Things were a bit easier, more relaxed after our tea time love making session. Dad stayed dressed up for a while and we had a little giggle, all of us. I was pleased. It felt that we'd made some progress, breaking down the barriers of their moral reserve.
After I had gone to bed I heard them in their bedroom. Dad was obviously giving Mum a good seeing to, probably still dressed up in his little girl outfit. I was amazed that a man of his age was still had the sexual energy and I was so proud of him.
I slipped my hand into my panties and stroked myself to sleep.
I woke to my alarm firing off telling me another work day was in store. Images of the previous evening flooded into my head and I started to feel horny again. When was I not.
I heard Mum get up and go to the bathroom. Mum always got up first.
I tried to put my feelings to one side and got up to get ready. As I was slipping off my knickers I remembered something from last night and a very naughty thought crept into my head. I pulled my pants back up again, took a clean pair out of my drawer and slipped out of my room and headed across the hall to my parents bedroom.
I knocked and went straight in. Dad was still in bed and looked a little surprised when I came in.
"Sarah, what's up, darling?" He asked putting down a book he was reading.
"Nothing, Daddy. Just thought I'd bring you a little present." I smiled.
I pulled my hand from behind my back and dangled my clean silky knickers off the end of my finger.
Dad looked shocked.
"Sarah, really. There's no need .. I mean it's only 7 o'clock and Mum's only in the next room." He protested.
"Come on Daddy, don't be silly." I chided playfully. "It really turned me on when Mum said you liked to play with your lovely stiff cock with my knickers. And besides why should Mum get all the fun?"
He gave me that admonishing look. The one he always gave me when I was naughty as a child.
"Anyway these," I said swinging my clean knickers around on my finger, βare not your present.β I threw him my knickers which he deftly caught while still looking at me. I lifted up my oversized t-shirt up to my waist, "These are."
I paused for dramatic effect, letting him take in the sight of my white cotton knickers.
"I've had these on all night, Daddy, and I've been very naughty. When I heard you and Mum having sex I just had to play with myself while I was wearing them."
Dad's face was a picture. I could see him swallow hard and I even heard him groan a little just picturing me rubbing myself off into my knickers. I was shaking a little myself and my stiffening nipples I could feel almost burning through my t-shirt.
"Would you like to play with my panties, Daddy?" I teased.
There was a pause while Dad tried to get his voice working. "Yes, Sarah. Please." He managed.
I smiled and reached under my t-shirt and slipped them off, not letting him see my pussy. Not yet anyway. I tossed him the small cotton undies and he held them in his hand as if not sure what to do with them.
"Do you want to just hold them Daddy or do you want to hold them to your face and sniff them?" I continued to tease him and treat him like a small boy.
