We are sitting on hard wooden chairs that are on a ceramic tiled floor– an important detail for later. In front of us, on the table, are several pin... tumblers full of ice-cold water. We are about to start a competition neither of us is sure about who might “win”. Is win even the right word?The competition – the first one to have to give in and pee, the toilet down the hall being out of bounds! The loser will have an accident in their pants, sat there in the kitchen. The “prize” for the winner. “Will either of them stop the tractor?” I had to know this because I was about to drive a tractor for the first time in my life and it was still parked on a railroad flatcar. When I looked down at the ground, it looked like I was on top of a mountain.“Si,” he told me and nodded.“Now set the spark like I showed you.”“Here?” I asked as I moved the lever.“Si, you learn fast. Now make sure the gear stick is out of gear.”“You didn’t show me that part. What do I do now?”“This stick in the middle,. ” She moved near the foot of the bed and began sliding the panties up my legs. “I picked some extra silky ones. Because I know how much the silky texture will tease your cock throughout the day. Plus, it’ll make a good reminder of how badly you want to get into MY panties.” The panties were much too small to contain my swollen cock, so my hard shaft had no choice but to jut out the top of the panties and stretch the fabric to its limits. “They look good on you” Susan chuckled. “How do they. Dad took just a couple minutes to recover then we went at it again all evening and into the night. He fingered and tongued my cunt as I jerked his big cock. My dad could cum over and over and he never got tired of eating my pussy as I hand stroked his cock. He stayed hard for hours. After a few weeks he then taught me to suck his cock. I was not sure I could get that big membetr in my mouth but I did. He felt so smooth against my tongue and dad showed me how to suck him and take him deep as I.
