Input: Text: so we have these long benches at school and at my school we stay in one class all day and the teachers come to us every period. 
so these benches block the pathways to the back of the class cus they're so long and we often have to climb over them.
one of my classmates jumped onto the seat of one chair, skipped onto its backrest, and leaped gracefully to the other side. me, spotting a few of my friends (and my best friend's girlfriend) decided to it, since it looked so easy.
as i jumped onto the chair, i lost my balance and the chair tipped forward, sending me straight through the air, eventually landing straight on the valley formed by those two large breasts my best friend's girlfriend possessed, and falling on the classroom floor with her under me.

 
silver lining: her boobs broke my fall.
