She put more oil on me, and she let her hands roam all over me. It felt amazing and I would occasionally feel her tit as it brushed against me. She was making me so horny; my cock was actually aching. After she gave me a full top to bottom massage she said, “Turn over, it’s time for your front.” I turned over and my cock stood straight up. I looked at her and she was standing next to the bed naked. She bent over, dropped oil on my stomach and started to rub it in.
Mary said, “I don’t know whats making me wetter, these tight abs or your massive cock.” I just looked at her as she started on my shoulders, then on my chest and she made her way down to my abs. I was just enjoying the feeling as I watched her body bend and twist while she massaged me. She asked, “are you still ok?”
I said, “yeah, why wouldn’t I be?” She didn’t say anything tome, she just took her oily right hand and put it on her pussy. She actually poured a little more on it and made sure it was completely covered. Then she climbed on the bed and straddled me. She was sitting on my thighs looking at me. I said, “Mmmm, I really like this view.” Looking me right in the eye she reached down and started rubbing her clit while sitting on my legs.
My 51 year old sister was masturbating on me while I watched. She never touched me, she just kept playing with her pussy and she started to rub her nipples. She said, “I thought you might like to watch, was I right?” I nodded my head and just watched my sister play. Then she said, “you could play too, but just keep in mind, if you cum, that doesn’t mean we’re done.”
I said, “you could do it for me if you want.”
Mary said, “I don’t know, so far all we’ve done is watch each other?”
I said, “well since we’re only half siblings, maybe the half that’s not the same parent could do it for me.” She laughed so hard she actually took her hand off her pussy and put it on my chest.
When she finished laughing she said, “I’m so fucking high and horny right now I don’t know what to do.”
I said, “I can think of a few things to get rid of the horny part.”
She laughed and said, “Ok, tell this old broad, who also happens to be your big sister, exactly what you would do to help me, and while you’re telling me, I gonna keep playing.”
I said, “The first thing I would do would be to bend you over the arm of that chair and fuck you from behind, and when my dick gets tired, I would kneel down and use my tongue. Then finally I would have you sit on my abs and watch you make yourself cum all over them.” I guess that was a good answer because I heard “Ohhhhh” and suddenly my legs were getting wet. She was cuming all over me.
He face was contorted in beautiful cum look, damn she was so hot. Mt cock felt like it was going to explode, I needed to cum so bad. When she finished she pulled her wet hand away and smeared it all over my abs. The she said, “jerk yourself off all over me.”
I said, “Do it for me, pleeeese.” She grabbed my cock and started jerking me off. It didn’t take long before I started cuming. She was so into making me cum, she was going faster and faster. The more she pumped the more I kept shooting. I felt like I was never going to stop. When she finally had my balls emptied, I looked up and she was covered in my cum. It was all over her belly and tits. She leg go of my cock and with both hands, smeared it all over herself, she was playing with my cum.
I said, “Oh shit, I never jerked myself better than that.”
She said, “if you think cuming from a hand job is good, wait until a pussy makes you cum, it’s magical.” Then without saying anything she claimed off me, went into the bathroom. I assumed it was to clean herself off. She came out a few minutes later and said, “Awww, look how soft he is, poor little guy. But I’m willing to bet, I’m gonna see him at attention again tonight.”
I asked, “What makes you think that?” She walked over to the chair and bent over the arm. She reached underneath herself and started playing with her clit.
She turned her head and said, “Because my pussy is wide open right now, and rubbing my clit just isn’t going to be enough.” Then she squatted down a little. I could feel myself already starting to get hard again as I walked over to the chair. She turned around again and said, “you won’t get a better invitation than this tonight, so you better get hard quick before I make myself cum again and change my mind. Seconds later I was rock hard again. That’s when I really got to know my older sister.
