After our intense sex with each other we fell asleep in each others arms.
I awoke sometime later in the pitch blackness of night. I was lying on my side and felt something rubbing between the cheeks of my ass.
I reached down behind me and felt Brandon's cock rubbing on my ass. His cock head was wet with pre-cum as he worked it towards and against my fuck-hole.
Holding his cock I pressed the head against my rectum and pushed back with my ass.
Brandon produces a copious amount of pre-cum and that was all the lubricant we needed.
I was more than ready to receive his cock and have my grandson deposit his seed deep in me.
Suddenly the head popped past my sphincter muscle. I could feel his mushroom knob begin to stretch and fill me as he gently pushed and slowly worked deeper into me.
Brandon's cock is about eight inches long and around five to six inches in circumference.
I have had many large cocks in me but none that filled me as completely as did Brandon's.
He slowly worked his cock as deep into me as it would go, then after holding it there for a few seconds he pulled back and began to slowly pump in and out. My hips began involuntarily pumping back against him. Meeting thrust with thrust.
Brandon fucked me for several minutes in this position and then somehow rolled me onto my back with my legs over his shoulders, while keeping his cock in me. He leaned down and our lips locked together as he slowly pumped in and out of me.
My grandson worked his arms under my shoulders and pulled me tight to him as we thrust against each other... him sliding his cock back and forth in me and me humping against him, riding his cock.
As he held me tightly against him I realized Brandon was not fucking me, he was making love to me. He gently slid in and out of my ass and I became more and more possessed by him and I finally succumbed to that possession.
I entered a state of nirvana, yet also felt Brandon gently making love to me. I started a crescendo of wave after wave of orgasms, each one more intense than the one before.
I lost track of time as I remained in nirvana and enjoyed the pleasures I was receiving at the hands of my grandson.
Brandon started pumping harder as I felt his cock twitch inside of me. He pushed in as deep as he could and held himself there as he started pumping his seed into me. I do not know how many squirts it took for him to empty his balls in me but I do remember feeling seven mighty pulses of his cock. After each time his cock squirted it would shrink a little in circumference then swell again as he prepared to shoot another stream of his seed.
I have been on the sissy side of the line for many years now, but this is the first time I have been totally possessed by a man. I knew, with a feeling of pride, that I had just became Brandon's sissy cum slut and I will be available to him at any time ...
Brandon let go of my legs and collapsed onto me with his cock still buried in me.
An immense feeling of pride in my grandson overcame me. I had often thought of my ass as being used like a cunt. But now I am thinking that my ass is a cunt and my grandson owns it any time he wants.
We lay in that position basking in the afterglow of our love making. We kissed deeply and when we broke our kiss Brandon rolled over off of me. We lay in each others arms for several minutes until I realized that Brandon was asleep.
I slipped out of bed and as I headed for the bathroom I felt Brandon's cum running down my legs. I sat on the toilet and drained as much of his cum as I could out of me and then took a hot shower.
When I returned to the bedroom I saw the sheets were soaking wet where Brandon and I had been and Brandon had rolled onto the far side of the bed. The side where Brandon and I had been was soaked with our combined sweat, precum and cum.
