I acknowledge my preference and penchant for huge, unweildy boobs isn't for everyone.
Same, would love to see these effects stay myself, especially if they explore the awkward consequences of it - having to buy new wardrobes, awkward questions from coworkers (especially for the professors), and especially if the sensitivity/breast massage effect stays. The loss of control over their own body in a mind control situation is obviously a big part of the heat for me and some other people in this thread, but given that it's not actually Adrian doing the controlling, it'd be quite hot if while the situation was reversible some or all of the gals decided to keep the changes because Adrian expressed appreciation for their new bodies.
It'd also be quite hot if it wasn't reversible and they were all stuck that way, too, though I hope Adrian enjoys it either way, once he gets over the shock of it happening so suddenly.
There's also the art team adjusting, I've noticed that the depictions of the girls' breast sizes have been a bit less uniform for a given character based on them getting familiar with the girls' new proportions. So whatever works for them, I guess.
I get that some people aren't into large breasts, for me the physical change, in the context of fiction, being indicative of a change in their psyche/libido is part of where the heat is, even if it's involuntary. The gals having their bodies changed to be much more... unabashedly sexual, complete with hypersensitive breasts that put them into a submissive trance when stimulated, sounds like a great way for a kink comic to go but I think that for some people that's not "normal" enough, and that's their preference, which is fine, but I definitely have my opinion on the topic lol.
