I was surprised that the thought of having sex with this guy turned me on and I became slightly erect. The train cut into a turn and he was pushed int... me again and I reached down to stop him from falling too far and grabbed his waist as I did I felt him grind his zippered ass right into my crotch. Since I was wearing dress pants it was easy for him to tell that I was turned on and I saw him look over his shoulder and give me a smile. He grabbed me by the free hand and held it on his hip while. ‘Black bra?’ I thought. ‘Interesting.’ Only for a minute, of course. Then my thoughts turned to the two heavenly bodies that it concealed so well, yet so poorly at the same time. Snapping open the clasp, my hands slowly, but knowingly brought it off of her body. Her nipples, fully exposed now to the cold, grew erect, and beckoned for me to play with them. I willingly obliged. As I kissed her again, my fingertips gently assaulted her tits, twisting, tugging, rubbing… It all molded gently. There was a new one there called, “I LUV MY DADDY”. Terrified, she looked in it and saw picture after picture of her and her father hugging or posing together.“My sweet girl, you must be wondering what the punishment is. I merely thought your time with your father was so sweet and touching. Now you’re task is simple. You’re going to touch yourself while you think about your loving doting daddy. You must look at his picture and imagine him touching you, and you must want it. While you’re doing. He spread his legs wider, and I pulled my pants down to my ankles. Backing up between his spread legs and facing away from him. I spit on my fingers and wet my butt, then his dick. Trying to help, he spread my cheeks apart, and I guided his dick to my hole. I lined everything up, and started lowering myself down. I remember being nervous, and hoping it didn't hurt like last time. I also remember my dick was rock hard during this whole time. I felt his tip touch my ass, and eased down. .
