MEI-017 - Secret incest gameplay: Sister and brother earn tuition money while their mom watches through a magic mirror

A single-mother household edition of Prestige's popular 'Behind the Magic Mirror...' series. It's a variety show concept that offers financially struggling single-parent families a chance to win a large cash prize. On the 'surface,' it's a modest challenge where the single mother takes a middle school entrance exam (passing with 70+ points), but that's just a ruse. While Mom is busy thinking, the sister and younger brother are called into a 'separate room (behind the magic mirror)' and coerced into 'sex (incest)' with a large sum of money as bait. While 'touching breasts' or 'grabbing his junk' might be excused as an 'extension of play,' they eventually lose control while rubbing their genitals together. At the sister's suggestion, she guides his erect penis into her wet pussy. While Tsubasa Hinagiku, Kuran Ito, and Yua Nanami appear as the sisters, the aura of popular solo actress Tsubasa is clearly on another level.
