This is unraveling faster than a hyper kid's roll of wrapping paper!
According to the source, the two were "kissing like crazy" immediately! Crazy!! Heat!!!
You see… K-Stew was heading home from the gym that day when she received a call, prompting her to turn around and head to the west side.
When she finally arrived at her destination, the photographer wondered why she'd be so antsy to reach an abandoned building with "FOR LEASE" signs everywhere.
The source continues explaining their dirty romp, saying:
"They'd only take a break whenever someone walked by. It seemed like they couldn't get enough of each other. She was swept up in the moment."
Eventually, Rupert seemed a little nervous so the two finally left.
WOW!! TALK ABOUT SEXUAL TENSION!!
And poor Liberty Ross!!! And their kids!!!
These two just opened a whole Pandora's Box of hurt!
