It was three months after our 18th birthdays and a week after graduating high school when our two moms turned our lives upside down. Yes, you heard me, Tim and I have two moms.
At the time we were born, four days apart (me first), our moms and their parents were estranged, after their declaration of being a lesbian couple, and Mama Sarah and Mama Marie made the strange decision to not reveal whose son was whose when they announced that we had been born, in the hope that both pairs of grandparents would treat us equally. They gave us both the hyphenated last name Wolff-Carter, although they hadn't been able to marry yet. The existence of grandchildren did mostly end the estrangement and we were accepted as grandsons by both families.
This secret continued as Tim and I grew old enough to realize that we had each been born to a different mother instead of being twin brothers. So, we took for granted that we had two moms and when people asked, "Which one is your real mom?" we could only answer, "They won't tell us."
When we were 15, they sat us down for a family meeting and finally showed us our birth certificates and the adoption papers that gave them joint custody. These revealed that Tim was Mama Sarah's son and I was Mama Marie's. Neither listed a father's name. When they legally married a month later, I walked Marie down the aisle while Tim did the same for Sarah.
We had grown up loving both of our Mamas and Tim and I reassured them that knowing the truth didn't make a difference to how we loved them.
We never expected that to be tested.
When they called another family meeting like the one when we were 15 on that Friday night in late June, we had no idea what it was about.
Once we were seated, Mama Sarah began, "Hear us out on this, please. What we are about to ask from you will sound really strange, but here goes. Mama Marie and I want more children, since you two are headed to college soon. We decided several years ago that our preference would be for the two of you to father them, but we needed to wait until you were 18 to ask."
"What did you say?" I sputtered, looking over at Tim, who looked as stunned as I felt.
"You heard me, Aaron. You would impregnate me and Tim would do the same for Mama Marie. That way, Marie's baby will be my grandchild and vice versa. Before you say it, 39 is not too old. Also, we should both be ovulating in a couple days."
Mama Marie took over. "You would sign contracts like you were donating sperm and your names would be left off of the birth certificates. We would expect you to keep this a secret, let us raise them and just be their big brothers."
Tim asked, "Couldn't we actually do artificial insemination, like you did to have the two of us?"
Marie said, "While step-parents having sex with adult stepchildren is not a crime, we doubt any fertility clinic would agree to using your sperm."
Sarah continued, "Besides, you can't tell us you've never fantasized about us. We've both noticed you looking at us more and more differently since you learned who your birth moms are and aren't. Especially when you've been without girlfriends and horny, like you are now. Looks you would have avoided giving us you now let linger, while you still turn away from watching your birth mom the same way."
Marie said, "We've seen your Internet histories, too. You both watch plenty of both MILF and incest porn, especially the step-mom/step-son stuff, but some that pretend to be real moms with real sons, too. We also saw searches with 'mom swap' and 'son swap' as keywords, although there don't seem to be that many videos like that, certainly not whole series like there are for daughter swaps, where two dads have sex with each other's daughter. But it shows you're at least turned on by the concept of incest."
"Um... I use incognito mode. How could you know what I watch?" Tim asked, signaling that he wasn't denying it.
I couldn't deny it, either. The incest pornos were the videos that turned me on most. I was watching almost nothing else since Cara had broken up with me right after prom. It felt like a fixation. One I tried (and failed) to deny had anything to do with Mama Sarah directly.
Marie answered, "That mode suppresses the browser's history, it doesn't affect the site logging we left set up on the firewall. We've learned a lot about your viewing preferences. Aaron's watching a lot of blonds like Sarah and your preference is for brunettes like me, Tim. Tell us if we're wrong about that."
Silence from us as we looked from face to face.
Sarah said, "So, we're asking for a son swap, until we get pregnant, if not all summer. We'll give you a day to think about it and talk to each other. If you're not both a yes, we'll go with anonymous donors instead, but we want to both be pregnant before you leave for college, either way."

Tim and I retreated to his bedroom to discuss the bombshell whose fuse had just been lit.
"Can you frigging believe this?" he asked, flopping on his bed, while I sat at his desk chair.
I shook my head no. "I feel like I'm dreaming, to be honest. Not like a nightmare, but it does seem way too good to be real."
"You're leaning towards saying yes, I take it?"
I said, "If it truly stays between the four of us, I can't actually think of a reason to say no. What the rest of the world would think won't matter, because they won't know. I would do anything to make either of our moms happy. Even this. Besides, how many times have our friends called both of them MILFs to our faces and pointed out that one is our mom and the other is just our step-mom? They've practically egged us on to make a move."
Tim nodded. "Instead, our moms made the move first. And have been thinking about it for years, apparently, waiting until we were old enough. I'm... I'm in if you are."
"Yeah. Just in separate rooms, okay? Not like those videos where the dads swap their daughters side by side."
"Afraid to see me in action?" he asked, grinning.
"Not you, Mama Marie. It's enough that I fulfill my fantasies about your mom, I shouldn't be adding fantasies about my own."
"Good point."
