An increasingly stale relationship had led to Steven and Carol drifting further apart. An added problem was Steven's unspoken and unshared desire for Carol to dominate him sexually. There was no way that he could broach the subject with her. She would think that she was living with some sort of 'pervert'.
Her upbringing and school days had been very strict. Wild sex, in her view, was her on top.
It hadn't been enough for Steven and in his desire to be dominated he had approached a dominatrix who would satisy his submissive desires.
His visits to Lucy had helped make the relationship with Carol sustainable. However, when the day arrived when Carol asked about 'Lucy', he realised that things were about to change for them all.
