I need to give a description.
Luigi deepens the kiss, cutting off Mario's babbling. He is aroused by how deep he is inside his brother, feeling his inner walls expanding and clenching around his meat. Mario whines and shuts his eyes, not wanting to look at his brother any longer. He can feel Luigi's cock massaging tender spots inside of him, causing his own cock to twitch and harden even more. He is in unwavering shock from what is happening to him, unable to function normall. He is confused, hurt and... frightened for the most part. Luigi grips the Man's cock yet again, pumping it brutally, knowing he shall never forget this day, and nor especially will Mario. He breaks the kiss, panting for air though continuing with his harsh thrusts.
