I sold my soul to Satan when God didn't hear my call. At the tender age of 12, the lonliness slowly crept in. By the time I was 13, and my pleading and prayers went unanswered, I turned away from God and begged and pleaded and prayed to Satan. I offered up my soul, knowing full well the cost. I told him that my soul was in his hands, and his to take, completely. Soon after that night, a few nights past. My sister came into my bed. She wanted cuddles, she's scared, she said. We spend each night, night after night, I holding her, she held me tight. Soon she felt my hard cock through my pants, and then one night, she took it into her hand. From that night on, our passion grew, she'd pleasure me,  I'd lick and drool. I rubbed my cock along her slit, she loved her brother against her clit. I'd spill my seed all over her quim, she'd take her hand and rub it in, around her clit and into her hole, she'd take my seed and lose control. We were careless, but she never conceived, sisters egg and brothers seed. For many years, she was the one, until we grew up and had to leave home. We never really talked about it again, but I still know the cost for the ultimate sin.
I freely gave my eternity way. I know when I die, I know I will pay. So, until this time, I will push through my life. Nihilism, depravity, depression and strife. But I still seek that feeling, that I felt with her. The taboo of incest, the ecstasy blur. The feeling that what you are doing is wrong, the succubus call, deep dark hell's siren song. And soon I will die and my soul will be bound, taken by Satan when he comes around. Eternal torture, pain and strife: all for my sister, I gave her my life.
