#383665 - We staid in that position for sometime my pre-cum dribbled down her neck, Tina told me to stop and went to the bathroom leaving me kneeling on the bed, l assumed she had gone to remove her sanitary towel but my sister came back holding a tube of what l thought was toothpaste, Tina gave me the tube and declared that she brought it from the chemist before we left home because she knew that we had to try it one day then climbed onto the bed, got on all fours and spread her bum cheeks. I had been out for a Friday night drink with mates and bumped into my elder sister Tina with her friends when the evening came to an end, l jumped in a cab with Tina to share the fare, she had moved back home after splitting with her husband.
