“Who’s going to do something about it?”
“I think this time it is mine to ride.” Sarah said .
Somehow we all ended up in our bed, myself in the middle, Sarah on my right where she always slept and Ruth on my left.
Sarah was proprietorial, “Ruth, this time it is me and James, you can lie and watch but please let me have him.”
It was strange, my little sister watching and I assure you I could sense her gaze as she watched everything. I have to say my erection was magnificent, threesomes and incest were a real turn-on.
Sarah straddled me, guiding my cock into her pussy. Lifting herself up until only the tip of my cock-head was in contact with her nether lips — lowering herself until our pubic bones met and the tip of my cock kissed her cervix. Soon I was ready to cum, holding back waiting for Sarah to reach the same point. We had been together so long that we instinctively knew one another’s bodies and minds.
Three fast up down movements, I thought she was about to cum. She lifted herself, my cock was free. I felt her fingers guiding my cock. As she sank down very quickly Sarah gasped. “There my love. You have my arse.”
“Another surprise.” This was not an understatement on my part, usually despite my pleading and wheedling, Sarah would rarely agree to anal intercourse. She claimed it hurt too much. Now she was impaling herself with vigour, and she had only just been buggered. — Usually if I’d buggered her so forcefully, thrusting into her without pauses, she would have protested.
“A pleasant one I hope.”
“I have always been an arse man, and your arse is lovely.” I replied lifting my hips so as to thrust into her.
Now we were both moving — short fast frantic strokes more urgent as we drove towards another orgasm each of us aware of the other. Then it happened, we both came, bodies trembling.
“Does having it up your arse really make you cum?” Ruth asked.
“I told you shut-up this is me and James time.” Sarah snapped at her.
“I was only ….”
“Shush little sister.” I said. “You are fucking fantastic.” I said to Sarah.
“I know and don’t you forget it.”
With a soft plop my softening cock fell from Sarah’s arse. “God I love it when I feel full,” Sarah said, “Now I’m ready to sleep.”
“Yep I feel about right for sleep too.” I agreed.
“What about me — I’m still buzzing.”
“Ruth get some sleep you won’t get any tomorrow night,” Sarah said in her big sister or mommy’s voice.
I awoke on Saturday morning,sun streaming through the window — the curtains had been drawn back. On the pillow I found a note. “Hi Sleepyhead, We have gone riding be back about noon. Love S & R xxxxxx” I looked at the clock, it read eleven thirty. They should be back at about noon, so it was time to have a shower then get dressed. I knew it was only a few hours and we would all be back in bed. The first thought of fisting Ruth’s virgin pussy and my cock was rising to the occasion.
All afternoon the atmosphere in the house was one of rising tension. If Ruth laughed Sarah giggled, if Sarah laughed Ruth would giggle. At one point in the afternoon both of them disappeared into the bedroom. The look Sarah gave me, locked the door as securely as if she had barred the door.
