I'm a college student and I'm being used by my childhood friend Saki-chan for a naughty reward ... I'm tempted by a cute smile ... I just want to see Omako and I lose the temptation. Saki-chan's older sister, Aki, who saw such a pitiful appearance, gently advised me, "Be firm !?", but she tempted me with a lascivious face to eliminate her frustration. In the end, I couldn't overcome either temptation and became a sexual processing pet of my horny beautiful sisters ...
