I thought jerking off to sexy images of my Nanna were hot. Until she sucked my dick. Then we fucked. And then she requested my big cock in her bum! I never did anything let alone put my penis in a womans bum! Wow. After moisturizing her sphincter; first by tongue bathing it and then with lotion, she directed me, slowing and surely. She began panting and as I was balls deep in her rectum she began shivering and shaking in orgasm. She pleaded and pleaded for me to take her and fill her with my seed, which I did. I withdrew my shaft with a slithering pop and my cum oozed from her hole. She exclaimed that we definitely will be doing THAT again!
