Although it was Helen who had opened the door, she wasn't the one that starred in Katie's masturbatory fantasies, no that honour belonged to Lucia, Ka...ie's mom. The first time it had happened Katie had been disgusted with herself, but the strength of the orgasm had burned her mom deep into her sexual psyche, and, over time, Lucia had eclipsed all others in her desires. Oh she had flings, but never serious ones and her mom came between her and her lovers in a way that would probably have shocked. It had been a long tiring week and it sounded like a very good opportunity to blow off some steam. We must have stopped a five or six bars, playing shuffleboard and having drinks at each place. Finally around 2:00 am we headed back to his house. Well, actually his mother's house as he lived in the basement and had his own entrance. My home was another 20 mile drive and he suggested I sleep in his couch rather than drive any more. I agreed and we found ourselves having another beer and watching. I was doing this in the bathroom. little did i know that he was wanking over these into my underwear that was drying. He left sharply but i only found out when i put them on and my pussy was covered in sticky old man cum. couldnt believe it!! I went round to give him a telling but whilst waiting on my panties getting cleaned (i wouldnt do it) and a few more drinks he started to touch my leg then put his hand up my skirt touching my pussy over the other panties i had to put on. i tried to stop. We talked about the courses we were taking and our plans for the future. While I had thought long and hard about what curriculum I wanted to pursue, she had basically allowed her husband and counselor decide for her. She had no idea what she wanted to do with the degree she was working on. Before we knew it, it was time to go to our next class. We walked together and continued our conversation. When we reached class Susan sat next to me. From then on it just became a pattern. We were officially.
