Nozomi was wondering what sort of guy lured her into bed. Thinking about how this "guy" had made her feel so good, she gets worked up and starts masturbating.
She remembers it was her close friend, whom she has presumably known for a long time and is female. She suddenly changes her attitude and feels like she was attacked.
Its interesting to note that lunch carried on as usual for them and only after acknowledging that things felt so normal did Nozomi have her outburst. Perhaps she feels betrayed, or is grieving the profound change that is about to happen in a close friendship. Maybe she's having a gay panic, maybe it's all 3 at once.
We shouldn't expect ultra realism and backbreaking respect for consent from this manga. If we are lucky, it will at least acknowledge some aspects that I've brought up while the 2 work through the dubious nature of their hookup.
