This was exactly what the girl had most dreaded all her life and had scrupulously avoided until now: lovemaking without emotion or love. She knew that she had crossed the forbidden boundary, but she proceeded across it without objections and as a full participant; only somewhere, far off in a corner of her consciousness, did she feel horror at the thought that she had never known such pleasure, never so much pleasure as at this moment--beyond that boundary.
