Serena practices the mysteries of Tantra. She guides and he follows. He trusts her that she will take him to ecstasy.
And she does - the Tantra way. Within the candle lit space they meet and touch. Her voice comes as though from far away as she strokes him all over. As the skilful ritual goes on Serena uses her whole body to make contact. Even her flowing hair is part of the intimate sharing.
This is communication at the deepest level. No words are necessary. His pleasure swells. There comes a time - the right time - when it must reach its climax.
