Greg gave a low seductive laugh at how playful Theo was behaving, "If you fail, well..then it will be all of my fault I suppose, especially if I am to wash all of you," he said, as he started again.
The wet cloth washed over Theo's chest and down his back, and Greg moved it into Theo's underthings, rubbing the back of each buttock. He let his fingers find the crease between each, and Greg cleaned all of Theo, knowing that he would be the one to inspect that spot directly.
"Kiss," Greg said as he moved them, this time towards a set of stairs that led into the bathtub. He set Theo down on the stair, and moved back, so that Greg could move the washcloth between them, starting to clean where they had been pressing against each other.
