We were both impossibly aroused—that much was obvious from my unwavering erection and the big, prominent nipples denting her miniscule shirt. But I ...asn’t sure if Elizabeth still considered me “off-limits” because of her friendship with Stephanie. The whole day, from those awful bee stings to this very moment, Liz had been acting much more openly affectionate with me than she had in weeks. Maybe she had changed her mind. God knows, I wanted her. I couldn’t take my eyes off her hot, luscious. I knew instantly I couldn't have sex with my mom. I loved my dad and would never do anything that would ever hurt him. My cock shrank as the excitement I first felt at the thought of fucking mom shifted to anger at the thought that she would betray dad. Once they were done cutting the cake, I watched mom feed dad before heading to the secret rendezvous with mom and Lilly, hoping Lilly would be there. I quickly texted her for confirmation she was coming, hoping if temptation got too hard to. I asked whether or not I could cover up or something, but she told me that that was out of the question. Sure enough, I walked the room twice, and figured my ordeal was over. Far from it. She tells me to lie on my back on the table, spread my legs, and bend my knees. That is when she checked me for a hernia, while applying a good amount of pressure. Not to mention, she had long nails. She did one side at a time, asking me to turn my head and cough. She made me cough 3 times for one side, always. During this time I stole the spare keys to their house from my uncle. Once inside I jammed the locks in the main bedroom and made the side door to house look like it was locked(it was….but from the outside to enter at my will).In the evening the couple returned alone the brother having returned to his own house 200 kilometres away by train(I knew he would leave).At around 8’o clock my family went to sleep. My uncle, due to his habit as a security was not used to sleep at night so he always took.
