"You're kidding right," she said and moved off.It was very late before everybody had gone and the mess was cleared away."We're off to bed now," said m... mum, "no point getting up too early."Our parents had converted the attic of our single story house into rooms for my sister and myself. Two bedrooms with a bathroom in between that we shared. I just got into to bed when the door to the bathroom opened and my sister came in and sat beside me on the bed."Have a nice time?" I asked.Mmm, lovely. She went to her husband and started drying her husband. As I dried myself, I couldn’t help but notice how revealing her thighs are now. I kept peeking at her body. Her thighs are too meaty and kept shaking as she dried her husband.As she walked away, she smiled at me. But an unusual thing happened. As she walked past me, I saw her smell her hand, the one I shook hands with. I couldn’t believe what happened. Did she smell my cum that day? Did she like me staying around? Or was she hinting a. ..

Every time she pushed me to new heights of excitement. My cock was throbbing under all the nylon, and I was sure I was going to explode. But somehow every time. My cock was super hard! He had me lift up my legs bent at the knees, then he pulled my panties around my ankles and spread my knees wide apart, making my panties stretch between my ankles. I was totally and shamefully exposed to him!He then said “Stay right there Andy, I have to run out to my car and get my good camera”.“Ok daddy”He walked out of the house. I was laying there with a hardon kind of stunned, acknowledging to myself that this was really happening!I herd him walk back in the front.
