BACJ-107 Cunnilingus-loving big-ass sisters' sharehouse dream life where I'm kept as a lickspittle

I am a dog kept in a women-only share house for licking. I serve two sisters every day with all my heart: Marika-san, who has a fluffy big ass, and Sarara-san, who has a plump big ass. Sometimes I perform cunnilingus while being praised with kind words, and other times I am strictly disciplined with face-sitting that makes me suffocate. Although we are supposed to have a rotating cunnilingus shift schedule, the sisters' strong sex drive means they can't keep to the order… Often, I am forced into a 3P cunnilingus service by both of them. Every day, my balls dry up as I ejaculate while having my face smashed by big asses. Such a happy daily life.
