Isabella says, "Let's go see what Emma and Jacob are up to!"

You expect Isabella to thank you for the powerful orgasm you gave her and perhaps then offer to return the favor, but instead she just stands up and says, "Let's go see what Emma and Jacob are up to!"

Isabella starts toward the bedroom before you can respond, so you quickly get up too and follow her there.

Isabella opens the bedroom door and the two of you enter. Not surprisingly Emma and Jacob are on the bed fucking like crazy. Emma is on top, riding him with her back turned towards you and Isabella. They both turn to look and actually greet you though.

"Round two," Emma says enthusiastically and then continues to give her full attention to Jacob.

"Isn't that hot?" Isabella says to you. "I honestly can't believe you still have your cock in your pants. I'd be jerking off if I were you."

Indeed you felt a bit dumb still being fully dressed while your girlfriend and Jacob were fully nude, and Isabella was just barely still wearing her dress (which was now soaked from her pussy juices). So you take your clothes off and start jerking off as you watch Emma ride cock.
