Derek practically shouts when Barry's fingers wrap around his cock, and that's even before they start to vibrate. He's utterly helpless and he doesn't even care as he buries his face into the curve of Barry's neck. He feels completely owned by Barry in that moment, unable to focus on anything that isn't him or how his own body responds to him. It actually feels like a gift to have his control lifted from him however temporarily by someone that he trusts so well.

He's had control ripped from him so many times, but with Barry it's different. With Barry, it's freely given and Derek doesn't have to think about anything. There's just this, only this.

It only takes a few strokes of Barry's buzzing fingers before Derek comes with a helpless yelp, slicking Barry's fist as his orgasm rockets through him. He's gasping for air by the time that it's over and he reaches up to cling to the back of Barry's neck just to keep himself grounded because for one wild moment, it feels like he might float away.

"I've never felt like this before," Derek pants out just before licking a bead of sweat from the line of Barry's jaw. "Fuck, it's good. Please, Barry."

He doesn't even know what he's asking for at this point. All he knows is that he wants more.
