We dressed in our school uniforms as Grandma had suggested then wescampered down to breakfast. By nine we were on the way into town andsoon we were al...l tumbling out of the car into the car park. "Right girls," declared grandma, "We haven't got time to waste justwindow shopping. We have to get Petra's school uniform first then we canindulge ourselves. Right quick march everybody."Grandma had been an army nurse and knew how to organise a platoon. Shehad us well drilled and we fell into. “I’ll deal with YOU later!” I laughed.“Ooooh! Please! Promise?” she said saucily.“I think I’m going to borrow Elyse’s flogger!” I threatened.“I think we should!” Kara smirked, then ducked as I threw a wet dishtowel at her.“Are you three going to tease me mercilessly about this?” I sighed.“Only until we come to some decision,” Kara said, popping back around the door frame. “You know how complicated this is.”I nodded, “I do. Now, can we PLEASE make dinner?”“You should probably let us, Kara,”. I could smell her it, the aroma filled my nostrils and the idea that she would soon be eating her own shit off my cock was empowering me. I could no longer hold back. My pace quickened, becoming almost frantic. Both my hands now gripped her hair, her head pulled back and sounds of pain and anguish poured from her mouth, my hips were beating her, pounding her, then it began and my cock started to pulsate, pouring my cum into my dear sisters ass and all too soon it was over and I pulled my sweaty. Shortly afterwatrds,the car vibrated as the engine was started, and Steve was aware of thesensation of movement.As he lay there, his mind a blur, he had no idea where he was going orwhy. He noticed the liquid feed had stopped and was then aware of soundsfrom the ear buds. A sweet gentle music with undertones of a feint beatand soft quiet voices.The combination of the liquid, sounds and the movement soon caused Steveto fall asleep.The full bladder, and his relaxed state caused Steve to wet.
