The way I see it there are a few different endings (warning autism)
First path is that Dexter fuck her, and she in a crescendo of milk and sweat, explodes. Popping end for those who are interested in that stuff (snuff?).
Second path that Dexter gives in and fucks her.
Two paths are available to Dexter's Mom: return to her original size, stay the same size, or get bigger.
Dexter's mom can let Dexter at his behest, shrink her back to normal. Afterwards, she becomes his secret fucktoy. Dexter drops out of school and plows her all day long, expanding her to huge sizes whenever he desires. Mealtime, coming back from the groceries, while she's saying "No" to Dad for sex... his mom is now a forever butt-slut who loves only Dexter.
If she chooses to stay the same, however, Dexter will very reluctantly oblige. He will help Mom ease out and disappear from her former life. She then spends her days in perpetual orgasm as her Son's personal milk factory, supplying lubricant for whole lab. She becomes a milk factory who loves only her body.
But if she demands to get bigger, Dexter will be horrified and refuse, and attempt to revert the changes and wipe her memory of the past day occurring. Failing to stop him, would lead to the worst end where Dexter's mom remembers nothing.
Stopping him means that Dexter's Mom manages to roll on top of him, smashing the raygun into her tits. From there, she resumes swelling but this time without limit. Dexter's voice gets quieter and strained as the space arounds them shrinks, as her body presses up against the walls of the lab. As the walls break down around her, Dexter's Mom becomes a goddess in love with her own neverending growth.
