Follow them

I manage to follow them without drawing attention to my as the talk. "Amy, what the hell is going on with you? First in class you strip down to your bra and pants and now you cough up....cum and scream that your not a slut right before you orgasm?" Josh asked with a concerned tone. "I...I don't know what's going on. None of this makes any sense..." Amy tries to apologize.

I smile as it looks like their relationship is about to cave in. Should I keep messing with her or wait and finally fuck her once they're alone together?
