"The following morning, I got my 'charity fuck' out of the way early, to be reasonably fresh for the cash customer that evening. Then did my day's wor..., and headed home, pleasantly intrigued by the mystery client.Just before seven, the telephone rang."Mrs Smith will be at the door in five minutes," a male voice said. "Please be ready to let her in immediately."Five minutes later, I was standing by the door as a car pulled into the drive. Two people emerged and came straight in. The car swiftly. Let me startOn a vacation my #aunty and her #daughter came to our place .One day early morning I was in sleep I could feel somethings different and when I slightly opened my eyes I saw my younger sister (my moms sisters daughter) she was only 13 meanwhile I was 17 ! I slowly took advantage and She was trying to lock my lips ! Where I kept silent !Then she gave many liplocks but I didn’t respond to them ! We woke up day went smooth ! So the same night we were in the same bed ! Next to me and she. Then I lubed a finger along her pussy before sinking it into her wet hole and finding her clit with my tongue making her shudder and whimper. She dropped back to my cock, sucking the head and caressing my balls. After a few minutes of steady rhythm on her clit I quickened my tongue and she let go of my cock again, moaning loudly. ‘Oh… Mark, I’m cumming!’ and her body shook as it did last night and she let out a soft scream of pleasure. In hindsight, my ex, Tina, definitely used to fake her. I could see my grandfather watching me from the shore. I figured he knew what I was doing but I was sure that he couldn't actually see my nakedness.After getting all of the sand out, I slipped my suit back on and went back to the shore. I was puzzled by the look he was giving me, not that it scared me. I was just puzzled. I wondered if he was thinking of me in a sexual way or was he even able to have sex. I had very limited knowledge of older people. I, erroneously, thought that after maybe.
