Spontaneous fantasy fulfillment.
Linda and I had been next-door neighbors and were friendly while she was in the process of a divorce and my wife and I were going through some difficult times. Years went by, now I was divorced, and was so surprised to see her when I walked into the party. She and I talked during the evening and I walked her to her car when she was ready to leave. She told me she was so happy to see me again after so long and suggested we keep in touch.
While handing her business card to me, she wrote her home phone number on the back while saying "call me anytime". She had remarried and when I reminded her of that, she said she and her husband were living like housemates and sleeping in separate rooms. Soon we had a great afternoon at her house when everyone else was gone, taking our time and exploring our wants and needs. She loved it when I slipped a finger into her snug pussy, then two, and she couldn't get enough of stroking my hard cock.
The first time she came to my place my daughter was out for the day. As we walked back to my bedroom, she looked into my daughter's room and asked about her. A light went on in my head. My daughter had been reading vampire stories and had showed me a passage about a father and daughter having sex together. After feigning shock and surprise, I had gone into the shower and jerked off, imagining sex with my teen-aged daughter.
I told Linda I had a fantasy and would she be interested in fulfilling it with me. She was game, so we entered my daughter's bedroom and I reached into her closet, presenting Linda with a knit dress just a bit too small for her. "I want to fuck you in my daughter's bed while you wear this". Her eyes lit up as she changed into the dress with nothing else. I laid her down and began gently rubbing her pussy, then licking it while I massaged her tits. I was hard in no time, and shrugged off my pants and underwear. Kneeling between her legs I put her hand on my cock, saying "stroke daddy's cock, honey". Linda smiled and began a slow, sensual motion. She rubbed the head between her moist pussy lips, and then quickened her pace, much to my delight. I had a wonderful, magical cum spurting on her fine pussy hairs.
