Jets of hot juicy sperm hit my tongue and the back of my throat. I swallowed and kept swallowing and sucking until he‘d pumped out all his load. My ...wn lust and swelling of my cock was painful and it demanded attention. I stood up and grabbed my dick and started jerking rapidly. He took my face in his hands and kissed me deeply and deliciously. He bent down, got on his knees and took my rigid cock in his mouth. Mmmmm, it was so warm and wet and glorious in there. His tongue and lips and mouth. I then told Her about being married and how We were swinging separately and both enjoying the experience (often coming home and talking about Our encounters ,Hers meeting with couples with Bi-wives and Lesbian females ....During this time She had excused Herself to go to the restroom and upon sitting down She stated wasn't in an aroused mood particularly but,after the conversation turned towards the sexual habits of our respective selves She said She found Herself very wet ...She then said that. ”　She came up with the wonderful line;“An expensive nanny is a hell of a lot cheaper than a divorce”The more they talked the more sense it made to Jane. Of course as they both acknowledged it may be difficult to pull off; but one night when Jane was going through a phase of doubts about it all, she showed her mother some photos David had taken of himself and stored on his lap top. He was sitting on the floor of their lounge with a dolly, short little girl dress showing off his nappy and plastic. I was in heaven my sister’s mouth was so small, soft and warm. Finally, I cummed in her mouth she did not understand what was happening. I told to swallow but she couldn’t make it. All of my cum was flowing on her dress. I heard some gate noise I think they are our parents so I told my sister to go to the bedroom. She went her room and changed her clothes. We acted as if nothing happened.After that incident, we started to fool around like kissing without anyone noticing touching each other.
