I normally sleep in the nude but I put on a shirt and shorts for the night. I got onto the bed but I couldn't drop off. I guess I was thinking about A...by. I finally couldn't take it so I got up and went to check on my sister. I knocked gently on the door but my sister didn't answer. I opened the door and looked in. It was hard to see but I thought my sister was asleep.I walked in a few steps and I heard my sister's voice."Tom, is that you?"I told her I was just checking up on her. She told me. .. well, I mean ... you're in your room. On your bed. You're naked. I'm ... I'm watching you ... you're ... well, it isn't real, it really doesn't matter ... And I know it's wrong to think this, it would be wrong to spy on you ... " Tell me. Please? I really want to know. It's OK. It's a fantasy. We all have them. I'm not upset you would spy on me. It turns me on to think you want to see me that much ... " You're playing, masturbating ... That's it. I watch you." Does the thought of that really. I got her close but I didn't let her go over the edge. She grumbled with frustration when I pulled away. She stopped grumbling when I slipped my cock into her.Mom was wet and warm and inviting. My cock filled her with ease. Still, her inner muscles were strong and they squeezed me as I hit bottom. For a moment I was held tight as my mother teased me back with her pussy. Then she let me go and I started fucking her. Like she'd asked, I kept my strokes long and slow and it drove her wild."That's. But went for it and shoved the entire nine inch dick into her mouth. She sucked it up and down" Oh yeah Brooke! Suck it hard." Raul moaned loud."What is going on in here?" They both heard Lily's voice ask.They both scrambled to get up off the bed. "God Lily I'm sorry...." Raul stuttered.Lily walked over to Raul from the door way of the room. "I know. And I knew this was going to happen. I just didn't think it would be this long." She said puling his face in both of her hands. She kissed his.
