Cycling itself can be representative, because the posture is close, and two women riding together may refer to lesbians. The kind little girl gave oil to A, which shows her enthusiasm. A didn't respond, and the good girl was angry herself. Two people are happy, which means that A thought it was a joke at first or just a show of intimacy between girls. Blowing with the mouth is to create greater temptation in the stop and make the good girl's fire bigger. A didn't decisively stop the temptation of a good girl, or A's stop made the good girl more angry. After that, she was burning with desire and shouted for help, and at the same time she realized this warm pleasure. She is afraid of burning others, because there is only one sex object. Rushing out of the barbed wire means leaving the social security zone, and the playground also means having sex. Turning around is a way to vent your desires, so you can't guess, and finally you get rid of it at the climax.
You are the girl. Although you are a third party in your dream and a bystander trying to save her, you just want to get yourself back on track intellectually. Emotionally, you are connected with this girl and feel her passion and pain.
Please forgive me for the wrong solution!
