Surprised

Sandy is shocked, and is about to call out for someone, but her reaction is short lived as you kiss her on the lips. The virus does its work, at least mentally as she relaxes, the physical changes would come later.

"Mmm, Casey, I want you to lick my pussy so badly..." Sandy says, and you are happy to oblige, kneeling down you run your tongue lightly across her pussy.

She would be your first conquest, and you wanted to savor it as long as possible.
