Hopuhopu Team - Punishment! Touching Little Sis-chan Version 1.01 (eng) - Adult Sex Game

Half-Japanese girl Kunon Tsukushi Sunohara just moved into the neighborhood.
In her old hat and trainers, she follows around "big bro" like a loyal pet.
While playing footsies, her foot touches his crotch...

The sexually pure Kunon then starts to receive masturbation instruction,
electro-punishment, no-panty leg-raising punishment, cunnilingus, and more...
Finally, her breasts get some love too...
