I finally got a girlfriend... But, as a virgin who has no experience with women, I don't even know what would make a girl happy... In times like these, the only person I can consult is my mother-in-law. Then she made a shocking proposal, "Will you lose your virginity with me?" Even though we have no blood relation, with my mother-in-law... For her sake, I even overcame premature ejaculation and practiced making her cum. But, as I repeated sex practice, I realized... Mother-in-law, me... I can't get excited (erect) unless it's with my mother-in-law!
