Aiden stared down at her and saw her cheeks turning red. She looked like a little bunny who was looking here and there, trying to find an escape.

"Sure about what?" 

His smirk deepened and he slowly leaned down, closer to her ears to whisper. "Are you sure you don't need a stronger reminder that will not let you forget it at all? If you want, I can give it to you always." Saying that, he didn't even give her a moment to think and bit her ear, making her gasp. "Something like this."
