So here is a little story I wrote. Would anyone who is good and writing help me out and write it correctly?

This is a story about a guy named Dave. Dave is addicted to crystal meth. One day while Dave is out in the early hours of the morning wandering around town he comes across a man who is having a bit of car trouble. Dave knowing a little something about tinkering with cars and being full of helpful energy offers his help. In no time the man's car starts up and is running. “Well DaveI've been out here all day and you are the only person to stop and help me, but guess what I'm a fucking Genie and you just got yourself three wishes!” says the man. “yeah right if you're a Genie I wish for a big bag of dope.” and poof there was. Dave was shocked but quickly picked up the bag and jumped in the car “Shit man you are a fucking Genie! quick we got to take this shit to my house!” so the genie gets in the car and they drove back to Dave's house. As soon as they get in the door Dave chops it up on the table and sniffs some lines then turns to Genie. “I left you a line on the table,” said Dave and hands the Genie a straw. not wanting to be rude but you need takes the straw and Sniffs the whole line. Throughout the whole night, Dave and the genie went back and forth line after line until the whole bag was done. “Alright Dave it's time for your second wish,” said the genie. “I know exactly what I wish for; another big ass bag of dope,” proof there was. this time Dave went to his drawer and got a pipe and packed a bowl. after he lights up and blows out of cloud he passes it to the genie. Not wanting to be rude he takes the pipe and smokes with Dave. They smoked and smoked and smoked until the next day when the bag was done and the genie said “ Alright Dave it's time for your third and final wish you might want to think about this one” Dave laughed “ Genie you know what I want I wish for another big ass bag of dope!” proof the bag appeared. Dave went to his drawer and pulled out a syringe loaded it and slammed a shot. “ hey genie let me see your arm you got to try this” Dave helped the Genie and gave him a shot. Dave and the Genie had never been so high in there entire life they were doing hot rails slamming in each other's jugular vein for the next three days until the whole bag was done. At this point, even the genie was showing visible signs of being on a bender and not sleeping for the past whole week. “ Alright Dave its been one hell of a week, but that was your third wish and it's time for me to go” the genie began to leave and walk towards the door when he stopped, look back over shoulder at Dave, and said, “Hey Dave how about one more wish?”
