The fact we were brother and sister was forgotten and our relationship became more amorous each day.We wanted more than anything to be married. I know...it sounds insane but to us, it was a normal progression to our ultimate objective. Sometime around the third month of our affair, we decided we would leave the valley. It wasn't a choice really, it was mandated in order to raise our children and make a life for ourselves.Our plans were on hold as long as mom was alive. Neither one of us wanted to. It was so good. My pussy clenched. I struggled so hard not to erupt into her mouth. I had to be strong. I had to exorcise the demon. My hips shook, my arms moved, my feet shuffling in place. I couldn’t do the whirls and twirls of the Kagura with the woman’s sucking mouth locked on my dick.But I could still dance.Power flooded out of me. It rushed through the room. Light blazed as my lips moved. I cried out the nineteen names of Yokubo-no-Tako, I recited the glories of my ancestor, the names of. As the head popped in it was better, and as she began to slowly ease if farther in, the discomfort became significant and I asked her to stop. She said it was barely past the head, and that if big boy didn't get into her any further than that he'd be pretty sad. I told her to work it back and forth a little and it did deepen slightly before it became too uncomfortable. So we quit. My erection had vanished by that time, but when she said, "OK, it's your turn," with a smile and a wink, it came. It should have felt wrong but it didn't. Instead it just felt amazing. Ever since that evening our relationship with one another had become much more sexual. These passionate kisses had become our regular greeting and happened quite frequently. Despite the quantity, the quality had not declined in the slightest. Sex also had become a regular between us and was often spontaneous. Whether we were watching TV, eating dinner or even driving, whenever one of us had an urge, the other was glad to.
