Ariel was perfectly aware of how much Amadeus would let him get away with - uncomfortably close to doing real damage that would require magic to get Ariel to back off. They had already faced that demon multiple times and likely would again. "I know what your cold, dead heart is capable of," he noted with a sharp grin, "I've already seen the beauty and the cruelty and much in between."
His hands slid down his lover's chest until his claws caught the fabric and it began to shred - just as much as it began to cut Amadeus's skin underneath. This was not light but it wasn't an attempt to shred him either. When he finally pulled apart the shreds of cloth, he leaned down to lick a line up one of the many cuts. His hands settled on his lover's stomach and one claw started to slowly sink in, "Do you ever think about what I could do to you with these?" That claw was getting awfully deep, even with how slowly he was puncturing flesh.
