Το hands-free jacking στην αντλία μεγαλώνει από κουτσό σε πλήρες μέγεθος

The tube is like a mouth, connected to a pump, sucking the cock from limp to full size. The expanding and relaxing of the shaft within the vacuum tube, feels like it is being jacked or sucked. Notice the cum marks on the inside of the receptacle, evidence of pleasure.
