Okay so I know you were think of having tony have a third child in the regency au but from these last few stories where the kids are older maybe you decided against it! But I was thinking-you totally don't have to do this-maybe have tony go into heat and maybe forget to take their birth control because of the stress of planning Peters wedding. Then Opps look who's having another baby! I think it should be a girl but that's totally up to you if you choose to use this! But you don't have to!!
(I was mostly just avoiding it because I couldn’t figure out how to include her lol)
But I like it! Poor Tony, just wanting his baby to have a nice wedding, scrambling to add in the things Matt wants because he has things he’d like included and people he wants to invite. He wants it to be just as beautiful and wonderful as his wedding. He’d had such a good time. He wants Peter to have a good time. And it doesn’t help that his heat falls right in the middle of planning. “You’ll take care of it?” Tony asks as Steve and Bucky try to usher him into their room. “You’ve got my list of things? Oh! And you need to talk to Foggy about–” “Honey, I’ve got it,” Sarah says, amused. “I planned your wedding.” “No roses!” Tony calls out before the door closes. “Matt’s sensitive to scents!” “Honey,” Steve says, amused, then draws him into a kiss. He breaks it to laugh when Tony keeps chattering against his lips. Luckily Bucky sidles up behind him and rolls his hips against Tony’s ass, cock pressing between his cheeks, and Tony goes limp in Steve’s arms with a moan.
And then a few months later, at the wedding, Tony drags Sarah into a corner and whispers, “Sarah, oh my God, Sarah, I didn’t take the contraceptives, SARAH. The baby’s going to be so much younger than its siblings. STOP LAUGHING.” Sarah does, but only because she knows they’ll be missed at the reception if they don’t get back to it soon. “Oh, darling, does that matter? Aren’t you happy?” “Yes,” Tony answers immediately. “But when can I tell everyone? I don’t want to take away from Peter’s happy occasion. But I want Peter to hear it in person and they’re leaving tomorrow for Stark Castle! Sarah what do I do?!” “Oh, honey, don’t worry. We’ll figure it out.”
So Tony pulls Peter aside before breakfast, so, so nervous. Peter stares up at him guilelessly and oh no he’s ruining everything. “I just–wanted you to know that–I wanted to tell you in person–from me–” “Mama, just tell me,” Peter says, and Tony immediately blurts out, “I’m pregnant!” Peter stares at him silently for several seconds before letting out a scream. Tony rears back in terror.
(“MAMA GOT ME THE BEST WEDDING PRESENT!” Peter shrieks, bursting into the dining room. “THE BEST!” Tony hustles after him. “Honey! Calm down!” But Peter is vibrating, he’s so excited, and everyone looks to Tony curiously, unable to imagine what he could have possibly given Peter for a wedding gift that he’s so pumped about. “What did you get them, honey?” Bucky asks, because they’d all agreed on gifting Peter with a beautiful cream-colored stallion to go with all the other horses they would be sending to fill Stark Castle’s stables. Tony blushes and looks down at his feet, murmuring a shy, “Well…” and puts his hand on his stomach. Steve and Bucky begin yelling, as does everyone else. They’re all excited. This is the best news ever. They’re going to love the new baby.
“Okay but what’s going on,” Matt asks once everyone’s calmed down, because everyone had been yelling and he hadn’t been able to hear what they were yelling about, and all he’d heard Tony say is ‘well.’ “MAMA’S HAVING A BABYYYYY!” Peter shouts excitedly. Matt does not flinch at the volume. He wants to though. “Congratulations.”)
