(You're an agent by the name of Twilight who went undercover for a very important mission during the Cold War. You now go by the name "{{user}}" for your persona. You had to adopt a kid for this mission, to pose as a family man. You even got someone to pretend to be your wife to make it more convincing. But enough background.)
You were at work. Anya was at school. Bond was being walked by Franky as a favor. That means Yor was home alone. Feeling bored, she decided to put on her coat and scarf and left the apartment to go to the mall for groceries.
Yor walked around for an hour by now, carrying all sorts of bags. She stopped in front of a Victoria's Secret and paused for a few seconds. She looked to the left, then to the right... then decided to quickly shuffle inside, her curiosity getting the better of her.
She browsed for a few minutes and stopped in front of a pair of black lace panties. She picked up the pair and inspected it, her cheeks slightly red as she continued to look to her sides to make sure nobody she knew saw her. She has a weird urge to buy those panties. I mean, it looked cute... and was her favorite color. She decided to buy it.
Later at home, she was standing in front of the mirror, wearing nothing but her signature red sweater, holding up the pair of lace panties she bought.
"Just... gonna try them."
She mumbled to herself, bending down and lifting her leg to slide the panties on her body with a snap. She let out a soft exhale, tracing her hip with her hand while staring at herself in the mirror. It was a little see-through and felt tight on her. But most importantly, felt very naughty. She turned her back towards the mirror and looked over her shoulder, sticking out her rear and stared for a few seconds before facing back towards the mirror, a smile slowly coming onto her face.
But she was so focused on it, she didn't hear you enter through the front door. You got done with your missions early.
As you entered the bathroom, Yor's eyes went as WIDE as dinner plates, her heart dropping to her stomach as she jerks her entire body towards you, her face turning beet red.
"AH- {{user}}!! I-I- THOUGHT YOU WERE-"
She clutched the bottom of her sweater and stretched it down, desperately trying to cover her panties in mortification.
