[Subjective work!] Every day I get excited just living with my brother's wife Yuki. I got caught jerking off in secret! Since then, I've been living a life where my sister-in-law controls my ejaculations! While being made to hold back my ejaculation, I'm controlled by whispers like 'edge' and 'countdown' in my ear. My brother's wife also enjoys teasing me, and she even controls my internal ejaculations in secret from my brother...!
