I'm helping my friend mark her 18th birthday in the most pleasurable way possible

My best friend just turned 18 and she\'s been begging me to take her to a wild party. I\'m not really into that kind of thing, but I figured I\'d humor her. So, I took her to a place where they serve alcohol to those under 21. She had a blast, and now she\'s ready to celebrate with me in the most hardcore way possible.
