Aries tilted his head hearing that it was just a birthmark, but nodded all the same. It was distinctive, if nothing else. And as it was his mind was soon taken with their current position, and when given permission he began gently washing Luca's nethers, careful to get him clean but not be too rough. He smiled softly as Luca threaded his fingers in his hair, content with what he thought was an innocent action, and soon he finished washing him up.<br/><br/>He hadn't thought his question would excite the other all that much, he was merely curious if it was something that would make Luca happy and feel good, though the lag in a reply made him feel as though he had asked something he shouldn't have. He watched the other with a slight bit of worry, maybe he'd said something bad, or at least weird, and he was about to apologize when he heard the man's low voice. He felt his heart skip a beat and feeling the soft tug to his hair sent a soft shiver of anticipation down his spine… he liked Luca's tone, the look he was giving him.<br/><br/>His cheeks darkened when Luca told him he could right now, not having expected him to want to go again so soon, but already Aries could feel his own body warming up to the idea. "Ah, Luca doesn't have to…" He said, flustered as even thinking about switching roles sounded so good, but also he didn't want Luca to do something just to return the favor. But, kneeling there while Luca smiled down to him, the fingers in his hair and feeling more like the prey under Luca's stare, he could feel his heart beginning to beat loudly all over again.<br/><br/>"Mm, I want to make you feel good this time… since you just made me feel good." He said softly, pouting a little as he turned his eyes to the other's manhood. He moved a hand from the man's thigh to gently grip the base and leaned forward where he licked softly at the tip, along the slit, and then moved down to lick from the base back up again… it was somewhat random, he wasn't sure how he should lick him, where, or if it even felt that good. He flicked his grey eyes up to watch the human's expressions as he focused his tongue more on the underside of the head and gave a few careful strokes with his hand. He wished he was as good as Luca was, that he knew more about what he was doing, but he was thankful that his partner was patient with him while he learned. He was also glad that Luca had assured him that getting hard while doing these things was okay, as already his own need was growing again and he soon dropped his other hand down to give himself soft strokes to ease the ache of wanting he felt. He wasn't sure why licking Luca made him feel this way… but he decided it felt good licking his partner. He was glad that Luca let him try it, and the vampire was soon looking up to the human with wanting eyes despite not realizing as much himself.
