[MUGF-012] I'm worried about what kind of stains and dirt are on the pants that school girls wear all day, and I get very horny. (Censored)

<p>Only obscene delusions float in the underwear worn by school girls. I wonder how much the pants that are in close contact with the genitals all day have been soiled. I get an erection just by thinking about what kind of stain I put on it and what kind of taste and smell it smells like. Ah, I want to see... I want to lick it... I want to smell it... I want to fill... I want to fully enjoy the dirt on my pants...</p>
