripple in slight jiggling waves, which Vern found amusing. Alas, knowing that her claws could still prove dangerous to him even still, He made sure to not toy around with her too much. He pierced the sword between her large breasts, and nonetheless still made sure to miss her heart in the stab so she wouldn't die instantly, instead choking up blood for a short while, all the while Vern gave a few good stomps and grinds of his heel onto the winged demon's nice body, a few boots to the stomach and some punishment to her already wounded womanhood.
She surprised Vernon with how long she lasted with his sword planted firmly in her chest. She suffered for a least two minutes before finally seeming to succumb.
"I like you a lot better like this," Vern chuckled to the either dead or dying girl. He removed the sword and lowered himself on top of her. He got a bit bloody from the leaking wounds, but didn't care. Unable to resist himself from her lovely anguished face, he kissed her right on her plump lips. "Now you were pretty tough, so I better make sure you're really dead, huh sweetie?" he added. He felt no breath or any obvious heartbeat, but when feeling for a pulse he felt like he could feel a slight something. He had no way of knowing, and assumed she was almost certainly a goner, but his slight suspicion was enough for him to add on a little coup de grâce to top it off. With a swift motion, he snapped her neck. The crackling of vertebrae was enough to ensure that she really had joined her friends in death. He gave her corpse another quick smooch for good luck.
"Imp, join me! We're heading through," Vern called. She quickly dashed to his side from the prior doorway.
Continuing through, he noticed right through the the hot spring shortcut was the cave entrance, guarded only by two demon girls armed with spears on either side of the gate. One was a pale-skinned blonde bombshell, whom one might not even notice as at all supernatural if not for her demonic wings. The other was a dissatisfied looking raven-haired guard who wasn't winged, but had thin sleek horns, nearly like little daggers, and a thin pointed tail swaying behind her. She was tall and thin, fairly flat chested, but widened out at her hips, supporting a very nice set of legs.
These two were the only ones standing between Vern and freedom. He planned his next move...
