Eh. For the 2nd half of it... though Tsubasa (black haired girl) is kind of pretty and has a mysteriously dark backstory of sorts, I can't say I like her. The sex felt jarring because of how mean the black haired girl is and also... the location...
Besides the feelings of disatisfaction that will probably be addressed in the next chapter...
Girl, don't chomp lollipops like that. That's probably painful.
