Jason and Andrew left this one to Ben and David and went off to do some of their own converting. Ben and David hid for a while in the shed in the backyard, occasionally kissing each other and masturbating. Once their dad Michael got home, he assumed they were probably out partying with some girls and went to bed shortly after having dinner alone. At midnight, David and Ben quietly entered the house. They tip toed into their dad's room.
Their dad lay fast asleep in his big king sized bed. He was sleeping naked as their dad refused to wear pyjamas or underwear to bed. His clothes were draped over a chair at the end of the bed. Ben opened hs drawers and took out every piece of clothing he owned, except for one pair of white briefs. David gathered these clothes and threw them all out...his dad wouldn't be needing them soon enough. Meanwhile, Ben took the one pair of white underpants to the bathroom and jacked off all over them. Instantly, the underwear absorbed it and turned into a dry tight red speedo. He crept back into his dad's room and put them back in his drawers, and then went back to the shed.
The next morning Michael got up. Odd, he thought to himself. Where were the clothes he had worn yesterday? He moved over to his closet and opened it up. Nothing. Panicking, he began to fling open all of the drawers. Nothing...nothing...nothing...noth...wait a minute, something WAS in this one, hidden in the corner. It was a red speedo. Strange, he could have sworn he never used to own a speedo, and it certainly wouldn't have been that tight or that color. He glanced around the room, as if to make sure no one was watching as he refused to go anywhere in his house besides his room naked, but he didn't notice his former sons watching through his window. He placed one leg into the speedo and then something clicked. As his legs made contact with the material he got an instant boner. His eyes fluttered and a smile passed over his lips. He put the other leg in and slowly pulled it up his thighs until it made contact with his cock and balls.
The second they hit he fell to the ground squirming. His short beard faded away with all of his leg and chest hair. He felt some of the wrinkles on his skin smooth out and then he watched his chest develop some nice abs. He watched as his skin darkened a little as it became more tanned and then he saw a picture of his sons on his bed side table. Jeez they were hot, he thought to himself. Then he turned to the door, and there they were standing in their new forms rubbing their hard ons through their tight red speedos. They ran at each other and began to lick each all over. David bgan to tongue his former father whilst Ben began to rub his balls through the speedo. Then they all clambered into the bed and began to have hot sex together, but they left their speedos on for the whole thing as it made them feel hotter. After an hour or so of continuous gay sex, they decided it was time they initialized a new member to their growing army of the speedo guys.
