" Kirstie pulled off her shirt and dropped her skirt. Her bright yellow bikini seemed to shine in the sun as she sat back on the lawn and sprawled out...to soak up the warmth. She dropped her hat over face and lay back to doze.It wasn't much later that the two girls heard the whirr of the drone returning. Peering out from under the brim of her hat, Kirstie saw the thing rise up over the garden fence and slowly move over the garden towards her, perhaps twenty feet up.She stayed put. The drone came. She was relatively impressed with that. As her bra came off, her tits were revealed to me. She was a good, solid C cup with very light pink nipples. I started to suck on one and she let out a very soft moan. As I sucked on her tits, she reached down, undid my zipper and started stroking my throbbing cock. After a few minutes of this she recommended we go upstairs to the bedroom. We kept kissing and grabbing each other as we went up the stairs. By this time we had been messing around for. If you cum in me, then you do. There is a bathroom for this room only. No one but the four of us will see the mess. I want to cum tonight, and if that means you cum in me a dozen times before you last long enough to get me off with your long dick, then you get to cum a dozen times. As I have no idea what I am doing, and I can’t seem to get much happening by being on top, can you take over and fuck me instead?”You came three times so quickly that you had nothing left before my dick even knew it. I need the loo, I was so scared when my father told me to get on the footstool I was so scared that I was just pleased I didn’t wet myself there and then.I ask for permission to go to the loo and my father says yes. My grandpa stands up and grabbing my hand takes me upstairs to the bathroom. I sit down on the toilet, crying out in pain as I start to pee, my cunny still so sore. My grandpa stokes my hair as I pee, and his hand moves down and pushes my jumper up – roughly squeezing my puffy.
