My senior's girlfriend, Asuka, is a gal but kind, and I secretly thought about her, even though I felt bad for her. One day, my senior decided to go on an expedition, and Asuka started to flirt with him! I felt bad for my senior, but I couldn't help it! It's your fault for leaving such a good girl alone - a record of the two of them repeatedly having endless creampies for three days while her boyfriend was away.
