something men do in their free time
I was bored in math class when I suddenly got this huge boner. I ran to the bathroom and there were like ten other guys in there jacking off. One of them ran up to me shoved me down and ripped off my pants and boxers and started shoving his puny dick up my ass. I turned him over and shove my 9 in cock in him and he started moaning in pain and joy. I went faster and faster until i unloaded a gallon of semen in him.
