So i had this preparty where i invited a lot of people to my house to start off the night before the real party. The night goes well until we start playing beer pong when one of my girl friends decides to crush some crackers and pouring it into my underwear from behind so i dont notice it. 

Later that night two girls that didn't have anywhere else to sleep i guess went with me since i lived five minutes away from where the party was held. Long story short we started tumbling with eachother until one of them takes off my boxer shorts, and voilà... Tons of brown lumps is stuck to my ass and boxer shorts, they proceed to fucking scream and wake the whole house while intoxicated me lays down not knowing what to do with myself. I don't know if they told anybody but i can't wait for school tomorrow.
