One day we went to shopping at spencers. There I saw a woman with huge breasts each in the size of a coconut. I was continuously staring at her and my...aunt caught me and gave a worry smile. After completing shopping we headed home. I was silent as I was embarrassed and my aunt suddenly broke the ice and said what were you staring at the mall. My jaw dropped and I was stammering to answer and suddenly she told so you like big boobs.. The word boobs my aunts mouth kept me tongue tied after few. It was the meter reader man from the electric company. He was tall and black, with huge muscles. I would have guessed him to be in his forties.At first he didn't see us laying there. He walked over to the electric meter to take his reading. I looked over at Sarah, she had an evil grin on her face. She turned to me and whispered in my ear, "Lets give this guy a show, it'll be fun." We then dropped our towels, exposing our tits. I couldn't believe what I was doing, it felt so naughty. When he saw. He grunted several times and suddenly his cum was everywhere. With no other choice, I began to swallow. In Adam's case it was more like drinking. His cum was like liquid fire in my raw and sore throat. I began to gag and Cindy warned me that if I lost even a drop, I'd be really really sorry. Adam continued to cum over and over and over. I could feel it on my tongue moving up through his cock before it exploded in my mouth. I was crying then while trying to suck and breathe and swallow all at. I remind her that she lost the last bet and she has to do what i want, but she refuses, I go into my bedroom and get my hand cuffs these are police issue she wont get out of these unit i let her. I ask her one more time to honor her bet but she refuses again, i tell her it ok you will one way or another she asks what does that mean. i tell her she can do it on her own or i will make her and it ok with me either way. walking at her she now sees the cuffs which she knows means she going to have.
