Don't drink and draw...please

Friday night and this young stud is getting some things taken care of. I'm going to get this drawing that has been plaguing me done tonight if it kills me! I'm not sure why I've never been able to finish it or why I have not had a desire to. Initially it was supposed to be a pencil sketch, but tonight I got the inspiration to finish it in ink. I blame the cold beer and the fact that it is Friday...
