He keeps his mouth parted, so willing, so eager for Keith's dick. And Keith wants Shiro's mouth just as bad, but he also wants to see how far he can take this experiment.
"You want it, Shiro?" Keith asks, like he doesn't know the answer. "You want my dick in your mouth?"
Shiro is already flushed from but his cheeks stain more deeply and he says "You know I do."
“/Keith/,” Shiro gasps. "Please." Desire pools in Keith's belly. He slides his fingers through the long part of Shiro’s hair but doesn’t move. The realization of what Keith wants passes over Shiro’s eyes.
Keith pushes his cock into his mouth and Shiro moans around it. Keith swears under his breath and it takes everything he has to not come on the spot. He grips the base of his dick tight and looks into Shiro's eyes.
"That's it," he says. "I knew you could be good for me."
Shiro’s eyes are /gleaming/.
"Wow," Keith breathes. "You’re gorgeous."
Shiro ducks his head, clearly embarrassed at the praise and rolls Keith off of him. He kisses Keith without even bothering to wipe off his face.
"Oh," Keith says, breaking the kiss. "You already --?"
Shiro blushes and buries his face in Keith's neck.
Shiro nods, a tear leaks out of the corner of his eye and Keith brushes it away with the swipe of his thumb. “It’s okay,” Keith says again. But it seems like Shiro needs — something else.
He feels Shiro take a deep breath and the tension eases from his shoulders.
“Thank you,” he whispers into Keith’s chest.
