"Mom," I hissed!"What the hell?" I asked her about my sister."She's in her room," my mom said."But --" Don't worry about it," said Mom. "She's talking... on the phone." She could hang up," I scolded her."You know how she is, Tony." Mom sat on the counter-top. "I just wanted to talk a bit before you left for work." To be honest, Mom," I said, beginning to stroke myself to erection, "I'm not much into talking right now."She grinned and her face looked even more lusty and lewd. "Then I haven't missed. During first few days it was just good morning and some general talks and a good night on WhatsApp. After 4 days she had put a status how men are unfaithful and cheaters, so I asked her what happened, she said cryingly her husband has an affair and she cannot do anything about it.And said she has to take revenge and confessed that she like me and like to have sex with me, I was shocked and was feeling happy at the same time.Then the next day I called her to my home as my parents were gone for. After a few minutes of just relaxing, her thoughts began to wonder. At first she thought about the usual things; school, ughh,family, what she was going to do with the rest of the weekend, and finally her friends, or more like one in particular - her best friend, Crystal. She thought about Crystal's stunning smile that could cause a whole room to smile with her. She thought about her mesmerising blue eyes that like her name were a crystal blue. She thought about her long blonde hair that flowed. At that night we have a hard sex and sounds of my girl friend comes very loud, i thought may be Vivian may heard heard the voice of her Mum but due to our high fever i let it.And the next morning at break fast Vivian was smiling at me as her Mum is in kitchen and i asked Vivian why u smiling at me and she said nothing, i ask to her that did u felt good sleep last nigh and she said yeah but late night and i ask did u heard some voice last night and she replied nothing just smiling, and i came to.
