One day, I started taking care of my niece sisters. The younger sister, Kurumi, was always curious about sex and would try to touch my cock whenever she had the chance. One day, her older sister Mao caught her in the act. Already pent-up with desire, Mao became even more aroused and started giving me a blowjob, sucking my hard cock. Their passionate behavior drove me wild with excitement. Then one morning, I woke up to find both sisters already sucking my morning wood. Led by the experienced older sister, we began practicing sex—thrilled by the big tits of these gorgeous sisters, their pussies, blowjobs, and titty fucks. I fucked the younger sister's inexperienced pussy, taking her virginity, then moved on to the older sister's filthy, wet cunt. I kept coming inside both of them, creampie after creampie, like a creampie feast. These insanely horny sisters gave me my first incestuous hard-on, and the overwhelming pleasure left me lost in ecstasy, not caring about anything else.
