Fuck her from behind

"Then turn around."

She does and you push into her from behind.

"Ahhhh...."

You continue to move back and forth as she holds onto the cistern for support.

"Don't stop."

You're having a hard time getting into this as your dick is sort of dying from all the pussy it's been in, but Monica's enthusiasm is enough to get you through.

"Ah....shit."

You start to lose your rhythm as you feel yourself release inside her. Monica looks over her shoulder at you and smiles.

"It was my pleasure."

She turns around and walks into the bedroom. A moment later you fall onto the bed next to her.

"I'm wiped."

She curls up and you spoon with her.

"Thank you."

"For what?"

"For tonight, for being so nice to me when you didn't have to be."

"You're welcome."

You slowly drift off to sleep.
