After 5 days she called me and was talking and within 2 mins without any reason, she told me she is home alone as everyone has gone out and won’t be...home till evening. I knew this was my chance and asked her if I can come over. She said yes that’s what she was hoping, she also told me not to ring the bell but to just open the door and come inside as she didn’t want the neighbours to be alerted.I went to her place and opened the door and went in, I slowly locked the door from inside. I turned. The door on their side of the bathroom had been left ajar, and my curiosity got the best of me. I snuck in and peered into their bedroom. My sister had always been afraid of the dark, and just as she always did, she left the lamp on by the bed.

She was looking down at him as he was obviously bringing her to orgasm with.

Her Maker must have had me in mind when they were molded to perfection.I bent my head and let the tip of my tongue run a small circle around the base of her nipple, then wiggled it. Her nipple obviously enjoyed the treatment; it stiffened a little more, hardening against my tongue.I could feel her chest heaving as she took a few deeper breaths. Her excitement started to build. I did not want to hurry her and broke the contact. Her hand came up immediately to push my head and mouth back to her.
