She's right that this is personal. Probably the most personal thing Loki has ever done. It's not that she's the first to fuck him, but she is the first that he's truly let in. All his other encounters before her, he'd always held back, not let them really see how he felt and what he desired. These are things he can't hide from her though, and he wouldn't want to even if he could. Not only does he want Natasha to be able to see all of him, he needs it too.

He can hear her talking, her words seeping into him making him almost desperate for more. He tries to reply, but his words come out as a deep moan before he actually gets enough of his wits together to attempt an answer. "You are perfect just as you are. This is perfect, far better than I deserve and more than I ever could've asked for." His words come out in fits and starts as he gasps for breath, his hips grinding back against the invasion of her fingers, but he does finally get the words out.

Loki's whole body shivers in pleasure as she uses her own juices to continue to lube him. He feels his balls tighten, his body ready to release just from her telling him. "Please," he manages to gasp out as his hips rock back and forth between her fingers and the pillow, desperate for more friction.
