Having finished my ablutions I had slipped the hose inside me and filled my bowels with lovely warm water. I held it inside me as I leant back against...the wall and massaged my tummy. When I felt that I couldn’t stand the pressure, I had transferred to the toilet seat and voided myself of the water, washing my insides perfectly clean for the anticipated anal fun that would surely occur later in the evening. It was lucky that I had as there were a few little nuggets of shit that had rinsed into. During our short winter here, I had received a long-distance inter-system message. It was from my sister Aurelia, whom I had not seen for almost twenty years. The message stated she was onboard a starship transport and would arrive here to Rigel VI in a few weeks. She hoped I would meet her on arrival, and wanted to stay with me until she found some work and could afford her own place.My sister was a couple of years older than me, fairly plain looking as I remembered. She had looked after me. His fingers rested quietly on the back of my mid thigh, the knowledge of his intent, touching me intimately, was a bold declaration to my womanhood, I knew he had been masturbating himself between his wife and I, so I knew he was prepared, and I was his intended victim.I was exciting myself, magnifying the events for my own sexual gratification, my last sexual relations with my husband, was over a year back, so this intrusion was preparing causing my own body to respond in preparedness, I was. I slapped her face. "This is what you want cunt! You want to be ****d and abused." Yes Dave! Yes! Your mother wants to be treated like a slut," she said, "Fuck me Dave! Aaaahhhh! God! Fuck me hard."I continued slapping my mother's face and milking her tits while abusing her. I urged the man again.. "Fuck the cunt! Fuck my mother!" He drove his huge member up her cunt and suddenly froze. I knew he was cumming. I grabbed mom's tits and squeezed them tight as the man shot his load into my mother's.
