The illusory women that Lucifer cast are still petting, caressing, but their purpose is more or less only to pin down Gabriel's arms, keep him from resisting or getting grabby. Their hands are eager and exploring, but they don't explore the way that Lucifer does, licking a stripe against Gabriel's cock before engulfing it in the warmth of his mouth. His hands urged Gabriel's legs higher, inviting him to wrap them around his back, even--it would make the next part easier.
