I walked up to her and saw that Stephen was spanking her hard on her now red ass. She yelped in pain and tears threatened to form in her eyes. But I i...nored them, kissed her on her forehead and told her I was leaving for work and that Stephen was in charge.She looked back at me with a glow in her teary eyes and said: “Don’t worry daddy, I’m grandpas little submissive slut. I’ll do whatever he wants me to do.” With that, I gave a small nod to my hated father-in-law and left for work as Stephen’s. I stood, shucked my clothes and followed them into the bedroom.The room was huge, dominated by a California King-size four poster bed. Mirrors on all four walls and one encased in the canopy frame. Noticing my reaction, Jane said, "Yes, I'm an unabashed hedonist. And I love to watch! So, why don't you two go at it while I entertain myself?"Candi immediately said, "No! We do this all the time. You two haven't mated in 40 years, and I want to watch you." Only if you agree to participate!" Jane. I did so, kneeling on the sofa with my elbows resting on the back, his right leg up touching mine as he braced himself with his other foot on the floor and held me around the waist. His stiff cock pushed once more against my arse, which had closed a little in the few seconds we'd changed positions, forcing it inside steadily. I moaned as it slid through my slightly soar anus, the pressure on my prostate quite delicious, until I felt the front of his thighs touching my buttocks. He pulled almost. Turningthe speed onto setting three of seven, it was enough to keep mestimulated and permanently hard for a few hours, without bringing me to aclimax.I could easily have stopped at that point, but with all that I hadbrought with me I knew it was going to get a lot better, I just hoped inwould be as good as I had been hoping for these past couple of weekssince I knew I would be staying away. Every spare moment since then I hadbeen unable to stop imagining and fantasising about it, I do so hope.
