A tingle came to life between her legs. Who was he? What was he doing here? Who was he talking to? She felt a strong desire to find out, and decided s...e had to at least see what he looked like. Putting on her best casual demeanor to hide her speeding heart, she strolled casually around the corner. Out of the corner of her eye, she saw him, his back towards her, a hand in his back pocket, the other holding the cell to his ear. Dark hair, medium build, his clothes a bit rumpled. He was nothing. I went to get on my knees but she stopped me. She said she is going to ride my cock. I stayed on my back and she got on top of me and started rubbing up and down on my body with hers. Every time she slid down my cock went into her pussy a little more each time. She was doing what Emily and I did when we fucked each other. I asked her who taught her how to fuck like this, knowing the answer, she told me Emily did. She slid down further and further onto my cock. She was teasing me. When she slid. It’s a dark grey bra, thong and suspenders set. She is also wearing nude stockings and has on her sexy four-inch heels. She is standing up, leaning back against the doorway to the living room. She is clearly in a state of full arousal and just seeing her like that turns me on too.“Baby, I have been waiting for all day to get home. I have been so horny, and I need you to make love to your mamma.”I strip off, exposing my body to her and my full hardness. She walks over to me, kissing me full on. But we can look, you know better than I.” Robin said, thinking about the short skirts, and the black corset like top as well as one of the not quite opaque tops.As she got clean, Robin perked up a bit, and returning the favor, began to clean her sister, ensuring that all remains of paint were gone from their bodies. Having her stand up to get the last of it from her sister’s backside, and then around in front, she gazed at her sister’s sex, looking up briefly, before moving her head forward,.
