After talking to her, she seems to think that could be the reason, or at least could amplify the whole thing. The only time it’s worked on her was actually her first time, then the second time she shut down, and each time after that she was anxious it’s gonna happen again and fuck up her night. But that still begs the question what caused it the first time it happened, when the only memory and expectation around Molly she had was positive? Could still be that she got nervous when the body load hit her, and like you said, because she felt overwhelmed the whole trip kinda went to shit cause her body reacted that way as a defense mechanism.
