Your futa mom has always been chasing off your potential girlfriends and today is the day she finally explains her reasoning for it. Futanari are conquering the world and subjectating males and becoming the dominant species. Wearing a tight one piece swimsuit with a clear obvious buldge showing through, you accompany your futa mom to the beach. "Isn't it a lovely day at the beach, son? Bright, clear skies, beautiful weather, I can work on my tan and you... what are you pouting about? Ugh, again about the girlfriends? Look, I know you get angry every time I make you suck my cock or fuck you in front of them, but it's not that weird. The job of every good futa mom is to get her son ready for the real world. I mean look around you, there's so many more women at the beach with giant cocks like mine than there are men or women. These girls you're bringing home might... think they're happy with you. But truth be told they're not gonna wanna stay with you. They're not gonna want some lowly male getting them pregnant. Futa women are stronger, smarter, and better looking than you. I'm just geting you ready for that. You're more than welcome to stay here and nurse on mommy's cock forever, but don't you want your own life? Don't you want a beautiful woman with a big cock to bind you and call you her own? Let's just... forget all of that and come splash around in the water with your mom." At which point you beckon me to come join you in the ocean. "Now see, isn't this nice? Let's just forgot about all that other stuff and enjoy a nice dip underwater. Hey, wanna see who can hold their breath the longest?" At which point you pantomime like you're gonna go underwater and pull back, at which point you pull out the huge cock. "Wow, only 20 seconds? I'm really disappointed in you, honey... Why is my cock out? OK, so I did fib a little bit, but honestly I'm just not too happy with your ability to hold a cock in your mouth for an extended duration of time. I know you out-paced some of your girlfriends but what are you gonna do when an extra horny futa fucks your mouth for minutes on end? We need to increase that lung capacity, and what better way than giving me an underwater blowjob! You're gonna take this massive cock all the way down to the balls while I hold your head underwater and count. Down you go!"At which point you hold me underwater for 30 seconds, all the while talking about how good it feels, to stop struggling because you're too strong and can hold me down, and maybe occasionally counting numbers until you reach 30, at which point you pull me back up by the hair. "See, I knew you could do more than 20 seconds. You just needed encouragement from your dear mommy. Back down you go, this time let's do a minute!"Same thing, except maybe fuck with me and count backwards a few times especially towards the end. Talk about how struggling will only make it worse and you'll lose more oxygen that way. Then you pull me up again."Wow, I can't believe how hard I am. You're gonna make some lucky futa the happiest woman on Earth, but you can't leave a job unfinished. I need to cum, baby, and now there's no clock. You go until you swallow my load."You push me back down, and this time you talk about how you've locked your legs around my head and there's no moving off your cock. It's do or die, literally. "I didn't raise a quitter, but I'll be honest if I did maybe this is for the best. I'm watching you struggle and seeing less air bubbles popping up. Honey.... honey? Oh there you go again. Oh, I know how weak and helpless you feel right now, and mommy does feel bad about this, but there's futa out there that are gonna wanna do much worse to you and you need to be prepared. It's survival of the fittest and well... men aren't that anymore..Would it help that I told you I loved you? Oh a second wind! Oh my god, baby, where did this come from? Yes, yes, mommy loves you so much, dear, you're gonna make mommy shoot the biggest load. Here it comes baby!"After cumming, you pull me out of the water "My, my, that was right against the wire, wasn't it? Mommy does love you, honey, and you've always done everything mommy asked even when it seemed cruel and mean, including this. But trust me, I'm doing it all for you. You're gonna be the best little cock sucker you can be."
