Time isn't going to change anything, they aren't futa.
Both of them are male.
They are born male.
But they can transitioning. With hormonal treatment and minor surgeries.
But without going up to a complete reassignment surgery. Keeping their penis and testicles, while having boobs and a feminine face and overall body.
So they will look like futanari, minus the height and more muscular body.
But
Kind Nightmares state here that not all the futanaris look like Jade with an amazon body. Some have more delicate figure.
The remaining question is: is there a chance that Sam and/or Andy will become pre-op transwomen.
It seems to me it won't be the case for Andy. Like others write, I think it will just become a Sissy.
But I think Sam could. If Jade is right and deep down he feel he is a girl, he could start a transition.
If so, I hope we will have an option to keep him as a pre-op transwoman.
