"Now you can see, for a while," Lily said as she removed the sleep mask.
I couldn't see. My face was covered with layers of petticoat frills extending over the top of my head and an edge of pastel blue skirt hem beyond that. Lily pulled the material down so I could look up to the ceiling mirror.
From my hips to my head Lily had fitted me into a strapless blue mermaid dress. I was sheathed tightly above my shoulders then the dress splayed in a wide hem over a very frilly bottom of the mermaid petticoat.
"There you are, Paul," Lily said, "You're an inverted mermaid. Your top half is a fish; the bottom a man, accessible for me. I only need a couple more refinements."
Lily reached under her ball gown, removed her panties and stuffed them into my mouth. She took a long scarf off the bedside table before winding it around my head, over my mouth and gagging me. Once she had finished she let go of the petticoat frills and skirt hem. They blindfolded me. Finally she took a white satin scarf, stuffed the frills and skirt inside as she used the scarf to hood my head completely. No matter how I shook my head I couldn't displace the petticoat layers hugging my head. I could still breathe, with Lily's perfume stronger than before.
My erection was standing proud as Lily's skirts and petticoats slid up my legs as she straddled me. I flinched as her hand gradually fed it inside her warm and expectant cleft.
As she started to move up and down it took me considerable effort to hang on. She became more active and insisted until I felt I couldn't restrain myself any longer. Lily knew just what my limits are. As I reached a climax, Lily's hands pressed the scarf hood and petticoat frills across my face tightly. I shuddered in release, shoving my hips upward to thrust myself deep into her.
After I slumped, Lily gently removed the scarf hood, pulled the frills and mermaid skirt away and, removed the panty gag to allow me to pant for breath. She kept my diminished erection in her until I recovered and we could make love slowly and gently again with my head smothered by the mermaid's frills held in place by Lily's hands.
She released me from my bondage in the early hours before sleeping on my shoulder.
Shortly before dawn she lifted the skirt of her ball gown to straddle me again. This time she had stuffed my head and shoulders up inside the mermaid dress and petticoat, pulling it below my waist. The lower dress above the frills constricted my arms nearly as tightly as the wrist restraint had done. My head was lost in the layers of the petticoat and dress. Once I had satisfied her again, she left me, sleeping but loosely confined in that dress while she went off to make breakfast for us. I managed to wriggle out to join her when she called to say our meal was ready.
Lily's inverted mermaid was a successful addition to our bedroom games.
