A kind older sister visits and provides support to a man who has been living in isolation in a hoarder's house for about 30 years after failing his university entrance exams. She notices a mountain of used condoms in the house and, unable to bear it, decides to offer him sexual support, even for his filthy, semen-covered cock, with her overwhelming maternal instincts. Since the man is a virgin, he starts demanding more and more sexual support, getting bolder with each request.
