Chapter 15: Doorway to the Future

Downstairs, Dana asked her son, "So what did you want to talk about? You seemed to have a hard time dividing your gaze between me and Ariel up there."

David didn't answer his mother directly. "Whoa, I've been fucking my own Mother for a month. That is so cool!"

"That still doesn't tell me what you wanted to talk about."

David was panting, and his cock was shiny hard and throbbing. "I can't talk now. I need to fuck my Mother."

His stacked mother was puzzled, but she sat down on the couch and spread her legs for her son. "You're acting oddly David, but if it means that I get more hard cock pounded into me, I guess I'm not going to complain."

David fucked his mother almost as if he were in a trance. He sawed his cock back and forth for about three minutes before he launched his jizz into her. Dana came along with her son, but she was worried that he was backsliding when it came to controlling his cock. "Oh, I've been such a fool!" David said mysteriously.

"David, what is going on with you? You're cumming awfully quickly today. It's like your stamina has completely deserted you. And on top of that I have no idea what you're talking about. Why would you be a fool? You're not feeling guilty about having sex with your mother now are you?"

"No, if anything the opposite is true. The first time you seduced me, I didn't really think about you being my mother. I just considered you a super hot chick that I was getting head from and was going to get sex from too. I've always considered fucking you and Ariel as approximately equal in quality, when I should have much preferred you. I can't believe I haven't been appreciating the hot Mommy sex you've been serving up properly."

"Um, thanks, I think. But I'm still not exactly sure where you're going with this. You're saying that you've been unable to control your cock because you're aware of the fact I'm your mother when you weren't before?"

"Isn't it obvious? The scenario we played out was supposed to break down the guilt that Joseph felt when it came to incest. Well, it affected me as well. I thought I'd be able to chase after all kinds of hot chicks and have a good chance of reeling a lot of them in with all you taught me Mom. Now I don't want to though. The only sex I want is incest." David's cock had remained hard after cumming in his mother, and now he started pumping it in and out of her again.

"That's good baby, but remember, Mommy's been very aware that she's been fucking her son all this time, and I've gotten used to lots of pounding before you cum. I want you to relax and try to make Mommy cum multiple times before you drop another load of jizz in my belly." Despite her words about easy relaxed sex, Dana was wantonly bucking her hips to meet her son's invading cock.

"But incest is so good!" David protested. "How am I supposed to hold back?"

"The same way you learned when we first started fucking. Remember how you weren't used to any sort of physical stimulation to your cock, so when you combined that with visual stimulation, you were going off like a rocket?" David nodded, and Dana continued. "So close your eyes and slow down. My pussy isn't going anywhere. I love having your cock inside it, so you can take your time. That's it. Make love to Mommy slowly. Mmm, mmm, yes." Even though Dana got her son to slow down, Dana kept working him hard with her own fucking motions. "You're doing it baby, you're going to make Mommy cum. Don't get excited though. Use that long cock of yours to make Mommy cum without cumming yourself." Dana began to writhe and moan under her son.

"Mom, are you cumming?"

"Yeah, I am. Fight your orgasm; I want you to hold off."

"I don't think I can Mom! It feels so good when you cum! I'm going to have to learn to resist that feeling all over again."

"Fight it! Fight it!" Dana pleaded.

David grunted as he buried his cock into his mother, then his body shuddered, and it was obvious that he had lost the fight with his urge to cum. "Sorry Mom, I tried, but I couldn't hold it. Still, it's hard to feel too bad about it. You had already cum, and I came so hard even though this is the fourth time I've cum in a really short amount of time."

"It's OK," Dana panted. "It's not like I'm not being satisfied by your fucking. It's just that I'd be more satisfied with multiple orgasms. So, what's Ariel going to do now that you've realized that you only want to fuck me?"

"I didn't say I only wanted to fuck you, I said I only wanted incest. The whole reason I came all over your thighs without anyone laying a finger on my cock was that I was pretending that Joseph was fucking my big sister!"

Dana gasped, "So Joseph started thinking of me as his surrogate mother because he was unaware of his need for incest..."

David interrupted his mother, concluding her thought, "And I started thinking of Ariel as the big sister I never had because of the cure we provided Joseph. In fact that leads me to my question." David grunted, and his cock, which had gone soft but was still inside his mother's pussy, started hardening rapidly. "Do you think Ariel would consider, um, getting off ... what the fuck is happening to my cock?"

Dana had seen a similar reaction from Joseph, and it seemed that there were other side effects to Joseph's cure than just David's increased interest in incest. She smiled as she had a good idea of what was about to happen.

"I mean, I know Ariel's BC ... for a long time ... ugh ... for me ... stop taking ... so I can..." David's incoherent thoughts trailed off as his cock suddenly started pumping cum into his mother. "What the fuck! How did I cum so quickly after the last time and why am I cumming so hard? I thought I was going to be worn out after all I'd done. Ugh! Ugh!"

"I think you may have been infected with another one of Joseph's sexual interests since you participated in his cure. You were wondering if I thought Ariel might stop taking her birth control pills so you could knock her up?"

David flexed his rock hard cock inside his mother as she correctly deduced what he was thinking about. "Mom, how did you know that's what I wanted?"

"I told you, Joseph has experienced similar reactions when presented with the idea of knocking either Ariel or I up." David groaned as his mother continued. "I'm not sure what Ariel would say, but I don't think you should be shy about asking her. If your big sister isn't interested in helping you become a father, your mother certainly is!"

The meaning of Dana's words didn't hit David immediately. Once he realized all of the implications of what she had said his eyes got wide as saucers and his cock exploded cum into his mother yet again. "Oh, I want to do it. I want to knock you up Mom! Then I want to knock Ariel up too! You wouldn't mind that would you? After you carry my child, you could let Joseph knock you up while I'm working on Ariel!"

Joseph pumped his cock in and out of Dana slowly, trying to make his hard on last as long as possible. "I don't understand Dana. Why are you telling me you won't be letting me do this for a few months? Don't get me wrong, your blow jobs are awesome, but I need to fuck you too. For the last two weeks, I've been having the best sex of my life with you and mom, and it's been entirely guilt free."

"You only think you've been having the best sex of your life. Starting today, you're going to be having the best sex of your life."

"That doesn't make any sense. If I'm not having sex with you, I guess you're talking about my Mom. But I know she hasn't been holding back on me. She fucks like a wild woman! What could she do to make sex with her even better than it is now?"
