After my first set I just lay there and Julie never moved. I was getting ready for my next set and imagining what her pussy looked like under that spa...dex. Julie said, "hang on a sec I'm sweating like a pig." She reached down and with one swift movement grabbed the bottom of her sweatshirt and pulled it over her head. I looked in amazement at her matching white spandex sports bra. This also didn't help the problem in my shorts one bit. I don't know how I did it but I managed to get through two. I had to really hold on to her to keep her from sliding off my lap but I continued to paddle her until my hand really started to feel it as much as her behind. I stopped for a minute and rubbed her cheeks which made her moan a little. She was the most beautiful shade of red that I have ever seen, it was like her butt was made to be spanked this way. I told her she could get up so we could take the pictures for her husband.She wiped a couple of tears from her face when she stood up and got her. As he starred at her, she stared back and said, “Baby, I can’t wait any longer – I need you now.” That begging nearly undid him, but he remembered his promise of paybacks – he took his hard cock in his hand and used it to gently rub her pussy and said, “Tell me what you want?"And she responded, “I want you to fuck me with your hard cock.” “Not good enough, I want you to beg for it.” “God, please, baby – I need you to fuck me now… I need that hard cock inside me…please.” He couldn’t hold out any. I had flashbacks of my own days of welt's raising up on my back—b l e e d I n g. I grab dad by the arm, and beg “dad---dad--chill. You let him worked you up dad—lemme handle Dustin”. It took a few moments for dad to calm down, but I guess he decided it was best not to start hitting on lil bro the way he had done me at that age. I was quit a bit older now, and bigger, and would not have been afraid to go one on one with the ole man to protect my lil bro. I didn't have much to do with him these.
