Have a threesome with my mom and sister

It looks like I'm about to make another one of my fantasies come true. I'm going to have a threesome with my own mom and sister. "Mom is right, Rachel. I just finished fucking you. It's her turn now. Lay down on the coffee table and spread your legs for me, Mom." Mom finally stops playing with herself as she lies down on the coffee table facing me. I place my phone on the couch behind me, making sure I put it in a spot where it won't accidentally fall on the floor. I quickly check to see what time it is by looking at the clock underneath the TV. It's currently 1:22. I'm going to keep checking the time while I'm fucking mom, as I don't want to make Rachel wait an hour for me to fuck her again. I think I'll fuck mom for somewhere between 15 to 20 minutes before I decide to make myself cum. Perhaps I might even go for half an hour. As I start to line my cock up with mom's pussy, Rachel says, "I hope your cock is still hard after you cum inside mom. I really want you to fuck and cum inside my tight, slutty pussy again, Master."

"Don't worry, Rachel. I have plenty of cum to give to both you and mom. I feel like I could fuck you two all day long. And I promise I'll fuck you again as soon as I finish cumming inside mom." I did give myself unlimited stamina and an unlimited supply of cum using the app earlier. I don't feel the least bit tired despite having sex for over two hours and cumming twice already today. I quickly grab mom's breasts as I insert my cock inside her pussy. Just like last time, I'm easily able to slide my entire cock inside mom's pussy. Mom instantly starts to let out loud moans as I begin thrusting. "I saw that you've been playing with yourself the entire time we've been in the living room, Mom. Tell me, how many times did you cum?"

"I-I don't know, Master! I stopped counting after you started fucking your sister! But I can tell you that I came four times by the time you took Rachel's virginity! Oh, fuck! Speaking of cum, I'm going to cum right now, Master! I'm cumming! I'm cumming!" I don't slow down at all as I continue to fuck mom at the same pace as she cums. "You are such a massive slut, Mom. I've been fucking you for only a minute, and I've already made you cum. I bet you love being a slut."

"Yes! I love being a slut! It feels so fucking good being a massive slut! I want to be your massive slut, Master! I'm so glad you're my son, Master! You're the best son a slutty mother like me could serve as a sex **** for the rest of my life!" I start to thrusts my cock a bit faster inside mom's pussy. "And I'm glad that I have a very sexy and slutty woman like you as my mom. I'm looking forward to the day you tell me you're pregnant with our first child. I can't wait to see how big your titties will get when you're heavily pregnant." Mom tries to say something but can't as the only thing coming out of her mouth are moans.

I check the clock every now and then to see how long I've been fucking mom. Once I see that I've been fucking mom for a little more than 20 minutes, I decide that now is a good point to end mom's turn. "Get ready to have your tight, slutty pussy filled with my cum again, Mom." Mom just responds with moans. I already know that I've successfully impregnated my mom with my child. I haven't gone on the app to see if a message will pop up telling me I've impregnated my sister. But I'm positive that I did successfully impregnate her as well. I'm not going to go on the app to check as I really want to fuck Rachel again after I finish cumming inside mom. In my mind, I think, "Cum," and I start to cum. Mom lets out the loudest moan since I started fucking her as I fill her womb. Once I finish cumming, I slowly slide my cock out. Mom tries to catch her breath as my cum leaks out of her pussy. Before I can say anything, Rachel grabs my attention by saying, "Yes! You've finished cumming inside mom! Now it's my turn! Please hurry up and start fucking me, Master! I can't wait any longer!"

I look over at Rachel to see she already has her legs and pussy spread for me. I think Rachel was playing with herself while I was fucking mom as her pussy is dripping wet right now. Rachel looks at me with a confused expression on her face when I sit down on the couch. "What? Master, why aren't you coming here and fucking my tight, slutty pussy? You said you would fuck me again after you finished cumming inside mom. Please, Master. Please fuck me. I need your big, hard cock inside me again so badly."

"If you want my cock inside you again so badly, then come over here and start riding me, Rachel." After I say this, Rachel quickly approaches me and stands right in front of me. She stares at my hard cock for a few seconds before climbing on top of me, facing me. My older sister lines her pussy so it's right above the tip of my cock. Before Rachel inserts my cock inside her pussy, she says, "I promise I'll try my best to make your cock feel good, Master." I notice that mom has finally caught her breath as Rachel slowly slides my cock inside her. Mom starts to play with herself once again as Rachel now has half my cock inside her. Once my cock is fully inside my sister's tight, slutty pussy, she says, "I'm going to start bouncing now, Master."

Just like Rachel said she would, she starts to bounce up and down on my cock. She's bouncing at a moderate pace. I wrap my arms around Rachel and grab onto her ass. Rachel starts to moan as I give her big ass a light squeeze. "This big, round ass of yours belongs to me, Rachel. No other man is allowed to touch it besides me. I am the only man who is allowed to fuck you. Do you understand, slut?" I spank Rachel's ass hard before she has a chance to answer me. "Y-Yes, Master! I understand! I don't even want to have sex with another man! The only cock I want is yours, Master!" I stare at Rachel's breasts as she bounces on my cock. I'm going to make Rachel's breasts grow bigger using the app later. But I don't think I'm going to make them grow to be the same size as mom's breasts.

Rachel gradually bounces faster on my cock as time goes on. I check to time to see that Rachel has been riding me for about 15 minutes now. "Am I doing a good job making you feel good, Master?!" I spank Rachel's ass again before I answer. "Yes, Rachel. You're doing a great job." My sister smiles at me after I say this. "Are you getting close to cumming soon, Master?! You're going to cum inside me again, right, Master?!" I'm about to say yes, but an idea pops up in my head. "I am getting close to cumming, Rachel. But you're going to have to ask mom if I can cum inside you. If mom says yes, then I'll cum inside you."

"Please, Mom! Please say yes! I want Master to cum inside my tight, slutty pussy again so badly! It felt so good when Master released his warm cum inside me last time! You said Master came inside you twice! It's only fair that Master cums inside me twice! Please, Mom! I'm begging you!" Mom rubs her pussy faster as she hears Rachel beg. "Please, Master. Please release your cum inside your sister's tight, slutty pussy again." Just as I think in my mind, "Cum," I hear the door to dad's office open.
