My son Yuta returned home after a long time for his friend's wedding. It had been two years since his father remarried, and during that time, not only did his stepmother (Hinano) move in with her mother (Fumino), but also his stepsister (Non)! The awkward atmosphere was palpable as they all gathered at their new family home. Despite this, Yuta couldn't help but feel intrigued by these beautiful women around him. As he tried to maintain secrecy from his father, one thing led to another, and before he knew it, he found himself engaged in a wild threesome/foursome orgy with his stepmother and stepsister! Keep in mind that depending on the distribution method, some scenes may vary or be omitted.
