It starts quite mildly, only a little more sexual tension your putting in the air, but by the end of the first trimester it's kicked up into a low fever of sexual agitation, full swing, only getting higher and hotter through the second trimester, until you are almost debilitatingly horny in the third, reaching it's true crescendo whenever your mother went into labor, and when you become all but incapable of anything but fucking and your dick gets a full inch longer because you're just that hard. Making it a very good thing your immune to gangrene.
Of course she'll care intensively for you through it all, "sorry" this ever happened to you "searching for a cure" all year round, and of course gladly offering herself to dick down literally into next year.
Though as you might imagine, she isn't really going to do much of anything about it more than find some way to temporarily pause it, as if a woman like her would sacrifice the months out of the year when her boy-toy becomes a sex god, no matter how annoying a Week+ long erection might be for you as the one wielding it.

>I wish for a similar cougar-and-bait dynamic, possibly with a lesbian or futanari angle, but with with some sexual and or humiliating way to maintain the age difference, like huffing her armpits
