It started out as a normal night out. I thought the usual, she would drink two or three glasses of wine and sleep, when we get back home. So we went out as normal and she drank her three glasses of wine and when we came back to the house she fell asleep on the sofa. I looked across at her with her shirt dress on and black stockings she looked so horny. The lights were low and the house empty. I knelt down beside her and touched her leg, softly, she did not move. I touched it again, a little longer this time, her breathing stayed the same. I touched her knickers rubbing ever so softly, still no movement. All this must have taken about 10min and although nervous I now had a rock hard cock. Pulling her knickers to one side I inserted a finger into her wet hole. Carefully working it in further and further and ever so harder, as I was now so turned on, I did not care if she woke up. She awoke quite quickly and surprised me and asked what I was doing but realising, she opened her legs, I could not get it in fast enough. She called me a few names but she kept saying, I love your big cock, just give it to me.
