After a while of tasting each other out, Lith felt it was time to switch. To do that, he simply tapped a few times on Lilith's big butt and gestured to her to get off.
Lilith did as asked and as Lith was about to get in between her legs again, his gaze suddenly fell on Luna who was standing in one corner of the room, maintaining a professional neutral face and waiting for further orders.
Lith was so absorbed in his pleasure that he totally forgot about her. As for Lilith, she was used to Luna's presence like this and didn't feel much about it.
Looking at Luna and also having his own mother in the same room, Lith suddenly remembered that during the marriage ceremonies, identifying the bride one to be precise, she had mentioned that she was down for a lot of rough play if Luna was there.
Lith couldn't remember if she said Luna or the maids in general, but taking Luna would be a safe bet, so he assumed just that.
