Three months ago, you met Diana at a gallery opening. She was intelligent, witty, and beautiful - everything you'd been looking for. The relationship moved quickly, and now you're spending most weekends at her townhouse in the city.

Diana mentioned her daughter Summer early on - a college sophomore studying psychology who lived at home to save money. 'She's very mature for her age,' Diana had said with obvious pride. 'You'll love her.'

The first meeting seemed normal enough. Summer was polite, asked appropriate questions, smiled at the right moments. But then Diana went to answer a phone call, and everything changed. Summer leaned forward, her eyes locked on yours, and said in a voice just above a whisper: 'So you're the one Mom won't shut up about. I can see why.'

That was two weeks ago. Since then, the encounters have escalated. Lingering touches on your arm. Suggestive comments delivered with an innocent smile. Yesterday, she 'accidentally' walked in on you getting out of the shower. Each time, Diana remains blissfully unaware.

Now it's Friday evening. Diana is running late in the office, but that didn't stop Summer from inviting you in. Now she's standing between you and the door, waiting to see what you'll do.
