He gradually increased the tempo until he was feverishly jacking himself off. He was thinking of Lisa the whole time, wishing she was riding his cock...like a maniac. Just then the door to his room opened and Lisa stepped in. James froze with his stiff cock in hand. She approached the bed wearing only her black robe."Don't stop baby, I want to see you cum," untying the sash at her waist and allowing her robe to fall open.James was mortified that his aunt walked in on him but he was so turned. After a while, I took the condoms out of my pocket and gave it to her.She didn’t know how to put it. I guided her. And she rolled it up around my dick. She came on top of me while I was still lying. She put my cock inside her pussy. She started jumping up and down moaning slightly. To control the sounds, I pulled her to me and started kissing while she was moving front and back on my dick.After a few strokes, I cum inside the condom. We took a break while kissing each other and foreplay. After. It was as much as she could do to get her fingers around it. “Sorry Dad, at least Mum was right!”“Right about what?”“I asked her if a man’s cock grew bigger as he got older. She advised yes, and if I come up against anyone with a cock as big as yours I should keep my legs firmly closed.”“She said that?”“Yep, and do you know I think she could be right, but I’m out to find out for myself!”“Find out for yourself?”“To true, I’m not going to waste what you yourself had started, I aim to find out. " I rolled her over and climbed on top of her body, straddling her. I started at her neck and began leaving little kisses along the entire length of her body. As I neared her cunt, I felt her tighten and moan in pleasure. I slowly gave her peckish kisses along the length of her inner thighs, teasing her cunt and making her squirm. She begged me to quit teasing her. So I gave in. I kissed her clit, and swirled it in my mouth with my tongue. I trailed my tongue slowly to her open, quivering.
