Himitsu no Kakurenbo Ecchi ~Spats Shoujo to Kakurenbochuu ni Noumitsu Seikou!? Boku to Naisho de Sex Shiyo?~

Natsuki is bored of the same ol' hide and seek with girls. She'd rather mingle with the boys and calls herself the boyish pronoun "boku". Until now it's been a platonic interest, but lately... "Hey do you like, wanna... hide your thingie with me?" A tomboy loli in spats spices up the game with s-e-c-r-e-t e-c-c-h-i.
