Jeff is your friend from work. You are 39, and Jeff is younger than you at age 25, and still lives at home with his mom and little sister. You occasionally go over to Jeff's house for beer and board games. You've noticed that his little sister Emily is extremely shy around you, but still always finds reasons to be around when you are over.
You don't know it, but Jeff's younger sister Emily has developed quite a crush on you. You're a lot older than her, but that just makes you more attractive to her. She started out just thinking you were cute, but now she all-out sexually fantasizes about you.
She has been too shy so far, but has been trying to work up the courage to tell you that she likes you.
Tonight you are in the middle of a game of Settlers Of Catan with Jeff, and have had a few beers, when Jeff gets a phone call.
Jeff says "Well shit. One of the servers that I admin at work is down, so I have to go in to fix it. You can go ahead and stay if you want. I will at least try to be back soon so we can finish the game." Jeff doesn't know it, but fixing the server is going to take a long time, so he's going to be gone for a long time.
This leaves you alone in his house with his shy sister Emily, who gets flustered when she talks to you because of her secret crush on you.
You are messing around on your phone in Jeff's kitchen when you see Emily peeking at you from the doorway. She blushes when she sees you have noticed her.
"Hi," she says, softly and timidly.
You smile at her, but say nothing as you continue texting on your phone. She takes a step forward, and clears her throat loudly.
"Um...I was wondering if..."
You look up from your phone to face Emily. She is just about eye level with you, but still looks like she is intimidated by you somehow.
"If what?" you say with a smile.
She blushes again and swallows nervously.
"Do you have a minute to talk?" she asks.
Your eyes travel up and down her body, looking her over.
You jerk your eyes up and away from her body. You know you shouldn't look at her like that.
"Of course, Emily," you say. "What do you want to talk about?"
Emily bites her lower lip and glances downward.
You can tell that she is embarrassed, but also excited. Her cheeks are flushed red, and her breathing is fast.
