Introducing a new series of onee shota projects! Maseo-kun comes to visit his relatives' busty sisters during winter break. At first, he's a precocious brat who puts on a demure face. He gets very excited by the busty sisters Yuu and Walnut. The older sister Yuu has a bust size of 110 (J cup) and the younger sister Walnut has a bust size of 98 (I cup), making them an incredible pair! Maseo can't help wanting to see the two naked, so he plays all sorts of pranks on the busty sisters while looking over at Kazuya, who happens to be visiting from the neighborhood! Using his privileges as a child, Maseo skillfully deceives the grown-up sisters and tries all sorts of sexual harassment. Stay tuned!
