Speaking of supercest... Clark discovers Jon and Conner kissing and laughing clearly unaware that it's wrong with Conner's hands around his little brother's waist. He stops them and when they think he's going to scold them he just orders them to stand in front of him so they don't "go too far" or do anything inappropriate for their age. Even though Clark doesn't say anything when Jon massages his brother's clothed penis or climbs onto his lap to rub it or when Conner puts his hand under Jon's shirt to grope his breasts, instead they seem to be putting on a show for Dad especially judging by the looks they give him smiling when Clark swallows hard and squirms to hide his erection.
