”A flush of shame caused me to shiver, but I told her straight, “I’m sorry sweetheart, I have a stiff penis and it’s rubbing on you.”Pepper ...ad been at my parent’s ranch many times and was aware of how animals mated, how the bulls, dogs, horses, or other animals got aroused and mounted the female; she understood a stiff penis. She thought about what I said then offered, “It annoys me, can you move it so I can drive better? Can put it under my butt?”Uh! Just the idea sent a thrill up my back,. I explained to her I was into self bondage and had done this myself but could not get my left arm tied up just right. She asked where the keys were. I told her I left them in the car in my purse. She got them and returned with the keys. Then she did something that surprised me. It took me so by surprise, I didn’t even have time to react. She undid my left arm and very quickly retied it back up properly. Now I was at the mercy of a fifteen year old. I was a little worried and at the same time. "Simon I suppose you are wondering why I have kept you here?" All I could think about was the stories of her fucking boys as I replied, "Yes miss." She laughed and said, "I bet you have heard the stories about me? Well they are true! I have been thinking about you since you came into my class." She looked at me and continued, "You are such a big boy and I was wondering if you are hung to match. Can I see?" Some would see this request as being wrong from a mature woman to a 16 year old, but I. He can’t believe his luck. They both look to the front at the same time to see if the elderly woman has noticed anything. She’s facing the front, oblivious to what’s happening two rows behind. Samantha looks back at Johnny's face and with a sexy smile begins to ride him harder and faster. Johnny moans into her chest and clutches her ass as she fucks him senseless. “Oh fuck, Samantha, oh fuck!” He repeatedly gasps as she picks up speed. Thirty seconds pass and suddenly Samantha’s movements start.
