My son has this girl Bisi he has been dating for a year now and they have become close that she now calls me daddy. I dash her money too from time to time with no agenda or thoughts. So one time my son travelled she came to the house and stayed till late, and we talked late into the night. I found out she liked me , she said so. That I’m generous and kind. She excused herself to go shower and came out wearing nightie with nipples sticking out. Very inappropriate but I did not wander, kept it civil. But on second thought I asked her if she could give me a massage and she happily agreed. She told me to lie on my stomach and she sat on my thighs and started. Her skin was so soft, I found myself thinking how to calm down but I was aroused. When she asked me to turn around I she discovered my hardness. Without prompt she put her hand in my pajama and pulled it out. She was surprised and said wow it was even bigger than my son’s. I took her from behind without protection…now I fuck her regularly and my son has no idea.
