Replying to Help getting out of trouble with a party i had

Hey, i had 2 small partys at my house this week because my parents left monday-thursday. The first on tuesday there were 10 or 12 of us just drinking, then the next day there were like 15 kids. The first day somebody slept in my sisters bed and my parents found that out because the bed sheet was on sideways (how gay is that?). Then they found a single beer in my backyard and know i was drinking basically. my parents know at least 1 kid was here each night, my question is how the fuck do i get myself in the least trouble i can?

here's what they know i did wrong:
-i had 1 kid over tuesday, and 1 wednesday w/o my parents permission
-the beer that they found
-neither of my friends parents knew that my parents were out, one of my friends parents found out and isnt too mad but they called my parents


Here is one idea i have for a story to tell them. well one of the kids was from the town over, and i know him from sports so i could say that a few kids that i dont know came over to go swimming and i was getting my shit dried off when we were done and told them to just leave when they are ready, and then they started drinking out back and left a beer. How does that sound?

what other storys could i tell them?
