[MIRD-258] Once a month, my uncle's house sleepover party will let me drink his pee for 100 yen. A harem of flat-chested nieces. Kana Yura, Hikaru Minazuki, and Tsubomi Mochizuki. (Censored)

[I want to be showered with pure, shaved piss! I want to drink it! I want to drown in it!!] Because of their parents' work, three close nieces come to stay at their uncle's house in the countryside once a month. The uncle, who loves pee and his nieces, gives 100 yen to the three who beg for pocket money, and in exchange, all three of them splash their holy water on him at the same time! The nieces get so excited for just 100 yen that they get their faces and bodies soaked, and they drink all the pee and tease him, making every day the best! Today, he ejaculates again in the fresh, clear pee that only his nieces can produce! Ejaculation!!
