When a timid otaku is in trouble with an erection, "a gal pulls it out even though it's not her sexual processing duty!"

In 20XX, sexual processing duty became a daily routine. At school, it is normal for boys to take turns "taking care of me".

Meanwhile, Otaku-kun, who is afraid of senior boys, did not have the courage to mix with other boys and have them sexually processed.

One day, I took the plunge and asked the gal next to me, "Would you like to suck me?" When I asked... Even though I'm not on duty for sexual processing, I'm going to pull it out! Since then, Otaku-kun's daily life has changed completely. Every day, a miraculous "sex activity" where you can be by a gal has begun.

However, in the midst of such days, the "Gal Sex Processing Duty Day" suddenly came...
*There is no NTR development.

This is an erotic manga about girls on "sexual relief duty," a job at school where they relieve the sexual needs of boys. Sexual relief duty stories usually have a plot where the girl on sexual relief duty makes various boys ejaculate. However, the concept of this work is that a gal who is not on sexual relief duty relieves the protagonist's sexual needs. "Making you cum even though you're not on sexual relief duty" means "you're being treated specially." In other words, this work can be said to be "an otaku-friendly gal story disguised as a sexual relief duty story."
