It was our presentation day at my university. We were divided in groups of five people each, one group was giving their presentation, and one of the students was doing the major talking. The other people, all girls, were just staring at their project, the speaker, and the faculty. I was scanning through all the members of the group, and suddenly I noticed one girl's neck quickly and strongly suck in (three hollows). It was very sexy, and I started to feel hot. I waited, and after about 6 seconds, I noticed her shoulders jerk up. Then 6 seconds later she did it again. She was a bit dark, dark brown hair tied in a pony tail, nice face, quiet attractive, she was wearing light color clothes. She was also wearing glasses (specs probably). She kept hiccuping at different time intervals, 4, 5, and six seconds, sometimes she would hiccup after 4 seconds. I think a couple a times she did a cluster of 2's. All that time she was silently hiccupping. She noticed me looking at her (what else is new!) and felt a bit embarrassed, and hid behind one of the girls. She would sneak out for a few seconds at intervals. So I stopped staring at her, but at different times, I WOULD look at her, I couldn't help it. Poor girl. She kept having them. Then I thought I must leave the classroom, as my prentation had been done, and also because she knew I was watching her, and also because I was geting so hot, and couldnt stop the "happenings" in my private parts. So it was kinda foolish of me to stay there and stare at her like a donkey. Because females know when a guy's getting excited. I was starting to sweat! So I left the room. Outside I saw her after 15 minutes-WITHOUT the hiccups. She passed in front of me twice, I thought she did it deliberately, but who knows! WOMEN!
