Solo orgasm with plastic bag in the shower

I put a stocking on my head, then a plastic bag, and go into the shower, at first the water is cold, then warmer and hot, I start masturbating, there is not enough air, I breathe often. I stand up and bring myself to orgasm, turn off the shower and sit down to squirt, juice flowing down my arms. I have almost no strength, but suddenly a small hole forms on the bag, so I have more air now, and decide on the third round!
