Since my mother remarried, every day is bright, fun, and fulfilling. Except for one thing... I never thought it would turn out like this... Five years ago, my stepfather demanded my body, and I couldn't refuse and allowed it. I can't tell my mother... If it's discovered and the family collapses... From then on, my father's persistent sexual release. If I can endure that, it's my ideal family. Even when we went to a hot spring as a family for my graduation trip, I stole glances from my mother and while she was sleeping in the bath or room, I was given a sticky cunnilingus and inserted freely. Sadly, my stepfather's hated dick gradually became familiar with my vagina and now fits perfectly. The compatibility of our bodies is so good that I climax unwillingly many times. I act bravely with a smile in front of my mother, but secretly I'm a bad me, a meat onahole dedicated to the old man. I shouldn't feel, I shouldn't feel, it's a trip for me... The worst immoral climax. Mom, I'm sorry for being such a lewd daughter.
