Josh had never been well-endowed, and had never felt self-conscious about it. A born submissive bottom, Josh had always been proud of his thick bubbly ass that jutted out several inches from his waist.
He didn't have to compare dick sizes to know his balls were the smallest in the room and getting smaller. He was practically falling out of his clothes at this point. Paul had never stopped shrinking during this period, but Josh was quickly shooting towards his size as he watched his boyfriend literally sucking his own brother's shrinking cock.
If Paul was closing in on two and a half feet tall, then Josh realized with a start he was coming down to less than four feet. Mike beckoned him over with an inviting hand, sucking on Paul's tiny dick while reaching over to grab Josh's own diminished hard on to begin jerking him. Josh threw back his head, moaning as he felt the world rapidly expand. He looked over and saw Paul there, helpless before Mike's ministrations.
They were eye-level.
Then Josh was looking up. He was less than two feet tall, and shrinking so very fast.
He almost came then and there.
