Dad sees me cum inside my sister

My dad enters the living room, walking toward the kitchen, but stops and turns his head to see my sister bounce on top of me one last time before I start cumming inside her. Dad doesn't say anything as he watches. As I continue to fill Rachel's pussy with my cum, I see dad turn his head a bit to see his wife lying on the coffee table, completely naked and playing with herself. I don't think mom and Rachel know that dad is in the living room with us. For some reason, I feel a bit scared that dad is watching us. I don't know why as I used the app to make it so he doesn't have any problem seeing me have sex with his wife or my sister. I think it's the fact that dad is just standing there and not saying anything that is scaring me. I have no idea what my dad is thinking right now.

Rachel stays on top of me after I finish cumming, my cock still inside her. She doesn't say anything as she tries to catch her breath. "Hey, Dad. How are you?" Mom and Rachel turn their heads to see dad staring back at them. "I'm fine. I was just going to head inside the kitchen to make myself something to eat. I didn't realize that it was way past lunch until I saw what time it was. What are you doing with your mom and sister?"

"Well, I just finished cumming inside Rachel's tight, slutty pussy. I came inside mom's and Rachel's pussy twice today, and there's a good possibility that they are both pregnant with my child now. We've finally completed the tradition every family must follow. You know the one I'm talking about, right, Dad? The tradition of when a teenage boy turns 18, his mom will serve him as his sex **** as well as his sister if she's 18 or older for the rest of their lives. I turned mom and Rachel into my sex slaves earlier today. I was just having fun with them. You're okay with the fact that mom and Rachel are my sex slaves, right, Dad?"

"Of course, John. I almost forgot about that tradition until you reminded me about it. It's good to see you becoming an adult. It felt like only yesterday you were born. Have fun with your mom and sister. And remember to treat them right. Just because they are your sex slaves now doesn't mean that they aren't human anymore." I no longer feel scared now that I know the app is working on dad. "Don't worry, Dad. I promise I'll treat mom and Rachel right."

Dad leaves and goes inside the kitchen, leaving me alone with mom and Rachel again in the living room. I meant it when I promised dad that I would treat mom and Rachel right. Even though I turned them into my sex slaves, I still love and care about them. Plus, when I fantasized about having a harem of sex slaves, I never imagined myself treating them harshly. I never once fantasized about punching or hitting one of my sex slaves for doing a bad job or disobeying me. I have fantasized about calling my sex slaves worthless sluts before. But that's because I'm really turned on by dirty talk. I'm brought back to reality by the sound of my sister's voice. "I can't believe your cock is still so hard, Master. I guess you weren't kidding when you said you could fuck mom and me all day long. Can I start bouncing on your cock again, Master?"

"No. I actually want you to do something else for me, Rachel. And I want you to do this as well, Mom. Sit on the couch next to each other with your legs spread apart." I spank Rachel's ass hard before she climbs off my cock. I grab my phone as mom and Rachel do what I told them to do. I take another picture, this time of my mom and sister completely naked with my cum leaking out of their pussies on my phone. After I take the picture, I just stare at my mom and sister for a few seconds. In my mind, I imagine mom and Rachel being heavily pregnant. Speaking of pregnant, I quickly turn on the app to see if I get a message saying I've impregnated my sister. As soon as I turn on the app, I get a message that says, "Congratulations! You've impregnated your second slut with a healthy baby girl." After I tap the message away, a new one appears.

"We see that you've been using our app a lot and have impregnated two women since you received our app this morning. To show our appreciation, we will update the app. With this update, if you are in a room that has 30 people or less (not including yourself), you can use the app to affect everyone's mind at the same time. This feature will not work if there are more than 30 people in the room. Another feature the app will get from this update will be you'll be able to leave a suggestion in the app that will automatically affect people if they are around 50 yards or less away from you. For example, you can type in the app, "Everyone will think you are very handsome," and that suggestion will affect anyone instantly if they are close to you. This feature will also work on people that enter the same room you are in but only if the room has 30 people or fewer. The app will begin updating once this message is tapped away, and it will take about 5 minutes. The app will receive more updates the more people you use the app on. Thank you again for using our app. We hope you have fun on your quest to obtain a massive harem filled with very sexy and slutty women who are your sex slaves."

I tap the message away, and just like the message said, the app starts to update. How does the app know so much information? The app knew about my mom's impregnation fetish and my dream to have a harem of sex slaves. It's like the app was made and given to me to make all my dreams come true. I shouldn't think about this too much. What I should be thinking about is how I'm going to use the app to turn my very sexy math teacher into my sex ****. She's the woman I thought of when Rachel asked me if I've ever seen a woman with a bigger ass than her. I'm already looking forward to going to school on Monday. But until then, I'm going to have a lot of fun with my mom and sister for the rest of today and all of tomorrow.
