You have to!

Without spending too much time thinking about what you're planning on doing, you delete the number from your roommates phone and return it to him before heading back out to your car. You pull up to the house within fifteen minutes and park in the driveway. After all, it's your dad's house, there's nothing strange about your car being there. You still have a key and let yourself into the house calling out "Hello?" as you close the door behind you and begin walking down the hall towards the kitchen.

Emma's voice calls out from the opposite side of the house. "Hello? Who's there?" You can hear her heels clicking on the wood floor as she makes her way down the hallway, then stops in her tracks when she sees you standing in the kitchen. A look of fear flashes across her face that she quickly covers up with a smile. "David! What a surprise! What are you doing here?"

Emma looks stunning and has obviously made herself up in anticipation of your, or you should say, "Mike's" arrival. She has her long, blonde hair down, framing her oval shaped face, and dimples appear in her cheeks while her blue eyes sparkle when she smiles at you. Her lips shine with a light, rose lip gloss and she's wearing a black, clingy dress with a sweatheart neckline that hugs her enhanced breasts, sits tight against her flat stomach, and stops mid thigh.

"Hi Emma, is my dad around?"

"Oh, no honey, he's not. I wish you had called, I could have saved you the trip over." she says to you, glancing over your shoulder towards the door.

You move towards her and embrace her in a hug, letting it linger a moment longer than typical, enjoying the feeling of the heat of her body and the fullness of her breasts against your chest and letting the growing bulge in your pants press against her. Taking a step back, you keep your hands on her shoulders and smile at her. "That's ok Emma, I was in the neighborhood and figured I'd swing by. It's still nice to see you, especially in that outfit. You look incredible! Are you going somewhere?" you ask her, knowing full well she's expecting "Mike" to be there any minute.

"Umm... Going somewhere? No, nowhere special. Just some errands to run." she stammers out, trying to come up with a reason she's dressed the way she is.

"Wow, you really get dressed up to run errands! Actually, I'm kinda glad my dad's not around. I thought maybe we could sit for a minute and talk." you say moving around her to the opposite side of the counter. "You've been married to my dad for, what, eight, nine years? But I still don't feel like I know you that well." You move towards the wine bar and pour two glasses before she has a chance to object.

Emma can tell she's not going to be able to get rid of you that easily, so she figures the best thing to do is indulge you this little talk and hope that "Mike" is late. She sits at the island and takes her glass from you, trying to keep the look of annoyance off her face. "OK, I guess I have a little time. So what do you want to talk about?"

"Oh, I don't know. Why don't you tell me what you like to do in your free time." you say moving around the counter to sit next to her. "I mean, I know you work out all the time. Just looking at that hot, tight body, I can tell you put in a lot of hours at the gym." you tell her, making it obvious that you're ogling her body. "But what do you like to do when you're not at the gym?"

Your comments seem to have made her flustered and she shifts in her chair, unsure how she should take your compliment. She takes a deep drink from her glass before answering you. "Well, you already know your father and I like to travel. And when we're not traveling, I stay busy with volunteer work. Nothing too exciting really."

Enjoying watching her get flustered, you decide to push the envelope a little more and lean closer to her. "Speaking of my dad, I have to ask, what made you want to marry him? Now don't get me wrong, I think he's a great guy, but you're way out of his league."

Not sure if that's a compliment for her or an insult to your dad, Emma decides to answer your question as tactfully as possible. "David, you get to a point in life where what matters more is how a person treats you and how well you get along. I was with plenty of assholes before your father, and when I met him and noticed how well he treated me, I knew that he was the one for me."

If you didn't know how much she was cheating on your dad, you might have bought her story, with how well she delivered it. But you do know and decide to call her out on it. "Yeah, I get that, but hear me out on this one. See, my buddies and I have a theory. Are you familiar with a 10-point grading scale for looks?"

Not sure if she wants you to continue, Emma answers you with a hesitant "Yeah..."

"Great." you continue. "So the way we see it, all things being equal, people will only hook up with those people that are within two spots from them. If you're a "six", you could get anyone from a "four" to an "eight". Are you following?"

"Yes" she replies, resigned to the fact that she needs to let you continue.

"Good. Now not all things are equal of course. You can gain or lose points based on other things. A good personality will move you up, money of course, and some other things can factor in. So, getting back to you and my dad, I'm doing the math, and things still don't add up. I'd rate you a "ten", but for arguments sake, let's say you're a "nine". My dad is more like a "four". So at best, he should be able to get a "six", a "seven" if we give him points for personality. So my question to you is how'd he bridge the gap? Is it his money? Does he have a big dick? What is it?"

Emma was letting this play out, but has had enough at this point. "David, I don't know what's gotten into you, but I think it's best if you leave." she says, standing up from her seat.

"Aww, but Emma, I just got here. Didn't you invite me over to keep you company?" you ask her, grabbing hold of her wrist before she can get away.

"What are you talking about? You just showed up here. Are you on something?!" she asks, a look of confusion on her face.

"Ooooh, that's right, I forgot to tell you when I got here. I'm Mike. I called just a little while ago, said I got your name from Lisa, you told me you were lonely and wanted company... Does that sound familiar now?"

Emma's face drops as her mind spins trying to come up with an explanation she can give you, but all she can do is stand there with her mouth agape as she comes up with nothing.

"Now Emma, this can work one of two ways. I can tell my dad all about what you've been up to behind his back, or..." you make a show of unfastening your pants in front of her, then smile and make eye contact with her "...we can do what you had originally planned on doing this afternoon with Mike."

Emma knows she's been caught and can't think of any other way out of this. Reluctantly agreeing to your request, she asks for reassurance that your dad won't find out. "OK, fine, but you'll promise me you're father won't find out about this, or any of my other activities, if I do this with you?

You had hoped this would work, but didn't know it would be this easy. Your cock starts to harden and a devilish smile breaks out across your face. "I promise Emma. Your little secret will be safe with me."

"Fine. Let's get this over with then. What do you want to do?"
