My mate built a new tank and it needed testing. He wanted me dressed in a rubber vest, briefs, and hood, with heavy restraints locking my wrists to my calves. I get three brutal green tankings, helpless under the goo and not knowing when the next load is gonna drop. After all the tankings I get set free to play with my dick. I keep filling the hood and putting it back on, letting the slime drip down me until I cum hard into the goo.
