Oil Change

If you do drugs and need to pass ampiss test, a P-vac isn't an option and you need clean urine, you'll need to do an oil change. An oil change is when you stick a sterile tube in your urethra until urine naturally comes out. Next take a syringe full of clean urine and inject it into the tube. There, your oil is changed.

The test is tomorrow, we'll never pass unless we do oil changes.

First you get on one of the carts you use to go under a car. You roll under your girl when shes on her period, heavy flow. You take out the old tampon and if blood gets on you thats ok your doing your job right. Clean her up, put in a new tampon, roll out from under her and give her a thumbs up.

Aaron gave his girl a great oil change last weekend.
