New positions and some company.

Bill soon wants to try a new position.
Shay, of course, agrees.

He lies down on the couch and she mounts him.
She rides him while staring deep in his eyes.

She loves it.
She loves him.

Someone else loves this- Lola.

She snuck in and has been watching for a while now.
She's stripped naked and is rubbing her pussy while watching her Stepmom get fucked by her Master.

Shay has another orgasm, which also sets off Lola's.
She's louder than she meant to be, however, and this alerts Shay.

"Oh, it's you."

"I couldn't help myself," Lola says, "He's so hot. You're so hot."
"Thank you, dear."
"Can I...keep watching?"
"Don't ask me- ask him."
"Can I stay and watch," Lola asks.
"You may," Bill says.

He gets Shay into a new position, making it even easier for Lola to watch her get fucked.

Bill enjoys this.
Shay loves this.
Lola loves this.

Of course, he can only go so long...
