GRMO-082 Human Observation: A plain but cute girl asks for my first ever cock and loses her virginity in sex

A man and a woman who seem to be seniors and juniors at a part-time job. The serious-looking man is asked to take her virginity, and although he is surprised, he cannot resist his ulterior motives and responds to her request, beginning to gently caress her. He is excited by the virgin's overly sensitive reaction, and his seriousness is blown away, revealing his increasingly perverted nature as he exposes his erect penis in front of her face. He is taught step by step, and the virgin is completely captivated by the cock.
