Dereck kept adjusting his crotch through Matt, and Matt found himself concentrating on the shape, scent, texture and taste of Dereck's manhood. Matt was embarrassed, and concerned, maybe Dereck didn't know that Matt was the zentai - or maybe he did. Dereck left his room still adjusting himself. He went downstairs, and then down into the basement. There was a home gym down there and big screen TV. Dereck flicked on the TV and climbed up on the treadmill. He started running while the TV blared. In a few minutes, Matt was tasting sweat and feeling the heat generated by Dereck's body increase. He realized how the zentai suit trapped the sweat and heat. Dereck was in good shape, but whenever he and Dereck were in the basement, they only watched TV, apparently, Dereck liked to workout in private? He always said he wasn't dressed to workout when Matt had asked. Maybe he only worked out wearing zentai? It was amazing feeling Dereck's muscles moving up and down inside him. Matt soon lost track of time as his fabric body explored every movement, every nook and cranny of Dereck's body. Only after Dereck reached behind and pulled the spandex out of his butt crack did Matt realize he had been giving Dereck a wedgie. After two hours on the treadmill, Dereck slowed down, and cooled off. He filled a glass of water and drank it right through the zentai hood. It was weirdly refreshing and erotic, as Matt felt both the glass rim and Dereck's lips press against him. Cold cool water gushed through him and down Dereck's throat. He must've drank 20 or 30 ounces. Then he started pumping iron.
All this movement, all this stretching was making Matt sore. He thought he had been in good shape. Now he knew better. After about an hour of powerlifting, some more water, Dereck turned some controls behind a secret door in the paneling. He grabbed his iPhone and bottle of water. He opened the panel. Damn, Dereck had his own sauna? Dereck lay down on the warm wooden bench, and flipped on his music in speaker mode. Matt enjoyed being still finally. The tunes were good too. Without all the movement, Matt found himself concentrating on the sweat, the stench, and warm body inside him.
