I was in the guys toilets taking a piss at the urinal, there was another white dude student standing beside me at the other urinal. I heard some giggling and turned around to see four Japanese girls standing behind me. I noticed a couple of them from my class. I was shocked as to why they were in the guys toilets. Two of them were inspecting the dick of the guy standing next to me, which was flacid. One of them was standing around watching guard.

The other one came up to me asking "May I ???" i noticed her from my class her name was Ryoko.
I mumbled "Ok" Ryoko started putting her tiny finger on my dick.
"Hey Mico" she called out to her friend who had been inspecting the other guys cock. "Come over here and have a look at this one" she told her friend.
Mico came over to inspect my cock.
"There not very big, but this one is much fatter" she said comparing are flacid cocks.

After that I headed back to my room (I have my own room on campus), When I closed the door i was shocked to see that Mico and Ryoko had been hiding behind the door. Mico is about 5'5 with light brown hair tied back in a bun and Ryoko is about 5'3 with long black hair. They both put there arms around me.
"We want to see how big it can get" Mico said while Ryoko started pulling down my pants.
