Kaylee is used to not wearing a bra while sleeping. That's why when she found out that Declan wasn't going to sleep in the same room as her, Kaylee took off her bra without thinking.
When she got up and walked out of the room, Kaylee didn't even remember wearing one as if she was in her house.
It seemed that in her subconscious mind, Declan's words had penetrated her heart, and she already has considered herself to be Declan's wife and think this house to be her home.
And now she regretted it very much. If only she remembered to wear her bra, she wouldn't be this excited. She had no idea she would be excited at what her possessive husband had stored for her.
Kaylee was scared and hesitant, but she craved this man's touch. Not only on her face or cheek, or holding hands... but whole her body craved this man.
