I only had to make sure that the top-rung was high enough for me to stand on and reach high enough to give me leverage. But how do you build a rope-la...der? I knew how it looked and I had climbed one during gymnastics at school. But I had never looked how they were constructed. I had to go to the library.I soon found out how to make the rope-ladder and went back and made one. Now I was ready for my teacher! But since I was here already I decided that I should check on Debbie.As soon as I was. For the first time in her life she was being fucked!Serena watched with wide eyes as the black man pushed and pulled the giant cock in and out of her mom. She licked her lips as she could see the pussy juices shining on the dark chocolate colored cock. Then she turned bright red as she thought about her perverse habit of licking her juices off her fingers when she masturbated. Suddenly she felt the black man looking at her."You like seeing me fuck mama! Let me show you something! Come closer!". “OOOHHH” she said. She lifted my t-shirt over my head and I helped her remove it whilst slowly moving in and out of her. She slid her hands up my back and pulled me towards her so I pushed my cock in, a little further. She dug her nails into my back and scratched me, which is a big turn on for me, so I pushed all the way in to my balls. “Oh shit.” She said as I bottomed out. “Oh give it to me. Please fuck me and give me your spunk.” I started to pick up speed, she met me with synchronized. He just stood there silently, in complete shock as his eyes glanced at my tits then back to my spasming pussy."I'm so sorry doctor." I deviously said smiling at him as I removed my hands from my breast. I continued, "You have no idea how much I needed that. Thank you." I panted as I noticed the obvious bulge in Dr. Nelson's pants."It looks like you could use some relief of your own." I sexually said glancing down at his hard cock?I scooted my ass lower on the exam table, causing my legs to.
