I transferred to a school that was an all-girls school until last year, so of course the school trip was all girls! To be honest, I felt uncomfortable... And the bath was mixed? I tried to distance myself and hide my lower body, but the girls kept getting closer! They even took off my towel and tried to look at my dick! Wait! Stop it! My plea was in vain, and they took my towel away. And my erect dick was completely exposed. Then the girls' expressions changed! It seems that I have a big dick... And the girls started looking at me with sexual eyes! This is a super development that I could never have predicted, and more and more erotic things are happening! In the bath, in the room... they just ask me to insert my big dick. To be honest, I'm exhausted.
