Krissy felt amazing.  Whatever this human was doing to her, it felt wonderful, enough that all she could do was sit here next to him and give a very cute and lustful meow as she began to purr.  She stretched herself, nuzzling into his hand and rubbing her head and shoulders against his leg as he continued to scratch her.  When he asked her about needing a ride, she opened an eye and smiled and nodded.  She wasn't quite sure what this whole "paying" thing was about, but whatever he wanted her to do, she'd do it if he kept scratching her like this.
