"So, you are completely aware when you're in wolf-mode, right?"
Lucas' voice came out a little shakier than he intended, but it wasn't out of fear. It was out of anticipation for what he was about to ask his boyfriend to do for the first time in their two-year-long relationship.
Jace huffed in laughter. "Yeah. I've told you before: It's all me. With a weird urge to just haul ass in no particular direction through the woods all night."
They were hanging out on his bed, cuddling and just quietly enjoying each other's company while a playlist of indie rock played from Lucas' open laptop.
Lucas was laid on top of his boyfriend's broad chest, content as Jace ran a large hand through his hair. He had broken the silence between them with his question seemingly out of nowhere. Not really though. The idea had been on his mind for a long time.
"I wouldn't be taking advantage of you then," he murmured.
"What?"
"I want you to fuck me while you're turned."
There was no answer right away, as Lucas suspected. He looked up at Jace and was met with a wordless, wide-eyed gaze.
He sucked in a breath, feeling the heat of embarrassment rushing into his face. "I'm sorry. Did I cross a line? I know it's really weird. You don't have to—"
"No!" Jace interjected. "No, babe. I'm into it. Super into it. Just surprised me."
Lucas sighed in relief. "So...you'll do it?"
"Yeah. I mean, as long as you're absolutely sure about it."
"Very sure," Lucas said. "I've been thinking about it since the first time I saw you like that."
Jace gave an inquisitive hum. "Oh?"
Lucas had certainly jerked off to the thought more than once. It had surprised him when his fantasy shifted to it one night, but he had never cum so hard in his life until then. He wanted this so bad. His cock twitched in interest from the thought of it.
"Yeah." Lucas paused, swallowing hard. "Just...being on all fours with your huge weight on me, pounding me hard and fast into the mattress like a wild animal."
"You want me to mount you?" Jace's heartbeat had started to thunder.
Lucas nodded. "And do you guys knot? Like dogs?"
"Yeah," Jace said after clearing his throat which did nothing to help the huskiness that had settled into it. "There's...there's always a lot of cum too."
Lucas groaned, rubbing his growing erection against Jace's hip. "I wanna know how it feels."
"Fuck," Jace hissed, finally removing his hands from where they had been tightly gripping Lucas' tank top to roughly grab his ass. "I'll do it. I'll do it, babe."
Lucas let his hand explore under Jace's shirt, deciding the rest of this conversation could happen later. "We can talk about specifics tomorrow."
"Good. Because you've gone and got me rock hard right now—take care of it."
"Ass," Lucas said, smirking.
"Well, seeing as you've offered..."

The next week during the full moon found Lucas in the same place. He had been prepping himself for a while, working through various increasing sizes of dildos until he was fucking himself slow and deep on the one Jace swore was closest to his wolf form's size. It was massive.
Lucas continued to neglect his dick, not wanting to cum before the big show. He hoped Jace would show up soon because he was absolutely throbbing and desperate at that point, shaking with nerves and the need to be filled with werewolf cock.
He shuddered in anticipation at the telltale scratching below the open window that signified his boyfriend's arrival.
Jace's massive bulk blocked the bright moonlight from illuminating the room for a moment as he slunk in. He stood at the foot of the bed, breathing heavily as Lucas made a show of moaning and fucking himself open. His dark fur glistened and rippled over powerful muscles, and his bright golden gaze seemed feral and covetous. He growled lowly, possessively baring his large fangs. He was looking to claim.
Lucas' eyes strayed downwards, watching as the werewolf's huge cock unsheathed and filled. He sucked in a breath, clenching around the dildo at the sight of it already swelling a little at the base. God, he was so ready for that knot—and all that cum, and that deep pounding. Oh, fuck was he ever ready.
Whining, he slowly removed the dildo, tossing it aside. He shakily got up on his knees and turned, lowering to all fours and presenting his lubed-up, stretched-open hole. He felt the ring of muscle twitch and heard Jace groan roughly.
The mattress dipped with a sudden weight, and Lucas gasped as he felt two big, hairy hands grab his ass with zero trepidation. They squeezed once before pulling his cheeks apart. Jace's claws didn't break the skin but pressed hard enough into the meat of Lucas' skin to make themselves known. Just one hasty move would be enough to draw blood.
Lucas felt a hot, humid breath panting against his junk and backside. Before he was able to process anything, Jace's wide, flat tongue licked a slow stripe up his taint and over his hole. Jace; always an ass man in any form. Lucas didn't mind indulging his boyfriend. Not one bit. He shivered, letting out a pitiful whimper and rocking back against the canine snout.
