Sliding and slipping

Silently, Tony reached for Sofia's hand, which she offered. Closing the nursery door, he led her to her bedroom which was furthest from where Marcia slept. He closed the door.

Sofia didn't say a word, She just disengaged her hand, sliding the straps of her nightdress off her shoulders. one by one, almost in slow-motion. The garment slipped gently to the floor. A nice seductive touch, but one that wouldn't 'make the cut' as Tony spoiled it by lunging at her naked body as if it too might slip away.

Then a mere mechanical process with female sound effects.
