FASH: This is just for you Jack, because I know that amazing, unprecedented crack makes your day. Here's a short continuation, based on the fact that after the the end of the first chapter, I really wanted to type out 'little did they know...'
Sena gave Akaba a rather sullen look and crossed his arms as he sat beside the red-head on the love-seat in Akaba's apartment.
"You said men couldn't get pregnant."
"I'm well aware of that, what I didn't know was that you were somehow blessed by the M-PREG Fairy and were given the ability to give birth." Akaba gently rubbed Sena's hardly noticeable protruding tummy. "Besides, I think you'll make a very good mother."
Sena glared at him half-heartedly before turning his attention over to Yamato, who'd been pacing around frantically for the last couple of minutes.
"Yamato-kun, what are you doing?"
"Names! We need to think up names! What if it's a boy? What if it's a girl? Do you think that, due to their amazing breeding, they'll become the best football player ever?!" Yamato finished excitedly, leaning forward to cup Sena's face in his hands.
"And remember Sena, call me Takeru, there is no need to be so formal." He grinned widely before crushing Sena in a hug. "Oh! I'm going to be a daddy!"
"T-Takeru... Can't... Breathe...."
"Oh my goodness! So sorry!" Yamato quickly let the smaller boy go and carefully sat him back down on the love-seat before resuming his frenzied pacing.
"Fuu. Right now we shouldn't be worrying about names anyways. The most important thing is telling everyone that Sena has defied the laws of nature and is with child."
Yamato stopped his pacing for a moment. "How are we supposed to get them to believe us, I mean, it's not like this happens every day. It's a modern-day miracle." He gasped dramatically. "Once word gets out about this, dozens of mad scientists are going to try and kidnap you! Don't worry, I'll protect you Sena!"
Sena sighed and rubbed at his temples wearily. "This is going to be the most awkward situation I've ever had to go through. My parents are not going to like this. Mamori-neesan is not going to like this. Hiruma-san is probably going to try and castrate the both of you."
Akaba shifted uncomfortably and Yamato paled a little, both of them knowing that it was probably true.
"On the bright side, now all those other guys will believe me when I tell them I'm already in a relationship and they'll stop bugging me." Sena mumbled to himself, causing both Akaba and Yamato to tense up.
"... What other guys?"
"It doesn't matter, I'm sure they won't bother me anymore."
"But just to be sure, I think we all need to get married!" Yamato said with a wide smile.
"Fuu. All of us? That's not exactly legal."
"We'll get Hiruma to make it legal then! And then no one can take Sena away from us!" Yamato threw his arms around Sena once more.
"True enough." Akaba responded. "Shall we start picking out the rings then? And sending the invitations?"
Sena sighed, but snuggled a little further into Yamato's embrace. "I should have known I wouldn't get a normal proposal out of you guys."
