It’s your turn to join in with Isabella and her brother

Emma gets up and moves back to you and gives you a big kiss. You enjoy the familiar taste of Isabella’s pussy on Emma’s mouth.

Isabella turns around again - and now facing her brother, leans in and kisses him passionately.

You break away from Emma, grab some lube from Isabella’s nightstand and get behind the brother and sister. You begin to run a lubed finger in Isabella’s ass. You know she wore an anal plug all day in anticipation of this moment, so it doesn’t take long to stretch her out - even considering how big you are.

Isabella’s brother, so caught up in kissing his sister, doesn’t even realizing what you’re doing until you’re fully inside Isabella’s ass.

He suddenly looks up and sees you standing behind his sister - joined in their fucking.

“Are you… are you in her ass?” he asks in disbelief.

“Yeah, it’s so tight. Didn’t you know your sister was an anal slut?” you say smiling.

Her brother can’t find the words to respond before Isabella second’s what you said.

“It’s true. I really love it up the ass,” she says as she’s being taken in both holes. “Does your wife like anal, Uncle Daddy? Does my big brother fuck my sister-in-law up her tight ass?”

“Definitely not!” he says, getting more into this experience. He’s sorta always wanted to have a threesome with two girls. He’s happily share his wife, if there was a chance in hell she’d do it (she wouldn’t he knows) - but sharing his sister… well that’s just next level exciting.
