Be mine is on a few levels. He has Lucifer's mind, he has his heart, but now he wants his body. Istredd has been greedy from the start, he wants to consume Lucifer until every part of him is possessed. He won't be satisfied until the physical is too. He wants Lucifer's mindless pleasure, he wants him unable to think of anything but Istredd.

The grip on his hair is more of a clinging and as long as the hand on his wrist isn't restricting, he allows it. Mine, he growls, soaking in Lucifer's lust, encouraging him to push, to jerk and lose composure entirely searching for that bliss. It may not be wise but he only grips him tighter, stimulates him with less mercy than ever. His mouth and hand don't stop, they are relentless until it seems clear he will get his prize.

He envelopes him entirely when he knows it's about to be done, cheeks hollowed out, holding him tight. He is completely enraptured by what they're doing that in that first second, he doesn't realize what is happening. Istredd's instinct, despite what they're doing, being in the throes of passion, is to immediately shield them as he hears everything shatter around them. Neither of them want glass shards on them. Even while taking him in, swallowing in satisfaction, he protects.

Istredd waits for Lucifer but as soon as he seems capable of thought, he pulls away and glances around. Everything breakable is shattered beyond repair. Tiny pieces. He should be looking at horror but he is still turned on and frankly, this only makes him laugh. Laughs mindlessly, mixed in the chaos, his heart pounding and licking his lips.

"That's a first." Smug, smug, smug.
