Aneki... My Sweet Elder Sister Senior 1 Saki Senpaiあねき…「早紀先輩」
Takumi-kun just cannot stop fantasizing about Saki-senpai, her voluptuous body just stand out anywhere. One day she talks to him in the train and become friends. Whenever he can Takumi-kun stares at her big tits and ass (and camel toes), always getting a hard on. Certain day Takumi-kun manages to get Saki-senpai underwear, he get home and masturbates immediately with it. The next day he cannot take more and tries to peep at her in the toilet, to his surprise he finds her masturbating....from this day on Saki-senpai and Takumi-kun would share all their fetishes and to both of them surprise they both share the same fetish...masturbating with underwear!!!
