Derek hadn’t meant that Bitty needed to take his clothes off right now, but he doesn’t try to stop him. Bitty grew up playing sports, and Derek remembers that locker room mentality. Still, he has to resist the urge to let his gaze sweep over Bitty’s body curiously. And okay, he fails.

Bitty is small, but he’s all lean, compact muscle. He has strong thighs and an ass that Derek has admittedly already stared at through his tight pants a time or two. His glance is fleeting, and too quick for Bitty to even notice, and then he starts removing his own clothes.

Once they’re both naked, Derek gestures at the vial, anticipation running through him. “Okay, go ahead. I’ll shift when you do.”
