There I was with four black men. I had always dreamed of being taken by a group of black guys and now it was going to happen. Everyone stripped down a...d soon I was looking at three more big beautiful cocks. All were soft but still quite large. I went to them and took each into my mouth. I had their cocks hard in no time at all. Fully hard they were eight or nine inches in length. Two guys had thick cocks and one was average in girth. We got on the bed and started to kiss and touch each other.. The door to the roof was closed, but the lock had been busted by Joe, the previous day. It was a simple matter for them to get onto the roof.The roof was flat with the stairwell and a large air conditioner unit standing up like mesas in the desert. Off to the side was a ladder that led down to the roof of the building next door. That would be how they would have to leave once the office building had been locked up for the night.The pair moved over to the air conditioner unit and sat down facing. Her breasts were huge, 38 to 40 DD cups depending on the time of the month, and her nipples were very prominent, protruding through any garment she wore. She had long, dark hair and medium brown eyes, a nicely turned nose and round, rosy cheeks and had an ability to go from a seeming total airhead ditz to a sex bomb in just a head turn. She would become very dominant sexually towards me from the very instant we met. I will be honest, she could get me to do anything she wanted. The first time I. The teasing of her nipples brushing my throbbing cock had turned my cockhead purple, and my balls were engorged and tightening. I told Sherrie to stop teasing me with her nipples and use her lips and tongue on my cock. She started to reach for my cock with her hands, and I slapped her ass and told her "no hands!". With her nastiest look, she smiled as said "I'm gonna' fuck you with my mouth, and make you cum!", and I slapped her again. She shifted her position to allow me to continue spanking.
