Actually megaboobs doesn't happen when being captured by her. You have to give Linda a meat tendril or get them to take away your parasites. It's a lengthy process but go back the next day and help them rescue the scientists. I don't want to spoil bc idk if you actually did this already.
But it happens when searching for 'something' in the underground base after the quests connected to the science lab tower and you have to let yourself be defeated by enemies
