Summary
"Relax, I ain't here to hurt ya, not when you're smelling this good. Damn, is this what you smell like on the daily, or is this just for me?" He asked, leaning in to sniff deeply at William's neck, who was now also able to smell him back. This alpha was like wind, like freedom, like bad decisions that took you in the moment and never gave you back.
Mohawk pulled back and William saw his eyes slit and change into a liquid golden color, and William had no doubt his own eyes mirrored that look. Shit.
They were true mates.
"Oh?" Mohawk smiled wide, sharp canines glinting. "It is just for me, isn't it?" He let out an uninhibited laugh and William was floored. This was his True Mate? The person who would complete him? This couldn't be right.
But he relaxed almost against his will, the scent the other pumped out raw and feeling so much like a dream, he swayed on his feet a little. Oh, right.
He was nearing his heat.

Summary
And, look, William had a thing for begging, okay? Mark was hitting his hot spots— neck, waist, groin, whispering and begging— it was sexy and scary. Scexy? Sery? Something. And it wasn't like he had never fantasized about his friend, even though that one time was an accident and had never been repeated; Mark was hot and William was horny.
Can you really blame him for wanting this?

Summary
He waited impatiently then opened his eyes slowly, holding his body still in the same pose. Eyes fully opened, he gaped at the sight of his arm; it was like there were sequins or tiny crystals embedded in his arm, pearlescent and glittery. There was… they were…
"Scales," William breathed out. Indeed, they were soft and flexible as he twisted his arm to look at it. "How did this… this wasn't…" William tried, forming half-thoughts at the sudden insanity that was now his life. He knew what he would find if he looked down, and indeed, he found a goddamn mermaid tail.

Summary
William lived a pretty normal life, or as normal as one could get when you had a superhero as a best friend and a cyborg for a boyfriend.
Until an alternate version of said best friend comes crawling through his window with a plan to protect him, no matter anyone else’s opinion. Even William’s.

Mark seemed to deflate at that, and had tears of his own in his eyes. "I'm sorry you feel that way and that I messed all this up," he whispered. "I just wanted to save someone like him. Someone like you.“Series
