Saved by the knock?

The feeling of Tamano's soft, fluffy tail creeping up your leg is almost too much to bear. The grin on her face as she looks on to you, the smell of her soft, warm inviting fragrance. You nearly lose yourself in the sweetness. You pull your head together as you still don't know anything about this whole servant or Grail War thing. "Wait, what do you mean about the Grail War? And what do you mean by that you're my servant? Or even wife for that matter?"

Tamano turns her head. "Uwah, looks like we'll have to wait, dearest." A faint image of Tohsaka appears next to Caster, "This girl is at your door. Shall I dispose of her so I can tend to you some more, my dearest?" "Tohsaka!?!" You exclaim in question. You slip out of Tamano's tail and bed to get your feet on the floor. "I'd better go see what she wants." You say. Caster sighs, "How sad. I was hoping to spend some more time together. Just exit out the door to your right, and do put your clothes on first."

You look down to see your nakedness and feel the blood rush to your face as you blush in embarrassment. You quickly move to cover your private areas, which elicits a stifled laugh from Caster. "You don't have to hide from me, my dearest husband. Please, relax." You sigh and quickly put your clothes on, much to Caster's dismay.

You walk to the door Caster mentioned with her following you, and open it. You are amazed to see the normal entrance to where your room sits in your residence. An irritated knocking bangs on the door. "If you're in there, you'd better hurry up and answer!" Rin shouts. It'd be inadvisable to keep her waiting any longer.
