Loading the car with what I taught was required for a fairly straight forward job I headed on the 10 minute drive to her house. Pulling into her drive...I could see her walk around the side of the house in a nice summer dress, a little see through as the sun light caught it as she walked towards me. “Fair play to you” she said as I got out of the car. “The new one is in the garage” “not to worry, I’ll manage better get the old one out first” I replied. It was going to be straight forward, pull. I open my locker, and, big surprise, there are my keys."Come here, you fuckers," I mutter to myself, and I step out of the locker room.As I walk to the door, I realize that the room isn't completely empty. Laying over one of the chairs is a pair of clothes. I walk up and look at the clothing: a nice pair of short shorts, a shirt... socks... shoes... underwear? Why is there a bra here? I thought as I looked at the clothes. I look around the room and see nobody is here. Well, shit.I make my way. I scampered off to my room after shouting hello to my mum who was in her bedroom getting ready. Hair dryer going. She said that she was going into work and would see me later on. I got into my room and realized that I was still in my mums panties. I stepped out of them and thought I had better put them back into the wash in case she missed them. I opened the door and ran over to the bathroom naked and went inside. With my mums knickers in hand I was in the bathroom naked and to my surprise. Each thrust sent shock waves of rippling lust through her body. Nothing had ever felt so good as having her pussy stretched and pounded by her big-cocked sister. She closed her eyes and groaned, delighting in every pulse and flex. Then she felt Diana’s hand guide her still-solid cock from underneath her belly. She bent it downwards and shoved it between her legs.“OH MY GOD, DI!” Maddi sat up as her own cock head kissed the opening up Diana’s pussy. They locked eyes in a quivering moment of.
