Nanami exhales roughly and takes a few more breaths, even after Haibara pulls back. He looks down to meet Haibara's gaze, and that alone is enough to elicit a small groan.

"I—" Nanami tries to think of something besides 'both' because he wants both. He wants it all. It would be harder, if Haibara managed to ask through the bond, while still taking him in his mouth. "Yes."

He gently pulls Haibara up and kisses him. He rocks his hips against Haibara and presses back against the finger in so doing. He just wants him.
