After we ate dinner that Friday night, my wife wanted to take everyone out for some ice cream. Her daughter Zoe said she was a little tired and didn't want the extra calories so she said she would pass. I said that I would clean up the kitchen from the dinner that I prepared. But Zack wanted some ice cream, so my wife and Zack left to get some.
Zoe said she would help me clean up the kitchen while they were gone. While were standing at the sink washing the pots and pans, I said something to Zoe, "I need to tell you something that might upset you."
She answered, "Okay, what is it?" As she had a puzzled look on her face.
I said, "This afternoon when I first came home, I saw you and Zack in the bedroom, and you giving Zack a blow job."
Zoe gasped, "You saw us?!"
I said, "Yes."
Zoe turned red and said, "Please don't tell anyone what you saw." "I know it's totally wrong and disgusting."
I said, "I won't tell anyone, I promise." "But, I'm concerned about Zack though."
Zoe said, "I know what you're thinking, and you should be concerned, but we've discussed this with ourselves and Zack is a bright and level headed 18 year old and understands the complexity of the situation."
I asked, "Are you sure he knows the taboo nature of this relationship?"
Zoe said, "Yes, he understands." "We've talked for hours about how this has happened, and what could happen, good and bad."
I said, "Ooookay!"
So, with that put out there, Zoe asks me, "So how long did you watch, and what did you think?"
I stammered and said, "Well..., I watched till the end when he came in your mouth and you swallowed his load."
Zoe said, "Well what did you think?"
I thought to myself, "I got so turned on that I started jacking off." But, I said, "Zack has a pretty big cock." Then chuckled.
Zoe said, "Yes he does, doesn't he."
Then I said, "To be truthful, I was totally shocked, but at the same time, I was turned on."
Zoe said, "I've always had this thought in my head, that if you want to have sex with anyone, and they're up for it, why not do it, no matter who they are."
I said, "Interesting philosophy, I didn't take you as being that adventurous and disturbing."
Zoe said, "Take you for instance, even if you're married to my mom, and we decided to have sex, I would do it, in secrecy of course."
I said, "You would?"
She said, "Yes!" "Do you want to have sex with me?!"
I blushed and opened my mouth agape and didn't know what to say. I've known Zoe since she was 16 years old when she was pregnant with Zack. I've only seen her as Zozo, my wife's daughter. Sure, she is hot looking and sexy, but I've never had any inkling of having sex with her.
I said, "I don't think that would be a good idea."
She said, "Why not, you don't find me attractive?"
I said, "It's not that, you're hot and sexy!" "But, you're my stepdaughter."
She said, "So what, we're not even blood related or legally attached."
I said, "I couldn't do this to your mom."
She said, "What she doesn't know won't hurt her."
I said, "There you go again with your own philosophy."
