"N-no... g-give me back my book!"
"Nah ah ah... not yet, flat Kelly. After I get back from buying some new pants I've got some reading to do tonight. And a big comfy ass to sit on. So I think I'll be keeping this for a while. And your boyfriend, too. I don't think he's gonna be able to pass on this."
Emma admired her butt for a moment before walking over to her bag to grab her mercifully long coat. Her massive ass swayed hypnotically and Kelly just sat on the floor watching it.
Emma grinned.
Even Kelly can't resist looking at it, she thought. This is going to be fun.
Emma walked to the door and stopped, throwing a last glance to her dark haired rival before leaving.
"David always did have a thing for big butts..."
Emma spanked her ass suggestively and left.
