I just want someone to write something where the DB is married and has (possibly) adopted one or two kids. The spouse loves them but he/she finds that they also want a child of their own flesh and blood so to speak. Cue them then approaching the DB with this request and the DB getting nervous because they either aren't ready to totally settle down yet. Or maybe they are just super unprepared for pregnancy/not so good with very little kids. (I mean, all the kids you can adopt seem to be at least seven or eight and thus capable of taking care of themselves to an extent.)

Any race for both DB and the spouse are welcomed.

I feel like a male/female dynamic would work best for this for obvious reasons. But, if you want to indulge my not-so-secret now love affair with M-preg be my guest. Hell, i'd even be ok with two females. (and then they must consult a wizard about ways to magically preserve/insert the sperm?) The last two options might be stretching lore a bit but meh. I like challenging canon from time to time.

Bonus points if F!DB is the one who gets knocked up and is a downright hormonal emotional mess. (Or Alternatively, M!DB being ridiculously worried about their wife's pregnancy.)

Double bonus for the adopted kids (if there are any) being excited about this addition to the family.

Triple bonus points for fluffy "Let's make a baby" sex.

Quad? Bonus points if a lot of the DB's companions know about it and come visit and then the whole thing becomes a town topic to speculate on. (Maybe they even draw bets about the babies gender?)
