I'm a student who is retaking entrance exams, so I started working part-time at a convenience store and a bar to earn money for cram school. I was told that I would be working two shifts a week, but when I started, I was working five shifts a week...I don't have time to study...I'm in trouble. When I study at my part-time job, my senior at my part-time job, ``Uno-san,'' who goes to the school I want to go to, is concerned about me and offers to tutor me...I'm grateful. However, we are alone in the room...I can't concentrate on studying because of her sweet scent and the glimpse of her cleavage. When she notices that I have an erection, she says, ``You should get it off once. I'll watch you, so you can jerk off.'' What do you mean, public masturbation...I'm embarrassed...But I can't concentrate on studying until my arousal is cured...I took off my pants and ejaculated while Uno-san was watching me. ``Well, from today on, I'll manage your ejaculation! You're not allowed to masturbate without permission!'' It was supposed to help me concentrate on my studies...but I'm frustrated and tormented every day...I can't concentrate on my studies as much as before...What should I do? "Teacher, I can't take it anymore! My mind is going crazy. I've reached my limit..." Then Uno-san said, "Then let's change the ejaculation date! Let's jerk it off now." She took off my pants and gave me a hand job... I thought it was just that, but she gave me a blowjob!? I had no experience with women, so it was my first time receiving a blowjob... I lost my virginity in the break room at my part-time job, surrounded by strange excitement... Now that I know the pleasure of sex, all I can think about is having sex with Uno-san, and I can't concentrate on studying. But those worries were just unfounded. My grandmother, who found out that I was in trouble because I was constantly working part-time jobs, offered to pay for my cram school fees and even hired a tutor other than Uno-san without my permission. I will never be able to see her again... What will become of my relationship with Uno-san?
