My ass was being pounded well. My Grandmother was cumming so hard I could feel her muscles clamping down on my arms. Then I felt Grandpa's dick swell ...nd I knew he was going to fill my ass again with his hot sperm. The same sperm that had given my mother life. Grandpa rammed his dick deep into my ass. I could feel his pubic hairs on my crack. Then I felt his hot sperm rush deep into my bowels. I came almost immediatly. It was one of the best orgasm I had had. I could feel my bowels. It’s not like I can have any fun by myself tied up, I couldn't even play with myself and get a head start. I looked around the room for a clue as to what was next, what I supposed to do other than wait for his return. Was that it, he was the knight in shining armour coming to rescue the damsel in distress, well damsel in bondage anyway. I looked down at my naked body and on closer inspection realised he’d placed a new gold chain around my neck, with a small silver key attached to it. That must. There is a cook off time before the turret takes off ... but, you know the movies ... if it’s not action right now it’s on the cutting room floor. Usually the crew is already dead from metal splatter.The turret rests on a platform and it’s the platform that rotates. It’s the weight of the turret that keeps it from falling off. The turret gears are on the floor of the tank and not on the turret edge. I was planning on a heavy steel disk fitting on the turret hole. I wanted the skyhook bolted to. But the guy was indeed not so much into it and retreated. The one I was sucking wanted to take me so he took his spot and sticked his dick in me while Mister Friendly gave me his cock to suck. Maybe 5 guys were looking at us (instead of the movie) and I was hoping it would start the gangbanded I always fantasized about. But when the two guys released their loads nobody took their spots. I stayed a minute or two and then left the room. I though later on that I should have been more provocative.
