Join in

Katie can't resist it any longer, she lies down next to Lisa. "Mind if I join you, Lisa?" She asks, her pussy getting a little wet.

"Yes, please do," Lisa says, fingering her pussy harder.

Katie starts to reach for her own pussy, but Lisa grabs her hand to stop her, and moves it to her own pussy. "Fuck me, Katie, I want you to finger fuck me."

Before Katie can say anything, Lisa kisses her passionately.

What will Katie do now?
