They meet

Mrs. Incredible slides the guard's cock into her.

"Mmph!" Mrs. Incredible moans as she starts to move her hips.

"Oh, yeah! Shit!" The guard moans.

Mrs. Incredible puts her hand over his mouth. "Quiet, I'm trying to enjoy this." She then starts to go faster on the man's cock.

Meanwhile,

Pia looks around and hears moaning a further down the hallway.

She goes further and peers behind a corner and see two people fucking.

Pia has to admit, she was kinda turn on by what she is seeing. Now she has to decide if she should just watch or join in.
