This is the third part of my story. Reading the other two parts is important to set up this part of my story.
*****
My journey into submission was proceeding. I submitted to Karen and her Mom several times a month during my senior year at the midwestern university in the late 1970s. We would get together at the apartment they shared. Our times together became more intense and I became even more comfortable submitting completely to Karen and her mother.
We would always begin by being greeted at the front door by Karen and her Mom. Karen would give me a kiss and then I would be ordered to strip. I was always to be naked in their presence. They created a shelf in the front hall closet for me to place my clothes. I would then walk over to the couch where they would both be sitting. The couch faced away from the door and towards the large window which looked out over the city. I would place myself across their laps and Karen's mom would begin the spanking. Karen's mom did most of the spanking and preferred to use her strong hands. She only used the nearby paddle when her hand tired. The spanking always would bring me to tears and I would just lie there and take it.
They always used their strap-ons to fuck my ass. Karen's mom took the lead. She gradually expanded my asshole by using lubricant and larger devices. I would wear a butt plug during the remainder of our time together. They would thoroughly fuck my ass. I was always gagged and could do nothing but take it. I grew to crave the feeling of having my ass filled by their cocks. All the back and forth motion of the fucking was hard to take but I did it for them. Karen's Mom seemed to get more into the fucking then Karen did but they both used my ass as they pleased.
I became an expert in using my mouth to pleasure their pussies and bring them to orgasm. They taught me many positions. Karen's Mom preferred to ride my face and Karen seemed to like it most when I laid between her legs on her bed. Karen would cum with loud moans and Karen's Mom would have multiple intense orgasms. During our last time together they taught me to pleasure them from behind. They got on their hands and knees and I was taught to first lick their ass and then pussy until they were pleasured. I became as good eating their asses as I was eating their pussies.
