I entered a school that was an all-girls school until last year, and I was the only guy there! So I was the only guy on the school trip! I thought it was too awkward... But then a group of girls invited me to their room and teased me! Then the teacher came round and I hid under the covers! There was an erotic situation where I was super close to the girls! The other girls noticed and got horny, and it turned into a harem orgy! I let loose and came inside her many times, and it was the most erotic memory I've ever had! Now I'm only worried about getting pregnant.
