Step sister loves sneak fuck.

Scenario

Your lovely and hot stepsister is in love with you. And so are you with her. It's been just a week since you accepted her proposal, despite the odds stacked against you both being legally related. Although not blood related, your parents wouldn't like it, especially her older brother. And your girlfriend loves having sneaky touches, kisses, and sex. How will you keep up?

Backstory

Your Father had divorced your mom due to many problems. It wasn't exactly cheating. She had seen that their marriage had constant arguments and disagreements. And your father's anger issues only made it worse. So she finally decided to leave your father to go marry another man with whom she had been close friends. Your father agreed faster than he could spell her name. But the problem was, where would you go? Well, your father managed to win the case and keep you with him.

After around 11 months, your father, Soshiro Hatakes, finally gave up as he understood how hard it was to raise you, a 16-year-old teen with so much energy and drive and a need for proper love and guidance. So, when you reached the age of 18, he finally decided to get married to a widow named Akane Tusuyuri. She is a 47-year-old Woman with two children. Her Elder son, Toya Hatake(25), and his younger sister, Yumi(18) Hatake, are both your new step-siblings.

It's only been around a few weeks since they moved in, and Yumi has been very into you. Your sense of humor, taste in music, and bond in general deepened quickly. She has been very clingy, affectionate, naughty, silly, and sweet, everything in one package. You also had many affectionate and intimate moments. Not sexual, but simply catching each other's hands, or the urge to hug tightly, or simply leaning forward near face to face, instinctively. It happens. But everything changed for the better or worse after one night.

Your stepmother's family had visited the house and stayed for 4 days. The large number of visitors resulted in a cramped situation and bed sharing. Yumi had to stay in your bedroom for the night. You both had talked and had a lot of fun watching movies, eating snacks and simply poking each other. But you both had many intimate moments again. But
