Things are heating up on Pretty Little Liars.

In a sneak peek from Tuesday's all new episode, Aria (Lucy Hale) decides to surprise her much-older boyfriend Ezra (Ian Harding) with a sexy midday romp.

After seductively removing her leather jacket, Aria says, "I've been thinking that we could use some alone time."

Unable to lock Ezra's office door, Aria pushes a chair in front of it before removing her top. "I have class in 15 minutes," Ezra says, pulling away.

"That's plenty of time," Aria responds before going in for another kiss.

Pretty Little Liars airs Tuesday at 8 p.m. (EST) on ABC Family.
