What are my options if I’d want to be smaller up top for work, exercise and every day life, and absolutely massive for private time and date nights?

I'm going to level with you. To say that your options are "limited" would be putting it lightly. The way I see it, you basically have two ways you could do something like that and neither of them are ideal.
The first—and more effective—of the two options is that you could find a friend to act as your Safety Deposit Boobs. When you need to be smaller up top, you just transfer your colossal udders to her and then transfer them back when it's time for some fun. The complicated part isn't the magic to do the transfer; as long as you can get your hands on the ingredients, the magic itself is pretty easy. Your friend, your designated titty bank, might have something to say about it, though. She'll likely have "work, exercise, and everyday life" things to do, too, and she'll need to do most of them at the same time you do. You'll need to find someone who wants to have a pair of gigantic, bouncing udders in the office or on the treadmill and then wants to be nearly flat chested for dates and whatever else. Otherwise, if she needs them at the same time you do, you might wind up with a mu-titty mutiny! It'll be hard to explain to the person you're seeing when you show up for the third date and the gigantic boobs they're anticipating aren't there.
The other option would be to keep your huge tits all the time and just try your best to keep them contained. Layer up as many sports bras as you can, wear thick and heavy outfits, switch to a workout routine with less cardio. But we both know that's only going to do so much. For as big as you want to be, they'll still be huge no matter how much you try to squish them down and, while they might not bounce up and smack you in the face, they're still going to jiggle and slosh in their tight confines. Plus, there's the whole thing with needing to breathe, which gets harder with all that tit strapped so tightly to your chest. The relief you'll feel when you can finally let your boobs breathe will be immense, but it probably won't be worth the discomfort and those deep, red lines left by your tight clothes.
There is a third way, though. Personally, it's what I'd recommend. The best way to handle it, in my opinion, is to simply reject the first half of the equation and embrace being busty 'round the clock. Don't be afraid to be the center of attention! When you're doing the butterfly press at the gym and everyone is gawking at your humongous udders being squished between your arms, take it as a compliment! They either want to be you or want to be with you and neither of those are bad things! Sure, you might be a bit of a distraction at the office with those big things wobbling around, but it'd be foolish not to put your biggest assets to use, right? And if you can embrace them during the day, then, at night, when you're settling in for your date wearing a dress cut so deep that every soft, tantalizing inch of your cleavage is on display, you'll feel so much more comfortable and confident and at home in your curves. Go as big as you can handle and then let your life adjust around them. You'll be much better off for it.
And, if you embrace your tits instead of trying to hide them or get rid of them half the time, you'll feel so much better about your desire to get even bigger!
