busted a kindergarten
When you're doing someone from behind and you pull out and redo their back with enough droplets of semen to be compared to a kindergarten of students. In total the semen should equate to about half a gallon.
So I was banging this girl from behind doing her right and I felt a perfect storm of semen busting through my crotch, and in spur of the moment I busted a kindergarten on her back and weighed her down so much I had to scrape it off with a shovel to free her. RIGHTEOUS!
