I realized he seemed a little nervous going, but we didn't really talk about it then. Dad went in and they needed him to update some of his history an... insurance information, so he did that while waiting. Then the nurse came out and called him back. He handed her the clipboard that he had been using and she told him to wait for her at the scales while he handed it to the one that need it. She weighed Dad. (179 pounds) and asked his height (5 feet 9 inches). Then she told him to take a seat in. I was terrified and completely excited. I'm about five feet tall and this monster was a foot long and thick like a potato chip can. If it got all the way inside me it would be wayyyyy up there. I wondered if it was even possible. That first time he got maybe six inches in me and I was cumming wave after wave. I must have been sexy to him because he started fucking me and making it even better. The only sounds were my moans and the sounds made when a girl bounces on her lover's cock. Well. I wanted him to see more though. I took hold of her hair and kissed her deeply. Intimacy I thought, give me it while he watches! She remained knelt before me and I forced a finger inside her. She was wet and her pussy gripped me. I was rough, finger fucked her hard. Her body tightened, I slapped her face and kissed her deeper.“Cum for me bitch, cum!”I slapped her again and her convulsions began, writhing on my hand. Still gripping her hair… I felt him watching.“That was hot, not sure about. Never forget it bitch!!!" Yewwss Pwwinccessst Hhaannda." She slowly took one foot out of my mouth. Spit huge in the air, i caught it like a dog catching a bone. "Good bitch. Bark for me." "WOOF!" She laughed "No you stupid little doggy. No..No.. You are a little pussy dog. Small and useless. Come on sweety. Barkie, warkie." I got on all four close to the floor. I saw my spit with a tiny bit of toe jam in it, I lapped it up arf..arf.. All but silent."Good bitch.. Fetch!" Smoething flew across.
