It wasn't often that Mac took the more aggressive role in their loveplay, an it still startled Uldren when it happened. The man's words were barely needed, since his normal reaction to losing control was to lash out, and he sank his teeth into Mac's throat even as he continued to thrust into the painful pumping of that gloved hand. The pain and the taste of blood drove him right to the brink, that combination being such a powerful stimulant he only barely managed not to climax right then. Uldren flexed his jaw as his own hand moved on Mac, driving his teeth in deeper even as the wound tried to heal. He growled loudly, the sound almost a purr as he tasted a fresh spurt of blood.

He and his sister had spent years playing bedgames and very little had been considered out of bounds. Both of them enjoyed being dominated at times, though more often than not it had been Uldren in the more submissive role, and the unique mixture of pain and pleasure had become an addiction to the pair. Over time, they'd pushed all the boundaries they could, and the result was what the Guardian currently had to deal with. Uldren was not a lover for the faint of heart, and he usually gave twice as many bites as kisses, even on a good day. At the moment, plagued by worries and jealousy, all kindness Mac might see would be completely accidental.

Uldren thrashed and squirmed, squeezing and pumping Mac's dick in time with the hand on his own. He continued to growl, moan and bite the Guardian, though he didn't break the skin again; one good taste of blood was enough for the time being and slaked his thirst for revenge.

"Come dammit! Finish already! Now Mac!"
