A girl in uniform who works hard at a convenience store for her boyfriend has sold her body for a slight increase in hourly wage... Kasumi, who has no money and is working part-time in the middle of the night when she really shouldn't be working. The proposal from the store manager, who took advantage of that weakness, was a part-time job behind the prostitution business. The store manager who was aiming for the J cup asked for sexual processing here and there. The bite of the sexual intercourse that starts from sex becomes thorough to SEX and vaginal cum shot, and Kasumi's mind and body are worn away day by day.
