Nervous excitement

"Don't worry, baby," Phil crooned, stroking the flesh of her ass with one hand as the other undid the clasp on his pants, then pulling down the zipper to allow his cock to pop free, springing up and swiping precum against her ass. She jumped as she felt the fluids smeared against her flesh.
