I can see the relaxation slowly creeping over you as it seems you sink deeper into the bed. The sound of my hands rubbing again, more oil to warm, mor... of your body to touch. I roll the top edge of the towel back, just to where I can see the separation of your buttocks begin. The movement sends a small shudder through you. With my palms facing out I begin to stroke the length of your back up towards your neck, my thumbs rolling the muscles they find in their journey up, my finger tips brushing. So, I got back on top of the bed and started stroking again. They were amazed that I was right there next to them and jerking off. When I finally came, I squirted on my oldest sisters leg and they both said 'ewww' and started laughing again. After they left, I jerked off two more times I was so excited. I peep at my mom and both sisters whenever I can, so I have seen them all naked before, but they don't know that. My mom is 39, divorced for 5 years, has a great job that keeps her busy a. Your body shudders and you pull me closer still. My free hand caresses your back and I feel your skin above the fabric of your night gown. The strap is loosely hanging off your shoulder and my hand travels down your sides. Skin, fabric, skin. I love your skin. Yet there is a strange excitement in caressing you where your skin is out of reach. Beneath the silk. My hand travels down your side. I can feel the softness at the side of your breast. I want more. Through the silken sheath, my hand. “Why ... how do you know?” I asked her.She didn’t answer for a moment, then she meekly responded with “I’ve had a big fake cock in me. So I know that your cock will fit”.Now there is a story that I will need to explore ... later.With my cock poised at the entrance to her tight canal, I pushed firmly against the tightness. It probably took 10 to 15 seconds of constant pressure before I felt my cockhead slowly enter.“Fuck that’s tight ... insanely tight” I commented.“Keep going ... keep going”.
