‘It’s okay,’ he said, ‘I had the same reaction at first, but all you need do is breathe through your nose.’ I looked up at him and nodded, t...e tip of his erect cock still between my lips. ‘You have masturbated,’ he asked. I nodded. ‘This will be much like that,’ he said, ‘imagine that your mouth is the hand on your cock. You will go back and forth until I ejaculate.’ I nodded, trying not to let his cock escape from my mouth. As I did so I felt my cock grow hard and my asshole begin to tingle.. " Thank you Thelma, you are such a help. I know that talking to you inthe future will help me in the decision." With that I hugged hergoodbye and told dad that she wanted to speak to him. I picked up theSeventeen magazines and finished reading it while I waited for dad. Whenhe returned he sat next to me and patted me on the shoulder. "You sure you want this?" he said smiling."More than anything dad, it's who I am, and who I'm going to be." Ok, I just wanted to be sure you were sure about. If I'd begged, would you have let me off?"I really thought about it. "Probably."I thought some more."Would you have begged?" Probably not. Are you going to?"Another long silence."No."She grinned then quickly kissed me on the lips."Pants off then! Let's get this bet settled."Easy to grin for some I thought and unbuckled my belt. My trousers dropped to the ground. The afternoon sun was warm on my bare skin."And the rest." She said."Susan, come on..." Drop 'em!"I slid my underpants down. I was. The pictures and videos just make my cock so hard. Seeing her bending down and wiping the floor, while her breasts are just moving here and there inside. Plus, when she turns around and bends down, I would be so tempted to just live up that dress, pull down her underwear and just fuck her from behind.But I try and control myself and slowly rub my hard erect cock when she is in those positions. Her lips are kinda juicy and fat. And they make me go wild. Every time I see her, it’s like I wanna.
