"Marcia," responded Lord Jacob. "When a woman wears the uniform that you are accustomed to see, she is considered to be in the service of the Lady of the manor, and cannot be touched by another man, including her own husband. Although this does not protect her if a man sees her panties.
"Brenda and Sylvia?" he said to get the other women's attention. "Run along, Roberta will be joining you in a little while."
After they had left, Lord Jacob reached out with his left hand. Roberta was still standing right next to him, so he had no trouble reaching under her uniform. To say he reached under her uniform is a bit of an over statement. The hemline of her skirt was at her crotch, so it offered no impediment to his hand as he reached between her legs.
When Roberta saw his hand coming she slid her right foot over to give him easy access, then grabbed her elbows behind her back. As Lord Jacob began slowly stroking the crotch of her panties, Roberta closed her eyes, and allowed her head to drop back slightly. Everyone in the room could clearly see that this woman was greatly enjoying the attention she was receiving.
