[Vulcan Nure] My Aunt Is Very Naughty {desudesu}

When young Yuuta-kun's clumsy attempt to help his glasses-wearing aunt Satsuki-san lift a heavy chair goes wrong, an accidental spill triggers a wild body swap between the two. Suddenly trapped in each other's voluptuous MILF figure with its large breasts and sensitive nipples, the embarrassed aunt and her shocked nephew must navigate the switch with plenty of spankings, teasing, and steamy explorations of their new bodies. What started as a simple household mishap turns into a deeply forbidden bonding, with Yuuta gleefully declaring "third proof" of his new dream reality before a hasty return swap leaves them panting for more.
