...standing by the restroom entrance, talking to a man

You don't recognize him, but you can see from here he's quite handsome and obviously trying to chat Alice up. You're completely unsurprised, Alice gets hit on all the time and she looks great tonight, but she's usually quick to let men know she's unavailable and capable of fending off unwanted advances on her own. This time, though...

...you can't really tell from here...

...but it looks like she's flirting back. You look again, and watch for a minute.

She's smiling at him, pivoting playfully on the balls of her feet. She just laughed at a joke, and touched his arm. She has her arms in front of her, she's definitely pushing her breasts together now and doing her little knee-bob, leaning forward ever so slightly which you're sure would give the man a quick look down the front of her dress. You could swear you just saw her tilt her head to one side and smile, biting her lower lip as she listens to something he said.

Yeah, she's flirting with this guy. There's no question about it. And she's laying it on thick, too.

You feel a rush of adrenaline, you can't tell if it's anger, jealousy, or what, but it's definitely tinged with a strong dose of arousal. You think back to that porno you caught her watching, is this her idea of getting petty ****? She has to know you can see her plain as day, she's practically broadcasting it. Your face flushes and you feel a bit faint, and you know you have to do something about this...but what?
