The idea of that made him react in ways he was unprepared for, but he was excited, too. He'd thought of asking Ariel to teach him but had never gotten the chance. Probably for the best, though, if he thought about it.
Of course, the older man leaning down to obviously kiss him did something much worse, but he had already spoken and Joseph was leaning back, out of reach again. A deeper part of him wanted to grab him by the front of his shirt and pull him back down but he could have exploded at the thought. Where had that come from?
"Well... um. We can't bite. Anymore." If they did and he figured out that the blood bond was doing literally nothing to either of them? You couldn't bond a Tremere anymore and no one could find that out. Then again... Ariel knew.. But that was different. Rhys had to believe that Ariel was a special case and he really, really couldn't tell Joseph. "Or as often?" Added because he could tell it would already be a thing. If he started with those kisses to his neck, he would probably most definitely ask for one at that point.
