If Lazarus hadn't been wearing the amethyst ring, protecting him from mental fingers - both from allies or hostile foes - he would've thought Jake was a mind-reader. The scene in front of him was enough to bring his rod back to life - divining sex in the same way that the magic ones divined water. As Jake forced himself deeply into the mortal's throat, Lazarus grinned and reached down to remove his boots, using the bedpost to keep him upright so he didn't miss a moment. Jake seemed to think of humans and treat them exactly as Lazarus did; selfishly. He and Jake were Gods, smiting whoever didn't worship them, pleasuring themselves with whoever did. They took what they wanted and demanded the rest, and nobody dared to leave them wanting. Oh yes, he and Jake might've had a rocky start, but things were looking up. Just like his cock, springing forth from his unzippered jeans. His shirt was the last to go, and when Jake finally looked Lazarus' way, he would find the ancient vampire naked and ready.
Wanting a smooth and unhindered entry, he found lube - easily accessible from the bedside drawers. He'd intended on pouring it onto his fingers but the stuff went everywhere, practically covering his whole hand. Well, he could use that to advantage, too. He tossed it, too busy looking at Jake shaking his ass - well, thrusting it back and forth at him, anyway.
Lazarus crawled onto the bed, working his lubed hand upon himself before reaching out for Jake. At first he used his thumb, teasing and circling only when Jake pulled out of the mortal to meet him. If he wanted more of Lazarus' fingers, he would have to pull all the way out of the mortal to get them - something Lazarus didn't think he would do. Eventually, impatient to be a part of this playtime now, he thrust fingers in all the way, wriggling them inside and pushing in time to Jake's movements. Not long after, his fingers were removed and he aimed himself with a lack of care that had him shoving roughly in just as Jake pulled back.
Oh, but there was no resistance beyond the usual tightness for Lazarus had worked Jake's body nicely. He closed his eyes and focussed only on the sensation of sliding in and out, and by extension, fucking the mortal beneath Jake as well, for it was Lazarus' rhythm that was now the master of them both.
