Greg came up out of the water and he tried to move the towel so it draped around Theo's body before he leaned down to kiss Theo's stomach. His hand moved across Theo's skin as his mouth moved, kissing and sucking at Theo's stomach and down to his exposed hip bones.
Greg's hands stroked up and down and then brushed across Theo's groin even as he kissed the skin on his hip, not far from it. He was moving down, kissing, his mouth hot against the cool skin; he wanted to suck Theo all over. It would have been the first time since he had come home to Hogwarts. And Greg was oblivious to the show he was giving to the prying eyes around them.
